     $this->form_validation->set_rules('inputcardtype','Select Card Type','required|callback_check_default'); 
     $this->form_validation->set_message('check_default', 'Please select the month of expiration'); 
     $this->form_validation->set_rules('inputcardnumber', 'Card Number', 'trim|required|xss_clean|callback_cardnumber_validation');

     $inputcardtype = $this->input->post('inputcardtype'); 
     if($this->form_validation->run()==false){ 
      $this->index(); 
     }else{ 

     } 

    } 

    function cardnumber_validation($string = NULL) { 
     $this->load->helper('creditcardvalidation'); 

     if(checkCreditCard ($string, $cardtype, $ccerror, $ccerrortext)) { 
      return TRUE; 
     } 
     else{ 
      $this->form_validation->set_message("cardnumber_validation", 'The %s is not valid.'); 
      return FALSE; 
     } 
    }

的回调需要一个功能之后被命名。

如果您有:

callback_check_default 

你需要呼吁的函数:

function check_default() { 
    //Your validation here 
    } 

是否回答你的问题?
