WooCommerce has a filter that can limit the words in a product short description field called ‘woocommerce_short_description‘ – coupled with an existing WordPress function ‘wp_trim_words‘ we can make the description any length to suit teasers, sliders etc and leave other areas where we want the full short description.
In the code snippet above we are using a conditional to apply this to any usage of the short description outside of a single product post, the filter uses the 1 parameter $post_post_excerpt which is assigned to $text, the $word count is set to 10 with a […] used as the $more value – these three parameters belong to wp_trim_words which is executed and returned back to $post_post_excerpt – which is now a 10 word product short description.
