i have this code on my header of my theme <html xmlns="http://www.w3.org/1999/xhtml" dir="<?php bloginfo('text_direction'); ?>" xml:lang="<?php bloginfo('language'); ?>" xmlns:fb="http://www.facebook.com/2008/fbml" xmlns:og="http://ogp.me/ns#"> <!-- Facebook Opengraph --> <meta property="fb:app_id" content="app_id" /> <meta property="fb:admins" content="admins" /> <meta property="og:locale" content="en_US" /> <meta property="og:url" content="<?php the_permalink() ?>" /> <?php if (is_single()) { ?> <meta property="og:title" content="<?php single_post_title(''); ?>" /> <meta property="og:description" content="<?php echo strip_tags(get_the_excerpt($post->ID)); ?>" /> <meta property="og:type" content="article" /> <?php foreach (get_representative_images() as $image_url): ?> <meta property="og:image" content="<?php echo $image_url ?>" /> <?php endforeach; ?> <?php } else { ?> <meta property="og:site_name" content="<?php bloginfo('name'); ?>" /> <meta property="og:description" content="<?php bloginfo('description'); ?>" /> <meta property="og:type" content="website" /> <meta property="og:image" content="http://www.mysite.com/logo.png" /> <?php } ?> Code (markup): and in function of theme this: function get_representative_images() { global $post; $images = array('http://www.mysite.com/logo.png'); if ( has_post_thumbnail($post->ID) ) { // check if the post has a Post Thumbnail assigned to it. $image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'thumbnail'); array_unshift($images, $image_url[0]); } return $images; } Code (markup): in debugger it shows that everything is okay, but, 1.when I test a URL from some post it gives 2 photo options (the logo and the thumbnail). What do I have to change in the code in order when it finds a thumbnail in a post to show me only the thumbnail and when it doesn't find the thumbnail of the post then it will show as an option only the logo? 2. I noticed that in my text in expert, when there are "" & «» the text stops till the point it shows these when someone makes a "like" or "share" in a post. How can I make it to show the whole text that I have in the expert?
