login script problem

[illuz1on]

Hey,

 

Getting this error from my login.php, anyone know why it might be happening?

 

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/remember/public_html/admin/login.php:1) in /home/remember/public_html/admin/login.php on line 2

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/remember/public_html/admin/login.php:1) in /home/remember/public_html/admin/login.php on line 2

Welcome to the remember online administration section..Please login...

 

Then displays the fields...

 

Thanks alot,

 

Chris

 

<?php
session_start();

include "db.php";

if ($_GET["op"] == "login")
{
if (!$_POST["username"] || !$_POST["password"])
  {
  die("You need to provide a username and password to access this page. This is a restricted area. Information Logged.");
  }


$q = "SELECT * FROM `remusers` "
  ."WHERE `username`='".$_POST["username"]."' "
  ."AND `password`='".$_POST["password"]."' "
  ."LIMIT 1";

$r = mysql_query($q);

if ( $obj = @mysql_fetch_object($r) )
  {

  $_SESSION["valid_id"] = $obj->id;
  $_SESSION["valid_user"] = $_POST["username"];
  $_SESSION["valid_time"] = time();


  
  $username = $_POST["username"];
  setcookie("admin",1);
  Header("Location: admin.php");
  }
else
  {
  die("Sorry, could not log you in. Wrong login information.");
  }
}
else
{
echo "Welcome to the remember online administration section..";
echo "Please login...";
echo "<form action=\"?op=login\" method=\"POST\">";
echo "Username: <input name=\"username\" size=\"15\"><br />";
echo "Password: <input type=\"password\" name=\"password\" size=\"8\"><br />";
echo "<input type=\"submit\" value=\"Login\">";
echo "</form>";
}
?>

Session auto start is probably on in your php.ini file, it might not be the best but I use:

try
{
	if ( !@ ( session_id() ) )
		throw new Exception ("oh no!");
}
catch (Exception $e)
{
	session_start();
}

If anyone has any other suggestions / improvements here i'd also appreciate!

Do you think you could post the contents of db.php too? The error looks like you might have called session_start in the db.php too which would cause that error.
