Hi, can someone help me out. I want to make custom menu in header for Instant Messenger, and i managed to get uniform resource locator but i can't figure out, how to get message count. I i've tried this <?php echo $message_count; ?>, but for some reason it doesn't work. What did I missed?

Try...
<?php if($mes_counter > 0) { ?>
<span class="counter"><?php echo $mes_counter; ?></span>
<?php } ?>

You miss most important part

  $message_count = 0;
  if(function_exists('im_messages')) {
    if(osc_is_web_user_logged_in()) {
      $message_count = ModelIM::newInstance()->countMessagesByUserId( osc_logged_user_id() );
      $message_count = $message_count['i_count'];
    }
  }

Hi
 
I want to express my gratitude to both of you, it's working perfectly  .

Thank you.
