-#########################
-Installation Instructions
-#########################
-
-CodeIgniter is installed in four steps:
-
-#. Unzip the package.
-#. Upload the CodeIgniter folders and files to your server. Normally the
- *index.php* file will be at your root.
-#. Open the *application/config/config.php* file with a text editor and
- set your base URL. If you intend to use encryption or sessions, set
- your encryption key.
-#. If you intend to use a database, open the
- *application/config/database.php* file with a text editor and set your
- database settings.
-
-If you wish to increase security by hiding the location of your
-CodeIgniter files you can rename the system and application folders to
-something more private. If you do rename them, you must open your main
-*index.php* file and set the ``$system_path`` and ``$application_folder``
-variables at the top of the file with the new name you've chosen.
-
-For the best security, both the system and any application folders
-should be placed above web root so that they are not directly accessible
-via a browser. By default, *.htaccess* files are included in each folder
-to help prevent direct access, but it is best to remove them from public
-access entirely in case the web server configuration changes or doesn't
-abide by the *.htaccess*.
-
-If you would like to keep your views public it is also possible to move
-the views folder out of your application folder.
-
-After moving them, open your main index.php file and set the
-``$system_path``, ``$application_folder`` and ``$view_folder`` variables,
-preferably with a full path, e.g. '*/www/MyUser/system*'.
-
-One additional measure to take in production environments is to disable
-PHP error reporting and any other development-only functionality. In
-CodeIgniter, this can be done by setting the ``ENVIRONMENT`` constant, which
-is more fully described on the :doc:`security
-page <../general/security>`.
-
-That's it!
-
-If you're new to CodeIgniter, please read the :doc:`Getting
-Started <../overview/getting_started>` section of the User Guide
-to begin learning how to build dynamic PHP applications. Enjoy!

-Troubleshooting
-###############
-
-If you find that no matter what you put in your URL only your default
-page is loading, it might be that your server does not support the
-REQUEST_URI variable needed to serve search-engine friendly URLs. As a
-first step, open your *application/config/config.php* file and look for
-the URI Protocol information. It will recommend that you try a couple
-alternate settings. If it still doesn't work after you've tried this
-you'll need to force CodeIgniter to add a question mark to your URLs. To
-do this open your *application/config/config.php* file and change this::
-
- $config['index_page'] = "index.php";
-
-To this::
-
- $config['index_page'] = "index.php?";

-#########################
-Upgrading from 1.2 to 1.3
-#########################
-
-.. note:: The instructions on this page assume you are running version
- 1.2. If you have not upgraded to that version please do so first.
-
-Before performing an update you should take your site offline by
-replacing the index.php file with a static one.
-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace the following directories in your "system" folder with the new
-versions:
-
-.. note:: If you have any custom developed files in these folders please
- make copies of them first.
-
-- application/**models**/ (new for 1.3)
-- codeigniter (new for 1.3)
-- drivers
-- helpers
-- init
-- language
-- libraries
-- plugins
-- scaffolding
-
-Step 2: Update your error files
-===============================
-
-Version 1.3 contains two new error templates located in
-application/errors, and for naming consistency the other error templates
-have been renamed.
-
-If you **have not** customized any of the error templates simply replace
-this folder:
-
-- application/errors/
-
-If you **have** customized your error templates, rename them as follows:
-
-- 404.php = error_404.php
-- error.php = error_general.php
-- error_db.php (new)
-- error_php.php (new)
-
-Step 3: Update your index.php file
-==================================
-
-Please open your main index.php file (located at your root). At the very
-bottom of the file, change this::
-
- require_once BASEPATH.'libraries/Front_controller'.EXT;
-
-To this::
-
- require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;
-
-Step 4: Update your config.php file
-===================================
-
-Open your application/config/config.php file and add these new items::
-
-
- /*
- |------------------------------------------------
- | URL suffix
- |------------------------------------------------
- |
- | This option allows you to add a suffix to all URLs.
- | For example, if a URL is this:
- |
- | example.com/index.php/products/view/shoes
- |
- | You can optionally add a suffix, like ".html",
- | making the page appear to be of a certain type:
- |
- | example.com/index.php/products/view/shoes.html
- |
- */
- $config['url_suffix'] = "";
-
-
- /*
- |------------------------------------------------
- | Enable Query Strings
- |------------------------------------------------
- |
- | By default CodeIgniter uses search-engine and
- | human-friendly segment based URLs:
- |
- | example.com/who/what/where/
- |
- | You can optionally enable standard query string
- | based URLs:
- |
- | example.com?who=me&what=something&where=here
- |
- | Options are: TRUE or FALSE (boolean)
- |
- | The two other items let you set the query string "words"
- | that will invoke your controllers and functions:
- | example.com/index.php?c=controller&m=function
- |
- */
- $config['enable_query_strings'] = FALSE;
- $config['controller_trigger'] = 'c';
- $config['function_trigger'] = 'm';
-
-Step 5: Update your database.php file
-=====================================
-
-Open your application/config/database.php file and add these new items::
-
-
- $db['default']['dbprefix'] = "";
- $db['default']['active_r'] = TRUE;
-
-Step 6: Update your user guide
-==============================
-
-Please also replace your local copy of the user guide with the new
-version.

-
-As of version 1.3.3, CodeIgniter does **not** connect automatically to
-your database when a model is loaded. This allows you greater
-flexibility in determining which databases you would like used with your
-models. If your application is not connecting to your database prior to
-a model being loaded you will have to update your code. There are
-several options for connecting, :doc:`as described

-Before performing an update you should take your site offline by

-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace these files and directories in your "system" folder with the new

-
-- system/codeigniter
-- system/database
-- system/helpers
-- system/language
-- system/libraries
-
-.. note:: If you have any custom developed files in these folders please
- make copies of them first.
-
-Step 2: Update your Session Table
-=================================
-
-If you are using the Session class in your application, AND if you are
-storing session data to a database, you must add a new column named
-user_data to your session table. Here is an example of what this column
-might look like for MySQL::
-
- user_data text NOT NULL
-
-To add this column you will run a query similar to this::
-
- ALTER TABLE `ci_sessions` ADD `user_data` text NOT NULL
-
-You'll find more information regarding the new Session functionality in
-the :doc:`Session class <../libraries/sessions>` page.
-
-Step 3: Update your Validation Syntax
-=====================================
-
-This is an **optional**, but recommended step, for people currently
-using the Validation class. CI 1.7 introduces a new :doc:`Form Validation
-class <../libraries/form_validation>`, which deprecates the old
-Validation library. We have left the old one in place so that existing
-applications that use it will not break, but you are encouraged to
-migrate to the new version as soon as possible. Please read the user
-guide carefully as the new library works a little differently, and has
-several new features.
-
-Step 4: Update your user guide
-==============================
-
-Please replace your local copy of the user guide with the new version,
-including the image files.

