Hi there,

I'm having an issue with my code and I cannot for the life of me figure out what I'm doing wrong.


The best way is probably to just show you and provide a list, so here is a link to the test site:
http://uberdelic.com/abtest/index.php

And here's your list:

• When I add an item to the cart everything works fine apart from the item number is 0
• If i add another item, the new items number is also 0, next is 1, 2, 3 and so on.
• Now if i try and empty the cart, it does nothing....but click twice and the cart empties?

And I'll paste my cart.php code below. Thankyou to anyone who
actually looks through this, cos it's a mess and as it's not an easy
one, or at least I haven't found it to be.... encouraging huh?

It looks very over complicated to me

 

I would suggest just storing a product ID and qty in session

 

So on each $_POST submission you would do this

 

 

if($_POST['item_id']){
session_start()
$itm_id = $_POST['item_id'];
$qty = $_POST['qty'];
$_SESSION['cart']['items'][$itm_id]+=$qty;
}
 

 

Then use MYSQL to query the DB against the ID's in the cart to show the Items.

 

Drop me a PM if your struggling
