我想在购物车页面中添加不同类型的产品？如何将相同的产品添加到购物车页面但产品尺寸不同？

我想要这个购物车

1) 产品 A 1950 小 2) 产品 A 1950 大 3) 产品 A 1950 XL

* javascript *

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

php代码

$sizes=$_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();
}

加入购物车的表格 1

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

尺寸表

<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>

添加到购物车按钮

<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>

购物车页面

相反，您可以使用会话来执行此操作，并在成功购买后将其添加到数据库中。

例子

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
}

参考。
