First change config.php in cofig directory
Search for $config['enable_hooks'] = false; make it ‘true’;
Add following in config/hook.php file
$hook['post_controller_constructor'] = array(
'class' => 'getSystem',
'function' => 'check',
'filename' => 'getsystem.php',
'filepath' => 'hooks'
);
For better configuration, try getting help from user_guide.
Create getsystem.php file in application/hooks directory
And paste the following:
<?php
//change the table name
if (!defined('BASEPATH')) exit('No direct script access allowed');
class getSystem
{
function check()
{
$CI =& get_instance();
$CI->db->query(”SELECT * FROM table_name”);
define('MAIL',true);
}
}
?>
try this controller
<?php
class Welcome extends Controller {
function Welcome()
{
parent::Controller();
}
function index()
{
echo MAIL;
$this->load->view('welcome_message');
}
}
?>
