Dus de view zal zoiets als dit worden:

en in de view:
Code (php)

maar wat gebeurt er nu met $this->clients in de view als er nog niet gepost is? want dan bestaat deze natuurlijk nog niet!

Wil je bij 1 of meer resultaten de resultaten tonen en anders niet en de rest van de view is gelijk dan hoort dat in de view thuis.
Wil je de 3 recentste resultaten tonen in de sidebar dan krijg je te maken met 2 views en 2 controllers die elk hun eigen view aanroepen, maar dat is hierbij niet van toepassing.
