Best Ways to Use Zend_Form in Zend MVC

Question

When using Zend_Form, I find that I create many controller methods that look like this:

function editPersonAction()
{
   $model = $this->getPersonModel();
   $form = $this->getPersonEditForm();
   if ($this->getRequest()->isPost() {
       $data = $this->getRequest()->getPost();
       //$form->populate($data); [removed in edit]

       if ($form->isValid($data)) {
           $data = $form->getValues();
           $model->setFromArray($data);
           // code to save model then decide which page to redirect to
       }
   } else {
       $form->populate($model->toArray());
   }
   $this->view->form = $form;
}

Most of this code is always the same, and I'm sure there are better ways to do this. What other templates are used by people with Zend_Form to reduce the amount of template used?

Answer 1

I like to keep as much as possible in models

function editPersonAction()
{
   $model = $this->getPersonModel();

   if ($this->getRequest()->isPost() {
       $data = $this->getRequest()->getPost();

       if ($model->validateForm($data)) {
           // code to save model then decide which page to redirect to
       } else {
          // error management
       } 
   } 

   $this->view->form = $model->getForm();
}

So then in the model I would:

public function validateForm(array $data)
{    
    $form = $this->getForm();

    if($form->isValid($data))
    {
        // code to save model state

        return true;
    } else {
        return false;
    }
}

public function getForm($instance = 'default') {
   if (!isset($this->_forms[$instance])) {
       $this->_forms[$instance] = new Your_Form_Class();           
       $this->_forms[$instance]->populate($this->toArray());
   }

   return $this->_forms[$instance];
}

In addition, you can add these methods to an abstract model in which all your application models will be distributed, and then only overwrite them when you need to do something special.

$form- > populate()? IIRC .

, . , , , . , (, getPersonEditForm . , , :

function editPersonAction()
{
   $model = $this->getPersonModel();
   $form  = $this->getPersonEditForm();

   if($this->getRequest()->isPost()) 
   {
       if($model->setFromArray($this->getRequest()->getPost()))
       {
           // code to decide which page to redirect to
       }
   }
   else
   {
       $form->populate($model->toArray());
   }

   $this->view->form = $form;
}

, setFromArray :

public function setFromArray(array $data)
{
    $form = $this->getRegistrationForm();

    if($form->isValid($data))
    {
        // code to save model state

        return true;
    }
    else
    {
        return false;
    }
}
