In your controller, create a new action to handle autocomplete lookup queries, like so:


```php
<?php
//...Action public function actionAutoCompleteLookup() { if(Yii::app()->request->isAjaxRequest && isset($_GET['q'])) {     //* q is the default varGET variable name that is used by  // the autocomplete widget to pass in user input */
 
$name                = $_GET['q']; // this was set with the "max" attribute of the CAutoComplete widget $limit               = $_GET['limit']; $criteria            = new CDbCriteria; $criteria->condition = "name LIKE :sterm"; $criteria->params    = array(":sterm"=>"%$name%"); $criteria->limit     = $limit; $userArray           = User::model()->findAll($criteria); $returnVal           = '';
foreach($userArray as $userAccount)
{die();
}
    //...
 
    ?>
 
```
There are a few things to notice here:

<ol>
<li>A pipe "|" delimiter is used and natively recognized by jQuery to split a returned item into parts</li>
<li>Each autocomplete item is terminated by a newline character, or "\n"; note that the newline char must be enclosed in double quotes (") not single quotes(')</li>
