I've noticed an annoying bug in the current site I'm building, if spaces are entered into a form field (and nothing else) then technically the field isn't empty and so it manages to get past the error checking.

I could use str_replace(" ", "", $thefield) in an if statement to check if it is only spaces, but that seems a bit of an overkill - is there a regex i can do to check if a string contains something other than just spaces

so " " would return false (i.e, only spaces)
and "fd ad sf" would return true (i.e it's not empty)

cheers

can't you just use the php function trim() before you validate?
