Hi, below is the very start of my code for a login screen. I need to use a cookie so i can carry the username of the user through to another welcome page and display their information stored in a database.

<?$username = $_POST['UserName'];
setcookie("user",$username);?>
<?php include("header.inc");?>

These are the errors is get:

Notice: Undefined index: UserName in C:\Program Files\Apache Group\Apache2\htdocs\Login.php on line 1

Warning: Cannot modify header information - headers already sent by (output started at C:\Program Files\Apache Group\Apache2\htdocs\Login.php:1) in C:\Program Files\Apache Group\Apache2\htdocs\Login.php on line 2

Can anyone help me to solve these??

Thanks for any help

You are opening and closing PHP twice in three lines, and using short tags on one of them, first try rewriting the below

<?$username = $_POST['UserName'];
setcookie("user",$username);?>
<?php include("header.inc");?>

To something like this

<?php $username = $_POST['UserName'];
setcookie("user",$username); 
include("header.inc");?>

Read this from the manual

Like other headers, cookies must be sent before any output from your script (this is a protocol restriction). This requires that you place calls to this function prior to any output, including <html> and <head> tags as well as any whitespace. If output exists prior to calling this function, setcookie() will fail and return FALSE.

Function setcookie

Is the code that you are showing the first of the file login.php, where is it getting the $_POST{'UserName'] from? If there is any output even a space before a setcookie then that is what is causing the error if you want you could try turning off warnings by @setcookie().

If you are running on localhost this might be worth your while to read:
