Hello Everyone,
Thanks for taking your time to look at my post. I am having a problem with my PHP file which is giving me the following error whenever a header("Location: ") is used and the set_cookie function: Warning: Cannot modify header information and it always says the output was started on the first line, i'm really stuck becuase there is no whitespace either.
Error (happens on different lines depending where the header is set):
Warning: Cannot modify header information - headers already sent by (output started at /home/judgeyk1/public_html/judgeysoft.me/frankie/register.php:1) in /home/judgeyk1/public_html/judgeysoft.me/frankie/register.php on line 21
Here is my full file:
<?php
$user = $_COOKIE['userloggedin'];
$error = $_GET['error'];
$login = $_POST['login'];
if(isset($login)) {
$username = strip_tags($_POST['username']);
$password = strip_tags($_POST['password']);
if($username == "" and $password == "") {
header("Location: ?error=both");
}elseif($username == "") {
header("Location: ?error=username");
}elseif($password == "") {
header("Location: ?error=password");
}else{
include("includes/database.php");
$select = mysql_query("SELECT * FROM users WHERE username = '$username' AND password = '$password'");
$check = mysql_num_rows($select);
if($check == "0") {
header("Location: ?error=incorrect");
}else{
$fetch = mysql_fetch_array($select);
$username_new = $fetch['username'];
setcookie("userloggedin", $username_new);
header("Location: account.php");
exit;
}
}
}
if($user != "") {
header("Location: account.php");
exit;
}
$title = "Login";
require("templates/header.php");
?>
