As soon as you've fixed that, this would work, but it is not
recommendable. Having a clear view of what your user actually submitted,
and how you've handled/altered the data after that will save you lots of
debugging time.
And just on a side note: shouldn't it be "/^[\d]{5}$/" ? The regex now
will consider '12345and then some arbitrary text or characters' valid...
Yes, of course it should. I got sloppy because the input form is maximum
size 5.

Here is is. You have whitespace between '?>' and '" />', which will
probably translate itself to a space in the field in HTML context.
Use:' } ?>" />'

That's so dumb I can't even get embarrassed. Even worse, I've fixed the
exact problem before, LOL. Thanks for pointing it out.
I think I need a nap.
