Hi I have been doing a tutorial online for an Image Gallery and the first part of it is a simple Login to the Admin section for the gallery. For some reason when I run the script out of Dreamweaver ( i have local server all set up with Apache and MySQL), the login page appears and when i click on submit nothing happens. the login page just reappears. I can see that a session file is created in 'c:/phptmp' with the details isLogin|b:1;. It has to be something simple related to the Header command or sessions. When I change header to redirect to a simple normal page as a test, it works. is this piece of code correct? header('Location: index.php?page=list-album'); i can attach the code if needs be.
The header statement looks fine to me. Just make sure your index.php script handles the page variable correctly. Post the code here so we can take a look.
here is the three relevant scripts,,,, login.php <?php session_start(); require_once('Connections/conn_fanad.php'); require_once ('Connections/functions.php'); $errMsg = ''; if (isset($_POST['txtUserid'])) { // Check the user login. For now we only check it // against a hardcoded value if ($_POST['txtUserid'] == 'bigbadwolf' && $_POST['txtUserpw'] == 'huffnpuff') { $_SESSION['isLogin'] = true; //header('location: index.html'); //Redirects it header('Location: index.php?page=list-album'); exit; } else { $errMsg = "Wrong Id/Password"; } } ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Login</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <p> </p> <?php if ($errMsg != '') { echo '<p align="center"><font color="#990000">' . $errMsg .
