| <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 CodeIgniter files</h2> |
| |
| <p>Replace these files and directories in your "system" folder with the new versions:</p> |
| |
| <ul> |
| |
| <li><dfn>application/config/user_agents.php</dfn> (new file for 1.5)</li> |
| <li><dfn>application/config/smileys.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 3: Update your config.php file</h2> |
| |
| <p>Open your <dfn>application/config/config.php</dfn> file and <kbd>ADD</kbd> these new items:</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://codeigniter.com/user_guide/general/core_classes.html |
| | http://codeigniter.com/user_guide/general/creating_libraries.html |
| | |
| */ |
| $config['subclass_prefix'] = 'MY_'; |
| |
| /* |
| |-------------------------------------------------------------------------- |
| | Rewrite PHP Short Tags |
| |-------------------------------------------------------------------------- |
| | |
| | If your PHP installation does not have short tag support enabled CI |
| | can rewrite the tags on-the-fly, enabling you to utilize that syntax |
| | in your view files. Options are TRUE or FALSE (boolean) |
| | |
| */ |
| $config['rewrite_short_tags'] = FALSE; |
| </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.</p> |
| |
| <p>If your <dfn>index.php</dfn> file has internal modifications, please add your modifications to the new file and use it.</p> |
| |
| |
| |
| <h2>Step 5: Update your user guide</h2> |
| |
| <p>Please also replace your local copy of the user guide with the new version.</p> |
