如何在用戶登錄後顯示用戶名？

Question

我很難嘗試顯示它登錄的用戶的名字或電子郵件。我沒有收到任何顯示。到目前爲止，我可以使用正確的憑據登錄，但無法顯示名稱。有人能告訴我我做錯了什麼嗎？我會非常感激。

登錄查看：

@extends('main') 

@section ('login') 

<div class = "row"> 
    <div class="col-md-6"> 
     <h2>Log In </h2> 
     <form action="{{route('signin')}}" method="post"> 
      <div class = "form-group"> 
       <label for="email">Please enter email address</label> 
       <input class="form-control" type="text" name="email" id="email"> 
      </div> 
      <div class="form-group"> 
       <label for="password"> Please enter the password</label> 
       <input class="form-control" type="password" name="password" id="password"> 
      </div> 
      <button type="submit" class="btn btn-primary">Submit</button> 
      <input type="hidden" name="_token" value="{{Session::token() }}"> 
     </form> 
    </div> 
</div> 


@endsection

use Illuminate\Http\Request; 
use App\Http\Requests; 
use DB;

用戶模型：

<?php 

namespace App; 

use Illuminate\Notifications\Notifiable; 

use Illuminate\Database\Eloquent\Model; 
use Illuminate\Foundation\Auth\User as Authenticatable; 

class User extends Authenticatable 
{ 
    use Notifiable; 

    /** 
    * The attributes that are mass assignable. 
    * 
    * @var array 
    */ 
    protected $table = 'users'; 
    protected $fillable = [ 
     'iduser', 'first_name', 'middle_name', 'last_name', 'address', 'email', 'phone', 'position', 'password', 
    ]; 

    /** 
    * The attributes that should be hidden for arrays. 
    * 
    * @var array 
    */ 
    protected $hidden = [ 
     'password', 'remember_token', 
    ]; 
} 

Answer 1

嘗試使用這個顯示的名字：

auth()->user()->first_name 

另外，我建議你改變iduser回id，因爲Laravel使用id作爲主鍵用戶模型。

Answer 2

在登錄視圖中將input type="hidden" name="_token"替換爲：{{ csrf_token() }}。

也改變{{ \Auth::user()->iduser}}到{{ Auth::user()->first_name }}

Answer 3

只要寫你想要的用戶名來打印記錄下面的代碼。

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

或

{{ Auth::user()->Your-Desire-FieldName-That-is-Available-At-User-Table }} 

或

dd(Auth::user()) 

然後看到的輸出，並使用密鑰回聲。

Answer 4

要避免遇到任何錯誤，當用戶未認證，得到了用戶的屬性是這樣的：

{{ Auth::user() ? Auth::user()->name: ''}}或{{ Auth::check() ? Auth::user()->name : ''}}

首先檢查，如果用戶進行身份驗證，然後獲得屬性「名」。這樣，當用戶沒有通過身份驗證/登錄時，您將不會收到任何錯誤，如Trying to get property of non-object
