Hello All,

Is it possible to use more than two models in a [url="http://www.yiiframework.com/wiki/19/how-to-use-a-single-form-to-collect-data-for-two-or-more-models/"]multimodel[/url] form. If yes then why my third models data is not saving in its database?or is there any way to use it.

You can have as many models as you want but you are going to need to pull the data out of POST or GET and perform validation and saving.


<?php echo CHtml::errorSummary(array($a,$b,$c)); ?>


<div class="row">

    <?php echo $form->labelEx($a,'a_field'); ?>

    <?php echo $form->textField($a,'a_field'); ?>

    <?php echo $form->error($a,'a_field'); ?>

</div>


<div class="row">

    <?php echo $form->labelEx($b,'b_field'); ?>

    <?php echo $form->textField($b,'b_field'); ?>

    <?php echo $form->error($b,'b_field'); ?>

</div>


<div class="row">

    <?php echo $form->labelEx($c,'c_field'); ?>

    <?php echo $form->textField($c,'c_field'); ?>

    <?php echo $form->error($c,'c_field'); ?>

</div>


public function actionCreate()

{

	$a=new A;

	$b=new B;

	$c=new C;


	if(isset($_POST['A'], $_POST['B'], $_POST['B']))

	{

	    // populate input data to $a and $b

	    $a->attributes=$_POST['A'];

	    $b->attributes=$_POST['B'];

	    $c->attributes=$_POST['C'];


	    // validate BOTH $a, $b and $c

	    $valid=$a->validate();

	    $valid=$b->validate() && $valid;

			$valid=$c->validate() && $valid;


	    if($valid)

	    {

	        // use false parameter to disable validation

	        $a->save(false);

	        $b->save(false);

	        $c->save(false);

	        // ...redirect to another page

	    }

	}

	$this->render('create', array(

    'a'=>$a,

    'b'=>$b,

    'c'=>$c,

	));	

}

Please note that I just edited the code on the wiki page.
