I've created my own Custom Post Type called 'products'. I have also registered by own custom taxonomies for the CPT - a custom category type (so it is separate from the default wp posts) and also its own tag system.
Then I registered a shortcode for displaying the CPT. However I am having trouble filtering the display of the posts using the category and tag parameters.
UPDATE It appears as though my custom taxonomy 'type' was reserved and was not letting me output the CPT, it was defaulting back to generic posts. So I have updated my code to call it 'product_type' and the CPTs are displaying.
HOWEVER, I am not able to filter them via category or using the custom taxonomy:
e.g. [ss-products product_type="Bends" orderby="name" order="ASC"]
If I attempt to filter, I return no results, I I use product_type="" it then displays all.
function ss_products_post_type() {
// Set UI labels for Custom Post Type
$labels = array(
'name' => _x( 'Products', 'Post Type General Name', 'generatepress' ),

Reset to default 0My biggest mistake was using a taxonomy named 'type'. Yes it messed everything up since it caused many conflicts (with soft fails, no error messages). I'm doing this on my localhost but somehow some changes did not come through instantly - had to log off, close and login again to see desired results.
