| <h1>Upgrading from 1.4.1 to 1.5.0</h1> | |
| <p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.4.1. If you | |
| have not upgraded to that version please do so first.</p> | |
| <p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p> | |
| <h2>Step 1: Update your Code Igniter files</h2> | |
| <p>Replace these files and directories in your "system" folder with the new versions: | |
| <ul> | |
| <li><dfn>application/config/user_agents.php</dfn> (new file for 1.5)</li> | |
| <li><dfn>codeigniter/</dfn></li> | |
| <li><dfn>database/</dfn> (new folder for 1.5. Replaces the "drivers" folder)</li> | |
| <li><dfn>helpers/</dfn></li> | |
| <li><dfn>language/</dfn></li> | |
| <li><dfn>libraries/</dfn></li> | |
| <li><dfn>scaffolding/</dfn></li> | |
| </ul> | |
| <p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p> | |
| <h2>Step 2: Update your database.php file</h2> | |
| <p>Open your <dfn>application/config/database.php</dfn> file and add these new items:</p> | |
| <pre> | |
| $db['default']['cache_on'] = FALSE; | |
| $db['default']['cachedir'] = ''; | |
| </pre> | |
| <h2>Step 2: Update your config.php file</h2> | |
| <p>Open your <dfn>application/config/config.php</dfn> file and <kbd>ADD</kbd> this new item:</p> | |
| <pre> | |
| /* | |
| |-------------------------------------------------------------------------- | |
| | Class Extension Prefix | |
| |-------------------------------------------------------------------------- | |
| | | |
| | This item allows you to set the filename/classname prefix when extending | |
| | native libraries. For more information please see the user guide: | |
| | | |
| | http://www.codeigniter.com/user_guide/general/core_classes.html | |
| | http://www.codeigniter.com/user_guide/general/creating_libraries.html | |
| | | |
| */ | |
| $config['subclass_prefix'] = 'MY_'; | |
| </pre> | |
| <p>In that same file <kbd>REMOVE</kbd> this item:</p> | |
| <pre> | |
| /* | |
| |-------------------------------------------------------------------------- | |
| | Enable/Disable Error Logging | |
| |-------------------------------------------------------------------------- | |
| | | |
| | If you would like errors or debug messages logged set this variable to | |
| | TRUE (boolean). Note: You must set the file permissions on the "logs" folder | |
| | such that it is writable. | |
| | | |
| */ | |
| $config['log_errors'] = FALSE; | |
| </pre> | |
| <p>Error logging is now disabled simply by setting the threshold to zero.</p> | |
| <h2>Step 4: Update your main index.php file</h2> | |
| <p>If you are running a stock <dfn>index.php</dfn> file simply replace your version with the new one. If you are running one with | |
| internal modifications, open it and add this line of code near the bottom:</p> | |
| <code>define('FCPATH', __FILE__);</code> | |
| <h2>Step 5: Update your user guide</h2> | |
| <p>Please also replace your local copy of the user guide with the new version.</p> | |