-
-*******************
-Update Instructions
-*******************
-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace all files and directories in your "system" folder **except**
-your application folder.
-
-.. note:: If you have any custom developed files in these folders please
- make copies of them first.
-
-Step 2: Adjust get_dir_file_info() where necessary
-=====================================================
-
-Version 2.0.0 brings a non-backwards compatible change to
-get_dir_file_info() in the :doc:`File
-Helper <../helpers/file_helper>`. Non-backwards compatible changes
-are extremely rare in CodeIgniter, but this one we feel was warranted
-due to how easy it was to create serious server performance issues. If
-you *need* recursiveness where you are using this helper function,
-change such instances, setting the second parameter, $top_level_only
-to FALSE::
-
- get_dir_file_info('/path/to/directory', FALSE);
-
-Step 3: Convert your Plugins to Helpers
-=======================================
-
-2.0.0 gets rid of the "Plugin" system as their functionality was
-identical to Helpers, but non-extensible. You will need to rename your
-plugin files from filename_pi.php to filename_helper.php, move them to
-your helpers folder, and change all instances of::
-
- $this->load->plugin('foo');
-
-to ::
-
- $this->load->helper('foo');
-
-
-Step 4: Update stored encrypted data
-====================================
-
-.. note:: If your application does not use the Encrypt library, does
- not store Encrypted data permanently, or is on an environment that does
- not support Mcrypt, you may skip this step.
-
-The Encrypt library has had a number of improvements, some for
-encryption strength and some for performance, that has an unavoidable
-consequence of making it no longer possible to decode encrypted data
-produced by the original version of this library. To help with the
-transition, a new method has been added, encode_from_legacy() that
-will decode the data with the original algorithm and return a re-encoded
-string using the improved methods. This will enable you to easily
-replace stale encrypted data with fresh in your applications, either on
-the fly or en masse.
-
-Please read :doc:`how to use this
-method <../libraries/encrypt>` in the Encrypt library
-documentation.
-
-Step 5: Remove loading calls for the compatibility helper.
-==========================================================
-
-The compatibility helper has been removed from the CodeIgniter core. All
-methods in it should be natively available in supported PHP versions.
-
-Step 6: Update Class extension
-==============================
-
-All core classes are now prefixed with CI\_. Update Models and
-Controllers to extend CI_Model and CI_Controller, respectively.
-
-Step 7: Update Parent Constructor calls
-=======================================
-
-All native CodeIgniter classes now use the PHP 5 \__construct()
-convention. Please update extended libraries to call
-parent::\__construct().
-
-Step 8: Move any core extensions to application/core
-====================================================
-
-Any extensions to core classes (e.g. MY_Controller.php) in your
-application/libraries folder must be moved to the new
-application/core folder.
-
-Step 9: Update your user guide
-==============================
-
-Please replace your local copy of the user guide with the new version,
-including the image files.
-
-
-************
-Update Notes
-************
-
-Please refer to the :ref:`2.0.0 Change Log <2.0.0-changelog>` for full
-details, but here are some of the larger changes that are more likely to
-impact your code:
-
-- Scaffolding has been removed.
-- The CAPTCHA plugin in now a :doc:`helper </helpers/captcha_helper>`.
-- The JavaScript calendar plugin was removed.
-- The *system/cache* and *system/logs* directories are now in the application
- directory.
-- The Validation class has been removed. Please see the
- :doc:`Form Validation library </libraries/form_validation>`
-- "default" is now a reserved name.
-- The xss_clean() function has moved to the :doc:`Security Class
- </libraries/security>`.
-- do_xss_clean() now returns FALSE if the uploaded file fails XSS checks.
-- The :doc:`Session Class </libraries/sessions>` requires now the use of an
- encryption key set in the config file.
-- The following deprecated Active Record functions have been removed:
- ``orwhere``, ``orlike``, ``groupby``, ``orhaving``, ``orderby``,
- ``getwhere``.
-- ``_drop_database()`` and ``_create_database()`` functions have been removed
- from the db utility drivers.
-- The ``dohash()`` function of the :doc:`Security helper
- </helpers/security_helper>`
- has been renamed to ``do_hash()`` for naming consistency.
-
-The config folder
-=================
-
-The following files have been changed:
-
-- config.php
-- database.php
-- mimes.php
-- routes.php
-- user_agents.php
-
-The following files have been added:
-
-- foreign_chars.php
-- profiler.php \ No newline at end of file

-This config file has been updated to contain more mime types, please
-copy it to application/config/mimes.php.
-
-Step 3: Check for forms posting to default controller
-=====================================================
-
-The default behavior for form_open() when called with no parameters
-used to be to post to the default controller, but it will now just leave
-an empty action="" meaning the form will submit to the current URL. If
-submitting to the default controller was the expected behavior it will
-need to be changed from::
-
- echo form_open(); //<form action="" method="post" accept-charset="utf-8">
-
-to use either a / or base_url()::
-
- echo form_open('/'); //<form action="http://example.com/index.php/" method="post" accept-charset="utf-8">
- echo form_open(base_url()); //<form action="http://example.com/" method="post" accept-charset="utf-8">

