Seems to me that the problem might be in the logic (correct me if I'm wrong
- likely - but...)
In these lines :
foreach ($cart as $id => $qty)
{
if ($$id == "0")
{
unset ($cart[$id]);
.....
[snip]
You unset $cart[$id] if $$id==0. Now, if you are using numeric array
indexes, then for example $id might be '12' (number or string, it don't
matter). So what you're asking of php is to get $$id, that works out as $12
, which I guess is not a variable name.
Not being a variable it will return false (or zero) and so $$id=="0" will
be true, your if statement executes and unsets the value for $cart[$id],
which *is* a valid variable name. Could you replace $$id==0 with
isset($$id) and see if you get the same results?
