Question

I am rendering zend file element using following decorator..

$decoratorFile = array
    (
        'File',
        'Errors',
        array(array('data' => 'HtmlTag'), array('tag' => 'td', 'class'=>'elements')),
        array('Label', array('tag' => 'td')),       
        array(array('row' => 'HtmlTag'), array('tag' => 'tr'))
    );

But i want to create a custom decorator like the following one…

class My_Decorator_Td extends Zend_Form_Decorator_Abstract
{
    public function buildLabel()
    {
        $element = $this->getElement();
        $label = $element->getLabel();
        if ($translator = $element->getTranslator()) {
            $label = $translator->translate($label);
        }
        if ($element->isRequired()) {
            $label .= '*';
        }
        $label .= '';
        return $element->getView()
                       ->formLabel($element->getName(), $label);
    }

    public function buildInput()
    {
        $element = $this->getElement();
        $helper  = $element->helper;
        return $element->getView()->$helper(
            $element->getName(),
            $element->getValue(),
            $element->getAttribs(),
            $element->options
        );
    }

    public function buildErrors()
    {
        $element  = $this->getElement();
        $messages = $element->getMessages();
        if (empty($messages)) {
            return '';
        }

        list($key, $error) = each($messages);
        return '<div class="errors">' .
               $error . '</div>';
    }

    public function buildDescription()
    {
        $element = $this->getElement();
        $desc    = $element->getDescription();
        if (empty($desc)) {
            return '';
        }
        return '<div class="description">' . $desc . '</div>';
    }

    public function render($content)
    {
        $element = $this->getElement();
        if (!$element instanceof Zend_Form_Element) {
            return $content;
        }
        if (null === $element->getView()) {
            return $content;
        }

        $separator = $this->getSeparator();
        $placement = $this->getPlacement();
        $label     = $this->buildLabel();
        $input     = $this->buildInput();
        $errors    = $this->buildErrors();
        $desc      = $this->buildDescription();

        $output = '<tr>'
            . '<td class="labels">'
                . $label
                . '</td>'
                . '<td class="elements">'
                . $input
                . $desc
                . $errors
                . '</td>'
                . '</tr>';

        switch ($placement) {
            case (self::PREPEND):
                return $output . $separator . $content;
            case (self::APPEND):
            default:
                return $content . $separator . $output;
        }
    }
}

I am using this one for text elements.
