laravel jump routing

Laravel is a popular PHP framework that provides many convenient functions and methods, allowing developers to quickly develop efficient and maintainable applications. In Laravel, routing is a very important concept that allows developers to define the URL of the application.

In Laravel, jump routing is a very common requirement, such as jumping to another page after the user logs in, jumping to another page after the form is submitted, etc. This article will introduce jump routes in Laravel and how to use them.

1. Jump to the named route

In Laravel, named route (Named Route) is a very convenient way to define routes. By defining a name for a route, we can use this name in code to generate a URL or jump to this route. The following is an example:

Route::get('user/profile', function () {
    //
})->name('profile');

Here, we define a route named "profile". When we need to jump to this route, we can use the following code:

return redirect()->route('profile');

This method accepts a route name as a parameter and returns a response that redirects to that route. If you want to pass parameters to the route, you can pass them in the second parameter, for example:

return redirect()->route('profile', ['id' => 1]);

Here we are passing a parameter named "id" to the route and its value is 1 . Then, in the target route, we can use code like the following to get this parameter:

Route::get('user/{id}', function ($id) {
    //
})->name('profile');

Here, we can use the $id variable to access the passed parameter.

2. Jump to the controller method

In Laravel, we can also define a controller method as the handler of the route, and then jump to this controller method. Here is an example:

Route::get('user/profile', 'UserController@showProfile');

Here, we define a controller method named "showProfile" as the handler for the route. When we need to jump to this controller method, we can use the following code:

return redirect()->action('UserController@showProfile', ['id' => 1]);

This method accepts a controller method name as a parameter, and then returns a response that redirects to the controller method. If you want to pass parameters to controller method you can pass them in second parameter like:

return redirect()->action('UserController@showProfile', ['id' => 1]);

Here we are passing a parameter named "id" to controller method which The value is 1. Then, in the target controller method, we can use code like the following to get this parameter:

public function showProfile($id)
{
    //
}

Here, we can use the $id variable to access the passed parameter.

3. Jump to URL

In Laravel, we can also jump directly to any URL without defining any route or controller method. Here is an example:

return redirect('user/profile');

Here we can directly pass the target URL to the redirect function and then return a response redirected to that URL.

If you need to pass parameters, you can use query string (Query String) parameters in the URL, for example:

return redirect('user/profile?id=1');

Here, we will use a query character named "id" The string parameter passed to the target URL has a value of 1. Then, in the target page, we can use code similar to the following to get this parameter:

$id = request('id');

Here, we use the request() helper function to get the query string parameter in the request.

Summary

In this article, we introduced jump routing in Laravel, including jumping to named routes, jumping to controller methods, and jumping to URLs. In actual development, these jump routes will be very useful, helping us quickly jump to the target page and improving development efficiency and user experience.
