It's basically saying that you are outputing stuff to the browser before you are setting the cookies which is a no go. All header requests (header() & setcookie()) must be run before any text is outputted.
Thus, the most common error is that after or before your php tags <? ?> is empty space, which to PHP is considered outputted text and you wont be able to set any headers. Other than that you might be setting cookies after you have echo'd templates or some such. - James -------------------------- W: www.londontown.com @: [EMAIL PROTECTED] -------------------------- -----Original Message----- From: Anton Heryanto [mailto:[EMAIL PROTECTED]] Sent: 30 May 2002 11:44 To: [EMAIL PROTECTED] Subject: [PHP] user auth.. with mysql and cookies.. help sorry, bother all of you with my same question i was learn to make user auth with mysql and using cookies, i have trouble with this error message; Warning: Cannot add header information - headers already sent by (output started at ../functions.inc:54) in ../functions.inc on line 49 Warning: Cannot add header information - headers already sent by (output started at ../functions.inc:54) in ../functions.inc on line 50 Warning: Cannot add header information - headers already sent by (output started at ../functions.inc:54) in ../functions.inc on line 51 Warning: Cannot add header information - headers already sent by (output started at ../functions.inc:54) in ../login.php on line 12 in this case i use 4 file .. 1)index.html -- sending data (methode post to login.php); 2)login.php 3)function.inc -- all the function i use 4)common.inc -- global variable; 2...login.php................. <?php require 'functions.inc'; deleteCookies(); if (authenticateUser($form_username, $form_password)) { setcookie("cookie_passwd", $form_password); setcookie("cookie_user", $form_username); header("Location:http://$http_host/$docroot/report.php";); exit(); } else{ header("Location:http://$http_host/$docroot/error1.htm";); exit(); } 3.function.inc <? require 'common.inc'; function DisplayErrMsg($message) { printf ("<blockquote><blockquote><blockquote><h3><fontcolor=\"#cc0000\"> %s</font></h3></blockquote></blockquote></blockqoute>\n",$message); } function authenticateUser($user, $password) { global $host, $httphost, $user_db, $password_db, $db, $docroot; if (!
