You might also try to process the results from the form first, and then,
if errors are found, display the form again and put the data in there
yourself. No need to send the user back and forth. But you may need to
restructure your code a little. I personally always use this method.
1) Check if form is sent.
1a) True? Check form contents. Put errors in a variable. If there are no
errors, do whatever you need to do.
1b) False? Set all form fields to the default values (probably empty strings).
2) Check if error variable exists.
2a) True? Print error variable on the screen.
3) Print form, and load values in them.
