  |   By  |  0 Comments

If you want to control what image and content Facebook uses when someone likes a post/page on your WordPress site, then add this snippet to your theme functions.php. Any Facebook likes will then use the featured image from that post or page.

A similar thing can be done with Twitter – called Twitter cards – a simple version is previewed below. It can add a neat little card under a tweeted url from your site if you use the code below and apply to the program! It takes 5-10 days to be improved, so do it now!


How to get it working
1) Use the code below in your theme and get it uploaded
2) Go to to check it works with a url from your site with my code!
3) Go to to apply.

[code]add_action( ‘wp_head’, my_theme_facebook_meta_tags );
function my_theme_facebook_meta_tags()
global $post;
echo'<!–Facebook tags–>’;
if(function_exists( ‘has_post_thumbnail’ )&& has_post_thumbnail( $post->ID ))
$thumb = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), ‘thumbnail’ );
echo'<meta property=”og:image” content=”‘.$thumb[0].'”/>’;
if(!empty($thumb)) echo'<meta property=”og:image” content=”‘.$thumb.'”/>’;
echo'<meta property=”og:url” content=”‘.get_permalink($post->ID).'”/>’;
//post title
echo'<meta property=”og:title” content=”‘.get_the_title() .'”/>’;
//site name
echo'<meta property=”og:site_name” content=”‘.get_bloginfo(‘name’).'”/>’;
if ( !empty($post->post_excerpt) ) {
$description = strip_tags(strip_shortcodes($post->post_excerpt));
$description = my_theme_wordlimit(strip_tags(strip_shortcodes($post->post_content)));
echo ‘<meta property=”og:description” content=”‘.$description.'”/>’;
echo'<!–End Facebook tags–>’;
function my_theme_wordlimit($string, $length = 50, $ellipsis = “…”)

$words = explode(‘ ‘, $string);
if (count($words) > $length)
return implode(‘ ‘, array_slice($words, 0, $length)) . $ellipsis;
return $string;
