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.

use SilverStripe\Forms\ReadonlyField;
use SilverStripe\Security\Security;
use SilverStripe\ORM\DB;
use SilverStripe\ORM\DataExtension;

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

    public function afterMemberLoggedIn() 

    public function memberAutoLoggedIn() 

    public function updateCMSFields(FieldList $fields) 
        $fields->addFieldsToTab('Root.Main', [
            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',

Now you just need to apply this extension through your config:
