[smarty] Pagina navigatie
Nu was ik benieuwd hoe de hun oplossing hebben bedacht voor de pagina navigatie die men vaak onderaan site zien zoals: < << 1 2 3 .... 8 9 10 >> >
Kan er iemand misschien wat tofs delen of uitleggen hoe diegene dit heeft gedaan. Ik was er wel nieuwsgierig naar.
EDIT: Is wel een iets andere variant.
