Question

我创建了一个库My_validation并扩展了form_validation。当我提交空白表单时，错误消息未显示。但如果我不扩展则其工作正常。

表单控制器

 <?php

class Form extends CI_Controller {

        public function __construct()
        {
                parent::__construct();
                $this->load->helper(array('form', 'url'));
                $this->load->library(array('form_validation','MY_validation'));
        }

        public function index()
        {
            $this->my_validation->set_rules('first_name', 'First Name', 'required|alpha'); 


                if ($this->my_validation->run() == FALSE)
                {

                    $this->load->view('myform');
                }


        }



}

My_validation库

    <?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_validation extends CI_Form_validation
{

    public function test()
    {
        return true;
    }
}

Answer 1

试试这个：

class MY_validation extends CI_Form_validation {

    public function __construct($config = array()){
        parent::__construct($config);
    }

    public function test(){
        return "Hello World!";
    }

}

codeigniter扩展表单验证不起作用
