Signal/Slots

Existing signals

The following signals exist:

\FGTCLB\T3oodle\Controller\PollController

• list
• show
• vote
• deleteOwnVote
• resetVotes
• showFinish
• finish
• new
• createBefore
• createAfter
• publish
• edit
• updateBefore
• updateAfter
• delete
• finishSuggestionMode
• newSuggestion
• createSuggestionBefore
• createSuggestionAfter
• editSuggestion
• updateSuggestionBefore
• updateSuggestionAfter
• deleteSuggestion

\FGTCLB\T3oodle\Domain\Permission\PollPermission

• Also all permissions defined in PollPermission dispatch an own signal

\FGTCLB\T3oodle\Domain\Repository\PollRepository

• findPolls Allows you to modify query constraints

Register a slot

To register a slot, you just need to add the following PHP code in ext_localconf.php of a TYPO3 extension:

/** @var \TYPO3\CMS\Extbase\SignalSlot\Dispatcher $signalSlotDispatcher */
$signalSlotDispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\SignalSlot\Dispatcher::class);
$signalSlotDispatcher->connect(
    \FGTCLB\T3oodle\Controller\PollController::class,
    'vote',
    \Vendor\MyExt\Slots\MyCustomSlots::class,
    'vote'
);

Writing the slot

The method you define as slot requires all arguments, passed by dispatcher. To identify the correct arguments, search in t3oodle code for ->dispatch(__CLASS__.

For example the arguments passed to vote action slot are:

[
    'vote' => $vote,
    'isNew' => !$vote->getUid(),
    'settings' => $this->settings,
    'continue' => true,
    'caller' => $this
]

So, this is how the slot method signature must look like:

use FGTCLB\T3oodle\Domain\Model\Vote;

final class MyCustomSlots
{
    public function vote(\FGTCLB\T3oodle\Domain\Model\Vote $vote, bool $isNew, array $settings, bool $continue, PollPermission $caller): array
    {
        // TODO: implement me
        return [
            'vote' => $vote,
            'isNew' => $isNew,
            'settings' => $settings,
            'continue' => $continue,
            'caller' => $caller,
        ];
    }
}

Also, the slot needs to return the arguments in same order, with keys prefixed!
