html head 中的多描述元标记

本文介绍了html head 中的多描述元标记的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在 Zend FW 中，当我使用 helper 在循环中添加描述元标记时:

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

我的 html 头中有多个元标记.

我怎样才能防止它并在我的 html 头中有类似下面的内容:

解决方案

像这样扩展你自己的头部视图助手.

$this->headDescription($stringToAttach);

并提供一种将值推送到 headMeta 的方法

$this->headDescription()->pushToHeadMeta();//像这样的内部调用$this->view->headMeta('description', $this->getConcatedDescription());

其他选项是使用占位符.

//查看index.phtml$this->placeholder('description')->追加($desc1);//在查看other.phtml$this->placeholder('description')->追加($desc2);//在布局中echo $this->headMeta('description', $this->placeholder('description'));

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" />

解决方案

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'));
