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.

namespace App\Extension;

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

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()) {

            'UPDATE "Member" SET "LastVisited" = %s, "NumVisit" = "NumVisit" + 1 WHERE "ID" = %d',

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

    - App\Extension\MyMemberExtension
