Zend Form ViewScript Not Working

[Erik Olof Wahlstrom]

I have read through the forums and tried for several hours now to get a simple viewscript to work - I am still unable to get a form element to render. Hopefully someone can offer some advice:

My Controller:
<?php
class Orders_OrderdetailController extends Zend_Controller_Action{
  public function preDispatch(){
    $this->_helper->layout->disableLayout();
  }
  public function indexAction(){
    ...    
    $form = new OrderDetailForm();
    $form->populate($orderData[0]);
    $this->view->form = $form;
    ...
  }
}

class OrderDetailForm extends Zend_Form{
  public function init(){
    $this->addElement('text', 'ORDER_NUMBER', array(
      'label' => 'Order Number'
    ));
    //$ORDER_NUMBER = new Zend_Form_Element_Text('ORDER_NUMBER');
    //$ORDER_NUMBER->setLabel('Order Number');
    //$this->addElement($ORDER_NUMBER);
    $this->setDecorators(array(array('viewScript', array('viewScript' => 'orderdetail/orderdetailform.phtml'))));
  }
}

_____________________________________________________________________________
My index.phtml view script:

Test View Order

<?php echo $this->form; ?>

_____________________________________________________________________________
My orderdetailform.phtml view script:
<?php
    foreach ($this->element as $item) {
        $item->setView($this);
        echo "Setting View<br>";
    }
?>
<form>
       

Order Detail Form

        <?php echo $this->ORDER_NUMBER; ?>
</form>

__________________________________________________________________

Can a skilled eye see what's wrong - I have tried so many variations of this and have yet to see a text input element render...

Thanks in advance!

Don't have time to go through this in detail, but try to replace:

$this->setDecorators(array(array('viewScript', array('viewScript' => 'orderdetail/orderdetailform.phtml'))))

with

$this->setDecorators(array(array('ViewScript', array('viewScript' => 'orderdetail/orderdetailform.phtml'))))

Note that the first occurance of ViewScript has a capitl V.

Do you get any errors when you try to run your code?

[Erik Olof Wahlstrom]

Tried your suggestion - this seems to give the same result.  No errors - the

Order Detail Form

 found in the orderdetailform.phtml is rendered on the page - just no form elements...

I didn't notice your view script is for the Form itself and not for the form element.

In your view script try calling:

<?php echo $this->getElement('ORDER_NUMBER')->render();?>

render() takes an optional object that implement Zend_View_Interface as a parameter.

Change the above to "$this->element->ORDER_NUMBER". The form is in the
view script as the "element" property, and you want to grab the element
ORDER_NUMBER off the form object. (You're already doing that in the
foreach loop at the top of the view script ;-))

Thanks Matthew - your suggestion works.  One of my sources was the article you wrote at http://devzone.zend.com/article/3450-Decorators-with-Zend_Form and I was trying to implement the ViewScript as you had it in that article:

Like so:

Please register with us!

<form action="<?= $this->escape($this->form->getAction() ?>"
      method="<?= $this->escape($this->form->getMethod() ?>">

<fieldset>
    <legend>Demographics</legend>
    <p>
        Please provide us the following information so we can know more about
        you.
    </p>

    <?= $this->form->age ?>
    <?= $this->form->nationality ?>
    <?= $this->form->income ?>
</fieldset>

but within the specified viewscript doesn't $this->form become merely $this?  Since in the controller I am passing $this->view->form = $form - I was assuming that what you had above ($this->form->age) would turn in to $this->age... I guess I'm a little confused on the scope of some of these things...
