Hi!
I'm working on a little thing for my website (modifying an existing wordpress plugin, so that I can style the comments from the authors even if they post on facebook on the comment in the posted on wordpress via the plugin).

My code (working) is awful :
PHP Code:
    function Comment_class($classes) {
            global 
$comment;
            if (!empty(
$comment) && $comment->comment_agent == 'AL2FB')
                
$classes[] = 'facebook-comment';
                        if (!empty(
$comment) && $comment->comment_agent == 'AL2FB' && esc_attr($comment->comment_author_url) == 'http://www.facebook.com/profile.php?id=randomnumber1')
                
$classes[] = 'comment-author-ec';
                        if (!empty(
$comment) && $comment->comment_agent == 'AL2FB' && esc_attr($comment->comment_author_url) == 'http://www.facebook.com/profile.php?id=randomenumber2')
                
$classes[] = 'comment-author-ness';
                        if (!empty(
$comment) && $comment->comment_agent == 'AL2FB' && esc_attr($comment->comment_author_url) == 'http://www.facebook.com/profile.php?id=randomnumber3')
                
$classes[] = 'comment-author-alice';
                        if (!empty(
$comment) && $comment->comment_agent == 'AL2FB' && esc_attr($comment->comment_author_url) == 'http://www.facebook.com/profile.php?id=randomnumber4' || !empty($comment) && $comment->comment_agent == 'AL2FB' && esc_attr($comment->comment_author_url) == 'http://www.facebook.com/profile.php?id=randomnumber5')
                
$classes[] = 'comment-author-joannv';
                        if (!empty(
$comment) && $comment->comment_agent == 'AL2FB' && esc_attr($comment->comment_author_url) == 'http://www.facebook.com/profile.php?id=randomnumber6')
                
$classes[] = 'comment-author-kanata';
            return 
$classes;
        } 

Here is my attempt :

PHP Code:
function Comment_class($classes) {
            global 
$comment;
                        if (!empty(
$comment) && $comment->comment_agent == 'AL2FB' && esc_attr($comment->comment_author_url) == $urlfacebook)
                
$classes[] = $facebookclasshere;
                        switch (
$urlfacebook) {
            
                case 
'http://www.facebook.com/profile.php?id=randomnumber1':            
                
$facebookclasshere 'comment-author-ec';
                break;
                
                case 
'http://www.facebook.com/profile.php?id=randomnumber2':
                
$facebookclasshere 'comment-author-ness';
                break;
                
                case 
'http://www.facebook.com/profile.php?id=randomnumber3':
                
$facebookclasshere 'comment-author-alice';
                break;
                
                case 
'http://www.facebook.com/profile.php?id=randomnumber4':                
                case 
'http://www.facebook.com/profile.php?id=randomnumber5':
                
$facebookclasshere 'comment-author-joannv';
                break;
                
                case 
'http://www.facebook.com/profile.php?id=randomnumber6':
                
$facebookclasshere 'comment-author-kanata';
                break;
                }
            return 
$classes;
    } 
No idea why it's not working Somebody could give me a hint? Thanks a lot !
