php - Codeigniter - adding multiple custom validation -


is possible add 2 or more custom validation functions using same field?

$this->form_validation->set_rules('myfield', 'my field','required|my_method1|my_method2');

eg. my_method1 check string format , my_method2 check existence of string in database.

seems first method works , second 1 ignored. because i'm using same parameter both functions?

thanks.

you can!

in each my_method_n($x) function, must inform them prefix name callback_, instance: callback_my_function1|callback_my_function2.

take @ question explains how can use multiple callback functions , syntax in manual.
