Problem retrieving values from Zend_Form_SubForms - no values returned

I have a Zend_Form that has 4 or more subforms.

/** Code Snippet **/ $bigForm = new Zend_Form();

    $littleForm1 = new Form_LittleForm1();
    $littleForm1->setMethod('post');

    $littleForm2 = new Form_LittleForm2();
    $littleForm2->setMethod('post');

    $bigForm->addSubForm($littleForm1,'littleForm1',0);
    $bigForm->addSubForm($littleForm2,'littleForm2',0);

On clicking the 'submit' button, I'm trying to print out the values entered into the forms, like so:

/** Code snippet, currently not validating, just printing **/

if($this->_request->getPost()){ $formData = array();

  foreach($bigForm->getSubForms() as $subForm){
        $formData = array_merge($formData, $subForm->getValues());      
  }
  /* Testing */
  echo "<pre>";
  print_r($formData);
  echo "</pre>";

}

The end result is that - all the elements in the form do get printed, but the values entered before posting the form don't get printed.

Any thoughts are appreciate开发者_开发问答d...I have run around circles working on this!

Thanks in advance!

This is what I did -

$bigForm->addElements($littleForm1->getElements());

Then, iterated over the form elements like so:

    $displayGroup1 = array();

    foreach($bigForm->getElements() as $name=>$value){

        array_push($displayGroup1, $name);
    }

Then, add a displayGroup to $bigForm:

   $bigForm->addDisplayGroup($displayGroup1, 'test',array('legend'=>'Test'));

And repeat for multiple display groups.

I'm sure there is a better way to do it, but I'm currently unable to find one out. This is currently one way I can think of to retrieve all the form values via $_POST, if a form is made up of one or more subforms. If any one knows of a better solution, please post it!

A Zend_Form does not automatically retrieve values from the $_POST variable. Use:

$bigform->populate($_POST)

Or alternatively:

$bigform->populate($this->_request->getPost())

Another thing to keep in mind is that if the sub forms contain elements with the same name they will clash. To check this use the option View => Page Source in your browser and look at the HTML that is generated. When you see two <input> elements with the same name attribute, then this is the problem.

The Zend solution for this is to give the sub form elements different names using setElementsBelongTo:

$littleForm1->setElementsBelongTo('littleForm1');
$littleForm2->setElementsBelongTo('littleForm2');

Furthermore you should leave out these calls as they serve no purpose (but you should set them for the $bigForm):

$littleForm->setMethod('post');
