如何将记录的每一行插入数据库的表“ receipt”中？

每行购买记录作为图片。

这是我最近实现的代码

if (isset($_POST["add"])){
    if(!isset($_SESSION["cart"][$_GET["id"]]['item_quantity'])){
        $_SESSION["cart"][$_GET["id"]]['item_quantity'] = 0;
    }
    $_SESSION["cart"][$_GET["id"]]['item_name'] = $_POST["hidden_name"];
    $_SESSION["cart"][$_GET["id"]]['product_price'] = $_POST["hidden_price"];
    $_SESSION["cart"][$_GET["id"]]['item_quantity'] = $_SESSION["cart"][$_GET["id"]]['item_quantity'] + $_POST["quantity"];

    header('Location: counter.php');
}

if (isset($_GET["action"])){
    if ($_GET["action"] == "delete"){
        foreach ($_SESSION["cart"] as $keys => $value){
            if ($value["id"] == $_GET["id"]){
                unset($_SESSION["cart"][$keys]);
                echo '<script>alert("Product has been Removed")</script>';
                echo '<script>window.location="counter.php"</script>';
            }
        }
    }
}

if (isset($_POST["minus"])){
    if(!isset($_SESSION["cart"][$_GET["id"]]['item_quantity'])){
        $_SESSION["cart"][$_GET["id"]]['item_quantity'] = 0;
    }
    $_SESSION["cart"][$_GET["id"]]['item_name'] = $_POST["hidden_name"];
    $_SESSION["cart"][$_GET["id"]]['product_price'] = $_POST["hidden_price"];
    $_SESSION["cart"][$_GET["id"]]['item_quantity'] = ( ( ( $_SESSION["cart"][$_GET["id"]]['item_quantity'] - $_POST["quantity"] ) > 1 ) ? 
    $_SESSION["cart"][$_GET["id"]]['item_quantity'] - $_POST["quantity"] : 1 );

    header('Location: counter.php');
}
<?php 
    $total_price = 0;
    $change = 0;
    $selectOption = 0; 
    if(!empty($_SESSION["cart"])){
    foreach ($_SESSION["cart"] as $key => $value) {
?>

            </tr>

receipt_id

购买名称

product_quantity

价格

价格

总计

日期
