CodeIgniter User Guide Version 2.2.6

Upgrading from 1.7.1 to 1.7.2

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: Remove header() from 404 error template

If you are using header() in your 404 error template, such as the case with the default error_404.php template shown below, remove that line of code.

<?php header("HTTP/1.1 404 Not Found"); ?>

404 status headers are now properly handled in the show_404() method itself.

Step 3: Confirm your system_path

In your updated index.php file, confirm that the $system_path variable is set to your application's system folder.

Step 4: Update your user guide

Please replace your local copy of the user guide with the new version, including the image files.
