Signal Slots

The are two signals used in the extension, those signals are used to assign data to the Fluid Template forms.

Signal	Description
addFirstStepViewVariables	Assign data to first form
addSecondStepViewVariables	Assign data to second form

ext_localconf.php

Register signal slots as follow …

use TYPO3\CMS\Core\Utility\GeneralUtility;
use TYPO3\CMS\Extbase\SignalSlot\Dispatcher;

$signalSlotDispatcher = GeneralUtility::makeInstance(Dispatcher::class);
$signalSlotDispatcher->connect(
   \Oktopuce\SiteGenerator\Controller\SiteGeneratorController::class,
   'addFirstStepViewVariables',
   \Oktopuce\SiteGeneratorCustomized\Slot\SiteGeneratorSlot::class,
   'addFirstStepViewVariables'
);

SiteGeneratorSlot.php

… and assign needed variables.

namespace Oktopuce\SiteGeneratorCustomized\Slot;

use TYPO3\CMS\Core\Utility\GeneralUtility;
use TYPO3\CMS\Extbase\Object\ObjectManager;
use TYPO3\CMS\Extbase\Persistence\Generic\Typo3QuerySettings;
use TYPO3\CMS\Extbase\Domain\Repository\FrontendUserRepository;

class SiteGeneratorSlot
{

    /**
     * Add more variable for first step view
     *
     * @param array &$viewVariables The variables array with already assigned variables
     *
     * @return void
     */
    public function addFirstStepViewVariables(array &$viewVariables): void
    {
        /** @var ObjectManager $objectManager */
        /** @var FrontendUserRepository $frontendUserRepository */
        /** @var Typo3QuerySettings $typo3QuerySettings */
        $objectManager = GeneralUtility::makeInstance(ObjectManager::class);
        $frontendUserRepository = $objectManager->get(FrontendUserRepository::class);
        $typo3QuerySettings = $objectManager->get(Typo3QuerySettings::class);

        $typo3QuerySettings->setRespectStoragePage(false);
        $frontendUserRepository->setDefaultOrderings([
            'name' => \TYPO3\CMS\Extbase\Persistence\QueryInterface::ORDER_ASCENDING
        ]);
        $frontendUserRepository->setDefaultQuerySettings($typo3QuerySettings);

        $feUsers = $frontendUserRepository->findAll();

        $viewVariables['feUsers'] = $feUsers;
    }

}

In this example, we assigned feUsers variable to first Fluid Template form.
