// 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()
{
}
public function delete_article()
{
}
}
