-<h1>Installation Instructions</h1>
-
-<p>CodeIgniter is installed in four steps:</p>
-
-<ol>
-<li>Unzip the package.</li>
-<li>Upload the CodeIgniter folders and files to your server. Normally the index.php file will be at your root.</li>
-<li>Open the <dfn>application/config/config.php</dfn> file with a text editor and set your base URL. If you intend to use encryption or sessions, set your encryption key.</li>
-<li>If you intend to use a database, open the <dfn>application/config/database.php</dfn> file with a text editor and set your database settings.</li>
-</ol>
-
-<p>If you wish to increase security by hiding the location of your CodeIgniter files you can rename the <dfn>system</dfn> and <dfn>application</dfn> folders
-to something more private. If you do rename them, you must open your main <kbd>index.php</kbd> file and set the <samp>$system_path</samp> and <samp>$application_folder</samp>
-variables at the top of the file with the new name you've chosen.</p>
-
-<p>For the best security, both the <dfn>system</dfn> and any <dfn>application</dfn> 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.</p>
-
-<p>If you would like to keep your views public it is also possible to move the <dfn>views</dfn> folder out of your application folder.</p>
-
-<p>After moving them, open your main <kdb>index.php</kbd> file and set the <samp>$system_path</samp>, <samp>$application_folder</samp> and <samp>$view_folder</samp> variables, preferably with a full path, e.g. '<dfn>/www/MyUser/system</dfn>'.</p>
-
-<p>
- 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 <kbd>ENVIRONMENT</kbd> constant, which is
- more fully described on the <a href="../general/security.html">security page</a>.
-</p>
-
-<p>That's it!</p>
-
-<p>If you're new to CodeIgniter, please read the <a href="../overview/getting_started.html">Getting Started</a> section of the User Guide to begin learning how
-to build dynamic PHP applications. Enjoy!</p>

-<h1>Troubleshooting</h1>
-
-<p>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 PATH_INFO variable needed to serve search-engine friendly URLs.
-
-As a first step, open your <dfn>application/config/config.php</dfn> file and look for the <kbd>URI Protocol</kbd>
-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 <kbd>application/config/config.php</kbd> file and change this:</p>
-
-<code>$config['index_page'] = "index.php";</code>
-
-<p>To this:</p>
-
-<code>$config['index_page'] = "index.php?";</code>

-<h1>Upgrading from 1.2 to 1.3</h1>
-
-<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.2. If you
-have not upgraded to that version please do so first.</p>
-
-
-<p>Before performing an update you should take your site offline by replacing the index.php file
-with a static one.</p>
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace the following directories in your "system" folder with the new versions:</p>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-<ul>
-<li>application/<strong>models</strong>/&nbsp;&nbsp; (new for 1.3)</li>
-<li>codeigniter&nbsp;&nbsp; (new for 1.3)</li>
-<li>drivers</li>
-<li>helpers</li>
-<li>init</li>
-<li>language</li>
-<li>libraries</li>
-<li>plugins</li>
-<li>scaffolding</li>
-</ul>
-
-
-<h2>Step 2: Update your error files</h2>
-
-<p>Version 1.3 contains two new error templates located in <dfn>application/errors</dfn>, and for naming consistency the other error templates have
-been renamed.</p>
-
-<p>If you <strong>have not</strong> customized any of the error templates simply
-replace this folder:</p>
-
-<ul>
-<li>application/errors/</li>
-</ul>
-
-<p>If you <strong>have</strong> customized your error templates, rename them as follows:</p>
-
-
-<ul>
-<li>404.php&nbsp;&nbsp; =&nbsp; error_404.php</li>
-<li>error.php&nbsp;&nbsp; =&nbsp; error_general.php</li>
-<li>error_db.php&nbsp;&nbsp; (new)</li>
-<li>error_php.php&nbsp;&nbsp; (new)</li>
-</ul>
-
-
-<h2>Step 3: Update your index.php file</h2>
-
-<p>Please open your main <dfn>index.php</dfn> file (located at your root). At the very bottom of the file, change this:</p>
-
-<code>require_once BASEPATH.'libraries/Front_controller'.EXT;</code>
-
-<p>To this:</p>
-
-<code>require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;</code>
-
-
-<h2>Step 4: Update your config.php file</h2>
-
-<p>Open your <dfn>application/config/config.php</dfn> file and add these new items:</p>
-
-<pre>
-/*
-|------------------------------------------------
-| 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';
-</pre>
-
-
-<h2>Step 5: Update your database.php file</h2>
-
-<p>Open your <dfn>application/config/database.php</dfn> file and add these new items:</p>
-
-<pre>
-$db['default']['dbprefix'] = "";
-$db['default']['active_r'] = TRUE;
-</pre>
-
-
-<h2>Step 6: Update your user guide</h2>
-
-<p>Please also replace your local copy of the user guide with the new version.</p>