-Upgrading from 2.0.2 to 2.0.3
-#############################
-
-Before performing an update you should take your site offline by
-replacing the index.php file with a static one.
-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace all files and directories in your "system" folder and replace
-your index.php file. If any modifications were made to your index.php
-they will need to be made fresh in this new one.
-
-.. note:: If you have any custom developed files in these folders please
- make copies of them first.
-
-Step 2: Update your main index.php file
-=======================================
-
-If you are running a stock index.php file simply replace your version
-with the new one.
-
-If your index.php file has internal modifications, please add your
-modifications to the new file and use it.
-
-Step 3: Replace config/user_agents.php
-=======================================
-
-This config file has been updated to contain more user agent types,
-please copy it to application/config/user_agents.php.
-
-Step 4: Change references of the EXT constant to ".php"
-=======================================================
-
-.. note:: The EXT Constant has been marked as deprecated, but has not
- been removed from the application. You are encouraged to make the
- changes sooner rather than later.
-
-Step 5: Remove APPPATH.'third_party' from autoload.php
-=======================================================
-
-Open application/config/autoload.php, and look for the following::
-
- $autoload['packages'] = array(APPPATH.'third_party');
-
-If you have not chosen to load any additional packages, that line can be
-changed to::
-
- $autoload['packages'] = array();
-
-Which should provide for nominal performance gains if not autoloading
-packages.
-
-Update Sessions Database Tables
-===============================
-
-If you are using database sessions with the CI Session Library, please
-update your ci_sessions database table as follows::
-
- CREATE INDEX last_activity_idx ON ci_sessions(last_activity);
- ALTER TABLE ci_sessions MODIFY user_agent VARCHAR(120);

