Custom Decorator for Zend File Element - php

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.
How to create a custom decorator decorator for file element. Any Help?

Answer 2

I had the same problem and came up with the solution to create a custom decorator that extends the default File decorator and override the render method to add your markup :
<?php
class My_Super_Custom_File_Decorator extends Zend_Form_Decorator_File
{
public function render($content)
{
$element = $this->getElement();
if (!$element instanceof Zend_Form_Element) {
return $content;
}
$view = $element->getView();
if (!$view instanceof Zend_View_Interface) {
return $content;
}
$name = $element->getName();
$attribs = $this->getAttribs();
if (!array_key_exists('id', $attribs)) {
$attribs['id'] = $name;
}
$separator = $this->getSeparator();
$placement = $this->getPlacement();
$markup = array();
$size = $element->getMaxFileSize();
if ($size > 0) {
$element->setMaxFileSize(0);
$markup[] = $view->formHidden('MAX_FILE_SIZE', $size);
}
if (Zend_File_Transfer_Adapter_Http::isApcAvailable()) {
$markup[] = $view->formHidden(ini_get('apc.rfc1867_name'), uniqid(), array('id' => 'progress_key'));
} else if (Zend_File_Transfer_Adapter_Http::isUploadProgressAvailable()) {
$markup[] = $view->formHidden('UPLOAD_IDENTIFIER', uniqid(), array('id' => 'progress_key'));
}
if ($element->isArray()) {
$name .= "[]";
$count = $element->getMultiFile();
for ($i = 0; $i < $count; ++$i) {
$htmlAttribs = $attribs;
$htmlAttribs['id'] .= '-' . $i;
$markup[] = $view->formFile($name, $htmlAttribs);
}
} else {
$markup[] = $view->formFile($name, $attribs);
}
$markup = implode($separator, $markup);
switch ($placement) {
case self::PREPEND:
return $markup . $separator . $content;
case self::APPEND:
default:
return $content . $separator . '<div>My Super Custom Markup : '.$markup.'</div>';
}
}
}
You should follow the basics to create a custom decorator (prefixPath, etc.) and apply your new decorator to your file element instead of 'File'.
