Yeah, this is just a leftover from the earlier function. It is only called  
once and that is to test it, I will remove that part later. It will also  
be a comma separated list, too, so it explodes into an array.

I did not know that! Thank you very much! No more  
$array[$arrayKeys[$index]] and array_keys() for me!

I just did that because I thought it might make a difference. Turns out it  
doesn't.
This really seems like a bug to me, because the loop works, the $fields  
value is correct, but it just won't return the type. If I put a $temp var  
in there that gives me the TCA, $temp = $GLOBALS['TCA'], it give me an  
error when I try to open it in the debug view. Even echoing the $type only  
works once, so it can't be my debugger or IDE, either. Very odd.

Thanks for the help, I will make those changes now and see if they make a  
difference.