-Upgrading from 2.2.x to 3.0.x
-#############################
-
-Before performing an update you should take your site offline by replacing the index.php file with a static one.
-
-*************************************
-Step 1: Update your CodeIgniter files
-*************************************
-
-**Replace** all files and directories in your *system/* directory and
-replace your index.php file. If any modifications were made to your
-index.php they will need to be made fresh in this new one.
-
-.. important:: You have to delete the old *system/* directory first and
- then put the new one in its place. A simple copy-paste may cause
- issues.
-
-.. note:: If you have any custom developed files in these folders please
- make copies of them first.
-
-**************************************
-Step 2: Update your classes file names
-**************************************
-
-Starting with CodeIgniter 3.0, all class filenames (libraries, drivers, controllers
-and models) must be named in a Ucfirst-like manner or in other words - they must
-start with a capital letter.
-
-For example, if you have the following library file:
-
- application/libraries/mylibrary.php
-
-... then you'll have to rename it to:
-
- application/libraries/Mylibrary.php
-
-The same goes for driver libraries and extensions and/or overrides of CodeIgniter's
-own libraries and core classes.
-
- application/libraries/MY_email.php
- application/core/MY_log.php
-
-The above files should respectively be renamed to the following:
-
- application/libraries/MY_Email.php
- application/core/MY_Log.php
-
-Controllers:
-
- application/controllers/welcome.php -> application/controllers/Welcome.php
-
-Models:
-
- application/models/misc_model.php -> application/models/Misc_model.php
-
-Please note that this DOES NOT affect directories, configuration files, views,
-helpers, hooks and anything else - it is only applied to classes.
-
-You must now follow just one simple rule - class names in Ucfirst and everything else
-in lowercase.
-
-********************************
-Step 3: Replace config/mimes.php
-********************************
-
-This config file has been updated to contain more user mime-types, please copy
-it to *application/config/mimes.php*.
-
-**************************************************************
-Step 4: Remove $autoload['core'] from your config/autoload.php
-**************************************************************
-
-Use of the ``$autoload['core']`` config array has been deprecated as of CodeIgniter 1.4.1 and is now removed.
-Move any entries that you might have listed there to ``$autoload['libraries']`` instead.
-
-***************************************************
-Step 5: Move your Log class overrides or extensions
-***************************************************
-
-The Log Class is considered as a "core" class and is now located in the
-**system/core/** directory. Therefore, in order for your Log class overrides
-or extensions to work, you need to move them to **application/core/**:
-
- application/libraries/Log.php -> application/core/Log.php
- application/libraries/MY_Log.php -> application/core/MY_Log.php
-
-*****************************************
-Step 6: Update your Session library usage
-*****************************************
-
-The :doc:`Session Library </libraries/sessions>` has been completely
-re-written in CodeIgniter 3 and now comes with a bunch of new features,
-but that also means that there are changes that you should make ...
-
-Most notably, the library now uses separate storage drivers instead of
-always relying on (encrypted) cookies.
-In fact, cookies as storage have now been removed and you must always use
-some kind of server-side storage engine, with the file-system being the
-default option.
-
-The Session Class now utilizes PHP's own mechanisms for building custom
-session handlers, which also means that your session data is now
-accessible via the ``$_SESSION`` superglobal (though, we've kept the
-possibility to use it as "userdata", like you've done until now).
-
-A few configuration options have been removed and a few have been added.
-You should really read the whole :doc:`Session library manual
-</libraries/sessions>` for the details, but here's a short list of changes
-that you should make:
-
- - Set your ``$config['sess_driver']`` value
-
- It will default to 'files', unless you've previously used
- ``$config['sess_use_database']``, in which case it will be set to
- 'database'.
-
- - Set a ``$config['sess_save_path']`` value
-
- For the 'database' driver, a fallback to ``$config['sess_table_name']``
- is in place, but otherwise requires you to read the manual for the
- specific driver of your choice.
-
- - Update your ``ci_sessions`` table ('database' driver only)
-
- The table structure has changed a bit, and more specifically:
-
- - ``session_id`` field is renamed to ``id``
- - ``user_agent`` field is dropped
- - ``user_data`` field is renamed to ``data`` and under MySQL is now of type BLOB
- - ``last_activity`` field is renamed to ``timestamp``
-
- This is accompanied by a slight change in the table indexes too, so
- please read the manual about the `Session Database Driver
- <../libraries/sessions.html#database-driver>`_ for more information.
-
- .. important:: Only MySQL and PostgreSQL are officially supported
- now. Other databases may still work, but due to lack of advisory
- locking features, they are unsafe for concurrent requests and
- you should consider using another driver instead.
-
- - Remove ``$config['sess_match_useragent']``
-
- The user-agent string is input supplied by the user's browser, or in
- other words: client side input. As such, it is an ineffective feature
- and hence why it has been removed.
-
- - Remove ``$config['sess_encrypt_cookie']``
-
- As already noted, the library no longer uses cookies as a storage
- mechanism, which renders this option useless.
-
- - Remove ``$config['sess_expire_on_close']``
-
- This option is still usable, but only for backwards compatibility
- purposes and it should be otherwise removed. The same effect is
- achieved by setting ``$config['sess_expiration']`` to 0.
-
- - Check "flashdata" for collisions with "userdata"
-
- Flashdata is now just regular "userdata", only marked for deletion on
- the next request. In other words: you can't have both "userdata" and
- "flashdata" with the same name, because it's the same thing.
-
- - Check usage of session metadata
-
- Previously, you could access the 'session_id', 'ip_address',
- 'user_agent' and 'last_activity' metadata items as userdata.
- This is no longer possible, and you should read the notes about
- `Session Metadata <../libraries/sessions.html#accessing-session-metadata>`_
- if your application relies on those values.
-
- - Check ``unset_userdata()`` usage
-
- Previously, this method used to accept an associative array of
- ``'key' => 'dummy value'`` pairs for unsetting multiple keys. That
- however makes no sense and you now have to pass *only* the keys, as
- the elements of an array.
-
- ::
-
- // Old
- $this->session->unset_userdata(array('item' => '', 'item2' => ''));
-
- // New
- $this->session->unset_userdata(array('item', 'item2'));
-
-Finally, if you have written a Session extension, you must now move it to
-the *application/libraries/Session/* directory, although chances are that
-it will now also have to be re-factored.
-
-***************************************
-Step 7: Update your config/database.php
-***************************************
-
-Due to 3.0.0's renaming of Active Record to Query Builder, inside your
-**config/database.php**, you will need to rename the ``$active_record``
-variable to ``$query_builder``::
-
- $active_group = 'default';
- // $active_record = TRUE;
- $query_builder = TRUE;
-
-************************************
-Step 8: Replace your error templates
-************************************
-
-In CodeIgniter 3.0, the error templates are now considered as views and have been moved to the
-*application/views/errors* directory.
-
-Furthermore, we've added support for CLI error templates in plain-text format that unlike HTML,
-is suitable for the command line. This of course requires another level of separation.
-
-It is safe to move your old templates from *application/errors* to *application/views/errors/html*,
-but you'll have to copy the new *application/views/errors/cli* directory from the CodeIgniter archive.
-
-******************************************
-Step 9: Update your config/routes.php file
-******************************************
-
-Routes containing :any
-======================
-
-Historically, CodeIgniter has always provided the **:any** wildcard in
-routing, with the intention of providing a way to match any character
-**within** an URI segment.
-
-However, the **:any** wildcard is actually just an alias for a regular
-expression and used to be executed in that manner as **.+**. This is
-considered a bug, as it also matches the / (forward slash) character, which
-is the URI segment delimiter and that was never the intention.
-
-In CodeIgniter 3, the **:any** wildcard will now represent **[^/]+**, so
-that it will not match a forward slash.
-
-There are certainly many developers that have utilized this bug as an actual
-feature. If you're one of them and want to match a forward slash, please use
-the **.+** regular expression::
-
- (.+) // matches ANYTHING
- (:any) // matches any character, except for '/'
-
-Directories and 'default_controller', '404_override'
-====================================================
-
-As you should know, the ``$route['default_controller']`` and
-``$route['404_override']`` settings accept not only a controller name, but
-also *controller/method* pairs. However, a bug in the routing logic has
-made it possible for some users to use that as *directory/controller*
-instead.
-
-As already said, this behavior was incidental and was never intended, nor
-documented. If you've relied on it, your application will break with
-CodeIgniter 3.0.
-
-Another notable change in version 3 is that 'default_controller' and
-'404_override' are now applied *per directory*. To explain what this means,
-let's take the following example::
-
- $route['default_controller'] = 'main';
-
-Now, assuming that your website is located at *example.com*, you already
-know that if a user visits ``http://example.com/``, the above setting will
-cause your 'Main' controller to be loaded.
-
-However, what happens if you have an *application/controllers/admin/*
-directory and the user visits ``http://example.com/admin/``?
-In CodeIgniter 3, the router will look for a 'Main' controller under the
-admin/ directory as well. If not found, a Not Found (404) will be triggered.
-
-The same rule applies to the '404_override' setting.
-
-*************************************************************************
-Step 10: Many functions now return NULL instead of FALSE on missing items
-*************************************************************************
-
-Many methods and functions now return NULL instead of FALSE when the required items don't exist:
-
- - :doc:`Common functions <../general/common_functions>`
-
- - config_item()
-
- - :doc:`Config Class <../libraries/config>`
-
- - config->item()
- - config->slash_item()
-
- - :doc:`Input Class <../libraries/input>`
-
- - input->get()
- - input->post()
- - input->get_post()
- - input->cookie()
- - input->server()
- - input->input_stream()
- - input->get_request_header()
-
- - :doc:`Session Class <../libraries/sessions>`
-
- - session->userdata()
- - session->flashdata()
-
- - :doc:`URI Class <../libraries/uri>`
-
