Vous connaissez tous Zend_View_Helper_Url qui permet de créer une url rapidement dans une view. La syntaxe est la suivante : $this->url(array('controller' => 'index', 'action' => 'about', 'arg0' => 'value'));. Il faut avouer que c'est assez sympatique. Mais il est laborieux d'écrire systématiquement la balise <a />. Voici donc un helper très basique reprennant les arguments de url(). La seule modification est l'ajout du premier argument. Celui-ci contiendra la texte à mettre dans la balise <a />

Exemple :

<?php
echo $this->link('A propos de...', array('controller' => 'index', 'action' => 'about', 'arg0' => 'value'));?>
<a href="/index/about/arg0/value">A propos de...</a>

Le Zend_View_Helper_HeadStyle de Zend Framework a un bug non corrigé depuis très longtemps, à savoir ZF-3406. Le bug en question empèche la création d'une balise <style> avec un attribut media contenant une liste de différents médias.

$this->headStyle()->captureStart(Zend_View_Helper_Placeholder_Container_Abstract::APPEND, array('media' => 'screen'))
// Displays <style type="text/css" media="screen">
 
$this->headStyle()->captureStart(Zend_View_Helper_Placeholder_Container_Abstract::APPEND, array('media' => array('screen', 'projection', 'tv')))
// Should display <style type="text/css" media="screen projection tv">
// But displays <style type="text/css">

Donc, voici un nouvel helper modifié qui fait son job :

<?php
 
require_once 'Zend/View/Helper/HeadStyle.php';
 
/**
 * HeadStyle helper
 *
 * @uses helper Zend_View_Helper
 */
class App_View_Helper_HeadStyle extends Zend_View_Helper_HeadStyle {
 
	/**
	 * Convert content and attributes into valid style tag
	 * 
	 * @param  stdClass $item Item to render
	 * @param  string $indent Indentation to use 
	 * @return string
	 */
	public function itemToString(stdClass $item, $indent) {
		$attrString = '';
		if (!empty($item->attributes)) {
			foreach($item->attributes as $key => $value) {
				if (!in_array($key, $this->_optionalAttributes)) {
					continue;
				}
				if ('media' == $key) {
					if (is_string($value) && preg_match('/^[\w ]+$/', $value)) {
						$value = explode(' ', $value);
					}
					if (is_array($value)) {
						$stringValue = '';
						$separator = '';
						foreach ($value as $mediaType) {
							if (!in_array($mediaType, $this->_mediaTypes)) {
								continue;
							}
							$stringValue .= $separator.$mediaType;
							$separator = ' ';
						}
						$value = $stringValue;
					} else {
						if (!in_array($value, $this->_mediaTypes)) {
							continue;
						}
					}
				}
				$attrString .= sprintf(' %s="%s"', $key, htmlspecialchars($value));
			}
		}
 
		$html = '<style type="text/css"' . $attrString . '>' . PHP_EOL 
			. $indent . '<!--' . PHP_EOL . $indent . $item->content . PHP_EOL . $indent . '-->' . PHP_EOL 
			. '</style>';
 
		return $html;
	}
 
}

On spécifier au Broker de le charger de préférence à celui de zf :

$this->view->setHelperPath(Zend_Registry::get('conf')->paths->views.'helpers/', 'App_View_Helper');

Et ça s'utilise de cette façon :

$this->headStyle()->captureStart(Zend_View_Helper_Placeholder_Container_Abstract::APPEND, array('media' => array('screen', 'print', 'projection', 'tv')));
$this->headStyle()->captureStart(Zend_View_Helper_Placeholder_Container_Abstract::APPEND, array('media' => 'screen print projection tv'));
