Joomla Template - 修改／添加 Meta Tag (Facebook Share)

.. Joomla 1.5 / 2.5 Template 内的:

<jdoc:include type="head" />

会加入默认的 <meta tag>，我们可以用以下 code 自由修改／添加 Meta Tags：

$mydoc =& JFactory::getDocument();

//edit <meta name="Description" content="XXX">
$mydoc->setDescription('MY_DESCRIPTION');

Facebook Share 用 meta tag:

$mydoc =& JFactory::getDocument();

//Add <meta property="og:title" content="XXX" />
$mydoc->setMetaData('og:title', 'MY_TITLE');   

//Add <meta property="og:site_name" content="XXX" />
$mydoc->setMetaData('og:site_name', "MY_SITE_NAME");   
           
//Add <link rel="image_src" href="xxx" />
$mydoc->addHeadLink( 'MY_IMAGE_URL' , 'image_src', 'rel' );

 
最后，你亦可直接修改 system source code:

Edit: libraries > joomla > html > html > behaviors.php
