Question

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'));
