i was just wondering if is there a different between this 2 things …







<?php echo CHtml::beginForm(); ?>

	

	<div class="row buttons">

		<?php echo CHtml::submitButton('Ipod',

		array(

		'ajax' => array(

		'type'=>'POST', //request type

		'url'=>"/yii_new/HelloWorld/index.php?r=HelloWorld/erg", //url to call

		'update'=>'#erg', 

		))

		

		); ?>

		

		 <?php echo CHtml::ajaxButton ("Update data",

          CController::createUrl('/HelloWorld/erg'), 

          array('update' => '#erg', 'type' => 'POST'));

 		?>


	</div>

	

<?php echo CHtml::endForm(); ?>

The only difference I see is that the previous is a submit button, and so is activated if a user press enter in a text-box, for example, and the latter no.

But actually they are nearly the same
