Jak vypadá kód stojící za těmito stránkami?

Tyto stránky jsou postaveny na Zend Frameworku s rozdělením na modely, šablony prezentační vrstvy a controllery, které vše řídí.

 

Jako Model posloužila ORM knihovna Doctrine.

 

Pro View jsem použil vlastní šablonovací systém PSTL, který je podobný základnímu JSTL známému z Javy doplněnému o tagy z knihovny Stripes.

        <c:import url="photogallery.psp"/>
        </s:layout-component>
    </s:layout-render>
</s:layout-definition>

 

Jako Controller jsem použil ActionBean z mé PHP knihovny Stripes, který rozšiřuje standardní Zend_Controller o některé vhodné vlastnosti.
