Which means it's not getting an array. So look and see what it IS
getting. What is the value of $data at that point? (Use echo(),
print_r(), something like that to output the value.)
I can see the error right away, looking back over the code. It's a
fairly stupid error on my part introduced while refactoring the
working code into an example you could pick apart and learn from.
I want you to find it, because otherwise you will never stand on your
own here.