-

-
-<p>As of version 1.3.3, CodeIgniter does <strong>not</strong> 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,
-<a href="../general/models.html">as described here</a>.</p>

-<h2>Step 5: Update your user guide</h2>
-<p>Please also replace your local copy of the user guide with the new version.</p>

-<h1>Upgrading from 1.6.3 to 1.7.0</h1>
-
-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
-
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace these files and directories in your "system" folder with the new versions:</p>
-
-<ul>
-
-<li><dfn>system/codeigniter</dfn></li>
-<li><dfn>system/database</dfn></li>
-<li><dfn>system/helpers</dfn></li>
-<li><dfn>system/language</dfn></li>
-<li><dfn>system/libraries</dfn></li>
-</ul>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-
-<h2>Step 2: Update your Session Table</h2>
-
-<p>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 <dfn>user_data</dfn> to your session table.
-Here is an example of what this column might look like for MySQL:</p>
-
-<code>user_data text NOT NULL</code>
-
-<p>To add this column you will run a query similar to this:</p>
-
-<code>ALTER TABLE `ci_sessions` ADD `user_data` text NOT NULL</code>
-
-<p>You'll find more information regarding the new Session functionality in the <a href="../libraries/sessions.html">Session class</a> page.</p>
-
-
-<h2>Step 3: Update your Validation Syntax</h2>
-
-<p>This is an <strong>optional</strong>, but recommended step, for people currently using the Validation class. CI 1.7 introduces a new <a href="../libraries/form_validation.html">Form Validation class</a>, 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.</p>
-
-
-
-<h2>Step 4: Update your user guide</h2>
-<p>Please replace your local copy of the user guide with the new version, including the image files.</p>

-

-<p>In your updated index.php file, confirm that the <dfn>$system_path</dfn> variable is set to your application's system folder.</p>
-
-<h2>Step 4: Update your user guide</h2>
-<p>Please replace your local copy of the user guide with the new version, including the image files.</p>

-<h1>Upgrading from 1.7.2 to 2.0.0</h1>
-
-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
-
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace all files and directories in your "system" folder <strong>except</strong> your <kbd>application</kbd> folder.</p>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-<h2>Step 2: Adjust get_dir_file_info() where necessary</h2>
-
-<p>Version 2.0.0 brings a non-backwards compatible change to <kbd>get_dir_file_info()</kbd> in the <a href="../helpers/file_helper.html">File Helper</a>. 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 <em>need</em>
- recursiveness where you are using this helper function, change such instances, setting the second parameter, <kbd>$top_level_only</kbd> to FALSE:</p>
-
-<code>get_dir_file_info('/path/to/directory', <kbd>FALSE</kbd>);</code>
-
-</p>
-
-<h2>Step 3: Convert your Plugins to Helpers</h2>
-
-<p>2.0.0 gets rid of the "Plugin" system as their functionality was identical to Helpers, but non-extensible. You will need to rename your plugin files from <var>filename_pi.php</var> to <var>filename_helper.php</var>, move them to your <kbd>helpers</kbd> folder, and change all instances of:
-
- <code>$this->load->plugin('foo');</code>
-
-to
-
- <code>$this->load->helper('foo');</code>
-
-</p>
-
-<h2>Step 4: Update stored encrypted data</h2>
-
-<p class="important"><strong>Note:</strong> If your application does not use the Encryption library, does not store Encrypted data permanently, or is on an environment that does not support Mcrypt, you may skip this step.</p>
-
-<p>The Encryption 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, <kbd>encode_from_legacy()</kbd> 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.</p>
-
-<p>Please read <a href="../libraries/encryption.html#legacy">how to use this method</a> in the Encryption library documentation.</p>
-
-<h2>Step 5: Remove loading calls for the compatibility helper.</h2>
-<p>The compatibility helper has been removed from the CodeIgniter core. All methods in it should be natively available in supported PHP versions.</p>
-
-<h2>Step 6: Update Class extension</h2>
-<p>All core classes are now prefixed with <kbd>CI_</kbd>. Update Models and Controllers to extend CI_Model and CI_Controller, respectively.</p>
-
-<h2>Step 7: Update Parent Constructor calls</h2>
-<p>All native CodeIgniter classes now use the PHP 5 <kbd>__construct()</kbd> convention. Please update extended libraries to call <kbd>parent::__construct()</kbd>.</p>
-
-<h2>Step 8: Update your user guide</h2>
-<p>Please replace your local copy of the user guide with the new version, including the image files.</p>