- - uri->segment()
- - uri->rsegment()
-
- - :doc:`Array Helper <../helpers/array_helper>`
-
- - element()
- - elements()
-
-*******************************
-Step 11: Usage of XSS filtering
-*******************************
-
-Many functions in CodeIgniter allow you to use its XSS filtering feature
-on demand by passing a boolean parameter. The default value of that
-parameter used to be boolean FALSE, but it is now changed to NULL and it
-will be dynamically determined by your ``$config['global_xss_filtering']``
-value.
-
-If you used to manually pass a boolean value for the ``$xss_filter``
-parameter or if you've always had ``$config['global_xss_filtering']`` set
-to FALSE, then this change doesn't concern you.
-
-Otherwise however, please review your usage of the following functions:
-
- - :doc:`Input Library <../libraries/input>`
-
- - input->get()
- - input->post()
- - input->get_post()
- - input->cookie()
- - input->server()
- - input->input_stream()
-
- - :doc:`Cookie Helper <../helpers/cookie_helper>` :php:func:`get_cookie()`
-
-.. important:: Another related change is that the ``$_GET``, ``$_POST``,
- ``$_COOKIE`` and ``$_SERVER`` superglobals are no longer
- automatically overwritten when global XSS filtering is turned on.
-
-*************************************************
-Step 12: Check for potential XSS issues with URIs
-*************************************************
-
-The :doc:`URI Library <../libraries/uri>` used to automatically convert
-a certain set of "programmatic characters" to HTML entities when they
-are encountered in a URI segment.
-
-This was aimed at providing some automatic XSS protection, in addition
-to the ``$config['permitted_uri_chars']`` setting, but has proven to be
-problematic and is now removed in CodeIgniter 3.0.
-
-If your application has relied on this feature, you should update it to
-filter URI segments through ``$this->security->xss_clean()`` whenever you
-output them.
-
-****************************************************************
-Step 13: Check for usage of the 'xss_clean' Form validation rule
-****************************************************************
-
-A largely unknown rule about XSS cleaning is that it should *only be
-applied to output*, as opposed to input data.
-
-We've made that mistake ourselves with our automatic and global XSS cleaning
-feature (see previous step about XSS above), so now in an effort to discourage that
-practice, we're also removing 'xss_clean' from the officially supported
-list of :doc:`form validation <../libraries/form_validation>` rules.
-
-Because the :doc:`Form Validation library <../libraries/form_validation>`
-generally validates *input* data, the 'xss_clean' rule simply doesn't
-belong in it.
-
-If you really, really need to apply that rule, you should now also load the
-:doc:`Security Helper <../helpers/security_helper>`, which contains
-``xss_clean()`` as a regular function and therefore can be also used as
-a validation rule.
-
-********************************************************
-Step 14: Update usage of Input Class's get_post() method
-********************************************************
-
-Previously, the :doc:`Input Class <../libraries/input>` method ``get_post()``
-was searching first in POST data, then in GET data. This method has been
-modified so that it searches in GET then in POST, as its name suggests.
-
-A method has been added, ``post_get()``, which searches in POST then in GET, as
-``get_post()`` was doing before.
-
-********************************************************************
-Step 15: Update usage of Directory Helper's directory_map() function
-********************************************************************
-
-In the resulting array, directories now end with a trailing directory
-separator (i.e. a slash, usually).
-
-*************************************************************
-Step 16: Update usage of Database Forge's drop_table() method
-*************************************************************
-
-Up until now, ``drop_table()`` added an IF EXISTS clause by default or it didn't work
-at all with some drivers. In CodeIgniter 3.0, the IF EXISTS condition is no longer added
-by default and has an optional second parameter that allows that instead and is set to
-FALSE by default.
-
-If your application relies on IF EXISTS, you'll have to change its usage.
-
-::
-
- // Now produces just DROP TABLE `table_name`
- $this->dbforge->drop_table('table_name');
-
- // Produces DROP TABLE IF EXISTS `table_name`
- $this->dbforge->drop_table('table_name', TRUE);
-
-.. note:: The given example uses MySQL-specific syntax, but it should work across
- all drivers with the exception of ODBC.
-
-***********************************************************
-Step 17: Change usage of Email library with multiple emails
-***********************************************************
-
-The :doc:`Email Library <../libraries/email>` will automatically clear the
-set parameters after successfully sending emails. To override this behaviour,
-pass FALSE as the first parameter in the ``send()`` method:
-
-::
-
- if ($this->email->send(FALSE))
- {
- // Parameters won't be cleared
- }
-
-***************************************************
-Step 18: Update your Form_validation language lines
-***************************************************
-
-Two improvements have been made to the :doc:`Form Validation Library
-<../libraries/form_validation>`'s :doc:`language <../libraries/language>`
-files and error messages format:
-
- - :doc:`Language Library <../libraries/language>` line keys now must be
- prefixed with **form_validation_** in order to avoid collisions::
-
- // Old
- $lang['rule'] = ...
-
- // New
- $lang['form_validation_rule'] = ...
-
- - The error messages format has been changed to use named parameters, to
- allow more flexibility than what `sprintf()` offers::
-
- // Old
- 'The %s field does not match the %s field.'
-
- // New
- 'The {field} field does not match the {param} field.'
-
-.. note:: The old formatting still works, but the non-prefixed line keys
- are DEPRECATED and scheduled for removal in CodeIgniter 3.1+.
- Therefore you're encouraged to update its usage sooner rather than
- later.
-
-************************************************************
-Step 19: Make sure your 'base_url' config value is not empty
-************************************************************
-
-When ``$config['base_url']`` is not set, CodeIgniter tries to automatically
-detect what your website's base URL is. This is done purely for convenience
-when you are starting development of a new application.
-
-Auto-detection is never reliable and also has security implications, which
-is why you should **always** have it manually configured!
-
-One of the changes in CodeIgniter 3.0.3 is how this auto-detection works,
-and more specifically it now falls back to the server's IP address instead
-of the hostname requested by the client. Therefore, if you've ever relied
-on auto-detection, it will change how your website works now.
-
-In case you need to allow e.g. multiple domains, or both http:// and
-https:// prefixes to be dynamically used depending on the request,
-remember that *application/config/config.php* is still a PHP script, in
-which you can create this logic with a few lines of code. For example::
-
- $allowed_domains = array('domain1.tld', 'domain2.tld');
- $default_domain = 'domain1.tld';
-
- if (in_array($_SERVER['HTTP_HOST'], $allowed_domains, TRUE))
- {
- $domain = $_SERVER['HTTP_HOST'];
- }
- else
- {
- $domain = $default_domain;
- }
-
- if ( ! empty($_SERVER['HTTPS']))
- {
- $config['base_url'] = 'https://'.$domain;
- }
- else
- {
- $config['base_url'] = 'http://'.$domain;
- }
-
-
-****************************************************************
-Step 20: Remove usage of (previously) deprecated functionalities
-****************************************************************
-
-In addition to the ``$autoload['core']`` configuration setting, there's a
-number of other functionalities that have been removed in CodeIgniter 3.0.0:
-
-The SHA1 library
-================
-
-The previously deprecated SHA1 library has been removed, alter your code to use PHP's native
-``sha1()`` function to generate a SHA1 hash.
-
-Additionally, the ``sha1()`` method in the :doc:`Encrypt Library <../libraries/encrypt>` has been removed.
-
-The EXT constant
-================
-
-Usage of the ``EXT`` constant has been deprecated since dropping support for PHP 4. There's no
-longer a need to maintain different filename extensions and in this new CodeIgniter version,
-the ``EXT`` constant has been removed. Use just '.php' instead.
-
-Smiley helper
-=============
-
-The :doc:`Smiley Helper <../helpers/smiley_helper>` is a legacy feature from EllisLab's
-ExpressionEngine product. However, it is too specific for a general purpose framework like
-CodeIgniter and as such it is now deprecated.
-
-Also, the previously deprecated ``js_insert_smiley()`` (since version 1.7.2) is now removed.
-
-The Encrypt library
-===================
-
-Following numerous vulnerability reports, the :doc:`Encrypt Library <../libraries/encrypt>` has
-been deprecated and a new, :doc:`Encryption Library <../libraries/encryption>` is added to take
-its place.
-
-The new library requires either the `MCrypt extension <http://php.net/mcrypt>`_ (and /dev/urandom
-availability) or PHP 5.3.3 and the `OpenSSL extension <http://php.net/openssl>`_.
-While this might be rather inconvenient, it is a requirement that allows us to have properly
-implemented cryptographic functions.
-
-.. note:: The :doc:`Encrypt Library <../libraries/encrypt>` is still available for the purpose
- of keeping backwards compatibility.
-
-.. important:: You are strongly encouraged to switch to the new :doc:`Encryption Library
- <../libraries/encryption>` as soon as possible!
-
-The Cart library
-================
-
-The :doc:`Cart Library <../libraries/cart>`, similarly to the :doc:`Smiley Helper
-<../helpers/smiley_helper>` is too specific for CodeIgniter. It is now deprecated
-and scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: The library is still available, but you're strongly encouraged to remove its usage sooner
- rather than later.
-
-Database drivers 'mysql', 'sqlite', 'mssql', 'pdo/dblib'
-========================================================
-
-The **mysql** driver utilizes the old 'mysql' PHP extension, known for its aging code base and
-many low-level problems. The extension is deprecated as of PHP 5.5 and CodeIgniter deprecates
-it in version 3.0, switching the default configured MySQL driver to **mysqli**.
-
-Please use either the 'mysqli' or 'pdo/mysql' drivers for MySQL. The old 'mysql' driver will be
-removed at some point in the future.
-
-The **sqlite**, **mssql** and **pdo/dblib** (also known as pdo/mssql or pdo/sybase) drivers
-all depend on PHP extensions that for different reasons no longer exist since PHP 5.3.
-
-Therefore we are now deprecating these drivers as we will have to remove them in one of the next
-CodeIgniter versions. You should use the more advanced, **sqlite3**, **sqlsrv** or **pdo/sqlsrv**
-drivers respectively.
-
-.. note:: These drivers are still available, but you're strongly encouraged to switch to other ones
- sooner rather than later.
-
-Security helper do_hash()
-=========================
-
-:doc:`Security Helper <../helpers/security_helper>` function ``do_hash()`` is now just an alias for
-PHP's native ``hash()`` function. It is deprecated and scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
- rather than later.
-
-The $config['global_xss_filtering'] setting
