CodeIgniter custom validation errors for each rule per each field

Question

I'm using CodeIngiter 2.1 and I wanna define custom validation errors for each rule per each field. The fields are as follows.

array(
'field' => 'firstname',
'rules' => 'required',
    'error' => 'This field cannot be empty.'
),
array(
'field' => 'email',
'rules' => 'required',
    'error' => 'The email cannot be empty.'
)

But In CodeIgniter only one error message is defined for one rule. So how to override that one and Please suggest some solutions for getting different errors for perticular field. The work is more appreciated.

Answer 1

Try using the CI function :

   set_message();

All of the native error messages are located in the following language file:

   language/english/form_validation_lang.php

To set your own custom message you can either edit that file, or use the following function:

   $this->form_validation->set_message('rule', 'Error Message');

Hope it will help;
