Helo,
how write this correctly
{foreach from=$category item = parent}
{foreach from=categoriesChild($parent.parent_id) item=cat}
do somthing
{/foreach}
{/foreach}
categoriesChild is function who get categorys from database where parent_id. How write this correct.
If be only php then be easy :). This is part of modifikation CMS made simple, blog module
