[SOLVED] Naming cookies with variables

[Nexus Zero]

My aim with this code is to prevent multiple votes on a single comment. I'm attempting to do this by adding an arrayed cookie that has a unique entry added each time a user votes. However, when I echo the following code

 

<?php 

$judgement = $_GET['j'];
$commentid = $_GET['cid'];

setcookie("cookie[$commentid]", $commentid);

?>

 

I get this error message: Notice: Undefined index: cookie[$commentid] in /home/fhlinux166/t/trivipedia.org/user/htdocs/judge.php on line 46

 

$commentid is a number, such as 1, 18 etc.

 

Does php have rules against this or am I doing it wrong?

 

Thanks.

Is line46 this line?

setcookie("cookie[$commentid]", $commentid);

 

That should be fine

 

To fetch the cookie you'd use this variable:

$_COOKIE['cookie'][$commentid];

 

Not like this:

$_COOKIE['cookie[$commentid]'];

Mate that's fantastic. I've since applied that syntax to an isset and the code works perfectly.

 

Many, many thanks!
