php - 我有这个 Eloquent 文件，但我收到 undefined variable

Question

我想从我的数据库中获取一个表，我有来自 eloquent laravel 的这些文件，但我不知道为什么我收到 $user undefined 变量。我非常需要你的帮助，因为我不知道该怎么做才能完成我的项目。我需要 role_users 表、user_id 和 role_id 列。

编辑:这是我的名为“Events”的表格 /image/zk6We.jpg

“if”函数应该像这样工作......

@if(...role_id == 1)
<i class="icon-user"></i>
@else
<i class="icon-trophy"></i>

角色.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Role extends Model
{
    // protected $fillable = [
    //     'name', 'display_name', 'description',
    // ];
   protected $table = "roles";

    public function user()
    {
        return $this->belongsToMany('App\User','role_users','role_id','user_id');
    }
}

我的观点

                            <ul class="list-inline">

                                    <li style="font-style: normal !important"> 
@if( in_array("Organizations", $event->user->roles->pluck('role') )
    <i class="fa fa-building-o"></i>
@else
    <i class="icon-user"></i> 
@endif


                <a style="margin-left: 2px" href="{{ url('') }}/{{ $event->user->username }}">{{ $event->user->username }}</a></li>
                                    <li style="font-style: normal !important"><i style="margin-right: 3px" class="icon-hotel-restaurant-183 u-line-icon-pro fa-"></i> <a href="{{ url('view-all-event') }}">Event</li>

                                    <li style="font-style: normal !important"><i style="margin-right: 3px" class="icon-notebook fa-"></i> <a href="{{ url('topic') }}/{{ $event->category->category_url  }}">{{ $event->category->category }}</a></li>
                                                                    </ul>
@endforeach

In this case I receive this error:Undefined variable: user (View: /var/www/clients/client1/web2/web/resources/views/event/view_all_event.blade.php)

Event.php

    }

    public function role()
    {
        return $this->belongsToMany('App\Role','role_users','user_id','role_id');

    }

    public function country()
    {

        return $this->belongsTo('App\Country','country','id');
    }

    public function user_participant()
    {
        return $this->belongsToMany('App\User','events_participants','event_id','user_id');
    }

    {
        return $this->belongsToMany('App\ParticipantType','events_participants','event_id','participant_type');

        $collection = new Collection($items);

        //Define how many items we want to be visible in each page
        $perPage = $perPage;

        //Slice the collection to get the items to display in current page
        $currentPageSearchResults = $collection->slice(($currentPage * $perPage)- $perPage, $perPage)->all();

        //Create our paginator and pass it to the view
        $paginatedSearchResults = new LengthAwarePaginator($currentPageSearchResults, count($collection), $perPage);

       return $paginatedSearchResults;
    }
}

我猜 Event.php 适用于我的页面 ( view-all-event )。

Answer 1

使用

<li style="font-style: normal !important"> 
@if( in_array("Organizations", $event->user->roles->pluck('role') )
    <i class="fa fa-building-o"></i>
@else
    <i class="icon-user"></i> 
@endif
</li>

要检查用户是否具有组织角色，如果您已创建角色关系来关联用户和角色。
