Laravel，将数组中的多个变量存储到数据库中

Question

我不确定问题标题是否正确，但在下面的示例中我想做的很清楚我有 3 个 arrays 并且我想将数据存储在一个表中

表结构是这样的

表名：tour_transsports

ID

transport_id

运输轨道

transport_note

arrays 来自刀片

  "transport_id" => array:2 [
    1 => "1"
    5 => "5"
  ]
  
  
  "transport_track" => array:3 [
    1 => " from airport to the hotel"
    3 => null
    5 => " be ready at 4:pm"
  ]
  
  
  "transport_note" => array:3 [
    1 => "from hotel to the beach"
    3 => null
    5 => " bring ur swiming suite"
  ]

所以你看到id是1和5所以我想在这里存储两行

id = 1,transport_id = 1, transport_track = 从机场到酒店, transport_note = 4:pm 准备好

id = 2,transport_id = 5, transport_track = 从酒店到海滩, transport_note = 带上你的游泳套房

我试图这样做，但无法正确

 if(!empty($request->transport_id))
     {
       foreach ($request->transport_id as $key => $transport_id) {
         
         foreach ($request->transport_track as $key => $track) {

           foreach ($request->transport_note as $key => $transport_note) {
       

        TourTransport::create([
        'transport_id' =>$transport_id,
        'transport_track' =>$track[$transport_id],
        'transport_note' =>$transport_note[$transport_id]
                               ]);

              }
         
          }
       }
     }

Answer 1

您可以使用此代码来实现您的结果：

$data = $request->only('transport_id', 'transport_track', 'transport_note');

foreach ($data['transport_id'] as $key => $transportId) {
    TourTransport::create([
        'transport_id' => $transportId,
        'transport_track' => $data['transport_track'][$key],
        'transport_note' => $data['transport_note'][$key],
    ]);
}

现在 $results 包含所需的数据。 然而，更好的解决方案可能是配置您的 html 表单以在单个数组条目中发送相关数据，例如：

<input type="text" name="transports[0][transport_id]">
<input type="text" name="transports[0][transport_track]">
<input type="text" name="transports[0][transport_note]">

<input type="text" name="transports[1][transport_id]">
<input type="text" name="transports[1][transport_track]">
<input type="text" name="transports[1][transport_note]">

您还可以使用 Javascript/php 循环来生成表单输入。 然后您将在服务器端以格式良好的结构接收表单数据，例如：

"transports" => array:2 [
   [
       'transport_id' => 1,
       'transport_track' => 'from airport to the hotel',
       'transport_note' => 'be ready at 4:pm',
   ],
   [
       'transport_id' => 5,
       'transport_track' => 'from hotel to the beach',
       'transport_note' => ' bring ur swiming suite',
   ],
]
