This is what most probably is causing the problem. I am using the RewriteEngine and the URLs are similar to this forum, where it's "example.com/ab/cd". Seems to be working better when use the domain. This is what my setcookie function looks like now: $domain = ($_SERVER['HOST_NAME'] == "localhost" ? "localhost" : "." . DOMAIN); setcookie("rm_session", $username . "-" . $randomString, strtotime('+1 month'), "/", $domain); Also my domain creates two PHPSESSID cookies when I go to my website with www. and without. How can I fix this?

Have you modified anything in your .htaccess file? Could it be that your PHP script takes too long to run?

Ok, the query gets executed, but the cookies don't update. I don't see why it works for a couple of times and then it doesn't.

As far as I can see, there are no values which are outputted before the cookies are set. I do have E_ALL and display_errors set to ON. 1 second, I'll try to do the logging of timestamps. I do have a timestamp in my remember_auths table, so I'll just make one for the cookies.

<?php var_dump($row_rsOsprey); echo $row_rsOsprey['tour_header_08']; ?> Try this ^ instead.

Hello, my login system sometimes doesn't log me in. I have been trying to solve this for a past couple of days, and I can't figure out whats wrong as sometimes it works and sometimes it doesn't. For my website, I use an MVC, and in my Model superclass I initiate the user class. The User class logs the user in using a constructor: function __construct() { //print_r($_SESSION); if (!isset($_SESSION['user_data']) || $_SESSION['user_data']['loggedIn'] === false) { if (isset($_COOKIE['rm_session'])) { $cookieInfo = explode("-", $_COOKIE['rm_session']); if ($this->checkCookie($cookieInfo[0], $cookieInfo[1])) { $this->updateCookie($cookieInfo[0]); $this->loginId($this->getId($cookieInfo[0])); return; } } $this->loginGuest(); } } This checks if the session is set, if not it will check the cookie. Here is my check cookie function: public function checkCookie($username, $token) { $sql = "SELECT token, time FROM remember_auths WHERE username = :username ORDER BY time DESC"; $sth = Model::$db->preparedQuery($sql, array( ":username" => $username, )); $data = $sth->fetch(PDO::FETCH_ASSOC); if (!empty($data)) { if ($this->validateString($token, $data['token'])) { $time = time() - strtotime($data['time']); if ($time < 2592000) { return true; //all good! } else { echo "times are wrong!"; return false; //cookie auth too old | can be checked in query? } } else { echo "invalid tokens"; return false; //invalid token } } else { echo "cookie not found"; return false; //no cookie found } } When the website logs the user in, it updates the cookie. Here is the function for that: public function updateCookie($username) { $randomString = $this->generateString(); setcookie("rm_session", $username . "-" . $randomString, strtotime('+1 month'), "/"); Model::$db->preparedQuery("INSERT INTO remember_auths (username, token) VALUES(:username, :token)", array( ":username" => $username, ":token" => $this->cryptString($randomString) )); } For some reason, this login system doesn't log the user in sometimes when the user revisits. For debugging, I have echo'ed out where the login system fails, and it seems that the tokens do not match. I can't figure out what is causing this as I am saving the cookie and the token into the database in the same function. It seems as if half of the function gets called, and the other doesn't. How can I fix this? Thank you in advance. Also sorry if my code is horrible.

Are pages.BGimageID and bgimages.BGimageID in your $row2 array? If not then you might not be joining the tables correctly.

Do print_r($row2) to check what you are receiving from the query. I don't think you need the 'pages.' and 'bgimages.' here: if($row2['pages.BGimageID'] == $row2['bgimages.BGimageID']){

There are no pages.BGimageID and bgimages.BGimageID keys in your $row2 array. You need to use mysql_fetch_assoc, instead of mysql_fetch_array.

You cannot use the 'if' keyword in the middle of functions or variable assignments. Take a look at this http://www.php.net/manual/en/language.expressions.php Sorry for horrible wording.

