回调表单验证未在HMVC

Question

工作，我在用我回电话了表单验证的一个问题。 验证应检查tbl_fees_type是否有创建一个新的收费类型之前，现有的fees_type_name，如果它已经存在，它会显示一个错误的费用类型已经存在。

我知道所需的表单验证工作，因为它表明它是必需的，但是当涉及到回调验证是否存在利用回调它不工作，检查从数据库中的信息。

这是我的代码：

所以我有一个Feestype控制器这样

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

     class Feestype extends MX_Controller { 

     public function __construct() { 
      parent::__construct(); 

      // loading the fees type model 
      $this->load->model('model_feestype'); 

      // loading the form validation library 
      $this->load->library('form_validation'); 

     } 

     public function index() { 

      $this->load->view('feestype'); 

     } 

     public function create() 
     { 
     $validator = array('success' => false, 'messages' => array()); 

     $validate_data = array(
      array(
      'field' => 'fees_type_name', 
      'label' => 'Fees Type Name', 
      'rules' => 'trim|required|callback_validate_feestypename' 
             //this is the callback 
     ), 
      array(
      'field' => 'fees_type_role', 
      'label' => 'Fees Type Role', 
      'rules' => 'trim|required|' 
     ) 
     ); 

     $this->form_validation->set_rules($validate_data); 
     $this->form_validation->set_error_delimiters('<p class="text-danger">','</p>'); 

     if($this->form_validation->run() === true) { 
      $create = $this->model_feestype->create();   
      if($create === true) { 
      $validator['success'] = true; 
      $validator['messages'] = "Successfully added"; 
      } 
      else { 
      $validator['success'] = false; 
      $validator['messages'] = "Error while inserting the information into the database"; 
      }  
     } 
     else { 
      $validator['success'] = false; 
      foreach ($_POST as $key => $value) { 
      $validator['messages'][$key] = form_error($key); 
      }  
     } // /else 

     echo json_encode($validator); 
     } 

     // call back validation function to do 
     public function validate_feestypename() 
     { 
     $validate = $this->model_feestype->validate_feestypename(); 

     if($validate === true) { 
      $this->form_validation->set_message('validate_feestypename', 'The {field} already exists'); 
      return false;   
     } 
     else { 
      return true; 
     } 

     } 

    } 

    ?> 

，这是model_feestype.php型号

<?php if (!defined ('BASEPATH')) exit ('No direct script access allowed'); 

       class Model_Feestype extends CI_Model { 


        public function __construct() { 

         parent:: __construct(); 

        } 

       public function create() 
       { 
        $insert_data = array(
         'fees_type_name' => $this->input->post('fees_type_name'), 
         'fees_type_role' => $this->input->post('fees_type_role') 
        ); 
        $status = $this->db->insert('tbl_fees_type', $insert_data);  
        return ($status === true ? true : false); 
       } 



       public function validate_feestypename() 
       { 
        $feestypeName = $this->input->post('fees_type_name'); 
        $sql = "SELECT * FROM tbl_fees_type WHERE fees_type_name = ?"; 
        $query = $this->db->query($sql, array($feestypeName)); 

        return ($query->num_rows() == 1 ? true : false);   
       } 

      } 
      ?> 

，这是我的模式表单视图PHP文件。

<div class="modal fade" tabindex="-1" role="dialog" id="addFeetype"> 
        <div class="modal-dialog" role="document"> 
        <div class="modal-content"> 
         <div class="modal-header"> 
         <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button> 
         <h4 class="modal-title">Add Fees Type</h4> 
         </div> 

         <form method="post" action="feestype/create" id="createFeetypeForm"> 
          <div class="modal-body"> 



           <div class="form-group"> 
           <label for="fees_type_name">Fees Type Name</label> 
           <input type="text" class="form-control" id="fees_type_name" name="fees_type_name" placeholder="Fees Type Name"> 
           </div> 

           <div class="form-group"> 
           <label for="fees_type_name">Fees Type Role</label> 
           <select class="form-control" name="fees_type_role" id="fees_type_role"> 
            <option></option> 
            <option>School Fees</option> 
            <option>Personal Fees</option> 
           </select> 
           </div> 


          </div> 

          <div class="modal-footer"> 
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> 
          <button type="submit" class="btn btn-primary">Save changes</button> 
          </div> 

         </form> 

        </div><!-- /.modal-content --> 
        </div><!-- /.modal-dialog --> 
       </div><!-- /.modal --> 

需要验证的窗体看起来像这样工作。 Form validation required working

这是我想要达到的样品形式，它具有相同的源代码，但它在笨（不HMVC）中运行，但它不是我的工作（HMVC）工作。

Woking callback validation should look like this

Answer 1

所有你需要做的，使回调在HMVC工作是

MY_Form_validation.php

<?php 

class MY_Form_validation extends CI_Form_validation { 

    function run($module = '', $group = '') { 
     (is_object($module)) AND $this->CI = &$module; 
     return parent::run($group); 
    } 

} 

然后在运行部分添加$this在run($this)

$this->form_validation->run($this) 

Answer 2

在文件夹中创建库类MY_Form_validation

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

function run($module = '', $group = ''){ 
(is_object($module)) AND $this->CI = &$module; 
return parent::run($group); 
} 

// call back validation function to do 
     public function validate_feestypename() 
     { 
     $this->CI =& get_instance(); 
     $this->CI->load->model('model_feestype'); 
     $validate = $this->CI->model_feestype->validate_feestypename(); 

     if($validate === true) { 
       $this->CI->form_validation->set_message->set_message('validate_feestypename', 'The {field} already exists'); 
      return false;   
     } 
     else { 
      return true; 
     } 

     } 

}
