Question

我正在尝试通过foreach循环获取购物车数组。我可以成功获取数组项，当我echo时，它会显示正确的值。但是当我对我的数据库表中输入的每个项目应用insert查询时，它不会插入任何内容，但它会显示成功。我有4个名为：

的表

客户 - ＆gt;序列primary，姓名，电子邮件，密码，地址，电话，城市
产品 - ＆gt; productid primary，名称，描述，图片，价格
订单 - ＆gt;序列primary，日期，customerid foreign key
order_detail - ＆gt; orderid，productid，数量，价格，颜色，尺寸

代码

if (isset($_SESSION['login_email'])) {
    $email = $_SESSION['login_email'];
    //Insert values in order table. This works correctly!!
    $query = mysqli_query($con, "SELECT serial FROM customers WHERE email = '$email'");
    while ($row = mysqli_fetch_array($query, MYSQLI_ASSOC)) {
        $cust_id = $row['serial'];
        $date = date('Y-m-d');
        $que = mysqli_query($con, "INSERT INTO orders VALUES('', '$date', '$cust_id')");
    }

    // Fetching serial from orders table. This also works correct.
    $q = mysqli_query($con, "SELECT serial FROM orders WHERE customerid = '$cust_id'");
    while ($row1 = mysqli_fetch_array($q, MYSQLI_ASSOC)) {
        $serial = $row1['serial'];
        echo $serial ."\n";
    }
    //Problem comes here. Here i am trying to insert values in order_details
    foreach ($_SESSION['cart'] as $id => $value) {
        $subtotal = $value['price'] * $value['quantity'];
        $pid = $value['id'];
        $quantity = $value['quantity'];
        $color = $value['color'];
        $size = $value['size'];
    }
    mysqli_query($con, "INSERT INTO order_detail VALUES ($serial, $pid, $quantity, $subtotal, $color, $size)");
    if (true) {
        echo "success";
    } else {
        echo"not success";
    }
}

你有没试过这个？

if( mysqli_query($con, "INSERT INTO order_detail VALUES ($serial, $pid, $quantity, $subtotal, $color, $size)") ){
   echo "success";
    } else {
        echo"not success";
    }

我认为你最好能以这种方式进行插入：

INSERT INTO order_detail (column1, column2, column3,...)
VALUES (value1, value2, value3,...)

插入查询回显成功但不在mysql数据库表
