Hey guys,
I need some quick help with an error I am getting in my login page. I am taking a php course for work and stuck on this error. The exact error is:
Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /home/scott321/public_html/dl.php:1) in /home/scott321/public_html/login.php on line 12
Warning: Cannot modify header information – headers already sent by (output started at /home/scott321/public_html/dl.php:1) in /home/scott321/public_html/login.php on line 14
I did some research on this and supposidely it is because of blank spaces after my php closing statement. However I checked this everywhere and do not see any issues.. my db is set up with the table correctly. Below is a copy of the 3 php files I am using (dl.php, login.php, checklogin.php)
dl.php:
[CODE]<?php
$username=”scott321_user”;
$password=”********”;
$database=”scott321_contacts”;
$con = mysql_connect(localhost,$username,$password);
if (!$con)
{
die(‘Could not connect: ‘ . mysql_error());
}
mysql_select_db($database, $con) or die(“Couldn’t open $database: “.mysql_error());;
?>
login.php:
[CODE]<?php
if($_POST[‘Submit’]){
include(“dl.php”);
$userid = $_POST[‘userid’];
$password = $_POST[‘password’];
$query = “select * from users where userid=’$userid’ and password=’$password'”;
$result = mysql_query($query,$con) or die(‘Error: ‘ . mysql_error());
$num = mysql_num_rows($result);
mysql_close();
if ($num > 0 ){
session_cache_limiter(‘public’);
session_start();
$_SESSION[‘views’] = 1;
header (“Location: show_contacts.php”);
exit();
}
else {
echo “invalid userid or password try again”;
}
}?>

checklogin.php:

Any help is appreciated greatly!
