Starting with the blog tutorial, Yii developers are familiar with the notion of access rules defined in the controller, where the actions are allowed or denied depending on the user's name or role.

class CommentController extends CController {
    public function filters()
    {
        return array( 'accessControl' ); // perform access control for CRUD operations
    }

Some times the core validation rules provided by Yii won't satisfy all your needs, so you'll need to create your very own validation rule.

When you define or extend a class, you can create class variables and methods in Yii just like you can in any other PHP system:

class Comment extends CActiveRecord {
    public $helperVariable;
    public function rules() { ... }
    ...
}

$var   = $model->helperVariable;
$rules = $model->rules();

A common source of confusion among new Yii users is how the 'safe' validator works, how it works with other validators, and why it's necessary in the first place. This article means to clear up this confusion, as well as explain the notion of Massive Assignment.

<?php $this->widget('zii.widgets.grid.CGridView', array(

'dataProvider' => $dataprovider,
'id'=>'recipient_table',
    'selectionChanged'=>'updateEditForm',
'columns' => array(
	'rec_id',

Many applications wish to obtain parts of the URL for the current page (the hostname, the query string, etc.), and the CHttpRequest class wraps various $_SERVER variables to break down the URL into its constituent parts.

In this article, we describe the directory structure used by yiiframework.com - the official Yii framework website. While this structure may look overly complicated for small projects or may not be optimal in some sense, we believe it is appropriate for medium or large projects in a team development environment. In fact, we have successfully used the similar structure in some other big projects.

For some applications it can be advantageous for administration reasons to allow site administrators to login as other users. This is sometimes called user impersonation or "becoming that user".

This config is built on an Ubuntu 11.04 server. Software is nginx, php-fpm (php5-fpm). For performance, it's recommended to run php-fpm in SOCKET mode, instead of accessing via IP:PORT. That is the method shown below.
