multi description meta tags in html head

问题:

in Zend FW when I add description meta tag in loop using helper:

$this->headMeta()->appendName('DESCRIPTION', $des);

i got multi meta tags in my html head.

<meta name="DESCRIPTION" content="des1" />
<meta name="DESCRIPTION" content="des2" />

how can i prevent it and have something like below in my html head:

<meta name="DESCRIPTION" content="des1 des2" />

Extend you own head view helper callable like this.

$this->headDescription($stringToAttach);

and offer a method to push the values to headMeta

$this->headDescription()->pushToHeadMeta();
// internal call like this
$this->view->headMeta('description', $this->getConcatedDescription());

Other option is to use placeholders.

//in view index.phtml
$this->placeholder('description')
     ->append($desc1);
//in view other.phtml
$this->placeholder('description')
     ->append($desc2);

// in layout
echo $this->headMeta('description', $this->placeholder('description'));

Insted of

echo $this->headMeta ();

have in your layout

$u = '';
foreach ($this->headMeta ()->getContainer () as $y)
{
    if ($y->name == 'description')
    {
        $u .= $y->content;
    }
}
$this->headMeta ()->setName ('description', $u);

echo $this->headMeta ();

You can use this function to get your metas as an array (I put it in /application/plugins/common.php you can put it where you want) :

public function getMetasArray(Zend_View $view){
        $metas = array();
        foreach ($view->headMeta()->getContainer() as $y)
        {
            if($y->name!=''){
                $metas[$y->name] = $y->content;
            }

        }
        return $metas;
    }

and to call it when you want and as you want :

$metas = Application_Plugin_Common::getMetasArray($this);
echo $metas['description'];
