I want to add some functionality to my site. I used to just have a few categories, but as I wrote more, I wanted to sub-categorize a bit. So now, I have a handful of parent categories, and under (most of) these I have one or more child categories. In some cases this goes three or four deep.
But, so the category list isn’t too long, I only show the parent categories in the sidebar. What I want is that when a category page is shown, at the top is a list of the child categories.
I can (relatively) easily find out if I am viewing a category page:
{if $smarty.server.REQUEST_URI|truncate:10::1 == '/category/'}
I can also quite easily find the name of the category, but not the id. This is what I need for creating the category list.
I’ve just had a thought. [Checks something]. The following displays the info that is sent to the server:
{foreach from=$smarty.server.argv item=var}
{$var}
{/foreach}
I was hoping it would give the category id. But it doesn’t, only the name. Back to the drawing board.
