No cookie value on other pages

Question

The page im posting to has the following code, and echo's the cookie correctly:

/* verify.php */

if ($age >= "21"  && $location == "USA" && $cookie == "Y") {

    $value = "1";
    setcookie("age_verified", $value, time()+60*60*24*30);
    header("Location: ../portal.php?cookieset");
}
elseif ($age >= "21" && $location == "USA") {

    session_start();
    $_SESSION['age_verified'] = "1";
    header("Location: ../portal.php?sessionset");   
}

On portal.php i am not able to echo the cookie, but the session shows up fine if that option is chosen.

/* portal.php */

session_start();
echo $_SESSION["age_verified"];

Result is "1"

/* portal.php */

echo $_COOKIE["age_verified"];

No Result

I'm trying to achieve something like the code block below, but it's not working properly since cookie doesn't echo a result /* portal.php */ session_start();

if($_SESSION['age_verified']!="1"){
    header("Location: index.php?no_session");
}
elseif ($_COOKIE['age_verified']!="1"){
    header("Location: index.php?no_cookie");
}
else{
    echo "";    
}

What am i missing?

Answer 1

It would seem to me that $_SESSION['age_verified']!="1"||$_COOKIE['age_verified']!="1" is checking against EITHER session or cookie values. Cookie values are more persistent as they are stored on the user's machine, and session values only persist to a browsing session. They may not both be set.

In fact, looking at your logic on verify.php you are performing one action OR the other, not both. Hope this helps.
