creativkook Posted March 5, 2006 Share Posted March 5, 2006 I have a script for a log in that works on another database and site, but doesn't seem to agree with the one I'm trying to get it set up on. Can anyone tell me what can be causing this problem and what I need to do to fix it? Here's the code:<?php$username = $_POST['username'];$password = $_POST['password'];if(isset($_POST['login'])){ require("dbheader.php"); $person = mysql_query("SELECT * FROM cafeusers WHERE username = $username AND password = MD5('$password')"); if(mysql_num_rows($person) > 0) { session_start(); $_SESSION['userid'] = $person['userid']; header("location: home.php"); } else { $error = true; }}?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><link href="style2.css" rel="stylesheet" type="text/css" /> <title>Login Page</title></head><body><div class="login"><?phpif($error == true){ echo("<p>Username or password invalid.</p>");}?><form method="post" action="<?=$_SERVER['PHP_SELF'];?>"><p>Username: <input type="text" name="username" value="<?=$_POST['username'];?>" /></p><p>Password: <input type="password" name="password" /></p><p><input type="submit" name="login" value="Login" /></p></form></div></body></html> Link to comment https://forums.phpfreaks.com/topic/4122-help-with-sessions-and-logins/ Share on other sites More sharing options...

This way, if the failure is due to the query, you'll get an error that may hint towards a solution.Posting the current output may help us determine what's wrong as well since we can't see your database...
