Hi All,
I have an input field with type="password".
I am trying to do some error checking to see if the user puts a value in
after they submit the form (i.e not left it blank)
Here is what I have:
on form:
Password: <input id="PASSWORD" name="PASSWORD" type="password"
size="15">
In PHP error checking:
if (empty($_POST[PASSSWORD]))
{ $GERROR="TRUE";}
even though I am putting characters in the field before I submit I am
always
getting TRUE returned.
This same tactic works for other fields I have that I need to make
sure they
put values in, just I have never done this before with a password field.
What am I doing wrong? I just want to make sure they put something
there!

If that's a direct copy/paste from your actual code, there is an extra
S in PASSWORD. Also, you should enclose the array key in quotes:
if (empty($_POST['PASSWORD']))
{ $GERROR='TRUE'; }

try if trim() gives you any different result:
if (empty(trim($_POST['PASSWORD'])))
{ $GERROR='TRUE'; }
definitely gives a different result.
$ php -r '
$r = " "; var_dump(empty(trim($r)));'
PHP Fatal error: Can't use function return value in write context in Command line code on line 2
you can only pass variables to empty() *not* expressions.
:-)
yup... didn't think that way...
though, I was giving an idea
$password = trim($_POST['PASSWORD']);
if (empty($password)
{ $GERROR='TRUE'; }
;-)
