foreach Laravel 的多个 id - PHP 问题

Question

我有一个搜索功能，我需要添加id 的帖子（来自表opinions，列id）。在我看来，我已经拥有subject，并且我使用$user->subject 从数据库中获取它，但是在$user->id，我得到的是用户的ID，而不是帖子的ID。所以，我需要正确地获取数据。我需要根据主题获取帖子的 ID。

现在，我创建了一个返回类似内容的新变量：

$user = Opinion::where ( 'subject', 'LIKE', '%' . $q . '%' )
                     ->join('role_users' , 'role_users.user_id', '=', 'opinions.user_id')
                        ->join('roles' , 'roles.id', '=', 'role_users.role_id')
                        ->join('users', 'users.id', '=', 'opinions.user_id')
                        ->orWhere ( 'opinions.user_id', 'LIKE', '%' . $q . '%' )
                        ->orWhere ( 'opinions.id', '=', 'opinions.subject')
                        ->orWhere('opinions.category_id' ,'=', $category->id)
                        ->orWhere ( 'opinions.user_id', '=', 'users.username')
                        ->get ();
$topic_id = Opinion::select('id', 'subject')
        ->get();


Collection {#883 ▼
  #items: array:20 [▼
    0 => Opinion {#873 ▶}
    1 => Opinion {#851 ▼
      #table: "opinions"
      +timestamps: false
      #fillable: array:10 [▶]
      #connection: null
      #primaryKey: "id"
      #keyType: "int"
      #perPage: 15
      +incrementing: true
      #attributes: array:2 [▼
        "id" => "2"
        "subject" => "4 Ways We Can Avoid Workplace Burnout"
      ]

这是我的看法：

<?php $count_event = 1; ?>
        @foreach($details as $user)
    @if($count_event == 1)

      $match = '';
      $str = $user->information;
      $start = "<iframe src='";
      $end = "' width='100%' height='281'></iframe>";

      $pattern = sprintf(
        '/%s(.+?)%s/ims',
        preg_quote($start, '/'), preg_quote($end, '/')
        );

      if (preg_match($pattern, $str, $matches)) {
        list(, $match) = $matches;
      }
    ?>
    @if(isset($match) && $match != '')
      <iframe src="{{ $match }}" width='100%' height='258'></iframe>
    @elseif(isset($video[1]))
      <iframe src="{{ $video[1] }}" width='100%' height='258'></iframe>
    @else

      <?php preg_match('/<img.+src=[\'"](?P<src>.+?)[\'"].*>/i', $user->information, $image); ?>

我从意见中得到每一篇文章。但是现在，如果我将它与@foreach 一起使用，我会从我的页面上获得所有记录（id + 主题），关于每个主题：https://imgur.com/a/ROuxpwC。

那么，如何正确分配每个主题的id？

您可以在查询构建器中添加选择功能来获取这样的意见 id

$user = Opinion::where ( 'subject', 'LIKE', '%' . $q . '%' )
                     ->join('role_users' , 'role_users.user_id', '=', 'opinions.user_id')
                        ->join('roles' , 'roles.id', '=', 'role_users.role_id')
                        ->join('users', 'users.id', '=', 'opinions.user_id')
                        ->orWhere ( 'opinions.user_id', 'LIKE', '%' . $q . '%' )
                        ->orWhere ( 'opinions.id', '=', 'opinions.subject')
                        ->orWhere('opinions.category_id' ,'=', $category->id)
                        ->orWhere ( 'opinions.user_id', '=', 'users.username')
                        ->select('opinions.id as id','subject')
                        ->get ();
