Using SignalSlots (Hook pendant) to extend femanager

Introduction

SignalSlots (former Hooks) are the possibility for other developer to extend the runtime of a femanager process with their own code.

As an example let’s build an extension which sends username and email address of a new registered user to a defined email address.

Note: this is a little bit useless because there is already a setting in flexform to inform administrators and there is a setting in TypoScript to POST values to a third-party-software, but let’s use this case for an example.

Use a SignalSlot

Introduction

As described before, we want to send an email to a defined address every time when a new user is registered.

Creating an extension

femanagersignalslot/ext_emconf.php:

This file is important to install your new extension – write something like:

<?php

$EM_CONF[$_EXTKEY] = array(
                'title' => 'femanagersignalslot',
                'description' => 'signalslotexample for femanager',
                'state' => 'alpha',
                'version' => '0.0.1',
                'constraints' => array(
                                'depends' => array(
                                                'extbase' => '6.0.0-6.1.99',
                                                'fluid' => '6.0.0-6.1.99',
                                                'typo3' => '6.0.0-6.1.99',
                                                'femanager' => '1.0.0-1.0.99',
                                ),
                                'conflicts' => array(
                                ),
                                'suggests' => array(
                                ),
                ),
);

femanagersignalslot/ext_localconf.php:

This is an example how to use a signal from femanager – in this case we decided to use the signal “createActionBeforePersist” in class “In2codeFemanagerControllerNewController” and want to call a slot in class “In2codeFemanagersignalslotDomainServiceSendMailService” with methodname “send()”

<?php

$signalSlotDispatcher = t3lib_div::makeInstance('TYPO3\\CMS\\Extbase\\SignalSlot\\Dispatcher');
$signalSlotDispatcher->connect(
        'In2code\Femanager\Controller\NewController',
        'createActionBeforePersist',
        'In2code\Femanagersignalslot\Domain\Service\SendMailService',
        'send',
        FALSE
);

femanagersignalslot/Classes/Domain/Service/SendMailService.php:

This is our main class which is called every time a new registration process was initiated.

<?php
namespace In2code\Femanagersignalslot\Domain\Service;

class SendMailService
{

        /**
         * Send mail about user information
         *
         * @param \In2code\Femanager\Domain\Model\User $user
         * @param \In2code\Femanager\Controller\NewController $pObj
         * @return void
         */
        public function send($user, $pObj)
        {
                $message = '
                        New user registered
                        Username: ' . $user->getUsername() . '
                        Email: ' . $user->getEmail() . '
                ';
                mail('your@email.com', 'SignalSlot Test', $message);
        }
}
