How to print a group display individually from its content?

问题

I'm using Zend Framework and Zend_Form to render my form. But as I found it hard to customize it, I decided to print elements individually.

Problem is, I don't know how to print individual elements inside a display group. I know how to print my display groups (fieldsets) but I need to add something inside it (like a <div class="spacer"></div> to cancel the float:left.

Is there any way to display the group only without its content so I can print them individually myself?

Thank you for your help.

What you are looking for is the 'ViewScript' decorator. It allows you to form your html in any way you need. Here is a simple example of how it works:

The form, a simple search form:

<?php
class Application_Form_Search extends Zend_Form
{
    public function init() {
        // create new element
        $query = $this->createElement('text', 'query');
        // element options
        $query->setLabel('Search Keywords');
        $query->setAttribs(array('placeholder' => 'Query String',
            'size' => 27,
            ));
        // add the element to the form
        $this->addElement($query);
        //build submit button
        $submit = $this->createElement('submit', 'search');
        $submit->setLabel('Search Site');
        $this->addElement($submit);
    }
}

Next is the 'partial' this is the decorator, here is where you build the html how you want it:

<article class="search">
<!-- I get the action and method from the form but they were added in the controller -->
    <form action="<?php echo $this->element->getAction() ?>"
          method="<?php echo $this->element->getMethod() ?>">
        <table>
            <tr>
            <!-- renderLabel() renders the Label decorator for the element
                <th><?php echo $this->element->query->renderLabel() ?></th>
            </tr>
            <tr>
            <!-- renderViewHelper() renders the actual input element, all decorators can be accessed this way -->
                <td><?php echo $this->element->query->renderViewHelper() ?></td>
            </tr>
            <tr>
            <!-- this line renders the submit element as a whole -->
                <td><?php echo $this->element->search ?></td>
            </tr>
        </table> 
    </form>
</article>

and finally the controller code:

public function preDispatch() {
        //I put this in the preDispatch method because I use it for every action and have it assigned to a placeholder.
        //initiate form
        $searchForm = new Application_Form_Search();
        //set form action
        $searchForm->setAction('/index/display');
        //set label for submit button
        $searchForm->search->setLabel('Search Collection');
        //I add the decorator partial here. The partial .phtml lives under /views/scripts
        $searchForm->setDecorators(array(
            array('ViewScript', array(
                    'viewScript' => '_searchForm.phtml'
            ))
        ));
        //assign the search form to the layout place holder
        //substitute $this->view->form = $form; for a normal action/view
        $this->_helper->layout()->search = $searchForm;
    }

display this form in your view script with the normal <?php $this->form ?>.

You can use this method for any form you want to build with Zend_Form. So adding any element to your own fieldset would be simple.
