Nou heb ik 2 problemen.
1: Als ik de pagina refresh (F5 bijvoorbeeld), dan wordt de data opgeslagen in de database, dus krijg ik een lege regel.

2: Alles wordt opgeslagen in de database, behalve de locatie van het bestand. Wat doe ik fout?

Post alleen relevante code. Beetje onzinnig om 412 regels te posten.

Probleem 1: je INSERT-query staat helemaal bovenin je code, zonder enige controle. Dus eerst de input controleren, dan pas INSERT in de database.

Probleem 2: je moet (denk ik) de locatie van het bestand ook meeposten.
