Hmm. I see what you are getting after, but in some cases wouldn't
this be a bad thing for me? Case in point, When this particular page
loads it always grabs my $_POST values and places them into the form.
If its your first time there, the form is empty because the values
are empty (which is what I want).
If I do the above, my form fields will all have "false" in them, or I
have to put some logic before the field to say 'if its false, its
blank'. (the page posts to itself)
Also, if I want to check if my var has a value, can't I just do the
if(isset($var)) if/when I need to check for its value?
I'm no php guru, so just asking :)
