EXT: sf_event_mgt erweitern: Registrierung direkt auf Detailseite

In diesem Beispiel ist der Vendor ‘Machwert’ und die Extension ‘theme’.

1. In die Datei ext_localconf.php der eigenen Extension die zu vererbende Klasse definieren:

<?php
declare(strict_types=1);
use Machwert\Theme\Xclass\NewEventController as NewEventControllerXclass;
use DERHANSEN\SfEventMgt\Controller\EventController;
defined('TYPO3') or die();
$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'][EventController::class] = [
    'className' => NewEventControllerXclass::class
];

2. NewEventController.php anlegen und dort die $this→settings['singleEvent'] über den URL-Event-Parameter festlegen. Dann die jeweilige Elternfunktion der Originalklasse aufrufen.

<?php
declare(strict_types=1);

3. Bei Composer Installation in der composer.json darauf achten, dass die Extension Klassen geladen werden.

"autoload": {
        "psr-4": {
            "Machwert\\Theme\\": "Classes"
        }
    },

4. Extension per Composer deinstallieren und danach wieder installieren, damit die autoload Klassen registriert werden. Folgende Shell-Befehle ausführen:

composer remove Machwert/theme
composer req Machwert/theme
