tl_calendar_events um featured erweitern, List operations
Hallo zusammen,
ich möchte den Contao Kalender um das Feld "featured" analog zu den Contao News erweitern. Dazu habe ich das DCA und Language-File erweitert. Das Speichern über das Formular funktioniert einwandfrei. Was leider nicht funktioniert, ist die List operation, also das togglen des Featured Status über das Featured-Icon in der Event-Übersicht. Ich habe soweit alles von der tl_news übernommen und angepasst, das Icon wird mir auch angezeigt und der Ajax-Request gefeuert, leider wird der Status in der DB aber nicht aktualisiert. Der Request und die Response (die ja auch bei tl_news keine Ausgabe erzeugt) sieht exakt so aus wie bei tl_news. Rufe ich den Toggle-Link händisch als GET Request auf, z.B. http://my.domain.com/contao?do=calendar&table=tl_calendar_events&id=1&& fid=1&state=&rt=XXXXXXX&ref=zzzz_xx, funktioniert das Updaten des Datensatz. Nur beim Ajax-Request wird die Funktion toggleFeatured() nicht aufgerufen. Wenn ich darin als erstes eine json encodierte Ausgabe mache, wird nichts ausgegeben, anders als bei der tl_news wenn ich mir dort etwas ausgeben lasse. Ich habe alles mehrfach mit der tl_news verglichen und finde einfach keinen Ansatz mehr.
Ich bin über jede Hilfe dankbar!
Anbei noch meine tl_calendar_events.php:
PHP-Code:
