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 :doc:`Session class <../libraries/sessions>` 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 :doc:`Form Validation +class <../libraries/form_validation>`, 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. |
