If you want to trigger an ajax call on a Yii form element onchange, you can pass an array of ajax attributes as one of the “htmlOptions” like so:
<?php echo $form->textField($model,'my_input_field',array(
'ajax' => array(
'type'=>'POST', //request type
'url'=>$this->createUrl('site/ajaxAction'), // url to call controller action
'success'=>' function(data) { $(\'#my_output_field\').val(data) }',// function to call onsuccess
// "data" is returned data and function can be regular js or jQuery
// here we are are updating the value of another field that has id "my_output_field"
),
'size'=>60,
'maxlength'=>128,
)); ?>
and the (site) controller action would look something like:
public function actionAjaxAction() {
[check/filter inputs...]
[data functions...]
echo $my_val_string;
Yii::app()->end()
}