Hello, I am working on a login system for my website, more specifically the remember me feature. I have made it so my PHP script saves an authentication token as a cookie, and then encrypts the token and then saves the encrypted token into a database when the user logs in. If the cookie is already set and there is no session, the application will validate the cookie and then generate a new token and then log the user in. I have tested the remember me feature by removing the PHPSESSID, to check whether or not the remember me feature will use the cookie correctly to log me back it. However, I have noticed that sometimes the cookie would not update, thus causing me to stay logged out and preventing me from logging in again. Is there a way to fix this? If you are wondering, here is my code that updates the token: public function updateCookie($username) { $randomString = $this->generateString(); setcookie("rm_session", $username . "-" . $randomString, strtotime('+1 month'), "/"); Model::$db->preparedQuery("INSERT INTO remember_auths (username, token) VALUES(:username, :token)", array( ":username" => $username, ":token" => $this->cryptString($randomString) )); } I am also trying to make the cookie HTTP only; however, for some reason it is not letting me to set a domain, every time that I set a domain, the cookie doesn't show up. It's most probably because I am using the RewriteEngine. Is there a way to fix this aswell? I have tried using the domain as localhost, null, false and 127.0.0.1, but it didn't work.

You can also use Ajax to send values to a PHP page which can insert those values into a database. You can also use jQuery which will be simpler solution. Have a look at this: http://api.jquery.com/jQuery.post/

It is impossible to pass a JavaScript variable to PHP. JavaScript is executed on the client side (on your browser), and PHP is executed on the server side.

Hi, I am using PBKDF2 to crypt my passwords, but I am not sure whether or not I am using it correctly. I create a random 32 character string and use it as salt, and use it to crypt the password, then I store both the encrypted password and the salt into the database. Is this the correct way to use the PBKDF2 crypting? Also, for my remember me feature I store the encrypted password and the user ID into a cookie which is used to log the user in. This method doesn't look very secure to me for some reason. Is there a better way to implement the remember me feature?

Oh wait. Will the ip2long6 work for IPv4? I'm so confused right now. I'm going to sleep, I need to rebuild my blown up brain. Hopefully we will get it working tomorrow.

Well, I have just made a test page to test the functions from the php.net site. Here is the code: <?php $ipv6 = "2001:4860:a005::68"; function ip2long6($ipv6) { $ip_n = inet_pton($ipv6); $bits = 15; // 16 x 8 bit = 128bit while ($bits >= 0) { $bin = sprintf("%08b",(ord($ip_n[$bits]))); $ipv6long = $bin.$ipv6long; $bits--; } return gmp_strval(gmp_init($ipv6long,2),10); } function long2ip6($ipv6long) { $bin = gmp_strval(gmp_init($ipv6long,10),2); if (strlen($bin) < 128) { $pad = 128 - strlen($bin); for ($i = 1; $i <= $pad; $i++) { $bin = "0".$bin; } } $bits = 0; while ($bits <= 7) { $bin_part = substr($bin,($bits*16),16); $ipv6 .= dechex(bindec($bin_part)).":"; $bits++; } // compress return inet_ntop(inet_pton(substr($ipv6,0,-1))); } print $ipv6long = ip2long6($ipv6)."\n"; print $ipv6 = long2ip6($ipv6long)."\n"; ?> I got it from here: http://www.php.net/m...2long.php#94477 . (I have enabled gmp-lib.) I'm guessing that I should find a different function.

When I test http://www.php.net/m...2long.php#94477 I get some errors: ( ! ) Notice: Undefined variable: ipv6long in test.php on line 10 and ( ! ) Notice: Undefined variable: ipv6 in :\wamp\www\NewRetrite\test.php on line 28 I am not sure how to fix them. Can anyone help me out?

I have also used this: http://www.php.net/manual/en/function.ip2long.php#109298 . Will it still work with IPv6 ?

If you are the only one who is going to use it then no. But you should still learn how to prevent SQL Injections and stuff.

Hi, I have been coding my site on Windows 7 and I have decided to check out Windows 8. And I'm guessing that windows 8 use IPv6 And when I test my website some of the features do not work correctly due to IPv6. It is because I use ip2long functions to check stuff and ip2long doesn't work for IPv6 IPs. Is it possible to convert IPv6 to IPv4 (i doubt it)? If not, then is there an alternative I method that I can use to convert IPs to longs?

Every file is a binary file as they are made out of 1s and 0s. I don't think it is possible to restore it as it is filled with 0s and there is no way to tell what has been there.
