monkeymax Posted April 4, 2006 Share Posted April 4, 2006 I've got a header page (header.php) that I'd like to include with every page. The header.php looks like this:[code]<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://ww.w3.org/1999/xhtml"><head><title>Monkeymax</title><link rel="stylesheet" type="text/css" href="../styles/main.css" /><link rel="stylesheet" type="text/css" href="../styles/sIFR-screen.css" /></head><body><div id="layout"> <div id="header"> <img src="../images/logo.gif" width="140" height="50" alt="Logo" class="logo" /> </div> <div id="container">[/code]I also have a login validation script that I run after the header has been included. This script checks to see if the user is logged in, and if they are not redirects them to the index page. If I don't include my header, it works fine, but if I do I get:[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]Warning: Cannot modify header information - headers already sent by (output started at C:\Apache2\htdocs\monkeymax\web\includes\header.php:8) in [b]C:\Apache2\htdocs\monkeymax\web\includes\secure.inc.php on line 9[/b][/quote]I've become aware that this error is generally caused by whitespace before or after <?php and ?>. How can I include my header without getting this error? Any help would be appreciated.

khendar Posted April 4, 2006 Share Posted April 4, 2006 Run the login validation script before you include the header. Link to comment https://forums.phpfreaks.com/topic/6536-headers-already-sent-dilemma/#findComment-23723 Share on other sites More sharing options...
