i am in the middle of making an online community setup... i recently started taking on the forum part of it...

now, my question is... how would one go about making those "folder" icons highlight when there are new posts there?

if you need to take a look, here is the site...

i want to make all those green icons dark green when there are posts in there the user has read, and the color they are now when there are new posts... any idea?

Well, here at the Asylum, westore the last visit time, as well as the time we last saw you.
Then we color anything newer than last visit time, updating the last visit time
if it's smaller than last seen time -15 minutes or some such.

I can get you the code, but not right now...

ok, here you go:

This is being done on every request to the Asylum

code:
// set cookies for the highlighting of unread forums & threads
$iMinimumTimeBetweenVisits = 900;
if (g_retrieveUserSetting('lastVisit') !== NULL && (time() - $iMinimumTimeBetweenVisits > g_retrieveUserSetting('lastVisit')))
{
	g_storeUserSetting('lastVisit',g_retrieveUserSetting('thisVisit'));
}
elseif  (g_retrieveUserSetting('lastVisit') === NULL)
{
	g_storeUserSetting('lastVisit',time());
}
g_storeUserSetting('thisVisit',time());




g_***UserSettings are basically wrappers around a cookie

code:
function g_storeUserSetting($strKey,$value)
{
	$arrData = false;
	if (isset($_COOKIE[$GLOBALS['g_str']['%%cookiename']. 'settings']))
	{
		$arrData = @unserialize(urldecode($_COOKIE[$GLOBALS['g_str']['%%cookiename']. 'settings']));
	}
	if (!is_array($arrData))
		$arrData = array();
	$arrData[$strKey] = $value;
	$strData = urlencode(serialize($arrData));
	setcookie($GLOBALS['g_str']['%%cookiename']. 'settings',$strData,time() + 3600 * 24 * 30,'/',CONFIG_DOMAIN,0);
	$_COOKIE[$GLOBALS['g_str']['%%cookiename']. 'settings'] = $strData;
}

function g_retrieveUserSetting($strKey)
{	
	if (isset($_COOKIE[$GLOBALS['g_str']['%%cookiename']. 'settings']))
	{				
		$arrData = @unserialize(urldecode($_COOKIE[$GLOBALS['g_str']['%%cookiename']. 'settings']));
		if (isset($arrData[$strKey]))
			return $arrData[$strKey];
		else
			return NULL;
	}
	return NULL;	
}



and of course, the actual function to check if something is newer...

code:
function g_isNewSinceLastVisit($pageDate)
{
	$strFormat = "Y-m-d H:i:s";
	if (is_numeric($pageDate))
		$pageDate = date($strFormat,$pageDate);
	return ((g_retrieveUserSetting('lastVisit') != '') && $pageDate > date($strFormat, g_retrieveUserSetting('lastVisit')));
}



Hope this helps you,
so long,
