Question

我需要协助尝试从我正在循环的订单中获取信息。我需要能够将用户信息上方的订单信息输入到用户信息表中，这样我就可以将项目和用户信息提交到数据库中。但看起来我需要提交附加订购用户的多个项目。

这是部分代码

if(isset($_POST["get_cart_product"]) || isset($_POST["cart_checkout"])){
            $uid = $_SESSION["uid"];
            $sql = "SELECT * FROM cart WHERE user_id = `$uid` ";
            $run_query = mysqli_query($con,$sql);
            $count = mysqli_num_rows($run_query);
            if($count > 0){
                $no = 1;
                $total_amt = 0;
                while($row=mysqli_fetch_array($run_query)){
                    $id = $row["id"];
                    $pro_id = $row["p_id"];
                    $pro_name = $row["product_title"];
                    $pro_image = $row["product_image"];
                    $qty = $row["qty"];
                    $pro_price = $row["price"];
                    $total = $row["total_amt"];
                    $price_array = array($total);
                    $total_sum = array_sum($price_array);
                    $total_amt = $total_amt + $total_sum;
                    setcookie("ta",$total_amt,strtotime("+1 day"),"/","","",TRUE);
                    if(isset($_POST["get_cart_product"])){
                        echo "

您不能将单引号＆＃39; 用于整数变量。详细了解此When to use single quotes, double quotes, and backticks in MySQL

使用此查询

 $sql = "SELECT * FROM cart WHERE user_id = `$uid` ";

而不是这个

$sql = "SELECT * FROM cart WHERE user_id = '$uid'";
