Upgrading from 3.0.5 to 3.0.6¶

+

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: Update your index.php file (optional)¶

+

We’ve made some tweaks to the index.php file, mostly related to proper +usage of directory separators (i.e. use the DIRECTORY_SEPARATOR +constant instead of a hard coded forward slash “/”).

+

Nothing will break if you skip this step, but if you’re running Windows +or just want to be up to date with every change - we do recommend that +you update your index.php file.

+

Tip: Just copy the ``ENVIRONMENT``, ``$system_path``, ``$application_folder`` +and ``$view_folder`` declarations from the old file and put them into the +new one, replacing the defaults.

+

Step 3: Remove ‘prep_for_form’ usage (deprecation)¶

+

The Form Validation Library 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, 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.
