Zend: get Url parameter from inside Zend_Form

Question

Zend talk.I need to set an hidden form field as the value of an url parameter. I have:

class Form_Custom extends Zend_Form
{
  public function init()
  {
   [..] 
   $id = new Zend_Form_Element_Hidden('name');
   [..]
  }
}

I know that I could pass it (from controller) inside an array of options while instantiating the class.But how could I tell the form to look for the URL parameter itself??

Thanks

Why not create the field in the form, and then set its value in controller, when the form is already instantiated? — mkilmanas, Jun 01 '11 at 11:49

class Form_Custom extends Zend_Form
{
  public function init()
  {
   //[..] 
   $id = new Zend_Form_Element_Hidden('name');
   //[..]
   $this->fill();
  }

  public function fill()
  {
      $this->name->setValue( Zend_Controller_Front::getInstance()->getRequest()->getParam( 'name', null ) );
  }
}

Using construction above you can populate your field when the form is created as well as manually using $form->fill() from controller

If you want to pass the URL value to your hidden field, you could use the following method:

In your controller:

    // Get wanted value from url
    $var = $this->_request->getParam('url');

    // Get correct form using Formloader helper (or any other method that you might be using)
    $this->view->form = $this->_helper->FormLoader('formname', array('url'=> $var);

And in your form you add the following:

protected $_url;

public function init(){
    $url = $this->_url;

    /*rest of your form*/
}

public function setUrl($value){
    $this->_url = $value;
}

That's it! Just pass the $url variable in your form the hidden field and you should be all done :)

I don't think there is a way to do that because Zend_form is dissociated from the controller. You could register in the registry your pos/get variables but thats dirty. You could also access directly $_GET/$_POST...

Or in your controller you can do:

$form = new Zend_form();
$form->populate($this->_getAllParams());

Which will populate your form with all values from $_POST/$_GET
