Select current category slug

Hi There,

I’m working on a custom theme that’s using the TDO Tag fix plugin to allow for filtering posts based on category then tag.

In the theme, I’ve created a custom category template that then links through to the appropriate tag filed under each category – for example

Current Page URL:
https://xxx.com/category/

Link to tag filter:
https://xxx.com/category/?tag=blah

I need a way of being able to dynamically output the current category slug for use in linking through the tags.

Something like <?php echo get_query_var(‘slug’); ?>

Although obviously that doesn’t work (<?php echo get_query_var(‘tag_id’); ?> does for the tag ID though though for example)

I’ve spent a couple of hours looking for a solution to what I though was a pretty simple issue – maybe I’ve just overlooked something pretty simple.

Thanks!
