1. PersonForm model
2. person_form.php
3. PersonController.php

hi guys, Here I'm going to give you a working example of ajax form submiting in Yii.

You can try a simple demo here:DEMO

Find the source code @https://github.com/sirinibin/yiidemos

PersonForm model ¶

<?php

class PersonForm extends CFormModel
{

 	public $name;
        public $age;

	/**
	 * Declares the validation rules.
	 * title is required
	 */
	public function rules()
	{
		return array(
			
		       );
	}

	/**
	 * Declares attribute labels.
	 */
	public function attributeLabels()
	{
		return array(
			'name'=>'Name',
                        'age'=>'Age',
		);
	}
 
}

?>

form:

person_form.php ¶

<div class="form">

<?php $form=$this->beginWidget('CActiveForm', array(
	'id'=>'person-form-edit_person-form',
	'enableAjaxValidation'=>false,
        'htmlOptions'=>array(
                               'onsubmit'=>"return false;",/* Disable normal form submit */
                               'onkeypress'=>" if(event.keyCode == 13){ send(); } " /* Do ajax call when user presses enter key */
                             ),
)); ?>

	
	<?php echo $form->errorSummary($model); ?>

	<div class="row">
		<?php echo $form->labelEx($model,'name'); ?>
		<?php echo $form->textField($model,'name'); ?>
		<?php echo $form->error($model,'name'); ?>
	</div>
        <div class="row">
		<?php echo $form->labelEx($model,'age'); ?>
		<?php echo $form->textField($model,'age'); ?>
		<?php echo $form->error($model,'age'); ?>
	</div>


	<div class="row buttons">
	    <?php echo CHtml::Button('SUBMIT',array('onclick'=>'send();')); ?> 
	</div>

<?php $this->endWidget(); ?>

</div><!-- form -->
<script type="text/javascript">

function send()
 {
   
   var data=$("#person-form-edit_person-form").serialize();


  $.ajax({
   type: 'POST',
    url: '<?php echo Yii::app()->createAbsoluteUrl("person/ajax"); ?>',
   data:data,
success:function(data){
                alert(data); 
              },
   error: function(data) { // if error occured
         alert("Error occured.please try again");
         alert(data);
    },

  dataType:'html'
  });

}

</script>

Controller:

PersonController.php ¶

class PersonController extends CController
{
 public function actionAjax()
 {
    $model=new PersonForm;

    // uncomment the following code to enable ajax-based validation
    /*
    if(isset($_POST['ajax']) && $_POST['ajax']==='person-form-edit_person-form')
    {
        echo CActiveForm::validate($model);
        Yii::app()->end();
    }
    */


    if(isset($_POST['PersonForm']))
    {
       
          
        $model->attributes=$_POST['PersonForm'];
        if($model->validate())
        {
           // form inputs are valid, do something here
           print_r($_REQUEST);
           return;
                    
        
         
        }
    }
    $this->render('person_form',array('model'=>$model));

 }

In the above example you will get an alert on the javascript ajax callback function which will be a server response from the controller action.You can customise this code as per your needs.i hope this will help someone.Thanks
