Facebook like webpage button description

问题

I see the webpage title, link, image, but I cannot get any description. My client want's a describing text when a user has clicked like on the webpage. Is this not possible??

I had to use the old way of sharing since the new doesn't work together with the other things on the site.

I have ran it through the Facebook Debugger and the only problem it states is:

Open Graph Warnings That Should Be Fixed:

Parser Mismatched Metadata: The parser's result for this metadata did not match the input metadata. Likely, this was caused by the data being ordered in an unexpected way, multiple values being given for a property only expecting a single value, or property values for a given property being mismatched. Here are the input property =>content pairs that were not seen in the parsed result: 'og:description => the site desc'

However I think this is only because I use <meta name="description"> as well. Because it does fetch and display this information in the debugger:

Raw Open Graph Document Information

Meta Tag:   <meta property="og:url" content="http://website.nu/" />
Meta Tag:   <meta property="og:image" content="http://website.nu/img/img200x200.jpg" />
Meta Tag:   <meta property="og:title" content="website title" />
Meta Tag:   <meta property="og:type" content="website" />
Meta Tag:   <meta property="og:site_name" content="site_name" />
Meta Tag:   <meta property="fb:admins" content="[my fb id]" />
Meta Tag:   <meta property="og:description" content="site desc" />

Website source code:

<head>  
    <meta name="description" content="Page description">

    <meta property="og:url" content="http://website.nu/"/>
    <meta property="og:image" content="http://website.nu/img/img_200x200.jpg"/>
    <meta property="og:title" content="Site title"/>
    <meta property="og:type" content="website"/>    
    <meta property="og:site_name" content="Site name"/> 
    <meta property="fb:admins" content="[my_fb_id]"/>
    <meta property="og:description" content="Page description, expected to output"/>    
</head>

回答1:

Try putting the <meta name="description"> tag after the <meta property="og:description"> tag.

回答2:

The og:description needs to be after the og:image property. At least that was working for me. description after og:description or removing the description-metatag didn't change anything.

回答3:

try to trim your content for example:

echo '<meta property="og:description" content="' . trim($content) . '"/>';
