   Hello people,

   I have a question about add_meta_box. Is there any way I can pass some arguments to the callback function. Here's what I mean:

   function my_callback ($parameter1, $parameter2) {
   echo $parameter1;
   echo $parameter2;
   }
   
   function add_my_meta_box() {
   $var1 = "Blabla";
   $var2 = "Something"
   add_meta_box($id, $title, my_callback (<< Those 2 vars should be passed to this function), $page, $context, $priority);
   }

   Is there any way to do this? I would rather not use $_SESSION values.

   Thnx!

   What do you mean? $_SESSION variables or the my_callback($var1, $var2)?

   If you haven't figured it out yet, since v2.8 there's another parameter you didn't show, $callback_args, i.e. here's the function prototype:

   add_meta_box($id, $title, $callback, $page, $context = 'advanced', $priority = 'default', $callback_args=null)

   In your example passed an array containing your two variable's values:

   function add_my_meta_box() {
   $var1 = "Blabla";
   $var2 = "Something"
   add_meta_box($id, $title, my_callback (<< Those 2 vars should be passed to this function), $page, $context, $priority, array('foo'=>$var1,'bar'=>$var2));
   }

   Then in your example it would look like this:

   function my_callback ($post, $metabox) {
   echo $metabox['args']['foo'];
   echo $metabox['args']['bar'];
   }

   Hope this helps.

   @MikeSchinkel - Thanks, the documentation wasn't great on the Codex. $post, then $vars!
