CodeIgniter User Guide Version 1.7

Upgrading from 1.6.3 to 1.6.4

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 these files and 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.

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 Session class page.

Step 3: Update your user guide

Please also replace your local copy of the user guide with the new version.
