Question

I am trying to pass a variable from an ajaxLink into my controller but my controller is not getting the variable.

//view

$ids = Yii::app()->storedData->getIds();
    foreach($ids as $id) {
    echo 'ID '.$id .'<br />';

    echo CHtml::ajaxLink(   
     'remove',                                    
     array('/storedInfo/remove'), 
     array(
      'data' => array('removeItem' => $id),
    ));
    } 

//controller

public function actionRemove() {
        var_dump($_GET['removeItem']);  // RETURNS string(0) ""
        die();
    }

The ajax array you’re passing to CHtml::ajaxLink ends up taking the whole array and passing it to CJavaScript::encode().

As you mentioned in your comments, the $id you were using to build your data array was a PHP object. When this got to CJavaScript::encode, things got wonky, and the results weren’t what you were expecting. Extracting a string or numeric value from $id, rather that passing the whole object should take care of this, e.g.:

  'data' => array('removeItem' => $id->value) // obviously you'll need to use the proper key to get the value

Or maybe something like this depending on the data structure:

  'data' => array('removeItem' => settype($id, 'string'),
