laravel 如何使用变量通过高级连接子句连接三个表

Question

Larvel 对多个表和值的内部联接有疑问。我确实在 laravel.

中构建了我的代码

$clients = clients::leftjoin('clients_payment_type','clients_topup', function($join) {
        $join->on('clients_payment_type.user_id', '=', 'clients.id') AND
        $join->on('clients_topup.user_id', '=', 'clients.id');
      })->where('clients.reference_id','=',$reference_id)->get();

Answer 1

试试这个：

$clients = clients::leftjoin('clients_payment_type','clients_topup')
->join('clients','clients_payment_type.user_id', '=', 'clients.id')
->join('client_toup','clients.id', '=', 'clients_topup.user_id')
->where('clients.reference_id','=',$reference_id)
->get();

此致

Answer 2

有效答案

  $clients1 = DB::table('clients')
          ->leftjoin('clients_payment_type','clients_payment_type.user_id', '=', 'clients.id')
          ->leftjoin('clients_topup', 'clients_topup.user_id', '=', 'clients.id')
          ->where('clients.reference_id','=',$reference_id)
          ->get();
