$_SESSION['userpass'] = $_POST['pass'];
$_SESSION['authuser'] = 0;
if (($_SESSION['username'] == 'Joe') and ($_SESSION['userpass'] == '12345'))

When I try login user name: Joe and password: 12345. I will get error. Notice: Undefined index: pass in C:\xampp\htdocs\book\book\movie1.php on line 4 My PHP version is 5.4.7.
moviesite.php
<?php
session_start();
if ($_SESSION['authuser'] != 1)
{echo "you don't enter here.";
exit();
}
?>
<html>
<head >
<title > My Movie Site - <?php echo $_GET['favmovie']; ?> </title>
</head >
<?php
echo "welcome our website, " ;
echo $_SESSION['username'];
echo "."."<br>";
echo "my favorite film is ";
echo $_GET['favmovie'];
echo "<br>";
$movierate= 5;
echo "my point is"." ".$movierate;
?>
</html>
Solution
Change,
<input type="password" name "pass"/></p>
to
<input type="password" name="pass"/></p>
Because of the invalid HTML Markup (missing =), PHP won't see the input "pass". So it won't appear in the $_POST array, so it's giving you an undefined index error because you're trying to reference something that doesn't exist.
