IE not accepting my cookies

alex_bg

Hello all,
I run php poll, that has IP blocking and cookies as means of protection from cheaters. But Internet explorer does not accept my cookies... do you know if there's something I can do about it?

If you have cookies enabled in your IE setting, then please post the code you use to set your cookie and the code you use to read the cookie value.

I am not sure if I am posting the right data, but here is an excert of 1) functions.inc.php and 2) poll.php:

1)
// cookie check
if (isset($tapps_cookie) && $tapps_cookie==TRUE)
{
if (in_array($poll_id, $already_voted))
{
die("You have already voted.<br>\n");
}
}

1)
// cookie
if (isset($tapps_cookie) && $tapps_cookie==TRUE)
{
array_push($already_voted, $poll_id);
$cookie_value = serialize($already_voted);
setcookie("$tapps_cookie_name","$cookie_value",time()+31536000);
// if we force the user to accpet the cookie then create a pending vote
// and redirect to that url
if (isset($tapps_cookie_force) && $tapps_cookie_force==TRUE)
{
$db_value = serialize($options);
$id = md5(uniqid(rand()));
db_query("INSERT INTO tapps_pending (id,poll_id,options) VALUES('$id',$poll_id,'$db_value')");
$url = "http://".$HTTP_SERVER_VARS['HTTP_HOST'].$HTTP_SERVER_VARS['PHP_SELF']."?mode=activate&pending_id=$id";

		// don't redirect now if we have email confirmation enabled (handled later)
		if (isset($tapps_email_confirmation)==FALSE || $tapps_email_confirmation!=TRUE ||
		    isset($voter_email)==FALSE || $voter_email == "")
		{
			header("Location: $url");
			echo "<html><body></body></html>";
			exit;
		}
	}

2)
// verify cookie data
if (isset($tapps_cookie) && $tapps_cookie==TRUE)
{
$already_voted = array();
if (isset($HTTP_COOKIE_VARS["$tapps_cookie_name"]))
{
$already_voted = unserialize(stripslashes($HTTP_COOKIE_VARS["$tapps_cookie_name"]));

	if (is_array($already_voted) == FALSE)
	{
		die("Invalid cookie data.<br>(Don't mess with the input. I don't trust you!)<br>\n");
	}
	foreach ($already_voted as $option_id)
	{
		if (is_numeric($option_id) == FALSE)
		{
			die("Invalid cookie data.<br>(Don't mess with the input. I don't trust you!)<br>\n");
		}
		$option_id = (int)$option_id;
	}

}

}

Thank you for trying to help me.

Just a quick review on your code, you should refer to your cookie by the name $tapps_cookie_name and not $tapps_cookie

setcookie("$tapps_cookie_name","$cookie_value",time()+31536000);

Is that your issue?

alex_bg

Excuse me, but I didn't understand you:
the line you posted is just the same as the one in my poll? Is that what has to be edited? What did you advise me? I am really sorry, but I am into misunderstanding 😕 😕
You mean that I should change all the $tapps_cookie with $tapps_cookie_name ?
Sorry again for not catching you.

Umm... what is exactly that $tapps_cookie? Are you referring to the cookie that you set using this line of code:

setcookie("tapps_cookie_name","$cookie_value",time()+31536000);

If yes, then you are refering to the wrong variable. Coz the cookie should be accessed either by $_COOKIE['tapps_cookie_name']; or $HTTP_COOKIE_VARS['tapps_cookie_name'] or $tapps_cookie_name ONLY.

Note: notice that there should not be any $ sign in front of the name of the cookie inside the setcookie function.

Thank you scoppc! In fact, the removal of the $ sign solved the problem!
Thank you very very much again!!
