Facebook og data not showing on blog posts

I’m trying to set up the Facebook go data on blog posts, I have it working fine on standard pages but I don’t anything at all from the page attributes on blog post pages.

Here is my diagnostic:

I have this in the head of my post page:

<?php 
        # get the post
        $post = perch_blog_custom(array(
      'filter'        => 'postSlug',
      'match'         => 'eq',
      'value'         => perch_get('s'),
      'skip-template' => 'true',
      'return-html'   => 'true',
        ));

        # set up the variables
        $title       = $post['0']['postTitle'];
        $description = strip_tags($post['0']['excerpt']);
        if (isset($post[0]['fbimage'])) {
        $fbimage = $post[0]['fbimage'];
        } else {
        $fbimage = '';
        }

        # use the variables in the array value 
        perch_page_attributes_extend(array(
        'description'    => $description,
            'og_description' => $description,
            'og_title'       => $title,
            'og_type'        => 'article',
            'sharing_image'  => $fbimage,
            'og_author'      => 'Helena Clayton',
        ));

        perch_page_attributes();
    ?>

What result do you get?

Hello Drew, it doesn’t output anything from the attributes at all, I’ve turned on debugged and there are no errors. On the non-blog pages I used:

<?php 
        $domain        = 'http://'.$_SERVER["HTTP_HOST"];
        $url           = $domain.$_SERVER["REQUEST_URI"];
        $sitename      = "Helena Clayton";
        $twittername   = "@helenaclayton";
        $sharing_image = '/images/for_facebook.jpg';

        PerchSystem::set_var('sitename',$sitename);
        PerchSystem::set_var('domain',$domain);
        PerchSystem::set_var('url',$url);
        PerchSystem::set_var('sharing_image',$sharing_image);
        PerchSystem::set_var('twittername',$twittername);

        perch_page_attributes(array(        
            'template' => 'default.html'    
        ));
    ?>

which works fine.

Both use the same template.

We've just released Blog 5.0 to make this simpler. It has a dedicated section for entering Facebook and Twitter meta data, and a simple function to output it all in the head of your page.
