Ajax Validation for tabular or dynamic input

Hi everyone,

After taking much time for searching, I have a solution to ajax validation for tabular or dynamic input. It works for me. Hopefully it is helpful for someone. It is not a perfect but it gives you the concept how to implement this.

First,remember to enable ajaxValidation in the CActiveForm.

Next, Gennerate the inputs in the view, for example:

[VIEW]

<div class="row">
<?php for($i=1;$i<=5;$i++) { 
	$m = new AgentPostcode('reg'); //your model
?>
			<?php echo $form->textField($m,"[$i]postcode"); ?>
			<?php echo $form->error($m,"[$i]postcode"); ?>
<?php } ?>
</div>

In the contoller, rewrite the validate function which is copied and a bit modified from CActiveForm

	public static function validate($models, $dynamicModel, $attributes=null, $loadInput=true)
	{
		//copy from CActiveForm:validate
		$result=array();
		if(!is_array($models))
			$models=array($models);
			
		foreach($models as $model)
		{
			if($loadInput && isset($_POST[get_class($model)]))
				$model->attributes=$_POST[get_class($model)];
			$model->validate($attributes);
			foreach($model->getErrors() as $attribute=>$errors)
				$result[CHtml::activeId($model,$attribute)]=$errors;
		}
		//end copying

		//your own customization
		for($count=1;$count<=5;$count++)
		{
			$dynamicModel->clearErrors();
			
			if($loadInput && isset($_POST[get_class($dynamicModel)][$count]))
				$dynamicModel->attributes=$_POST[get_class($dynamicModel)][$count];
			$dynamicModel->validate($attributes);
			
			foreach($dynamicModel->getErrors() as $attribute=>$errors)
				$result[get_class($dynamicModel) . '_' . $count . '_' . $attribute]=$errors;
		} 

		return function_exists('json_encode') ? json_encode($result) : CJSON::encode($result);
	}

Finally, in the controller, modify ajax perform function:

	    // For Ajax Validation
	    if(isset($_POST['ajax']) && $_POST['ajax']==='agent-registeragent-form')
	    {
	    	$dynamicModel = new AgentPostcode('reg'); //your model
	        $validate = self::validate(array($model,$modelAC),$dynamicModel);
	        //$validate = CActiveForm::validate(array($model,$modelAC)); //original
 	        echo $validate;
	        Yii::app()->end();
	    }

That is all how to enable ajax validation for tabular or dynamic input.
Hope help someone.
