Personally, I could see two solutions.
1. p1.php would post to itself. Do data validation. After data validation
upon error, include p1.php again with included error messages
upon success, redirect to p3.php with congrats.
2. p1.php would post to p2. perform data validation.
upon error, save data into session variable, redirect back to p1.php,
display error messages inline
upon success, redirect to p3.php, display congrats
I personally like the second option. It is cleaner. Each page/script has a
single purpose in life.
It just makes better sense to my small little mind.
