PHP Cookie is not working,,,,

Now i am currently coding a PHP site and i am implementing the login page for my site, but the remember me feature in my script is not working,,,

here is the code which i placed in header.php after the body tag,,,

<?php
   if(isset($_COOKIE['username']) && isset($_COOKIE['userid']))
   {
      $_SESSION['USERNAME'] = $_COOKIE['username'];
      $_SESSION['USERID'] = $_COOKIE['userid'];
   }
?>

PHP:

this is the code which i placed in login.php

 if(isset($_POST['remember']))
            {
                setcookie("username", $_SESSION['USERNAME'], time()+60*60*24*100, "/");
                setcookie("userid", $_SESSION['USERID'], time()+60*60*24*100, "/");
            }

PHP:

i selected remember me option while loging in and i logged in,,, after that i closed the browser without loging out,,,,, when i open the page again it is not auto loging,,, please help me with this,,,

 

are you getting the cookie data ?

Please try printing out the cookie data

print_r($_COOKIE)

and see its there. I think you might be needing to set the cookie path also if your $_COOKIE is not having those keys.

 

You can't put it after the body tag. You have to check for the cookies before headers are sent.
Use headers_sent function to check.

 

What are you tring to do it's very dangerous.
Your way if i know the username and the userid i can login in the user account.

 

i tried this, but nothing is printed

i placed the script about doctype, but still no result

i know, i am first checking the cookie function without database,,,

 

thank you very much, it works great,,,

 

we will just pretend you didn't say this
