About the use of multi-layer controllers and multi-level controllers in the thinkPHP framework

This article mainly introduces the use of TP (thinkPHP) framework multi-layer controllers and multi-level controllers, and analyzes the structure, principles and usage of thinkPHP framework multi-layer controllers and multi-level controllers in the form of examples. Friends in need can refer to

This article describes the use of multi-layer controllers and multi-level controllers in the TP (thinkPHP) framework. Share it with everyone for your reference, the details are as follows:

The directory structure of the multi-layer controller is as follows:

├─ Controller Access Controller
│ ├─UserController.class.php
│ ├─BlogController.class.php
│ ...
├─Event Event Controller
│ ├─UserEvent. class.php
│ ├─BlogEvent.class.php
│ ...

Add multi-layer controllers to the App application. No need to add any parameters, just follow the above Just create the file directly.

Multi-level controller instantiation:

/* * 多层控制器实例化 即和访问控制器Controller同级目录的Service时 可用D方法或A方法 * 注：访问控制器的名称是通过DEFAULT_C_LAYER设置的，默认是Controller，访问控制器负责外部交互响应， 其它的控制器层和外部隔离，只能内部调用。定义其他的控制器层，则不一定必须要继承系统的Controller类或其子类，通常需要输出模版的时候才需要继承Controller类。 */ D('Admin', 'Service'); //或者 A('User','Event'); A('Admin/Blog','Event'); //假设当前模块是Home模块 // 实例化Home模块的User事件控制器 $User = new \Home\Event\UserEvent(); // 实例化Admin模块的Blog事件控制器 $Blog = new \Admin\Event\BlogEvent();

And the multi-level controller The directory structure is like this:

├─Controller access controller
│ ├─User User classification (group)
│ │ ├─UserTypeController.class. php
│ │ ├─UserAuthController.class.php
│ ...
│ ├─Admin Admin rating (group)
│ │ ├─UserController.class.php
│ │ ├ ─ConfigController.class.php
│ ...

Its access format:

http://serverName/Home/User/UserType
http://serverName/Home/Admin/User

Setting up a multi-level controller requires setting configuration parameters, that is, setting the hierarchical level of the controller, for example, setting level 2 The controller layer of the directory is as follows:

'CONTROLLER_LEVEL' => 2,

The command space is like this;

        

         Copy after login
        
       

Instancing of multi-level controllers:

can be instantiated directly

// 实例化Home模块的User控制器 $User = new \Home\Controller\User\UserTypeController(); // 实例化Admin模块的Blog控制器 $Blog = new \Admin\Controller\Admin\UserController();
