Pain Posted February 7, 2012 Share Posted February 7, 2012 Hello. I am coding a remember me feature. Everything is working, except i am being logged in using cookies even when i want to use a session. To login using a cookie i must select the checkbox, for sessions i must leave it blank. Here is my code, if someone could spot a mistake i would be really grateful. Login page <?php ob_start(); // starting session... session_start(); // requiring connection... require("functions.php"); // assigning variables... $username = mysql_real_escape_string($_POST['username']); $password = mysql_real_escape_string($_POST['password']); $submit = mysql_real_escape_string($_POST['submit']); $rememberme = $_POST['rememberme']; // querying database... $query = mysql_query("SELECT * FROM users WHERE username = '$username'"); $numrows = mysql_num_rows($query); if ($numrows != 0) { while ($row = mysql_fetch_assoc($query)) { $db_username = $row['username']; $db_password = $row['password']; } } // verifying login details... if ($submit) { if (!empty($username) && !empty($password)) { if ($username == $db_username && $password == $db_password) { if ($rememberme = "on") { setcookie("username", $username, time() + 7200); header('Location: tablets.php'); } else { $_SESSION['username'] = $db_username; $url = $_SESSION['origin'] ? $_SESSION['origin'] : "main.php"; unset($_SESSION['origin']); header('Location: ' . $url); exit; } } else { echo "Incorrect login details"; } } else { echo "You must type in username and password"; } } ob_end_flush(); ?> Login form <?php session_start(); require("connect.php"); if (isset($_SESSION['username']) || isset($_COOKIE['username'])) { header('Location: main.php'); } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Login</title> <link rel="stylesheet" type="text/css" href="form.css" /> </head> <body> <form method="post" action="login.php"> <div class="box"> <h1>Login</h1> <label> <span>Username</span> <input type="text" class="input_text" name="username" id="name" /> </label> <label> <span>Password</span> <input type="password" class="input_text" name="password" id="password" /> </label> <input type="checkbox" name="rememberme" /> <label> <input type="submit" class="button" value="Login" name="submit" /> </label> </div> </form> </body> </html> Quote Link to comment https://forums.phpfreaks.com/topic/256634-unable-to-login-using-sessions/ Share on other sites More sharing options...
spiderwell Posted February 7, 2012 Share Posted February 7, 2012 if ($rememberme = "on") spot anything missing in this?? Quote Link to comment https://forums.phpfreaks.com/topic/256634-unable-to-login-using-sessions/#findComment-1315621 Share on other sites More sharing options...
Pain Posted February 8, 2012 Author Share Posted February 8, 2012 Yes i have just discovered myself that it is something wrong with the checkbox. So how to make something happen when the box is checked? EDIT: !empty worked just fine:) Quote Link to comment https://forums.phpfreaks.com/topic/256634-unable-to-login-using-sessions/#findComment-1315623 Share on other sites More sharing options...
Psycho Posted February 8, 2012 Share Posted February 8, 2012 I think you missed the point. You were using $rememberme = "on" with one equal sign, which is an assignment operator - instead of two equal signs which is the comparison operator. Besides the usual way to identify if a checkbox was checked is simply isset(). In many cases (such as this one) the value of the checkbox really is not important.
