即使用户未登录，如何获取用户（经过身份验证的）信息？

Question

I want to show user information publicly from built-in users table in Laravel. More specifically, Anyone can see user information( name , email , username ) without logged in. I've used these in blade file:

{{ Auth::user()->name }}
{{ Auth::user()->email }}

But it only works when user logged in otherwise shows errors. Even I've used ELOQUENT in controller and have passed $user object with by view . I'm attaching images so that you can understand my problem. This is my PagesController file

<?php

namespace App\Http\Controllers;
use App\Post;
use App\User;

class PagesController extends Controller{
    public function getIndex(){
        $posts=Post::orderBy('id', 'DESC')->paginate(4);
        $user=User::all();
        return view('pages.welcome')->withPosts($posts)->withUser($user);
    }
}

And this is my welcome.blade.php file

<div class="panel-heading">{{ ucwords($user->name) }}</div>

Answer 1

Auth::user takes information of the currently authenticated user. So it will o ly work when the user is logged in.

Answer 2

Auth::user() returns the current authenticated user or null for guest users. So if you call Auth::user()->name on a guest user it will display the error trying to get property of non-object because its trying to get name from a null object

You can use something like this in your blade:

@if(Auth::check())
    User: {{ Auth::user()->name }}
    Email: {{ Auth::user()->email }}
@else
    User: Guest
@endif

If you want to display all users, use the following in your blade:

@foreach(\App\User::all() as $user)
    User: {{ $user->name }}
    Email: {{ $user->email }}
@endforeach
