Let's talk about how thinkphp controllers call each other's methods

ThinkPHP is an excellent PHP framework that provides many convenient functions to assist developers in quickly building Web applications. Among them, the controller is one of the most important parts of the framework. It is responsible for receiving user requests, processing data and returning response results. In controllers, we usually need to call different methods to each other to achieve more complex functions. This article will introduce how to call methods in ThinkPHP controllers.

1. Calling methods to each other in controllers

In ThinkPHP, we can call different methods to each other in controllers to avoid code duplication and improve code reuse Rate. Here is an example:

<?php namespace app\index\controller;

use think\Controller;

class User extends Controller
{
    public function login(){
        // 处理登录逻辑
    }

    public function update(){
        // 处理用户信息更新逻辑
    }

    public function register(){
        $this->login(); // 调用login方法
        $this->update(); // 调用update方法
        // 处理注册逻辑
    }
}

In the above example, we called login() and update()# in the register() method ##method. We can use the $this keyword in the controller class to call methods in the same controller.

Parameter passing in the called method

When calling mutual calling methods, we may need to pass parameters to the called method. In ThinkPHP, we can use the parameter passing method of the controller class:

$this->param(). Here is an example:

<?php namespace app\index\controller;

use think\Controller;

class User extends Controller
{
    public function login($username, $password){
        // 处理登录逻辑
    }

    public function register(){
        $username = &#39;test&#39;;
        $password = &#39;123456&#39;;
        
        $this->login($username, $password); // 调用login方法, 传递参数
        // 处理注册逻辑
    }
}

In the above example, we called the

login() method in the register() method and passed There are two parameters, $username and $password. In the called method, we can use $this->param() to get the passed parameter value.

Call methods in other controllers

In addition to calling methods to each other within the same controller, we can also call methods in other controllers. In ThinkPHP, we can use the

action() method to achieve this. Here is an example:

<?php namespace app\index\controller;

use think\Controller;

class User extends Controller
{
    public function login($username, $password){
        // 处理登录逻辑
    }

    public function update($username){
        // 根据传递的用户名更新用户信息
    }
}

class UserController extends Controller
{
    public function index(){
        $user = new User();
        $user->login('test', '123456'); // 调用User控制器中的login方法
        $user->update('test'); // 调用User控制器中的update方法
    }
}

In the above example, we called

login()# in the UserController controller ## and update() methods. We create a User object, and then use $user->login() and $user->update() to call the corresponding methods. In short, it is very easy to call different controllers and different methods in ThinkPHP. Using controllers to call methods between each other can greatly improve code reuse and reduce code duplication. So, we should use this feature as much as possible to optimize our code and make our application more robust and reliable.
