QUOTE(elevenmil @ Apr 5 2005, 03:44 PM) Although I'm doing some tweaking, I have finally got just about everything down in developing a login feature to my website, but just one problem. The session terminates too quickly. For instance, someone will be instructed to login, and after browsing a couple pages, it'll come up again that the user is not logged in. In addtion, this occurs frequently but not all the time. What can I do that will eliminate this inconvience to my viewers?  Hmmm... use setcookie don't use session id's or go to http://www.google.com/search?q=sessions+site:php.net login.php CODE <? /** * Checks whether or not the given username is in the * database, if so it checks if the given password is * the same password in the database for that user. * If the user doesn't exist or if the passwords don't * match up, it returns an error code (1 or 2). * On success it returns 0. */ function confirmUser($username, $password){ global $conn; /* Add slashes if necessary (for query) */ if(!get_magic_quotes_gpc()) { $username = addslashes($username); } /* Verify that user is in database */ $q = "select password from users where username = '$username'"; $result = mysql_query($q,$conn); if(!$result || (mysql_numrows($result) < 1)){ return 1; //Indicates username failure } /* Retrieve password from result, strip slashes */ $dbarray = mysql_fetch_array($result); $dbarray['password'] = stripslashes($dbarray['password']); $password = stripslashes($password); /* Validate that password is correct */ if($password == $dbarray['password']){ return 0; //Success! Username and password confirmed } else{ return 2; //Indicates password failure } } /** * checkLogin - Checks if the user has already previously * logged in, and a session with the user has already been * established. Also checks to see if user has been remembered. * If so, the database is queried to make sure of the user's * authenticity.
