# 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.

## SignalSlots List¶

File Located in Signal Name Available Parameters Description
NewController.php createAction() createActionBeforePersist $user,$this Use this signal if you want to hook into the process before the new user was persisted
NewController.php confirmCreateRequestAction() confirmCreateRequestActionBeforePersist $user,$hash, $status,$this Use this signal if you want to hook into the confirmation process
NewController.php createAdminConfirmationRequest() createAdminConfirmationRequestAutoConfirm $user,$this Signal if a user was auto-confirmed
NewController.php createAdminConfirmationRequest() createAdminConfirmationRequestManualConfirmation $user,$this Signal if a user was not auto-confirmed and must be confirmed manually
EditController.php updateAction() updateActionBeforePersist $user,$this Use this signal if you want to hook into the process before the user- profile was updated
EditController.php confirmUpdateRequestAction() confirmUpdateRequestActionAfterPersist $user,$hash, $status,$this Use this signal if you want to hook after a profile was accepted or refused
EditController.php deleteAction() deleteAction $user,$this Use this signal if you want to hook into the process before the user- profile will be deleted
InvitationController.php createAction() confirmUpdateRequestActionBeforePersist $user,$hash, $status,$this Use this signal if you want to hook into the process before a new user was persisted
InvitationController.php createAllConfirmed() createAllConfirmedAfterPersist $user,$this Use this signal if you want to hook into the process after a new user was persisted
InvitationController.php editAction() editActionAfterPersist $user,$hash, $this Use this signal if you want to hook into the process before a user adds a new password (step 1) InvitationController.php updateAction() updateActionAfterPersist$user, $this Use this signal if you want to hook into the process after a user adds a new password (step 2) UserController.php loginAsAction() loginAsAction$user, $this Use this signal if you want to hook into the process after you simulate a frontend user login UserBackendController.php confirmUserAction() confirmUserAction$user, $this Signal if a user profile was confirmed in backend module UserBackendController.php refuseUserAction() refuseUserAction$user, $this Signal if a user profile was refused in backend module AbstractController.php finalCreate() finalCreateAfterPersist$user, $action,$this Use this signal if you want to hook into the process after the new user was persisted
AbstractController.php updateAllConfirmed() updateAllConfirmedAfterPersist $user,$this Use this signal if you want to hook into the process after the new user was persisted

## 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

$signalSlotDispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\SignalSlot\\Dispatcher');$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);
}
}
