Yii CForm, Ajax Validation Nested Forms

Question

I created the following array of nested forms:

return array( 'elements' => array( 'contact' => array( 'type' => 'form', 'elements' => array( 'first_name' => array( 'type' => 'text', ), 'last_name' => array( 'type' => 'text', ) ), ), 'lead' => array( 'type' => 'form', 'elements' => array( 'primary_skills' => array( 'type' => 'textarea', ), ), ), ), 'buttons' => array( 'save-lead' => array( 'type' => 'submit', 'label' => 'Create', 'class' => 'btn' ), ) ); 

I have a watch page like this

 echo $form->renderBegin(); echo $form['lead']; echo $form['contact']; echo $form->buttons['save-lead']; echo $form->renderEnd(); 

my actionCreate is like this

 $form = new CForm('application.views.leads.register'); $form['lead']->model = new Lead; $form['contact']->model = new Contact; // how can i perform ajax validation only for $form['contact'] $this->performAjaxValidation($model); //if contact form save btn is clicked if ($form->submitted('save-lead') && $form['contact']->validate() && $form['lead']->validate() ) { $contact = $form['contact']->model; $lead = $form['lead']->model; if ($contact->save()) { $lead->contact_id = $contact->id; if ($lead->save()) { $this->redirect(array('leads/view', 'id' => $lead->id)); } } } 

Ajax validation method

 protected function performAjaxValidation($model) { if (isset($_POST['ajax']) && $_POST['ajax'] === 'contact') { echo CActiveForm::validate($model); Yii::app()->end(); } } 

so my question is how can I do ajax check on $ form ['contact'] and $ form ['lead'] elements separately?

Answer 1

There may be several forms on a page, but they should not be nested. Nested forms are invalid.

You have to do your own check

you must add to your controller’s actionCreate and actionUpdate (I have the main Invoice model and the secondary InvoiceDetails model, and there may be more than one form for InvoiceDetails). But, of course, forms cannot be nested!

  public function actionCreate() { ... $PostVar = 'Invoices'; if (Yii::app()->request->isAjaxRequest) { // if ajax $this->performAjaxValidation($model, strtolower($PostVar) . '-form'); $PostVar = ucfirst($PostVar); if (isset($_POST[$PostVar])) { $model->attributes = $_POST[$PostVar]; $dynamicModel = new InvoiceDetails(); //your model $valid = self::validate($model, $dynamicModel); if (!isset($_POST['ajax'])) { if (isset($_POST['InvoiceDetails'])) { $allDetails = array(); $allDynamicModels = $_POST['InvoiceDetails']; //your own customization foreach ($allDynamicModels as $key => $value) { $InvDet = InvoiceDetails::model()->findByPk($_POST['InvoiceDetails'][$key]['id']); if (!isset($InvDet)) { $InvDet = new InvoiceDetails(); } $InvDet->attributes = $_POST['InvoiceDetails'][$key]; $InvDet->save(); $allDetails[] = $InvDet; } } $model->invoicedetails = $allDetails; if ($model->save()) { echo CJSON::encode(array('status' => 'success')); Yii::app()->end(); } else { echo CJSON::encode(array('status' => 'error saving')); Yii::app()->end(); } } // Here we say if valid if (!isset($valid)) { echo CJSON::encode(array('status' => 'success')); } else { echo $valid; } Yii::app()->end(); } else { $this->renderPartial('_form', ...); } } else { // not AJAX request $this->render('_form', ...)); }

Nested forms are invalid. You can use scenarios to validate the form in different instances.

Example:

 `if ($form->submitted('save-lead'){ $form->scenario = 'save-lead'; if($form->validate()) { $form->save(); } } else { $form->scenario = 'contact'; if($form->validate()){ $form->save(); } } $this->render('_form', array('form'=>$form);`
