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:
- 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 Session class page.
Step 3: Update your user guide
Please also replace your local copy of the user guide with the new version.
