Question

控制器：

$users = DB::table('users')
        ->join('uploads', 'users.id', '=', 'uploads.user_id')
        ->select(DB::raw('users.*, COUNT(*) AS total_uploads'))
        ->orderby('total_uploads', 'desc')
        ->groupby('users.id')
        ->take(5)
        ->get();

查看：

<?php $i = 1 ?>
@foreach($users as $user)
<tr>
    <td>{{ $i }}</td>
    <td><a href="user/{{ $user->username }}">{{ $user->username }}</a></td>
    <td>{{ $user->total_uploads }}</td>
</tr>
<?php $i++ ?>
@endforeach

预期输出：

 1  John  99
 2  Mary  78
 3  Jill  57
 3  Bill  57
 5  Hans  56

如何修改此项以说明关系？

Answer 1

试试这个：

<?php $i = 0;
      $last_count = null;
?>
@foreach($users as $user)
<?php if($user->total_uploads != $last_count) $i++; ?>
<tr>
    <td>{{ $i }}</td>
    <td><a href="user/{{ $user->username }}">{{ $user->username }}</a></td>
    <td>{{ $user->total_uploads }}</td>
</tr>
<?php $last_count = $user->total_uploads; ?>
@endforeach

只有当前用户total_uploads与上一位用户的total_uploads不同时，该计数器才会递增。
