使用PHP將多維數組插入mysql

Question

我試圖從動態jQuery表單中插入此多維數組，但不確定如何解決此問題。 打印時，數組顯示如下：

[item] => Array ( 
    [1] => Array ( 
        [unit] => service 
        [qty] => 3 
        [description] => Description 1 
        [price] => $ 33 
        [tax] => 60 % 
        [total] => $ 158.40
    ) 
    [2] => Array ( 
        [unit] => hours 
        [qty] => 74 
        [description] => Description 2 
        [tax] => 3 % 
        [total] => $ 3,429.90 ) 
    [3] => Array ( 
        [unit] => days 
        [qty] => 67 
        [description] => Description 3 
        [tax] => 6 % 
        [total] => $ 284.08 ) 
    [4] => Array ( 
        [unit] => product 
        [qty] => 72 
        [description] => Description 4 
        [tax] => 34 % 
        [total] => $ 3,183.84 
    ) 
) 

我用它作為我的每條陳述，但沒有奏效：

$returnedData = $_POST['item'];

      foreach($returnedData as $data) {
                $unit = $data['unit'];
                $qty = $data['qty'];
                $description = $data['description'];
                $tax = $data['tax'];
                $price = $data['price'];
                $subtotal = $data['total'];
      }

    $insert_items = mysqli_query($connect_db,"INSERT INTO items (invoice_id, date, unit, qty, description, tax, price, subtotal) VALUES ($invoice, $todays_date, $unit, $qty, $description, $tax, $price, $subtotal)");

有人知道如何捕獲所有數據嗎？ 每個循環都可以嗎？

Answer 1

可能會幫到您。 因為這是一個多維數組，所以您可以再應用一個循環來獲取值，並在第一個循環之后編寫INSERT查詢

$returnedData = $_POST['item'];

foreach($returnedData as $value=>$data) 
{
        $unit = $data['unit'];
        $qty = $data['qty'];
        $description = $data['description'];
        $tax = $data['tax'];
        $price = $data['price'];
        $subtotal = $data['total'];

    $insert_items = mysqli_query($connect_db,"INSERT INTO items 
    (invoice_id, date, unit, qty, description, tax, price, subtotal) 
    VALUES 
    ($invoice, $todays_date, $unit, $qty, $description, $tax, $price, $subtotal)");
}