-===========================================
-
-As already explained above, XSS filtering should not be done on input data,
-but on output instead. Therefore, the ``$config['global_xss_filtering']``,
-which automatically filters *input* data, is considered a bad practice and
-is now deprecated.
-
-Instead, you should manually escape any user-provided data via the
-:php:func:`xss_clean()` function when you need to output it, or use a
-library like `HTML Purifier <http://htmlpurifier.org/>`_ that does that
-for you.
-
-.. note:: The setting is still available, but you're strongly encouraged to
- remove its usage sooner rather than later.
-
-File helper read_file()
-=======================
-
-:doc:`File Helper <../helpers/file_helper>` function ``read_file()`` is now just an alias for
-PHP's native ``file_get_contents()`` function. It is deprecated and scheduled for removal in
-CodeIgniter 3.1+.
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
- rather than later.
-
-String helper repeater()
-========================
-
-:doc:`String Helper <../helpers/string_helper>` function :php:func:`repeater()` is now just an alias for
-PHP's native ``str_repeat()`` function. It is deprecated and scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
- rather than later.
-
-String helper trim_slashes()
-============================
-
-:doc:`String Helper <../helpers/string_helper>` function :php:func:`trim_slashes()` is now just an alias
-for PHP's native ``trim()`` function (with a slash passed as its second argument). It is deprecated and
-scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
- rather than later.
-
-Form helper form_prep()
-=======================
-
-:doc:`Form Helper <../helpers/form_helper>` function :php:func:`form_prep()`
-is now just an alias for :doc:`common function </general/common_functions>`
-:func:`html_escape()`. It is deprecated and will be removed in the future.
-
-Please use :php:func:`html_escape()` instead.
-
-.. note:: This function is still available, but you're strongly encouraged
- to remove its usage sooner rather than later.
-
-Email helper functions
-======================
-
-:doc:`Email Helper <../helpers/email_helper>` only has two functions
-
- - :php:func:`valid_email()`
- - :php:func:`send_email()`
-
-Both of them are now aliases for PHP's native ``filter_var()`` and ``mail()`` functions, respectively.
-Therefore the :doc:`Email Helper <../helpers/email_helper>` altogether is being deprecated and
-is scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: These functions are still available, but you're strongly encouraged to remove their usage
- sooner rather than later.
-
-Date helper standard_date()
-===========================
-
-:doc:`Date Helper <../helpers/date_helper>` function ``standard_date()`` is being deprecated due
-to the availability of native PHP `constants <http://php.net/manual/en/class.datetime.php#datetime.constants.types>`_,
-which when combined with ``date()`` provide the same functionality. Furthermore, they have the
-exact same names as the ones supported by ``standard_date()``. Here are examples of how to replace
-its usage:
-
-::
-
- // Old way
- standard_date(); // defaults to standard_date('DATE_RFC822', now());
-
- // Replacement
- date(DATE_RFC822, now());
-
- // Old way
- standard_date('DATE_ATOM', $time);
-
- // Replacement
- date(DATE_ATOM, $time);
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
- rather than later as it is scheduled for removal in CodeIgniter 3.1+.
-
-HTML helpers nbs(), br()
-========================
-
-:doc:`HTML Helper <../helpers/html_helper>` functions ``nbs()`` and ``br()`` are just aliases
-for the native ``str_repeat()`` function used with ``&nbsp;`` and ``<br >`` respectively.
-
-Because there's no point in just aliasing native PHP functions, they are now deprecated and
-scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: These functions are still available, but you're strongly encouraged to remove their usage
- sooner rather than later.
-
-Pagination library 'anchor_class' setting
-=========================================
-
-The :doc:`Pagination Library <../libraries/pagination>` now supports adding pretty much any HTML
-attribute to your anchors via the 'attributes' configuration setting. This includes passing the
-'class' attribute and using the separate 'anchor_class' setting no longer makes sense.
-As a result of that, the 'anchor_class' setting is now deprecated and scheduled for removal in
-CodeIgniter 3.1+.
-
-.. note:: This setting is still available, but you're strongly encouraged to remove its usage sooner
- rather than later.
-
-String helper random_string() types 'unique' and 'encrypt'
-==========================================================
-
-When using the :doc:`String Helper <../helpers/string_helper>` function :php:func:`random_string()`,
-you should no longer pass the **unique** and **encrypt** randomization types. They are only
-aliases for **md5** and **sha1** respectively and are now deprecated and scheduled for removal
-in CodeIgniter 3.1+.
-
-.. note:: These options are still available, but you're strongly encouraged to remove their usage
- sooner rather than later.
-
-URL helper url_title() separators 'dash' and 'underscore'
-=========================================================
-
-When using the :doc:`URL Helper <../helpers/url_helper>` function :php:func:`url_title()`, you
-should no longer pass **dash** or **underscore** as the word separator. This function will
-now accept any character and you should just pass the chosen character directly, so you
-should write '-' instead of 'dash' and '_' instead of 'underscore'.
-
-**dash** and **underscore** now act as aliases and are deprecated and scheduled for removal
-in CodeIgniter 3.1+.
-
-.. note:: These options are still available, but you're strongly encouraged to remove their usage
- sooner rather than later.
-
-Session Library method all_userdata()
-=====================================
-
-As seen in the :doc:`Change Log <../changelog>`, :doc:`Session Library <../libraries/sessions>`
-method ``userdata()`` now allows you to fetch all userdata by simply omitting its parameter::
-
- $this->session->userdata();
-
-This makes the ``all_userdata()`` method redudant and therefore it is now just an alias for
-``userdata()`` with the above shown usage and is being deprecated and scheduled for removal
-in CodeIgniter 3.1+.
-
-.. note:: This method is still available, but you're strongly encouraged to remove its usage
- sooner rather than later.
-
-Database Forge method add_column() with an AFTER clause
-=======================================================
-
-If you have used the **third parameter** for :doc:`Database Forge <../database/forge>` method
-``add_column()`` to add a field for an AFTER clause, then you should change its usage.
-
-That third parameter has been deprecated and scheduled for removal in CodeIgniter 3.1+.
-
-You should now put AFTER clause field names in the field definition array instead::
-
- // Old usage:
- $field = array(
- 'new_field' => array('type' => 'TEXT')
- );
-
- $this->dbforge->add_column('table_name', $field, 'another_field');
-
- // New usage:
- $field = array(
- 'new_field' => array('type' => 'TEXT', 'after' => 'another_field')
- );
-
- $this->dbforge->add_column('table_name', $field);
-
-.. note:: The parameter is still available, but you're strongly encouraged to remove its usage
- sooner rather than later.
-
-.. note:: This is for MySQL and CUBRID databases only! Other drivers don't support this
- clause and will silently ignore it.
-
-URI Routing methods fetch_directory(), fetch_class(), fetch_method()
-====================================================================
-
-With properties ``CI_Router::$directory``, ``CI_Router::$class`` and ``CI_Router::$method``
-being public and their respective ``fetch_*()`` no longer doing anything else to just return
-the properties - it doesn't make sense to keep them.
-
-Those are all internal, undocumented methods, but we've opted to deprecate them for now
-in order to maintain backwards-compatibility just in case. If some of you have utilized them,
-then you can now just access the properties instead::
-
- $this->router->directory;
- $this->router->class;
- $this->router->method;
-
-.. note:: Those methods are still available, but you're strongly encouraged to remove their usage
- sooner rather than later.
-
-Input library method is_cli_request()
-=====================================
-
-Calls to the ``CI_Input::is_cli_request()`` method are necessary at many places
-in the CodeIgniter internals and this is often before the :doc:`Input Library
-<../libraries/input>` is loaded. Because of that, it is being replaced by a common
-function named :php:func:`is_cli()` and this method is now just an alias.
-
-The new function is both available at all times for you to use and shorter to type.
-
-::
-
- // Old
- $this->input->is_cli_request();
-
- // New
- is_cli();
-
-``CI_Input::is_cli_request()`` is now now deprecated and scheduled for removal in
-CodeIgniter 3.1+.
-
-.. note:: This method is still available, but you're strongly encouraged to remove its usage
- sooner rather than later.
-
-Config library method system_url()
-==================================
-
-Usage of ``CI_Config::system_url()`` encourages insecure coding practices.
-Namely, your CodeIgniter *system/* directory shouldn't be publicly accessible
-from a security point of view.
-
-Because of this, this method is now deprecated and scheduled for removal in
-CodeIgniter 3.1+.
-
-.. note:: This method is still available, but you're strongly encouraged to remove its usage
- sooner rather than later.
-
-The Javascript library
-======================
-
-The :doc:`Javascript Library <../libraries/javascript>` has always had an
-'experimental' status and was never really useful, nor a proper solution.
-
-It is now deprecated and scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: This library is still available, but you're strongly encouraged to remove its usage
- sooner rather than later.
-
-Form Validation method prep_for_form()
-======================================
-
-The :doc:`Form Validation Library <../libraries/form_validation>` has a
-``prep_for_form()`` method, which is/can also be used as a rule in
-``set_rules()`` to automatically perform HTML encoding on input data.
-
-Automatically encoding input (instead of output) data is a bad practice in
-the first place, and CodeIgniter and PHP itself offer other alternatives
-to this method anyway.
-For example, :doc:`Form Helper <../helpers/form_helper>` functions will
-automatically perform HTML escaping when necessary.
-
-Therefore, the *prep_for_form* method/rule is pretty much useless and is now
-deprecated and scheduled for removal in 3.1+.
-
-.. note:: The method is still available, but you're strongly encouraged to
- remove its usage sooner rather than later.
-
-***********************************************************
-Step 21: Check your usage of Text helper highlight_phrase()
-***********************************************************
-
-The default HTML tag used by :doc:`Text Helper <../helpers/text_helper>` function
-:func:`highlight_phrase()` has been changed from ``<strong>`` to the new HTML5
-tag ``<mark>``.
-
-Unless you've used your own highlighting tags, this might cause trouble
-for your visitors who use older web browsers such as Internet Explorer 8.
-We therefore suggest that you add the following code to your CSS files
-in order to avoid backwards compatibility with old browsers::
-
- mark {
- background: #ff0;
- color: #000;
- };

