php - 从 $_POST 中提取数组数据

Question

我有两个 MYSQL 表 'Piece' 和 'Order1'

在 PHP 中，我想遍历 $_POST 数组中的每个订单（以及其中的部分）并将其存储在我的数据库中。

我试图做一个while循环来存储每个单独的订单，但无法获取每个订单下的碎片。我在想也许这不是要走的路。

如果有人给我一个例子或建议，那就太好了。

    [order] => Array
            (
                [details] => Array
                    (
                        [0] => Array
                            (
                                [order1_itemcode] => 
                                [order1_description] => 
                                [order1_itemprice] => 
                                [order1_packagetype] => 0
                                [pieces] => Array
                                    (

Answer 1

尝试这个 ：

   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

试试array_walk_recursive()函数

Answer 3

使用会更好

 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 4

尝试这个

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

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