Question

我在laravel 5.1上工作。我一直想着如何将我的2个数组输入存储到DB上的同一行。我只知道如何存储一个数组。

$amount[] = $request->amount;
$receipt[] = $request->receipt;

foreach ($amount as $key => $value) {
  $reimbursement_item = ReimbursementItem::create([
     'user_id' => $user->id,
　　　'amount' => $value,
  ]);
}

DB structure and aspect result:
id  user_id  amount  receipt
--  -------  ------  --------------
1    32      40.00   /images/r1.jpg
2    24      60.00   /images/r2.jpg

如果您可以更新您的请求对象结构，那就更好了，就像应该有一个数组，并且每个数组索引都有值和收据的值而不是单个数量和收据数组

$data[] = $request->data;
foreach ($data as $key => $value) {
  $reimbursement_item = ReimbursementItem::create([
     'user_id' => $user->id,
　　　'amount' => $value['amount'],
　　　'receipt' => $value['receipt']
  ]);
}

另一种方法是，如果每个数组$amount和$receipt的长度相同且值正确，您也可以在单循环中更新数据，如

foreach ($amount as $key => $value) {
  $reimbursement_item = ReimbursementItem::create([
     'user_id' => $user->id,
　　　'amount' => $value,
      'receipt' => (isset($receipt[$key]))? $receipt[$key]: null
  ]);
}
