Code to add Facebook meta tags for photo thumbs
While discussing this issue on Twitter, Rajupp was also looking for solution to this problem. Fortunately, coding skills of Sandep Dedhia came to rescue. You need to add following code between <head> and </head> of your WordPress blog file.
<?php $image = “”; preg_match_all( ‘|<img.*?src=['"](.*?)['"].*?>|i’, $post->post_content, $matches); if ( isset( $matches ) ) $image = $matches[1][0];?>
<?php if ((strlen(trim($image))!=0) && is_single()){ ?><meta property=”og:image” content=”<?php echo $image; ?>”/><?php } ?>
<?php if (is_single()) { ?>
<meta property=”og:type” content=”article”/>
<meta property=”og:url” content=”<?php echo get_permalink();?>”/>
<meta property=”og:title” content=”<?php wp_title(“”,true); ?>”/><?php } ?>
