Laravel：未定义变量：请求

Question

我无法找到问题。它在哪里？ “未定义的变量：要求”

public function login() 
{ 
    // Validate the form data 
    $this->validate($request, [ 
    'email' => 'required|email', 
    'passwort' => 'required|min:6' 
    ]); 

    // Attempt to log the user in 
    if (Auth::guard('admin')->attempt(['email' => $request->email, 'passwort' => $request->passwort], $remember)) { 
    // if successful, then redirect to their intended location 
    return redirect()->intended(roue('admin.dashboard')); 
    } 

    // if unsuccessful, then redirect back to the login with the form data 
    return redirect()->back()->withInput($request->only('email', 'remember')); 
} 

Answer 1

你需要注入Request对象：

public function login(Request $request) 

此外，该行添加到您的类的顶部：

use Illuminate\Http\Request; 

或者，您也可以只需在代码中使用request()而不是$request。

Answer 2

您尚未定义'请求'变量，但您在代码中使用了它。

编辑代码

public function login(Request $request) 
{ 
    // Validate the form data 
    $this->validate($request, [ 
    'email' => 'required|email', 
    'passwort' => 'required|min:6' 
    ]); 

    // Attempt to log the user in 
    if (Auth::guard('admin')->attempt(['email' => $request->email, 'passwort' => $request->passwort], $remember)) { 
    // if successful, then redirect to their intended location 
    return redirect()->intended(roue('admin.dashboard')); 
    } 

    // if unsuccessful, then redirect back to the login with the form data 
    return redirect()->back()->withInput($request->only('email', 'remember')); 
} 

此外，该行添加到您的类的顶部：

use Illuminate\Http\Request;
