如何將相同的商品添加到購物車頁面，但商品尺寸不同？

Question

我想在購物車頁面添加不同類型的產品？如何將相同的產品添加到購物車頁面，但產品尺寸不同？

我要像這個購物車

1）產品1950年的小 2）產品1950年的大 3）產品1950 XL

* 的JavaScript *

<script language="javascript"> 
function addtocart(id){ 
document.form1.id.value=id; 
document.form1.command.value='add'; 
document.form1.submit(); 
} 
</script> 

Php代碼

$sizes=$_POST['size']; 
include("cart/functions.php"); 
if($_REQUEST['command']=='add' && $_REQUEST['id']>0){ 
$id=$_REQUEST['id']; 
addtocart($id,1); 
header('location:shoppingcart.php?size='.$sizes.'');  
exit(); 
} 

表1放入購物車

<form name="form1" method="post"> 
<input type="hidden" name="id" /> 
<input type="hidden" name="command" /> 
</form> 

大小形態

<form action="" id="size1" name="size1" method="post"> 
<div class="details clearfix"> 
<p class="item"> 
<label style="font-family:Arial,Helvetica,sans-serif; font-size:12px; font-weight:bold; ">Choose your size:</label> 
<select style="background-color:#CCC" name="size" id="size" > 
<option>Select</option> 
<option value="Small">Small</option> 
<option value="Medium">Medium</option> 
<option value="Large">Large</option> 
<option value="XL">XL</option> 
</select> 
</div> 

放入購物車按鈕

<div class="buy"> 
<?php 
$query3=mysql_query("select * from products WHERE id='$id' "); 
$row3=mysql_fetch_array($query3); 
?> 
<input type="button" class="button1" value="Add To Cart" > 
</div> 
</form> 

購物車頁面

    ?> 

Answer 1

相反，你可以使用會話做到這一點，購買成功後，將其添加在數據庫中。

例

if(isset($_SESSION['items'][$_GET['item_id']])) { 
    $_SESSION['items'][$_GET['item_id']]++; 
    //multiply price code 
} else { 
    $_SESSION['items'][$_GET['item_id']] = 1; //If added for the first time 
    //set session for price 
}
