What is in the $data array? [FormAPI]

Example code $data[0]:

PHP:

switch($data[0]){//buttons
  case 0:
  case 1:
}

​

 

case 0: The First button
case 1: The Second button
case 2: The the third button
Etc....

 

What if its a custom form? Would each element still be in order.. Would a Label also add to the index.

 

If it's an CustomFrom if I remember fine $data != 0 but if you need an exempt I here

 

Absolutely agree

 

At least it can be used with master pmmp
