postpone the sending of header information

[tolkienarda]

hi all.

i am getting an error:
[PHP]
Warning: session_registe r() [function.sessio n-register]: Cannot send session cookie - headers already sent by (output started at C:\wamp\www\WTA \admin\login.ph p:14) in C:\wamp\www\WTA \admin\login.ph p 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="localhos t"; // Host name.
$db_user="eric" ; // MySQL username.
$db_password="d al4120"; // MySQL password.
$database="wytr kcms"; // Database name.
$cms = mysql_pconnect( $host, $db_user, $db_password) or trigger_error(m ysql_error(),E_ USER_ERROR);
mysql_select_db ($database, $cms);
if(isset($_POST[uname]))
$user=$_POST[uname];
if(isset($_POST[pass]))
$pass=$_POST[pass];
session_start() ;
//session_destroy ();
echo '1';
$result=mysql_q uery("SELECT user, pass FROM users WHERE pass = '$pass' AND user='$user'");
$row=mysql_fetc h_row($result);
echo '2';
if($row[0] == $user && $row[1] == $pass)
{
session_registe r("user");
header("locatio n:index.php");
}
else
{
header("locatio n:login.htm");
}

?>
[/PHP]

me error says the problem is occuring on session_registe r("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?una me=1016&pass=12 3
Note that i used $_GET so do the changes. :)

[PHP]<?
$host="localhos t"; // Host name.
$db_user="root" ; // MySQL username.
$db_password="d ba"; // MySQL password.
$database="test "; // Database name.
$cms = mysql_pconnect( $host, $db_user, $db_password) or trigger_error(m ysql_error(),E_ USER_ERROR);
mysql_select_db ($database, $cms);
if(isset($_GET['uname']))
$user=$_GET['uname'];
if(isset($_GET['pass']))
$pass=$_GET['pass'];
session_start() ;
//session_destroy ();
//echo '1';
$result=mysql_q uery("SELECT p_id, p_name FROM products WHERE p_id = '$user' AND p_name='$pass'" );
$row=mysql_fetc h_row($result);
//echo '2';
if($row[0] == $user && $row[1] == $pass)
{
session_registe r("user");
header("locatio n:index.php");
}
else
{
header("locatio n:login.htm");
}

?> [/PHP]
