php - 选择数据并使用 where 和 where laravel 5.6

Question

我正在尝试创建 ( (Where and Where) OR (Where and Where) ) 经过大量搜索我发现了这个

  $last_transations = Transcationhistorique::where('sender_id', '=', $user_id)
                            ->where('receiver_id','=', $user_id)
                            ->orderBy('created_at', 'desc')
                            ->skip(3)
                            ->take(3)
                            ->get();

我得到一个空的结果

"last 3 transactions": []

如果您要搜索简单的 where 或 where 则使用(使用您的查询):

$last_transations = Transcationhistorique::where('sender_id', $user_id)
                    ->orWhere('receiver_id', $user_id)
                    ->orderBy('created_at', 'desc')->skip(3)->take(3)->get();

如果您正在搜索 where and where 然后使用(使用您的查询):

$last_transations = Transcationhistorique::where(['sender_id' => $user_id, 'receiver_id' => $user_id])
                    ->orderBy('created_at', 'desc')->skip(3)->take(3)->get();

如果您正在搜索 (where and where) OR (where and where) ，这有点复杂，您可以这样查询:

DB::table('users')
   ->where(['col1' => 'val1', 'col2' => 'val2'])
   ->orWhere(function ($query) {
         $query->where(['col3' => 'val3', 'col4' => 'val4']);
   })
   ->get();
