   Hi;
   I'm creating a new (fantastic!) plugin... :)

   I have a little problem using do_action and add_action :

   I got a function

   function classifieds_manage_classified_save_step {
   ...
   	///CHECK DATA WITH PHP FILE
   	do_action('classifieds_manage_step_check_data');
   ...
   }

   If false is returned somewhere in that function, my object is not saved.

   Somewhere else; I put
   

   //MANAGE|CHECK
   add_action( 'classifieds_manage_step_check_data','classifieds_manage_step_settings_check_data');

   So; the function classifieds_manage_step_settings_check_data is called where I have do_action('classifieds_manage_step_check_data');.

   That function classifieds_manage_step_settings_check_data returns 'true' or 'false'; but how can I "transmit" it to function classifieds_manage_classified_save_step ?

   Have I to use arguments somewhere and how ?

   Thanks !

   Have a look into filters.

   Filters filter a value, Ie:

   function auth($user, $pass) {
   $authed = false;
   $authed = apply_filters('auth_user', $authed, $user, $pass);
   return $authed;
   }
   add_filter('auth_user', 'dd_is_great', 10, 3); //10 = default priority, 2 = i want 3 args to be passed through instead of 1
   function dd_is_great($authed, $user, $pass) {
    if ( 'dd32' == $user && 'grockenhiem' == $pass )
      return true;
    else
     return $authed;
   }

   In other words.. Actions are Actions, They fire to say something has happened. Filters filter a variable, Its the best way to return data..

   I'm not sure using filters or actions is the best method at all for you.. Maybe wrapping everything in a class could be a possibility
