How would I log a successful login

Question

How would I log a successful login within the zfc-user module for the purpose of showing the user the last time he/she was successfully authorized?

I'm thinking a listener as zfcuser uses events, but are unable to figure it out

Answer 1

There's an authenticate event created in the module, which you can hook into (check example inside AdapterChainServiceFactory)

$chain = new AdapterChain;
$adapter = $serviceLocator->get('ZfcUser\Authentication\Adapter\Db');
$chain->getEventManager()->attach('authenticate', array($adapter, 'authenticate'));

You can hook onto the event, and then do some logging if the authenticate was a success, something like this:

// Attach onto the event somewhere...
$chain->getEventManager()->attach('authenticate', array($myObject, 'logAuthenticate'));

// MyObject
public function logAuthenticate(AuthEvent $e)
{
    // logging magic here..
}
