kumarrana Posted July 7, 2008 Share Posted July 7, 2008 I am well aware of the error I have been getting but I just can't fix it. Error is Warning: Cannot modify header information - headers already sent by (output started at ..................index.php:18) in ........................login.php on line 28.Can anybody find bugs on it here is the login.php file included on index.php page <?php require_once('mysql_login.php'); session_start(); $errorMessage = ''; if(isset($_POST['txtUserId']) && isset($_POST['txtPassword'])) { // check if the username and password combination is correct $userpass = md5($_POST['txtPassword']); $username = $_POST['txtUserId']; $result = mysql_query("SELECT * FROM user WHERE password='$userpass' AND username='$username'") or die("Couldn't query the user-database."); $row_user = mysql_fetch_array($result); $num = mysql_result($result, 0); if(!$num) { $errorMessage = 'Sorry, wrong username / password'; } else { $_SESSION['autheticate'] = true; $_SESSION['identification'] = $row_user['identification']; $_SESSION['admin'] = $row_user['admin']; // after login we move to the main page header('Location: ../index.php'); exit; } } ?> and my index page look like this <?php session_start(); if(isset($_SESSION['autheticate'])) { $identification = $_SESSION['identification']; $admin = $_SESSION['admin']; } ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>Title</title> <link rel="stylesheet" href="includes/style.css" type="text/css" /></head> <body> <?php include("header.htm"); echo "<div class = \" verticalmenu \" >"; if(!isset($_SESSION['autheticate'])) { include("includes/login.php"); //echo "<a href = includes/logout.php> Logout </a>"; } else { include("includes/logout.php"); } echo "</div>"; ?> </body> </html> Can anybody tell me what am I doing wrong?

kumarrana Posted July 9, 2008 Author Share Posted July 9, 2008 Even knowing that, I could not avoid the header problem. Instead I used echo "<meta http-equiv = \"refresh\" content = \"1; URL=test.php\">"; Can that be alternative solution? In past I had problem setting session once page is refreshed which I could not debug. I have login.php page included on index.php page. login.php will only appear if session is not set. My login.php page resides in <div></div>. Please somebody help me to get out this pain. btw I tried flush() Link to comment https://forums.phpfreaks.com/topic/113655-error-after-header/#findComment-585137 Share on other sites More sharing options...
trq Posted July 9, 2008 Share Posted July 9, 2008 Its simply a matter of organising your code in such a way that nothing is sent to the browser prior to calling header().
