Login script problem

[nicolette]

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');

//host name
$host = "localhost";
//mysql login info
$username = "root";
$password = "";
//DB info
$db_name = "syllabus";
//DB table info
$tbl_name = "syll";

//Connecting to server and selecting the DB
mysql_connect("$host", "$username","$password") or die ("cannot connect to the database");
mysql_select_db("$db_name") or die ("cannot select the database");

//send username and password from form
$user = $_POST['user'];
$pass = $_POST['pass'];

//protection for mysql
$user = stripslashes($user);
$pass = stripslashes($pass);
$user = mysql_real_escape_string($user);
$pass = mysql_real_escape_string($pass);

$sql = "SELECT * FROM $tbl_name WHERE user='$user' and pass='$pass'";
$result = mysql_query($sql);

//Count rows
$count = mysql_num_rows($result);

// if there is a match there must be only one row
if ($count == 1)
{
	//register the session and redirect to next page
	session_register("user");
	session_register("pass");
	header("location:FinalPart5Form2.php");
}
else
{		
	echo "Invalid username $user or password $pass";
}
?>

 

I receive these errors:

Deprecated: Function session_register() is deprecated in C:\xampp\htdocs\FinalPart5ProcessForm1.php  on line 39

Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively in Unknown on line 0

 

I have checked for whitespace and there is none but the first time i attempted to log in i spelled it wrong and got the echo statement "invalid blah blah..." does that cause this header problem?

 

I know that the session_register is depreciated and is now $_SESSION() i just haven't quite figured out how to use it.

 

Does anyone see the problem or is the session_register depreciation causing the header problems?

 

thanks

You're getting the header problems because of the warning messages being sent to the screen.

 

To use the SESSION variables, you need to put

<?php
session_start()
?>

at the beginning of your code and then instead of

<?php
	session_register("user");
	session_register("pass");
?>

use

<?php
$_SESSION['user'] = $user;
$_SESSION['pass'] = $pass;
?>

 

To check whether they are set, use

<?php
if (isset($_SESSION['user']))
?>

//register the session and redirect to next page
	session_start();
	$_SESSION['user'] = $user;
	$_SESSION['pass'] = $pass;
	header("location:FinalPart5Form2.php");

 

ok so while I was waiting I played with the code and changed the session stuff it removed all the errors I was getting in the previous post but now i'm getting told that the redirect location  was not found on this server which i find interesting because i was just playing with that file

 

**ken you posted as I was typing this you said to do everything that i did so it is nice to know I was on the right track However I didn't know about the:

if (isset($_SESSION['user']))

would I do another one for the password?

 

anyway i'm off to play some more just thought I would post this for anyone else who was having the same problems.
