Mobile versionIch habe eine Datei zum Hochladen einer Datei erstellt. Sie funktioniert wie erwartet, ein zweimaliges Aufrufen auf derselben Seite jedoch nicht funktioniert (der zweite Datei-Upload funktioniert nicht), ich teile hier meinen Beispielcode. Helfen Sie mir bitte dabei? - Das zweimalige Aufrufen der HTML-Formulare verursacht Probleme beim Hochladen der zweiten Formulardatei.