-Upgrading from 3.0.6 to 3.1.0
-#############################
-
-Before performing an update you should take your site offline by
-replacing the index.php file with a static one.
-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace all files and directories in your *system/* directory.
-
-.. note:: If you have any custom developed files in these directories,
- please make copies of them first.
-
-Step 2: Check your PHP version
-==============================
-
-We recommend always running versions that are `currently supported
-<https://secure.php.net/supported-versions.php>`_, which right now is at least PHP 5.6.
-
-PHP 5.2.x versions are now officially not supported by CodeIgniter, and while 5.3.7+
-may be at least runnable, we strongly discourage you from using any PHP versions below
-the ones listed on the `PHP.net Supported Versions <https://secure.php.net/supported-versions.php>`_
-page.
-
-Step 3: If you're using the 'odbc' database driver, check for usage of Query Builder
-====================================================================================
-
-:doc:`Query Builder <../database/query_builder>` functionality and ``escape()`` can
-no longer be used with the 'odbc' database driver.
-
-This is because, due to its nature, the `ODBC extension for PHP <https://secure.php.net/odbc>`_
-does not provide a function that allows to safely escape user-supplied strings for usage
-inside an SQL query (which our :doc:`Query Builder <../database/query_builder>` relies on).
-
-Thus, user inputs MUST be bound, as shown in :doc:`Running Queries <../database/queries>`,
-under the "Query Bindings" section. \ No newline at end of file

