Creating a cookie (with expiry date)

**Macca** · 09-13-2010, 03:25 PM

I have had trouble creating a cookie with an expiry date set in the fututre.

Grateful for any help.

Code:

<script language="JavaScript">
<!--
function setcookie(name, value, store) {
if (store >= 1) {
var expire = new Date ();
if (store == 1) {
expire.setTime (expire.getTime() + (365*24*60*60*1000));
}
if (store == 2) {
expire.setTime (expire.getTime() + (1*24*60*60*1000));
}
} else {
var expire = null;
}
document.cookie = name + "=" + escape(value) + "expires=Mon, 14 Sep 2020 18:49:22 GMT";
}
function cookie_icons_offset() {
var now = new Date ();
var browser_time = now.getTime();
setcookie("lastvisit", browser_time, 1);
var server_now = "1284390825";
if (server_now != "") {
var offset = browser_time - (1000*server_now);
setcookie("offset", offset, 1);
}
}
// -->
</script>

Thanks for your help. I have now set the expiry date but I seem to have an issue with the cookie storing username and passwords.

For some strange reason the username and password are expiring on the 6th September. I am using a discussion forum app called discusware 4.0. Not sure were the expiry date is set. What I want to do is update the function initpage to set the expiry date myself. Grateful for any help.

Code:

<script language="javascript">
	<!-- ;
		function initpage () {
		  if (document.userpass) {
		    if (document.userpass.username) {
		      if (document.userpass.username.value == "") {
		        document.userpass.username.value = readcookie("user$COOKIE_ID")
			
		      }
		    }
		    if (document.userpass.passwd) {
		      if (document.userpass.passwd.value == "") {
		        document.userpass.passwd.value = readcookie("rpwd$COOKIE_ID")
			
		      }
		    }
		  }
		<#if $GLOBAL_OPTIONS{cookie_for_new} == 1#>
			  cookieinit();
			}
			<#insert part ($head->{topic_number}) "cookie_icons"#>
			if (document.images) {
				<#foreach $subtopic (@subtopics)#>
					<#if $subtopic->{lastmod} ne ""#>
						if (($subtopic->{lastmod} - server_gmt_offset) > compare_time) {
							document.img$subtopic->{number}.src = img_new.src;
						}
					<#endif#>
				<#endloop#>
			}
		<#endif#>
		}
		<#insert part ($head->{topic_number}) "readcookie"#>
	// end hide -->
	</script>