- The default behavior for <kbd>form_open()</kbd> 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:
-</p>
-
-<code>echo form_open(); //&lt;form action="" method="post" accept-charset="utf-8"></code>
-
-<p>to use either a / or <kbd>base_url()</kbd>:</p>

-
-<p>If you are running a stock <dfn>index.php</dfn> file simply replace your version with the new one.</p>
-
-<p>If your <dfn>index.php</dfn> file has internal modifications, please add your modifications to the new file and use it.</p>
-
-<h2>Step 3: Replace config/user_agents.php</h2>
-
-<p>This config file has been updated to contain more user agent types, please copy it to <kbd>application/config/user_agents.php</kbd>.</p>
-
-<h2>Step 4: Change references of the EXT constant to ".php"</h2>
-<p class="important"><strong>Note:</strong> 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.</p>
-
-<h2>Step 5: Remove APPPATH.'third_party' from autoload.php</h2>
-
-<p>Open application/config/autoload.php, and look for the following:</p>
-
-<code>$autoload['packages'] = array(APPPATH.'third_party');</code>
-
-<p>If you have not chosen to load any additional packages, that line can be changed to:</p>
-<code>$autoload['packages'] = array();</code>
-
-<p>Which should provide for nominal performance gains if not autoloading packages.</p>
-
-<h2>Update Sessions Database Tables</h2>
-
-<p>If you are using database sessions with the CI Session Library, please update your <samp>ci_sessions</samp> database table as follows:</p>
-
-<code>
- CREATE INDEX last_activity_idx ON ci_sessions(last_activity);
- ALTER TABLE ci_sessions MODIFY user_agent VARCHAR(120);

-
-<p>This config file has been updated to contain more user agent types, please copy it to <kbd>application/config/user_agents.php</kbd>.</p>

-<h1>Upgrading From Beta 1.0 to Beta 1.1</h1>
-
-<p>To upgrade to Beta 1.1 please perform the following steps:</p>
-
-<h2>Step 1: Replace your index file</h2>
-
-<p>Replace your main <kbd>index.php</kbd> 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.</p>
-
-<h2>Step 2: Relocate your config folder</h2>
-
-<p>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 <kbd>config</kbd> directory must now reside
-inside of your <dfn>application</dfn> folder, so please move it there.</p>
-
-
-<h2>Step 3: Replace directories</h2>
-
-<p>Replace the following directories with the new versions:</p>
-
-<ul>
-<li>drivers</li>
-<li>helpers</li>
-<li>init</li>
-<li>libraries</li>
-<li>scaffolding</li>
-</ul>
-
-
-<h2>Step 4: Add the calendar language file</h2>
-
-<p>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: <dfn>language/english/calendar_lang.php</dfn></p>
-
-
-<h2>Step 5: Edit your config file</h2>
-
-<p>The original <kbd>application/config/config.php</kbd> file has a typo in it Open the file and look for the items related to cookies:</p>
-
-<code>$conf['cookie_prefix'] = "";<br />
-$conf['cookie_domain'] = "";<br />
-$conf['cookie_path'] = "/";</code>
-
-<p>Change the array name from <kbd>$conf</kbd> to <kbd>$config</kbd>, like this:</p>
-
-<code>$config['cookie_prefix'] = "";<br />
-$config['cookie_domain'] = "";<br />
-$config['cookie_path'] = "/";</code>
-
-<p>Lastly, add the following new item to the config file (and edit the option if needed):</p>
-
-<code><br />
-/*<br />
-|------------------------------------------------<br />
-| URI PROTOCOL<br />
-|------------------------------------------------<br />
-|<br />
-| This item determines which server global <br />
-| should be used to retrieve the URI string. The <br />
-| default setting of "auto" works for most servers.<br />
-| If your links do not seem to work, try one of <br />
-| the other delicious flavors:<br />
-| <br />
-| 'auto' Default - auto detects<br />
-| 'path_info' Uses the PATH_INFO <br />
-| 'query_string' Uses the QUERY_STRING<br />
-*/<br />
-<br />
-$config['uri_protocol'] = "auto";</code>
