Behöver hjälp med att para databasvärden

Ok, jag fick det att fungera. Jag är inte säker på om det är den mest eleganta lösningen. Om någon vill höra av sig med förbättringar är jag helt beredd. Förhoppningsvis kommer detta att hjälpa någon som har liknande problem i framtiden.

Min sista artikel/produktslingafråga:
