How to Add Thesis Post Thumbnail In Facebook Without using WordPress Post Thumbnails

If you are using WordPress post thumbnails, you can use Facebook Open Graph Meta Data plugin by Paulund but Thesis theme for WordPress offers more than just post thumbnails and if you are using Thesis Thumbnails for WordPress (As we use it on my Indian Recipe Blog), it does not make sense to edit each post to add WordPress thumbnail for your post rather it is better to be using a code that can use Thesis Thumbnails and add the required open graph tags for Facebook.

I found the plugin code simple to edit and you can also see the same here. Using the above code as reference I added the option to use the Thesis Thumbnails for Open Graph tags. I also removed the code to fetch post excerpt from content and is using get_the_excerpt function of WordPress to get the description for the post in Facebook.

The Implementation

Just Add the following code to your custom_functions.php file in your Thesis Custom folder.

add_action('wp_head', 'add_fb_og_tags');

function add_fb_og_tags()
{
    if (is_single() && !is_admin()) 
    {
        global $post;
        if(get_the_post_thumbnail($post->ID, 'thumbnail')) {
            $thumbnail_id = get_post_thumbnail_id($post->ID);
            $thumbnail_object = get_post($thumbnail_id);
            $image = $thumbnail_object->guid;
        } else {
            $image = get_post_meta($post->ID, 'thesis_thumb', $single = true);
        }
        $description = get_the_excerpt($post->ID);
?>
<meta property="og:title" content="<?php the_title(); ?>" />
<meta property="og:type" content="article" />
<meta property="og:image" content="<?php echo $image; ?>" />
<meta property="og:url" content="<?php the_permalink(); ?>" />
<meta property="og:description" content="<?php echo $description ?>" />
<meta property="og:site_name" content="<?php echo get_bloginfo('name'); ?>" />
<?php     
    }
}
