Facebook Meta Tag og:image PHP condition

I used that PHP code for og:image meta tag but it doesn't work, it's right but it doesn't call the right source of the image.

<?php JFactory::getDocument(); $document->addCustomTag('<meta property="og:image" content="http://www.sell4masari.com/images/com_adsmanager/ads/<?php.$img->image?>" />');?>

So I will appreciate any help from anyone.


You're putting the <?php tags inside the quotes, so it is not being processed:

content="[...]/ads/<?php.$img->image?>" />');

You need to build the string through concatenation, like so:

<?php JFactory::getDocument(); $document->addCustomTag('<meta property="og:image" content="http://www.sell4masari.com/images/com_adsmanager/ads/' . $img->image . '" />');?>
