[PHP] Form Variables

[NeoDreamer]

Psuedo code:


$user = $_POST['user'];
$password = $_POST['password'];

if((!$user) or (!$password))
{
// form code
// action = self
}
else
{
// check database for match
// reload page if no match
}

When this page first loads, it will only run the "if" code. On the first try, a user fills out both fields so the page reloads and then runs the "else" code. He fails to provide a valid username and password, so the page reloads a second time. On this second reload, will $user and $password be null?

I'm having the problem that on the second reload, those variables appear to not be null, so NO code is run at all!

$user = $_POST['user'];
$password = $_POST['password'];

if((!$user) or (!$password))
{
// form code
// action = self
}
else
{
// check database for match
// reload page if no match
}


Should work.

Looks like someone missed a simple ! sign...

I'm not asking if it works or not. I'm asking whether the post variable retains it's original value after many reloads of the page.

It's reloading via hitting the post button. The form action=self.

If the form is being resubmit, it'll have the same post headers defined (those in the form).

If not, it'll not retain the post headers.