-
-Replace all files and directories in your *system/* directory.
-
-.. note:: If you have any custom developed files in these directories,

-
-Step 2: Update your "ci_sessions" database table
-================================================
-
-If you're using the :doc:`Session Library </libraries/sessions>` with the
-'database' driver, you may have to ``ALTER`` your sessions table for your
-sessions to continue to work.
-
-.. note:: The table in question is not necessarily named "ci_sessions".
- It is what you've set as your ``$config['sess_save_path']``.
-
-This will only affect you if you've changed your ``session.hash_function``
-*php.ini* setting to something like 'sha512'. Or if you've been running
-an older CodeIgniter version on PHP 7.1+.
-
-It is recommended that you do this anyway, just to avoid potential issues
-in the future if you do change your configuration.
-
-Just execute the one of the following SQL queries, depending on your
-database::
-
- // MySQL:
- ALTER TABLE ci_sessions CHANGE id id varchar(128) NOT NULL;
-
- // PostgreSQL
- ALTER TABLE ci_sessions ALTER COLUMN id SET DATA TYPE varchar(128);

-=====================================
-
-Replace all files and directories in your *system/* directory.
-
-.. note:: If you have any custom developed files in these directories,

-
-Step 2: Remove usage of nice_date() helper (deprecation)
-========================================================
-
-The :doc:`Date Helper <../helpers/date_helper>` function ``nice_date()`` is
-no longer useful since the introduction of PHP's `DateTime classes
-<https://secure.php.net/datetime>`_
-
-You can replace it with the following:
-::
-
- DateTime::createFromFormat($input_format, $input_date)->format($desired_output_format);
-
-Thus, ``nice_date()`` is now deprecated and scheduled for removal in
-CodeIgniter 3.2+.
-
-.. note:: The function is still available, but you're strongly encouraged
- to remove its usage sooner rather than later.
-
-Step 3: Remove usage of $config['standardize_newlines']
-=======================================================
-
-The :doc:`Input Library <../libraries/input>` would optionally replace
-occurrences of `\r\n`, `\r`, `\n` in input data with whatever the ``PHP_EOL``
-value is on your system - if you've set ``$config['standardize_newlines']``
-to ``TRUE`` in your *application/config/config.php*.
-
-This functionality is now deprecated and scheduled for removal in
-CodeIgniter 3.2.+.
-
-.. note:: The functionality is still available, but you're strongly
- encouraged to remove its usage sooner rather than later.

-###################################
-Upgrading From Beta 1.0 to Beta 1.1
-###################################
-
-To upgrade to Beta 1.1 please perform the following steps:
-
-Step 1: Replace your index file
-===============================
-
-Replace your main index.php file with the new index.php file. Note: If
-you have renamed your "system" folder you will need to edit this info in
-the new file.
-
-Step 2: Relocate your config folder
-===================================
-
-This version of CodeIgniter now permits multiple sets of "applications"
-to all share a common set of backend files. In order to enable each
-application to have its own configuration values, the config directory
-must now reside inside of your application folder, so please move it
-there.
-
-Step 3: Replace directories
-===========================
-
-Replace the following directories with the new versions:
-
-- drivers
-- helpers
-- init
-- libraries
-- scaffolding
-
-Step 4: Add the calendar language file
-======================================
-
-There is a new language file corresponding to the new calendaring class
-which must be added to your language folder. Add the following item to
-your version: language/english/calendar_lang.php
-
-Step 5: Edit your config file
-=============================
-
-The original application/config/config.php file has a typo in it Open
-the file and look for the items related to cookies::
-
- $conf['cookie_prefix'] = "";
- $conf['cookie_domain'] = "";
- $conf['cookie_path'] = "/";
-
-Change the array name from $conf to $config, like this::
-
- $config['cookie_prefix'] = "";
- $config['cookie_domain'] = "";
- $config['cookie_path'] = "/";
-
-Lastly, add the following new item to the config file (and edit the
-option if needed)::
-
-
- /*
- |------------------------------------------------
- | URI PROTOCOL
- |------------------------------------------------
- |
- | This item determines which server global
- | should be used to retrieve the URI string. The
- | default setting of "auto" works for most servers.
- | If your links do not seem to work, try one of
- | the other delicious flavors:
- |
- | 'auto' Default - auto detects
- | 'path_info' Uses the PATH_INFO
- | 'query_string' Uses the QUERY_STRING
- */
-
- $config['uri_protocol'] = "auto";
-
