Upgrading from 1.6.3 to 1.7.0 - In Development!

+ +

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 Validation Syntax

+ +

This is an optional, but recommended step, for people currently using the Validation class. CI 1.7 introduces a new Form Validation class, which +deprecates the old Validation library. We have left the old one in place so that existing applications that use it will not break, but you are encouraged to +migrate to the new version as soon as possible. Please read the user guide carefully as the new library works a little differently, and has several new features.

+ + + +

Step 4: Update your user guide

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