about do_action and add_action

  • 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
