How to implement jump to another method in thinkphp

When developing using the PHP framework thinkphp, sometimes we need to jump from one method to another. This situation is very common in actual development. This article will introduce how to implement jumping to another method in thinkphp.

First of all, we need to understand the routing concept in thinkphp. thinkphp uses a routing mechanism to process requests. The routing mechanism is responsible for mapping user requests to corresponding controller methods.

In thinkphp, we can access the controller method through the URL address. The usual URL address format is:

http://<域名>/<控制器>/<方法>

For example, we can access the controller Index method through the following URL address. hello:

http://example.com/index/hello

In thinkphp, to jump to another method, we can use the redirect function. The function of this function is to redirect the request to the specified URL address or routing address.

What needs to be noted here is that if we want to jump to another method of the current controller, we can directly use the name of the controller method as the routing address. For example, there is a method test in the controller Index, we can redirect the request to the method through the following code:

$this->redirect('test');

When we use $this->redirect('test'), thinkphp will automatically Use test as the routing address, and then execute the method test of the controller Index.

If we want to jump to other controller methods, we need to use the complete routing address. For example, to jump to the login method of the controller User, we can use the following code:

$this->redirect('user/login');

Here user is the controller name and login is the method name. thinkphp will execute the corresponding controller method according to the routing address.

In addition to specifying the complete routing address, we can also use an array to define the routing address. For example, to jump to the method list of the controller User, we can use the following code:

$this->redirect(['user/list']);

Using an array can define the routing address more flexibly and pass more parameter information.

In actual development, it is easy for us to need to pass parameters to jump methods. In thinkphp, we can use variables to pass parameters. For example, if we want to jump to the method detail of the controller User and bring the parameter id=1, we can use the following code:

$id = 1;
$this->redirect('user/detail', ['id' => $id]);

In the above code, we first define an $id variable, which The variable has a value of 1. Then we use $this->redirect('user/detail', ['id' => $id]) to redirect the request to the method detail of the controller User, and pass a parameter id whose value is a variable The value of $id.

When jumping, we can also specify the jumping method. thinkphp supports the following jump methods:

• Page jump (default): Using the 301 or 302 status code, the browser will automatically jump to the specified URL address.
• AJAX jump: Use JSON format to return the jump address, and the front end will jump by itself.
• Redirect: Use HTTP status code 302 to redirect the request to the specified URL address on the server side.

If you do not specify a jump method, thinkphp will use page jump by default.

Summary:

In thinkphp, we can jump to another method through the redirect function. We can use the name of the controller method as the routing address, or we can use the complete routing address. When jumping, we can also pass parameters and specify the jump method. I wish everyone can successfully jump to another method in thinkphp development.
