使用redirect() 輔助函數(shù)可實(shí)現(xiàn)Laravel 控制器中的重定向，如redirect()->route('home') 跳轉(zhuǎn)到命名路由，redirect('/dashboard') 跳轉(zhuǎn)到指定URL，redirect()->back() 返回上一頁(yè)，結(jié)合withInput() 保留表單數(shù)據(jù)，with() 傳遞會(huì)話消息，推薦使用命名路由以提高可維護(hù)性。
To redirect a user in a Laravel controller, you can use Laravel's built-in redirect helper or the RedirectResponse class. This is commonly done after form submissions, authentication, or when enforcing access control.
Using the redirect() Helper
The most common and convenient way to redirect is using the global redirect() helper function.
-
Redirect to a named route:
return redirect()->route('home'); -
Redirect to a URL:
return redirect('/dashboard'); -
Redirect back to the previous page:
return redirect()->back(); -
Redirect with input (eg, for form resubmission):
return redirect()->back()->withInput(); -
Redirect with a session message:
return redirect()->route('profile')->with('status', 'Profile updated!');
Using Redirect Facade
If you prefer using facades, import Redirect at the top of your controller:
use Illuminate\Support\Facades\Redirect;return Redirect::to('/dashboard');
return Redirect::route('profile');
return Redirect::back();
This achieves the same result as the helper function but uses facade syntax.
Returning Redirect Responses from Methods
You can also return redirect responses directly in controller methods, especially in form handling:
public function store(Request $request){
// Save data...
return redirect()->route('posts.index')
->with('success', 'Post created successfully.');
}
The with() method flashes a session message that can be displayed on the next request.
Basically, just pick the redirect style that fits your flow—named routes are recommended for maintainability. Use with() to pass status messages, and back() for returning users after validation fails.
