Question

如何显示新插入的条目？每当我尝试同时提交2个或更多条目，并将其显示在我的刀片上时，它只会显示我插入的最后一个条目。这里似乎有什么问题？

Controller.php这样

     public function onewayflightshow()

        foreach ($show as $user)
        {  
            $adultFee = ($user->fare)*$adult;
            /*------------------------Child Fee------------------------*/

你应该改变：

  for( $i=0; $i < $c; ++$i ) {
    $reserve = new Reserves;
    // ...
    $reserve->payment = $payment;

    $reserve->save();  

}

成：

  $resIds = [];
  for( $i=0; $i < $c; ++$i ) {
    $reserve = new Reserves;
    // ...
    $reserve->payment = $payment;

    $reserve->save();  
    $resIds[] = $reserve->id;

}

并改变：

$res = DB::table('reserves')->where('id', '=' ,$reserves)->get();

成：

$res = DB::table('reserves')->whereIn('id', $resIds)->get();
