How to implement cross-module jump in thinkphp5

thinkphp5 is a lightweight and efficient PHP development framework that supports cross-module jumps. During the development process, we sometimes need to jump pages through different modules, which requires the use of the cross-module jump function.

Cross-module jumps can make applications more modular and improve code reusability. The following will introduce the method of implementing cross-module jump in thinkphp5.

1. Create the controller of the target module

First make sure that the target module exists and has a controller. If there is no controller, you need to create it first. Creating a controller is the same as creating a controller in the default module.

For example, we have a default module and an admin module, and now we need to jump from the default module to the Index controller in the admin module, we need to create an Index controller.

Create a new Index.php file in the controller directory of the admin module, and add the following code to the file:

<?php namespace app\admin\controller;
use think\Controller;
class Index extends Controller
{
    public function index()
    {
        return "hello, welcome to admin module";
    }
}

There is only one index method in the Index controller here, which is used to return "hello , welcome to admin module" this string.

2. Cross-module jump in the controller

Use the url function in the controller of the default module and specify the cross-module route to achieve cross-module jump.

In the index method of the Index controller of the default module, jump through the following code:

return $this->redirect('admin/Index/index');

The redirect method is used here and the cross-module jump route is set.

The redirect method is the encapsulation method of thinkphp5 framework and is used for page jump. Its parameters can be the module name, controller name and method name, or the complete URL address.

In this example, the jump target is the index method of the Index controller in the admin module, so the jump route is "admin/Index/index".

3. Use routing to jump across modules

thinkphp5 provides a powerful routing function that can easily achieve cross-module jumps. Use the "/" delimiter in the route to achieve cross-module jumps.

Add the following code to the routing file route.php of the default module:

// 跨模块访问admin模块
Route::get('admin', 'admin/Index/index');

A route named "admin" is defined here, and the route points to the index of the Index controller of the admin module method. When jumping in the controller, you only need to use the routing name "admin", as shown below:

return $this->redirect('admin');

In this way, you can jump from the default module to the admin module Index controller.

Summary

thinkphp5 has a powerful cross-module jump function, which can make applications clearer and improve development efficiency. Through the two methods of cross-module jump in the controller and cross-module jump in the routing, we can make the application more modular and clear, realize code reuse, and improve development efficiency.
