Für den ersten Fehler befindet sich das Fehler-Array außerhalb von foreah, sodass Sie den Fehler nicht für jede Datei löschen, und die einzufügende Abfrage befindet sich außerhalb von if that prüft Fehler und wird daher immer ausgeführt
Beim zweiten Fehler das gleiche, die Abfrage wird immer ausgeführt man muss prüfen ob die Datei hochgeladen ist.
