Calling index() on form validation failure

I have tried with a validation function in a helper

You just have change the call to your function.


From this

PHP Code:

$this->form_validation->set_rules('f_eventname', 'Event Name', 'required|trim|min_length[3]|max_length[100]|callback_customAlpha'); 


to

PHP Code:

$this->form_validation->set_rules('f_eventname', 'Event Name', 
          array('required','other validation', array('customAlpha', 'customAlpha')); 


Your custom validation function is in an array to allow to set the error message.

A good decision is based on knowledge and not on numbers. - Plato
