A change in CodeIgniter 3.1.7 +moved this log message elsewhere and that naturally made the constructor +completely unnecessary. However, it was left in place to avoid immedate BC +breaks in a minor release. + +In version 3.2.0, that constructor is entirely removed, which would result +in fatal errors on attempts to call it. Particularly in code like this: +:: + + class Some_model extends CI_Model { + + public function __construct() + { + parent::__construct(); // calls CI_Model::__construct() + + do_some_other_thing(); + } + } + +All you need to do is remove that ``parent::__construct()`` call. On a side +note, the following seems to be a very common practice: +:: + + class Some_class extends CI_Something { + + public function __construct() + { + parent::__construct(); + } + } + +Please, do NOT do this! It's pointless; it serves no purpose and doesn't do +anything. If a parent class has a ``__construct()`` method, it will be +inherited by all its child classes and will execute just fine - you DON'T +have to explicitly call it unless you want to extend its logic. + +Step 4: Change database connection handling +=========================================== + +"Loading" a database, whether by using the *config/autoload.php* settings +or manually via calling ``$this->load->database()`` or the less-known +``DB()`` function, will now throw a ``RuntimeException`` in case of a +failure. + +In addition, being unable to set the configured character set is now also +considered a connection failure. + +.. note:: This has been the case for most database drivers in the in the + past as well (i.e. all but the 'mysql', 'mysqli' and 'postgre' + drivers). + +What this means is that if you're unable to connect to a database, or +have an erroneous character set configured, CodeIgniter will no longer +fail silently, but will throw an exception instead. + +You may choose to explicitly catch it (and for that purpose you can't use +*config/autoload.php* to load the :doc:`Database Class <../database/index>`) +:: + + try + { + $this->load->database(); + } + catch (RuntimeException $e) + { + // Handle the failure + } + +Or you may leave it to CodeIgniter's default exception handler, which would +log the error message and display an error screen if you're running in +development mode. + +Remove db_set_charset() calls +----------------------------- + +With the above-mentioned changes, the purpose of the ``db_set_charset()`` +method would now only be to change the connection character set at runtime. +That doesn't make sense and that's the reason why most database drivers +don't support it at all. +Thus, ``db_set_charset()`` is no longer necessary and is removed. + +Step 5: Check logic related to URI parsing of CLI requests +========================================================== + +When running a CodeIgniter application from the CLI, the +:doc:`URI Library <../libraries/uri>` will now ignore the +``$config['url_suffix']`` and ``$config['permitted_uri_chars']`` +configuration settings. + +These two options don't make sense under the command line (which is why +this change was made) and therefore you shouldn't be affected by this, but +if you've relied on them for some reason, you'd probably have to make some +changes to your code. + +Step 6: Check Cache Library configurations for Redis, Memcache(d) +================================================================= + +The new improvements for the 'redis' and 'memcached' drivers of the +:doc:`Cache Library <../libraries/caching>` may require some small +adjustments to your configuration values ... + +Redis +----- + +If you're using the 'redis' driver with a UNIX socket connection, you'll +have to move the socket path from ``$config['socket']`` to +``$config['host']`` instead. + +The ``$config['socket_type']`` option is also removed, although that won't +affect your application - it will be ignored and the connection type will +be determined by the format used for ``$config['host']`` instead. + +Memcache(d) +----------- + +The 'memcached' will now ignore configurations that don't specify a ``host`` +value (previously, it just set the host to the default '127.0.0.1'). + +Therefore, if you've added a configuration that only sets e.g. a ``port``, +you will now have to explicitly set the ``host`` to '127.0.0.1' as well. + +Step 7: Check usage of the Email library +======================================== + +The :doc:`Email Library <../libraries/email>` will now by default check the +validity of all e-mail addresses passed to it. This check used to be Off by +default, and required explicitly setting the **validate** option to ``TRUE`` +in order to enable it. + +Naturally, a validity check should not result in any problems, but this is +technically a backwards-compatibility break and you should check that +everything works fine. +If something indeed goes wrong with that, please report it as a bug to us, +and you can disable the **validate** option to revert to the old behavior. + +Step 8: Check usage of doctype() HTML helper +============================================ + +The :doc:`HTML Helper <../helpers/html_helper>` function +:php:func:`doctype()` used to default to 'xhtml1-strict' (XHTML 1.0 Strict) +when no document type was specified. That default value is now changed to +'html5', which obviously stands for the modern HTML 5 standard. + +Nothing should be really broken by this change, but if your application +relies on the default value, you should double-check it and either +explicitly set the desired format, or adapt your front-end to use proper +HTML 5 formatting. + +Step 9: Check usage of form_upload() Form helper +================================================ + +The :doc:`Form Helper <../helpers/form_helper>` function +:php:func:`form_upload()` used to have 3 parameters, the second of which +(``$value``) was never used, as it doesn't make sense for an HTML ``input`` +tag of the "file" type. + +That dead parameter is now removed, and so if you've used the third one +(``$extra``), having code like this:: + + form_upload('name', 'irrelevant value', $extra); + +You should change it to:: + + form_upload('name', $extra); + +Step 10: Remove usage of previously deprecated functionalities +============================================================= + +The following is a list of functionalities deprecated in previous +CodeIgniter versions that have been removed in 3.2.0: + +- ``$config['allow_get_array']`` (use ``$_GET = array();`` instead) +- ``$config['standardize_newlines']`` +- ``$config['rewrite_short_tags']`` (no impact;

It does so by creating a unique "row ID" based on -the product ID and any options associated with it. - -In nearly all cases, updating the cart will be something the user does -via the "view cart" page, so as a developer, it is unlikely that you -will ever have to concern yourself with the "row ID", other than making -sure your "view cart" page contains this information in a hidden form -field, and making sure it gets passed to the ``update()`` method when -the update form is submitted.
