Zend Framework: How do I remove the decorators on a Zend Form Hidden Element?

Question

I\'m trying to remove the default decorators on a hidden form element. By default, the hidden element is displayed like this:

Hidden Element Label          


        

Answer 1

For hidden field you need only one decorator - ViewHelper:

$field = new Zend_Form_Element_Hidden('id');
$field->setDecorators(array('ViewHelper'));

This will render only the input field, without Dt-Dd wrapper and label.

Answer 2

As mentioned in other posts setDisableLoadDefaultDecorators(true) doesn't work if they're already loaded... BUT clearDecorators() does!

Answer 3

Use this:

    foreach ($this->getElements() as $element) {

        $decorator = $element->getDecorator('label');
        if (!$decorator) {
            continue;
        }
        $decorator->removeOption('tag');
    }

Answer 4

Well, 2012 and still the same issue. If you remove the decorators, the html won't validate. If you leave them, the hidden elements take up space. In all of my projects I have a CSS helper .hidden, so I just apply it to the <dd> and unset the label:

$element = new Zend_Form_Element_Hidden('foo', array('value' => 'bar'));
$element->removeDecorator('Label');
$element->getDecorator('HtmlTag')->setOption('class', 'hidden');

Valid html(5), nice looking forms. This can also go into a custom decorator for the hidden fields.

EDIT

This is how I put it into my own form element:

class Exanto_Form_Element_Hidden extends Zend_Form_Element_Hidden
{
    public function render(Zend_View_Interface $view = null)
    {
        $this->removeDecorator('Label');
        $this->getDecorator('HtmlTag')->setOption('class', 'hidden');
        return parent::render($view);
    }
}

Answer 5

here is what takeme2web from http://www.phpfreaks.com/forums/index.php?topic=225848.0 suggests

$yourhiddenzendformelement->setDecorators(array('ViewHelper'));

Answer 6

// based on above - a simple function to add a hidden element to $this form

/**
 * Add Hidden Element
 * @param $field
 * @param value
 * @return nothing - adds hidden element
 * */
public function addHid($field, $value){     
    $hiddenIdField = new Zend_Form_Element_Hidden($field);
    $hiddenIdField->setValue($value)
          ->removeDecorator('label')
          ->removeDecorator('HtmlTag');     
    $this->addElement($hiddenIdField);
}
