Question

我的代码工作正常，我可以添加或删除产品，但是我想为产品添加选项（大小，颜色）。

如果产品选项不同，我该如何将它们添加为新产品

ajax请求；

/* Action on form submit */
$(".item_form").submit(function(e){
    var form_data = $(this).serialize();
    /* AJAX request */
    $.ajax({
        url: "cart.php",
        type: "POST",
        dataType:"json",
        data: form_data
    }).done(function(data){ //if AJAX request if succesfull .....
        var totalItemInCart = $("#items_in_shopping_cart, #items_in_shopping_cart_mobile").html(data.items_in_cart); // get Json data
        var new_item_qty = $("#items_in_shopping_cart, #items_in_shopping_cart_mobile").html(data.all_items); // get Json data
        /* Empty the update info bar before calling it. Otherwise appended content will duplicate. */
        $('#cart_update_info').empty();
        /* append data/info to cart_update_info bar */
          swal({
                title: "Artikel wurde dem Warenkorb hinzugefügt",
                timer: 1000,
                showConfirmButton: false
              });

        /* If shopping cart is still open, items will appear on it at the same time of adding them */
        if($(".shopping_cart_holder").css("display") == "block"){ // Check if shopping cart is open
            $(".shopping_cart_info").trigger( "click" );  // update cart on event
        }
    })
    e.preventDefault();
});

cart.php;

if(session_status()==PHP_SESSION_NONE){session_start();}

if（isset（$ _ POST [“ item_id”]）&& isset（$ _ POST ['item_qty']））{

$added_item["item_id"]=$_POST['item_id'];
$added_item["item_qty"]=$_POST['item_qty'];


/* Fetch all items from database that matches $_POST['item_id']
    Limit 1 at the end so only one item is fetched. */

$items = $database->find_by_query("SELECT * FROM shopping_items WHERE item_id='{$added_item["item_id"]}' LIMIT 1");


/* Foreach item -> Remaining data about items fetched from database */
        foreach($items as $item){

            $added_item["item_name"] = $item['item_name'];
            $added_item["item_price"] = $item['item_price'];

            /* Update item session array with newly added items - items that already exist in the basket will be overwritten */
            $_SESSION["items"][$added_item['item_id']] = $added_item;
        }

/* Calculate number of items in cart and output it in json format */
exit(json_encode(array('items_in_cart'=>count($_SESSION['items']))));

}

/ *添加项目数量-每个项目最多允许添加10个项目* /

if(isset($_GET["add_itm_qty"]) && isset($_SESSION["items"])){

if(isset($_SESSION['items'][$_GET["add_itm_qty"]])){
    if($_SESSION['items'][$_GET["add_itm_qty"]]["item_qty"] <= 9){
        $_SESSION['items'][$_GET["add_itm_qty"]]["item_qty"]+=1;
    }else{
        $_SESSION['items'][$_GET["add_itm_qty"]]["item_qty"]=10;
    }
}

unset($_GET["add_itm_qty"]);
exit(json_encode(array('items_in_cart'=>count($_SESSION['items']),(array('all_items'=>$_SESSION["items"])))));}

/ *减去项目数量-仅在item_qty不小于0时减去数量* /

if(isset($_GET["subtruct_itm_qty"]) && isset($_SESSION["items"])){

if(isset($_SESSION['items'][$_GET["subtruct_itm_qty"]])){
    if($_SESSION['items'][$_GET["subtruct_itm_qty"]]["item_qty"] >= 2){
        $_SESSION['items'][$_GET["subtruct_itm_qty"]]["item_qty"]-=1;
    }else{
        $_SESSION['items'][$_GET["subtruct_itm_qty"]]["item_qty"]=1;
    }
}
unset($_GET["subtruct_itm_qty"]);
/* Get item quantity and output it in json format */
exit(json_encode((array('item_qty'=>$_SESSION["items"]))));}

/ *从购物车中删除商品* /

if(isset($_GET["remove_item_from_cart"]) && isset($_SESSION["items"])){

$item_id = $_GET["remove_item_from_cart"];

 /* Check if item is ina item session array */
if(isset($_SESSION["items"][$item_id])){
    unset($_SESSION["items"][$item_id]);  // Remove/unset item
}


/* Calculate total number of items in cart and output it in json format */
exit(json_encode(array('items_in_cart'=>count($_SESSION['items']))));}

使用AJAX向购物车添加变化
