Dear Joomla community,
I'm working on a little system plugin to inject Facebook Open Graph properties into an article. Therefore I've been using
$document->setMetaData(). But now I discovered that this adds
<meta name=""> tags to the header of the page, but Facebook expects
<meta property=""> tags.
What's the easiest way to put a
<meta property=""> tag into the page header?
Please explain in as much detail as possible, as I'm absolutely new to Joomla plugin developemnt.
Any advice is appreciated, Thank you.
