laravel jump page passing id

In Laravel, it is a very common requirement to jump to the page and pass parameters. Among them, passing the ID as a parameter to the next page is a very common requirement. This article will explain how to implement jump pages and pass ID parameters in Laravel.

The first method: using URL to pass parameters

Using URL to pass parameters is one of the most commonly used methods of passing parameters. It allows us to add parameters that need to be passed in the URL, and then use them in the next page by getting the URL parameters. The following are the specific implementation steps:

First, get the parameters in the controller and splice the URL:

public function jump(Request $request) { $id = $request->input('id'); $url = '/detail?id=' . $id; return redirect($url); }

In the above controller method, we pass$request->input(' id')Get the passed ID and splice it into the URL. Then use theredirect($url)method to jump. Let's take a look at how to get the ID parameter on the next page.

public function detail(Request $request) { $id = $request->input('id'); // ... }

In the next processing page, we also use the$request->input('id')method to obtain the ID parameter passed in the URL, and then use this parameter to proceed related operations.

Second method: Use Session to pass parameters

Another common method of passing parameters is to use Session. This method can pass data without exposing parameter information.

First, store the parameters into the Session in the controller:

public function jump(Request $request) { $id = $request->input('id'); $request->session()->put('id', $id); return redirect('/detail'); }

In the above code, we pass$request->session()->put('id ', $id)method stores the passed ID into the Session, and then uses theredirect('/detail')method to jump.

Next, get the ID parameter through Session in the next page:

public function detail(Request $request) { $id = $request->session()->get('id'); // ... }

In the next processing page, we also use$request->session()->get The ('id')method obtains the ID parameter stored in the Session, and then you can use this parameter to perform related operations.

Summary

The above are two commonly used methods to jump to pages and pass ID parameters in Laravel. Whether you use URL to pass parameters or Session to pass parameters, you can quickly and easily achieve this requirement. When using these methods, be sure to pay attention to the security of parameters to avoid malicious tampering of parameters.
