postpone the sending of header information

[tolkienarda]

hi all.

i am getting an error:
[PHP]
Warning: session_register() [function.session-register]: Cannot send session cookie - headers already sent by (output started at C:\wamp\www\WTA\admin\login.php:14) in C:\wamp\www\WTA\admin\login.php on line 20
[PHP]

and two other similar header errors. so i think i need to somehow stop the sending of headers untill the end of my script if anyone can impart their wisdom on the matter i would be greatful

you always want to set header information at the top of your code

ok

maybe my code isn't formated right. here is the code

[PHP]
<?
$host="localhost"; // Host name.
$db_user="eric"; // MySQL username.
$db_password="dal4120"; // MySQL password.
$database="wytrkcms"; // Database name.
$cms = mysql_pconnect($host, $db_user, $db_password) or trigger_error(mysql_error(),E_USER_ERROR);
mysql_select_db($database, $cms);
if(isset($_POST[uname]))
$user=$_POST[uname];
if(isset($_POST[pass]))
$pass=$_POST[pass];
session_start();
//session_destroy();
echo '1';
$result=mysql_query("SELECT user, pass FROM users WHERE pass = '$pass' AND user='$user'");
$row=mysql_fetch_row($result);
echo '2';
if($row[0] == $user && $row[1] == $pass)
{
session_register("user");
header("location:index.php");
}
else
{
header("location:login.htm");
}

?>
[/PHP]

me error says the problem is occuring on session_register("user"); line and the one below it. or if the password is incoret then on the other redirect tag.
do you know what i am doing wrong

remove those echo '0' and echo '1' lines, i don't know what is reason for those stuffs.since you are using them in this first the page try to print them, then you can't use the session_start().
and wrap the post element with single quotes.

[PHP]if(isset($_GET['uname']))
$user=$_GET['uname'];
if(isset($_GET['pass']))
$pass=$_GET['pass'];[/PHP]

I change your script against to one of my table and it works.and redirected to index.htm with the values like this:
http://localhost/thescripts/621150/session.php?uname=1016&pass=123
Note that i used $_GET so do the changes. :)

[PHP]<?
$host="localhost"; // Host name.
$db_user="root"; // MySQL username.
$db_password="dba"; // MySQL password.
$database="test"; // Database name.
$cms = mysql_pconnect($host, $db_user, $db_password) or trigger_error(mysql_error(),E_USER_ERROR);
mysql_select_db($database, $cms);
if(isset($_GET['uname']))
$user=$_GET['uname'];
if(isset($_GET['pass']))
$pass=$_GET['pass'];
session_start();
//session_destroy();
//echo '1';
$result=mysql_query("SELECT p_id, p_name FROM products WHERE p_id = '$user' AND p_name='$pass'");
$row=mysql_fetch_row($result);
//echo '2';
if($row[0] == $user && $row[1] == $pass)
{
session_register("user");
header("location:index.php");
}
else
{
header("location:login.htm");
}

?> [/PHP]
