cookie

[knuff]

My poll wont work, Im lost. It dosent write cookies anymore. Wzup?

Problem: Write cookie, if(empty($vote)) dosent work... The $vote is set by a hidden input when you press submit. If I disable the if(empty($vote)) the vote will be counted but no cookie will be written. Need help thanks.

<?php
if($radiopoll==1)
{
echo 'radiopoll 1';
if(empty($vote))
	{
	mysql_query("UPDATE polli SET ja=ja+1");
	$vote=1;
	setcookie("pollcookie", $vote, time()+3600*1000, "http://localhost/mysqltestar/");
	}

 }

if($radiopoll==2)
{
echo 'radiopoll 2';
if(empty($vote))
{
	mysql_query("UPDATE polli SET nej=nej+1");
	$vote=1;
	setcookie("pollcookie", $vote, time()+3600*1000, "http://localhost/mysqltestar/");

}
 }
?>

Hi there,
I think your problem is that you are writing some output before you're setting the cookie. Cookies have to be set before any other header, read the manual page for setcookie()
http://www.php.net/manual/en/function.setcookie.php
, then you'll probably understand better what I mean.

drtebi may be right, as you do need to send a cookie before any output, however, you said wont send cookies ANYMORE. I'm assuming that it used to? If it did, check your host and see what Register_Globals is set to in the php.ini. You can use a <?php phpinfo(); ?> script to see this. If it's turned on, you shouldn't have a problem, but if it's turned off, you'll need to refer to your $vote variable, as $_POST['vote']. This is for security reasons.

See more on the PHP website, just search around for register globals, there's heaps of reference material on there.

and still dosent stop me from vote as much as I want to. But the cookie will be written. What I want to do is.
1. If no cookie, make one with no vote
2. If cookie with no vote, allow vote
3. If cookie with vote, dont allow vote

this is my script, you can reda the $rostat as "$i_have_voted" for yourself to get a clear picture.

if(empty($rostat))
{
	$rostat=nej;
	setcookie("pollcookie", $rostat, time()+3600*1000, "http://localhost/mysqltestar/");
}
if($radiopoll==1)
		{
		if($rostat=="nej")
			{
				mysql_query("UPDATE polli SET ja=ja+1");
				$rostat="ja";
				setcookie("pollcookie", $rostat, time()+3600*1000, "http://localhost/mysqltestar/");
			}
		}
if($radiopoll==2)
		{
		if($rostat=="nej")
			{
			mysql_query("UPDATE polli SET nej=nej+1");
			$rostat="ja";
			setcookie("pollcookie", $rostat, time()+3600*1000, "http://localhost/mysqltestar/");
			}
		}

The problem is that after the first vote $rostat will be changed to "ja" but the if($rostat=="nej") dosent work at all and ist just a simple if... i dont get it.

did you read matt's post?

if register globals were off, $rostat would always be empty, so the cookie would be set at first.

but $rostat would never be "nej", so the rest would never be executed.

could you please look it up in your php.ini or via phpinfo() to clarify if this is the problem or if it's something else?

[knuff]

and Register Globals ar turned on. On Local Value & Master Value. Thanks for all the tips. But it still dosent work, for all of you who thinks that the problems is that the cookie must be first. Pls give me a hint!

one more idea, not sure if it helps but give it a try:

the 4th argument to setcookie is supposed to be the path, not the domain, that might be messing things up. inserting "/" there should make it available to the entire domain.

setcookie("pollcookie", $rostat, time()+3600*1000, "/", "http://localhost/mysqltestar/");

[knuff]

it didnt help... 🙁

Have you tried viewing the contents of $rostat to make sure that it actually has what you expect in there?

[knuff]

Im tought of that to and this is how it works. When I have voted the $rostat will be set to "ja" even in the cookie so when i try to vote one more time it just ignores the $rostat I even tried with

if (!isset($HTTP_COOKIE_VARS['pollcookie']))

insted of

if($rostat=="nej")
