Non-backwards compatible changes are extremely rare - in CodeIgniter, but this one we feel was warranted due to how easy it was to create serious server performance issues. If you <em>need</em> - recursiveness where you are using this helper function, change such instances, setting the second parameter, <kbd>$top_level_only</kbd> to FALSE:</p> - -<code>get_dir_file_info('/path/to/directory', <kbd>FALSE</kbd>);</code> - -</p> - -<h2>Step 3: Convert your Plugins to Helpers</h2> - -<p>2.0.0 gets rid of the "Plugin" system as their functionality was identical to Helpers, but non-extensible. You will need to rename your plugin files from <var>filename_pi.php</var> to <var>filename_helper.php</var>, move them to your <kbd>helpers</kbd> folder, and change all instances of: - - <code>$this->load->plugin('foo');</code> - -to - - <code>$this->load->helper('foo');</code> - -</p> - -<h2>Step 4: Update stored encrypted data</h2> - -<p class="important"><strong>Note:</strong> If your application does not use the Encryption library, does not store Encrypted data permanently, or is on an environment that does not support Mcrypt, you may skip this step.</p> - -<p>The Encryption library has had a number of improvements, some for encryption strength and some for performance, that has an unavoidable consequence of - making it no longer possible to decode encrypted data produced by the original version of this library. To help with the transition, a new method has - been added, <kbd>encode_from_legacy()</kbd> that will decode the data with the original algorithm and return a re-encoded string using the improved methods. - This will enable you to easily replace stale encrypted data with fresh in your applications, either on the fly or en masse.</p> - -<p>Please read <a href="../libraries/encryption.html#legacy">how to use this method</a> in the Encryption library documentation.</p> - -<h2>Step 5: Remove loading calls for the compatibility helper.</h2> -<p>The compatibility helper has been removed from the CodeIgniter core. All methods in it should be natively available in supported PHP versions.</p> - -<h2>Step 6: Update Class extension</h2> -<p>All core classes are now prefixed with <kbd>CI_</kbd>. Update Models and Controllers to extend CI_Model and CI_Controller, respectively.</p> - -<h2>Step 7: Update Parent Constructor calls</h2> -<p>All native CodeIgniter classes now use the PHP 5 <kbd>__construct()</kbd> convention. Please update extended libraries to call <kbd>parent::__construct()</kbd>.</p> - -<h2>Step 8: Update your user guide</h2> -<p>Please replace your local copy of the user guide with the new version, including the image files.</p> - -</div> -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="index.html">Installation Instructions</a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="troubleshooting.html">Troubleshooting</a> -</p> -<p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2011 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> -</div> - -</body> -</html>
