php - 试图获取非对象 Laravel 5.4 的属性

Question

嗨，伙计，我总是从 Laravel 5.4 中收到错误。我正在创建一个成员列表...但是当我使用@foreach 时它说

ErrorException in 6163a8b030c7474bc8eaad359ab99eb61ebdb127.php line 38:
Trying to get property of non-object (View: E:\wamp64\www\gplspring2017\resources\views\admin\memberlist.blade.php)

这是我的 Controller

public function listmember(Request $request, $idteam)
{
    $teams = DB::table('gpl_team')->where('gpl_team_id', $idteam)->first();
    $count = count($teams);

    if (!$count) {
        return redirect('404');
    } else {
        return view('/admin/memberlist', ['team' => $teams]);
    }
}

这是我的 View 代码:

<table class="table table-striped">
    <tr>
        <td style="width:15%;"></td>
        <td style="width:25%;">Summoners Name</td>
        <td style="width:25%;">Name</td>
        <td style="width:25%;">Role</td>
        <td style="width:10%;"></td>
    </tr>
    <?php
    $qmember = DB::table('team_member')->where('gpl_team_id', $team->gpl_team_id)->first();

    $counting = count($qmember);

    ?>
    @if (! $counting)
    <tr>
        <td colspan="4"> No Recored! </td>
    </tr>
    @else
    @foreach($qmember as $get_member)
    <tr>
        <td><img src="{{ $get_member->member_pic }}" /></td>
        <td></td>
        <td></td>
        <td></td>
        <td>
            <a href="" data-toggle="tooltip" title="Edit Team"><div class="glyphicon glyphicon-pencil"></div></a> |
            <a href="" data-toggle="tooltip" title="Delete Team"><div class="glyphicon glyphicon-trash"></div></a>
        </td>
    </tr>
    @endforeach
    @endif
</table>

当我删除 foreach 时，代码可以正常工作..但我尝试添加 @foreach($qmember as $get_member) 它不再工作了...

检查这一行:

$qmember = DB::table('team_member')->where('gpl_team_id', $team->gpl_team_id)->first();

当您使用 first() 时，它不会返回 Std Class 对象。如果需要，请使用 get()
