php - laravel undefined variable : user

Question

作为序言，我已经完成了大部分与我的问题一致的答案，几乎我有一个 undefined variable为用户。

我希望能够在仪表板上显示注册用户，我之前使用过这段代码并且它有效但不适用于此应用程序。

Undefined variable: user (View: /Applications/MAMP/htdocs/eli/resources/views/dashboard.blade.php)

这是我的代码，

UserController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\User;
use App\Http\Requests;

class UserController extends Controller
{
    public function getWelcome()
    {

      return view('welcome');

    }

    public function getDashboard()
    {
        $users = User::all();

        return view('dashboard', compact('users'));
    }


    public function userSignUp(Request $request)
    {

        $this->validate($request, [
            'email' => 'required|email|unique:users',
            'first_name' => 'required|max:120',
            'password' => 'required|min:4'

        ]);

        $email = $request['email'];
        $first_name = $request['first_name'];
        $password = bcrypt($request['password']);

        $user = new User();
        $user->email = $email;
        $user->first_name = $first_name;
        $user->password = $password;

        $user->save();



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

    }
    public function postSignin(Request $request)
    {
        $remember = $request->input('remember_me');

        if(Auth::attempt(['email'=> $request['email'], 'password' => $request['password']], $remember )){
            return redirect()->route('dashboard');
        }

        return redirect()->back();
    }


}

dashboard.blade.php

@extends('layouts.layout')

@section('title')
Dashboard
@endsection

@section('content')
    <div class="container eli-main">
        <div class="row">
            <div class="col-md-6 col-md-12">


                      <h1>{{$user->username}}</h1>


            </div>
    </div>
@endsection

Answer 1

您正在将 $users 集合传递给 View ，因此如果您想要显示所有用户的姓名，则需要对其进行迭代:

@foreach ($users as $user)
    {{ $user->username }}
@endforeach

如果你想显示经过身份验证的用户的姓名，只需这样做:

{{ auth()->user()->username }}
