設定ファイルの検証ルールにエラーが設定されていません

Question

configを介してフォームを検証しようとしています。私は空白の入力フィールドを提出すると、それはちょうど同じページを靴。私はadd_article.phpヘルプに表示されたエラーを必要とします....

のconfig/form_validation.php

<?php 

$config = [ 
     'add_article_rules' => [ 
            [ 
             'field' => 'title', 
             'label' => 'Article Title', 
             'rules' => 'required|alphadash' 
            ], 
            [ 
             'field' => 'body', 
             'label' => 'Article Body', 
             'rules' => 'required' 
            ] 

     ] 

]; 

マイコントローラー（admin.php）

<?php 
class Admin extends MY_Controller{ 

public function __construct(){ 
    parent::__construct(); 
    if(! $this->session->userdata('user_id')){ 

     return redirect('login'); 
    } 
} 

public function dashboard(){ 
    $this->load->model('articlesmodel','articles'); 

    $articles= $this->articles->article_list(); 

    $this->load->view('admin/dashboard',['articles'=>$articles]); 

} 

public function add_article(){ 
    $this->load->view('admin/add_article'); 

} 

public function store_article(){ 
    $this->load->library('form_validation'); 
    if($this->form_validation->run('add_article_rules')){ 
      //if sucesss 
    }else{ 

     return redirect('admin/add_article'); 

    } 
} 

public function edit_select(){} 

public function edit_article(){} 

public function delete_article(){} 
}

// Just Change Admin Controller method and view file 

// View File in add_article.php 
<?php echo form_open(); ?> 

//Controller File 
<?php 
defined('BASEPATH') OR exit('No direct script access allowed'); 

class Admin extends MY_Controller 
{ 

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

    public function add_article() 
    { 
     if ($this->form_validation->run('add_article_rules')) { 
      echo "Success"; 
     } else { 
      $this->load->view('admin/add_article'); 
     } 
    } 

    public function edit_select() 
    { 
    } 

    public function edit_article() 
    { 
    }
