Need help with Cookies

Anon

Hi,
I'm having a hard time with the following.

I have a PHP page with a form containing a check box. I need to set a cookie with the value of the checkbox ie either enabled or disabled such that when the page is regenerated based on the check field criteria the checkbox is enabled if it were before or else if a person had enabled the feature the last time the page was visited the checkbox is enabled.

I've modified a snippet of code that I found online to set the value of the checkbox but it doesn't seem to work.Could someone see what is wrong.

Thanks

<?php
SetCookie("optioncookie",$optionenabled);

if(isset($optioncookie))
{
echo "Cookie just set.<BR>";
}
else
{
echo "Cookie was not set.<BR>";
}
?>

function getCookie(name) { // use: getCookie("name");
	var bikky = document.cookie;
	var index = bikky.indexOf(name + "=");
	if (index == -1)
	{
	     //if cookie not set
                           document.form.optionenabled.value =$optionenabled;
		return null;
	}
	index = bikky.indexOf("=", index) + 1; // first character
	var endstr = bikky.indexOf(";", index);
	if (endstr == -1) endstr = bikky.length; // last character
	document.form.optionenabled.value = unescape(bikky.substring(index, endstr));

}
</script>

<BODY onload="getCookie('optioncookie')">

im not sure if this is going to make a difference or not but try adding a third param to your setcookie function so it reads.

SetCookie("optioncookie",$optionenabled,3600);

that will set the cookie so that it expires after 3600 seconds, or an hour
