Meerdere problemen bij het uploaden van foto's

Voor de eerste fout bevindt de foutenarray zich buiten de foreah, zodat u de fout niet voor elk bestand wist, en de in te voegen query bevindt zich buiten de als die fouten controleert, zodat deze altijd wordt uitgevoerd

Voor de tweede fout hetzelfde, de query wordt altijd uitgevoerd, u moet altijd controleren of het bestand is geüpload.
