I would like to display X recent products, randomly sorted, using a Woocommerce shortcode or a PHP function.
This shortcode...
[recent_products per_page="16" columns="4" orderby="rand"]
...displays 16 random products from the entire catalog (not the 16 last products randomly sorted).
Even if my Woocommerce settings specify that the default sorting is random, using this shortcode...
[recent_products per_page="16" columns="4"]
...displays the last 16 products ordered by date.
[recent_products per_page="16" columns="16" orderby="rand" order="ASC"]
I am not sure but could you please try this code?
