Howto: Track Member Logins

Sometimes its good to know how active your users are, and when they last visited the site (and logged on). A simple LastVisited property on the Member record with some hooks into the login process can achieve this. In addition, a NumVisit property will tell us how often the member has visited. Or more specifically, how often he has started a browser session, either through explicitly logging in or by invoking the "remember me" functionality.

	class MyMemberExtension extends DataExtension {
		private static $db = array(
			'LastVisited' => 'Datetime',
			'NumVisit' => 'Int',

		public function memberLoggedIn() {

		public function memberAutoLoggedIn() {

		public function updateCMSFields(FieldList $fields) {
			$fields->addFieldsToTab('Root.Main', array(
				ReadonlyField::create('LastVisited', 'Last visited'),
				ReadonlyField::create('NumVisit', 'Number of visits')

		protected function logVisit() {
			if(!Security::database_is_ready()) return;
				'UPDATE "Member" SET "LastVisited" = %s, "NumVisit" = "NumVisit" + 1 WHERE "ID" = %d',
