php - $_POSTから配列データを抽出する

Question

2つのMYSQLテーブル「Piece」と「Order1」があります

PHPでは、この$ _POST配列内の各注文（およびその中の部分）をループして、データベースに保存したいと思います。

個々の注文を保存するためにwhileループを実行しようとしましたが、各注文の下にあるピースを取得できませんでした。多分これは行く方法ではないと思います。

誰かが私に例や提案をしてくれるなら、それは素晴らしいことです。

Answer 1

これを試して ：

   foreach ($_POST['order']['details'] as $detail)
   {
       foreach($detail['pieces'] as $pieces)
       {
          //store($pieces['piece_length']);
          //store($pieces['piece_width']);
          //store($pieces['piece_height']);
          //store($pieces['piece_unittype']);
          //store($pieces['piece_actualweight']);
          //store($pieces['piece_weighttype']);
       }
    }

Answer 2

使用する方が良いでしょう

 foreach($_POST['order']['details'] as $key=>$order)
 {
    if(is_array($order['pieces']) && $key=='pieces')
    {
      foreach($order['pieces']) as $pices)
      $insert[]=implode(',',$pices);//array for later insert,you should do necessary validation and should deal with mysql injection
    }

 }

Answer 3

これを試して

foreach($orders as $order)
{
   //store($order)

   $pieces = $order['pieces'];
   foreach($pieces as $a_pieces)
   {
      //store($a_pieces);
   }
}

Answer 4

array_walk_recursive（）関数を試してください
