setcookie and isset($_COOKIE(name)) seem very finnicky.

Posted on 16th Feb 2014 07:03 pm by admin

I'm currently playing around with a user system with login and registration. I'm trying to use cookies to log the user in but the cookie either doesn't set or it sets after I travel through a few pages. Also, when I use isset($_COOKIE(name)) it sometimes doesn't return that it is set even though it is.

login.php (the username and password request page which I am currently using to display if a cookie is set)
Code: <?php
if (isset($_COOKIE["grocerycookie"]))
{
$username = $_COOKIE["grocerycookie"];
echo "You are logged in, <b>$username</b><br />";
}
else
{
echo "You have not been logged in.";
}
?>


login2.php (sets the cookie)
Code: <?php
mysql_connect("*", "*", "*") or die(mysql_error());
mysql_select_db("*") or die(mysql_error());
$username = strtolower($_POST['username']);
$password = $_POST['password'];
$data = mysql_query("SELECT * FROM * WHERE username='$username'") or die(mysql_error());

while($info = mysql_fetch_array($data))
{
if ($password == $info['password'])
{
setcookie("grocerycookie", $username, time()+3600);
}
}

Am I setting the cookie wrong or checking for it wrong?
