   Hi there,

   I'm working on a plugin with custom post_type.

   I've added a hook for the 'save_post' action so I can process the extra meta data required by my post_type:

   add_action('save_post', array('myObj', 'on_save_post'));

   and the function is:

   class myObj {
    function on_save_post($post_ID, $post)
    {
     // process here
    }
   }

   However, the second argument ($post) doesn't get passed when I 'Publish' the post.
   In fact I get a PHP Warning message:
   Warning: Missing argument 2 for myObj::on_save_post in <file> on line <line_no>

   the action call inside wp_insert_post() is
   do_action('save_post', $post_ID, $post);

   What am I doing wrong?

   That's because your add_action call defaults to supporting one argument, update your add_action call to..

   add_action('save_post', array('myObj', 'on_save_post'), 10, 2 );

   Oh snap! Forgot about that.

   Thank you very much, Mark.
