Sessions not working,

[Anon]

I cannot get my session information to store, I know I am doing something wrong but I cannot seem to get the UNAME and PASS variables to store?

index.php
<?
session_start();
session_register("module");
session_register("UNAME");
session_register("PASS");
global $module, $UNAME, $PASS;

$module="login.php";

include "$module";
?>

login.php
<?php

function showlogin($username="", $password="") {

?>
<FORM ACTION="<?=$PHP_SELF?>" METHOD="Post">
Username:<INPUT TYPE=text NAME=username VALUE="<?echo $username?>">
<BR>
Password:<INPUT TYPE=text NAME=password VALUE="<?echo $password?>">
<BR>
<INPUT TYPE="submit" VALUE="login">
</FORM>
<?
$UNAME=$username;
$PASS=$password;
}

if(!isset($UNAME)) {
showlogin();
}
else
{
$passwd="test";
if ($PASS==$passwd)
{
echo("logged in ");
}
else
{
echo("There was problem with your username or password<BR>");
showlogin($UNAME,$PASS);

}
}
?>

Hello Doug,
it is simple, because you have the form, which includes two input fields username and password, when the login button is pressed then this two variables (username and password ) are sent to the script (not this two named UNAME and PASS ).

I think, that it can work when the button is pressed one time and after that when it appears, when you press next time the login button.

I think that you can take the two lines from function showlogin with:

$UNAME=$username;
$PASS=$password;

and you have to put them just before the line with:
if(!isset($UNAME)) {

This has variables assigned to $PASS and $UNAME, they will not change, its as if once they are set, they cannot be changed??
