Hallo zusammen,
ich arbeite zurzeit an einer Quiz-Erweiterung und schlage mich mit einem seltsamen Problem herum. Ich habe eine Tabelle mit 3 Kindtabellen.
- tl_quiz
- tl_quiz_question
- tl_quiz_result
Wenn ich in tl_quiz_answer einen Eintrag erzeuge und dann den Quiz-Bereich verlasse, wird der Eintrag in tl_quiz_answer automatisch gelöscht. Der Eintrag ist nach dem Anlegen in der Datenbank vorhanden und kann auch per Toggle ein und ausgeblendet werden.
Wenn ich über "zurück" die Tabelle "tl_quiz_question" aufrufe und dann zu "tl_quiz_answer" zurück kehre, ist der Eintrag auch weiterhin vorhanden. Wenn ich aber zwei Mal auf "zurück" klicke, also bei "tl_quiz" lande, wird der Eintrag in "tl_quiz_answer" automatisch gelöscht.
Hat jemand dafür eine Erklärung?
