Uncached Functions

WordPress core has a number of functions that, for various reasons, are uncached, which means that calling them will always result in an SQL query. Below, we outline some of these functions. We have a helper file with cached versions of some of the functions, which is automatically available to you.

• get_posts()
  • Unlike WP_Query, the results of get_posts() are not cached via Advanced Post Cache.
  • Use WP_Query instead, or set 'suppress_filters' => false
• wp_get_post_terms() and wp_get_object_terms()
  • Use get_the_terms() along with wp_list_pluck to extract the IDs
• get_category_by_slug()
  • Use wpcom_vip_get_category_by_slug() instead
• get_term_by()
  • Use wpcom_vip_get_term_by() instead
• get_cat_ID()
  • Use wpcom_vip_get_term_by() instead
• get_page_by_title()
  • Use wpcom_vip_get_page_by_title() instead
• get_page_by_path()
  • Use wpcom_vip_get_page_by_path() instead
