<?php // <~ don't add me in

add_filter( 'woocommerce_short_description', 'prefix_filter_woocommerce_short_description' );
/**

 */
function prefix_filter_woocommerce_short_description( $post_post_excerpt ) { 
    // make filter magic happen here... 
    if(! is_product() ) { // add in conditionals
        $text = $post_post_excerpt; 
        $words = 10; // change word length
        $more = ' […]'; // add a more cta
        
        $post_post_excerpt = wp_trim_words( $text, $words, $more );
    }
    return $post_post_excerpt; 
}; 

Still works, it’s not a short code though, code goes in functions file and template conditions need to be set as commented in code.

This doesn't work for me. I use this instead

This works, but it also limits the description on the category description on product category listing pages. How do I prevent this?

I also just noticed that the function doesn't get applied to post items in loops outside the main loop e.g. 'related products' or 'recently viewed'. How could I apply it to them too?
