| <h1>Upgrading from 1.5.0 to 1.5.2</h1> |
| |
| <p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.5.0 or 1.5.1. 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>system/helpers/download_helper.php</dfn></li> |
| <li><dfn>system/helpers/form_helper.php</dfn></li> |
| <li><dfn>system/libraries/Table.php</dfn></li> |
| <li><dfn>system/libraries/User_agent.php</dfn></li> |
| <li><dfn>system/libraries/Exceptions.php</dfn></li> |
| <li><dfn>system/libraries/Input.php</dfn></li> |
| <li><dfn>system/libraries/Router.php</dfn></li> |
| <li><dfn>system/libraries/Loader.php</dfn></li> |
| <li><dfn>system/libraries/Image_lib.php</dfn></li> |
| <li><dfn>system/language/english/unit_test_lang.php</dfn></li> |
| <li><dfn>system/database/DB_active_rec.php</dfn></li> |
| <li><dfn> system/database/drivers/mysqli/mysqli_driver.php</dfn></li> |
| <li><dfn>codeigniter/</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 user guide</h2> |
| |
| <p>Please also replace your local copy of the user guide with the new version.</p> |
