ronverdonk Posted August 30, 2006 Share Posted August 30, 2006 You cannot have a header sent after you have outputted anything to the screen, not even a blank!So you usually put the header() call before all the html stuff.Ronald 8) Link to comment https://forums.phpfreaks.com/topic/19125-cant-deal-with-that-header/#findComment-82710 Share on other sites More sharing options...

ronverdonk Posted August 30, 2006 Share Posted August 30, 2006 Here it is: header before any HTML or other output:[code]<?php include "connect.php";if (logIn($_POST['username'], $_POST['password']) ) header("Location: adminarea.html");else die; function logIn($uid, $pwd) { // connect to the mysql server $link = mysql_connect($server, $db_user, $db_pass) or die ("Could not connect to mysql because ".mysql_error()); // select the database mysql_select_db($database) or die ("Could not select database because ".mysql_error());$match = "select id from $table1 where username = '$uid' AND password = '$pwd'"; $qry = mysql_query($match) or die ("Could not match data because ". mysql_error()); $num_rows = mysql_num_rows($qry); if ($num_rows <= 0) { ?><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><title>Untitled Document</title><meta http-equiv="Content-Type" content="text/html; charset=windows-1251"></head><body bgcolor="#000000" text="#FF0000" link="#FFFF00" vlink="#FFFF00" alink="#FFFF00"><div align="center"> <?php echo "<p>wrong username or password !</p>"; echo "<a href=adminlogin.html>Go Back</a>"; return false; } else return true;}?>[/code]Ronald 8) Link to comment https://forums.phpfreaks.com/topic/19125-cant-deal-with-that-header/#findComment-82730 Share on other sites More sharing options...
AndyB Posted August 30, 2006 Share Posted August 30, 2006 Dammit - why is this problem posted twice. PLEASE do NOT post the same thing in different forums - it confuses and wastes people's time.
