PHP购物车 - 添加变量 - 网页学习体会

问题描述：

I am creating a PHP cart for a photography business. This is the 1st Ecommerce site I have attempted (Newbie)

I have managed to add products to the cart (stored in the session) (Products: Print, Keyring, Magnet ect)

However I also need to add the imageID to the session

Here is my code

$product_id = $_GET[id];     //the product id from the URL 
    $imageId = $_GET[imageid];   //the image id from the URL 
    $action     = $_GET[action]; //the action from the URL 

    switch($action) {   //decide what to do 

        case "add":
            $_SESSION['cart'][$product_id]++; //add one to the quantity of the product with id $product_id 
        break;

Which saves the product to the basket

The cart.php url is shown as:

cart.php?imageid=83&id=12&action=add

Could anyone help/advise how I add the Image ID to the product?

Thanks

开关的动作（$ action）{//决定做什么
 
 case“add”：
 $ _SESSION ['cart'] [$ product_id] ++;  //在产品数量上添加一个ID为$ product_id 
 break;

答

This is assuming one image can be used by different products? Otherwise, you should simply be able to deduce which image to use based on the product ID:

case "add":
    $_SESSION['cart'][$product_id]++; //add one to the quantity of the product with id $product_id
    $_SESSION['images'][$product_id] = $imageId; //Will map the image ID to the product being added
break;

Anyway, without seeing your actual markup, adding the image to the basket should be something like:

<basket element>
    <item element>
        <img src="path/to/images/<?=$_SESSION['images'][$product_id]?>.filetype" />
    </item>
</basket>
