neex1233 Posted December 19, 2010 Share Posted December 19, 2010 This has been driving me crazy for hours! I am trying to set a cookie: setcookie("username", $_POST['user']); And for a while it wasn't working, then it started randomly working. Now, when I try to use if(isset($_COOKIE['username'])) PHP is saying the cookie does not exist. PLEASE help! Thanks.

quelle Posted December 19, 2010 Share Posted December 19, 2010 use the setcookie function before any <html> tags cuz cookies have to be sent before any header information otherwise wont work. If the problem still is there try adding these 2 line before the function ob_start(); ob_clean(); Link to comment https://forums.phpfreaks.com/topic/222106-cookies/#findComment-1149119 Share on other sites More sharing options...
neex1233 Posted December 19, 2010 Author Share Posted December 19, 2010 It's not before any tags, and those tags aren't helping. I tried putting var_dump($_COOKIE); on the page I'm having the problem, and it doesn't do anything. However, if I do it on a different page, it works.

Pikachu2000 Posted December 19, 2010 Share Posted December 19, 2010 You have an echo immediately before you attempt to set the cookie. That won't work that way, there can be no output to the browser prior to setting the cookie.

neex1233 Posted December 19, 2010 Author Share Posted December 19, 2010 It's not the actual making of the cookie that's the problem, it's the detection of the cookie. The cookie is made fine, I've checked in Add 'n Edit Cookies, but this code: <?php ob_start(); ob_clean(); $user = $_COOKIE['username']; if(isset($user)) { } else { header("location: /users/login.php"); } ?> isn't working. The code works on other pages, though. Link to comment https://forums.phpfreaks.com/topic/222106-cookies/#findComment-1149130 Share on other sites More sharing options...
PFMaBiSmAd Posted December 19, 2010 Share Posted December 19, 2010 You are not using the 4th parameter in the setcookie(), so the cookie is only available at the same path where it was set.
