Codeigniter controller controller inheritance problem example analysis, codeigniter controller

This article describes the Codeigniter controller controller inheritance problem with an example. Share it with everyone for your reference, the details are as follows:

In projects, there is often a situation where each page in the background must judge the Session to determine whether the user is logged in. For Codeigniter, each controller will be considered to inherit a common controller.

For example: AdminBase is the public controller of the application background. Each application background controller inherits the public AdminBase, but at the same time, make sure that AdminBase also inherits CI_Controller.

The same is true for HomeBase at the front desk.

The specific implementation is very simple, just create a new MY_Controller.php under application/core, as follows
(MY_ is configurable, go to application/config/config.php file and find this item: $config['subclass_prefix'] = 'MY_';)

class MY_Controller extends CI_Controller
{
function __construct()
{
parent::__construct();
}
}
class AdminBase extends MY_Controller
{
function __construct()
{
parent::__construct();
......
}
......
}
class HomeBase extends MY_Controller
{
function __construct()
{
parent::__construct();
......
}
......
}

Then the controller in application/controllers can be inherited, such as application/controllers/admin/blog.php

class Blog extends AdminBase
{
function __construct()
{
parent::__construct();
......
}
......
}
