I assume the redisplaying & highlighting errors is not the problem?

In rederecting POST data is indeed lost.
There are several solution:
1. Use the same file for processing the data. (if it's a light application
it's the easiest one).
2. Use a temporary table in which you store the valid post data, preferably
with some auto_incremented key, which you can use as a GET variable on the
redirect (major security leak: other visitors can see what the rest is
doing).
3. Use sessions, and store the valid posted data into the $_SESSION, use
those values in the processing on the other page.
