Håller på att försöka lära mig att bygga en php tabell med sid uppdelning av resultat och hittade en sida med kod, fast för mysql och inte mysqli. (Använder mysqli till tidigare anslutning till mysql servern.) Lyckades få till sidan som visar alla resultat i tabellen, men när man kommer till sidan som skall visa ett antal ur tabellen, för att sen visa resterande uppdelat på flera sidor fattar jag inte hur.
