   Hi guys

   I'm trying to replace the value of a meta tag with something dynamic.

   This is the code i wish to change:
   <meta property="og:image" content="http://www.gallozone.co.za/wp-content/uploads/2010/08/gallozone.jpg" />

   I would like the value of that meta tag to be something unique for every post.

   A custom field maybe?

   I would like to add a custom field in my post edit area along with a value (the url of a thumbnail image) and then I would like it to appear in the meta tag.

   How can I have this done?
   Is there a way to assign a unique meta tag to each post?

   So there is no wordpress wizard who knows the answer to this?

   I'm no PHP superstar, but I did string this together and it works on my site at least.

   ___

   In the header.php, before the </head> tag.

   <!-- Facebook Open Graph Image -->
<?php if(get_post_meta($post->ID, 'fb_img')){ ?>
<meta property="og:image" content="<?php echo get_post_meta($post->ID, 'fb_img', $single = true); ?>" />
<?php } else { ?>
<meta property="og:image" content="http://www.THE-URL-OF-THE-DEFAULT-IMAGE" />
<?php } ?>


   fb_img - This is the custom field name. Use the full url (starting with "http://") in the "value" field.

   http://www.THE-URL-OF-THE-DEFAULT-IMAGE - enter the url of the default image to be used when no image is set as a custom field.

   I've also used the following successfully.

   Control the title appearing on shared content and Facebook Comments plugin.
   <meta property="og:title" content="<?php the_title() ?>" />

   Control the url appearing on shared content and Facebook Comments plugin.
   <meta property="og:url" content="<?php the_permalink() ?>" />

   I hope this works for you.
