actually so does empty end up testing true on an empty var...

Thus isset() returns true.
Actually, I believe it's not a matter of the input being set, but the fact
that isset() returns true on an empty variable.
It's fairly easy. isset returns true if the VARIABLE itself exists,
like if it's been declared, or set by a form. isset isn't checking the
VALUE of the VARIABLE, just if it exists. In Jason's example below,
isset returns false because the VARIABLE was never declared in some way,
shape or

Thanks for clearing that up.
Hmm, it seems like you still haven't grasped it yet :)
So input of type text does a set, which makes
isset() true,
Correct.
but isset() does not return true if $var is merely empty.

They both work, you're just not using the correct logic or something.
Show your code again... your actual code that isn't working (so you say)
and the form that's being submitted. Also, is register_globals on or
off?
Load this small bit of code as proof that it works:
form method=POST

I am running to this same problem. The isset() function appears to have
problems with the empty text value. The empty() function sees the value
of $_POST['q1'] as expected.
So why is both isset() and empty()
