Namtip Posted September 20, 2010 Share Posted September 20, 2010 Problem: The page does not redirect the end user to main.php. Notice: Use of undefined constant name_id - assumed 'name_id' in C:\x\xampp\htdocs\pages\form_process.php on line 48 Warning: Cannot modify header information - headers already sent by (output started at C:\x\xampp\htdocs\pages\form_process.php:48) in C:\x\xampp\htdocs\pages\form_process.php on line 87 The error messages displayed above make it seem like they are connected to the problem, but I don't understand why 'name_id' is undefined as its auto increments in mysql. I also think my .htaccess might be preventing me from redirecting, is that possible? " header('Refresh: 5; URL=http://localhost/pages/main.php'); " Goal: redirect user to main.php without error messages being displayed. form_process.php <?php //let's start our session, so we have access to stored datasession_start();if (isset($_POST['terms_and_conditions']) == 0) { // the code was incorrect // handle the error accordingly with your other error checking // or you can do something really basic like this die('You must agree to the terms and conditions to create a profile.

KevinM1 Posted September 20, 2010 Share Posted September 20, 2010 We have a stickied topic describing 'headers already sent' errors: http://www.phpfreaks.com/forums/index.php/topic,37442.0.html Also name_id is not the same as $name_id.

Namtip Posted September 21, 2010 Author Share Posted September 21, 2010 I changed this code to remove the "Notice: Use of undefined constant name_id - assumed 'name_id' in C:\x\xampp\htdocs\pages\form_process.php on line 48" error. This in turn solved the knock on error. I also later looked for any whitespaces as recommended in the other linked post $query = sprintf("INSERT INTO user ( name, password) VALUES ('%s','%s')", mysql_real_escape_string($_SESSION['values']['name']), mysql_real_escape_string(md5(SALTY . $_SESSION['values']['password']))); //let's run the query $result = mysql_query($query, $db) or die(mysql_error($db)); Thanks guys.
