[pmwiki-users] Insert meta tag in <head>

Thu Feb 11 03:55:25 CST 2016

Something like this in config.php should do:

   $HTMLHeaderFmt['facebook'] = '
     <meta property="og:title" content="$Title" />
     <meta property="og:type" content="article" />
     <meta property="og:url" content="$PageUrl" />
     <meta property="og:description" content="$Description" />
   ';

If you call this from within a function, before it declare:

   global $HTMLHeaderFmt;

$Title is the title or the name of your page, to control it you can 
insert in the page:

    (:title Your page:)

$PageUrl is the regular address of the page, without any parameters 
(search, subpage, anchor section...).

$Description can be controlled from the page with this:

   (:description Here is a good description. 2 phrases should do.:)

One thing it doesn't have is a picture tag:

   <meta property="og:image" 
content="http://your/site/uploads/$Group/$Name.jpg" />

then you upload a file $Name.jpg where $Name is the name of the page, 
for example HomePage.jpg or WikiSandbox.jpg. It is a bad idea to have 
such a tag and to not have the picture it references. If you don't use 
this tag, Facebook should automatically select the first large picture 
in the main content area.
