Question

我目前正在开发一个数据库，我希望将order_ID放入两个表中。这有效，但我遇到的问题是循环只迭代一次。如果有人可以提供帮助并解释我出错的地方，我们将不胜感激。

session_start();
echo $_SESSION['shop_id'];
$shopid = $_SESSION['shop_id'];
$username = $_SESSION['username'];
$con = mysqli_connect('localhost', 'root', '', 'aurora');
if (!isset($con)) {
    echo "Connection to Aurora System failed.";
}

if (isset($_POST['items'])) {
    echo "True";
} else {
    echo "false";
}

$valid = true;
$date =  date('l jS \of F Y h:i:s A');
$sql2 = "INSERT INTO orders_new (user_submitted, order_date, customer_ID) VALUES ('$username', '$date', '$shopid')";
if ($valid == true) {
    $ordersubmit2 = mysqli_query($con, $sql2);
    echo "Success!";
} 

$count = $_POST['items'];
for ($i = 1; $i <= $count; $i++) {
    $idinsert = mysqli_insert_id($con);
    $product = $_POST['product'.$i];
    $nicotine = $_POST['nicotine'.$i];
    $qty = $_POST['qty'.$i];
    echo $product;
    $sql = "INSERT INTO orders_detail (orders_id ,product, variant, quantity) VALUES ('$idinsert', '".$product."', '".$nicotine."', '".$qty."')";
    $ordersubmit = mysqli_query($con, $sql);
}

Answer 1

是我自己的错，order_id是主键，因此循环因仅允许唯一值而停止。

PHP - For循环只写一个提交到MySql
