(type)_template_hierarchy filter-hook . WP 4.7.0

Filters the list of template filenames that are searched for when retrieving a template to use.

The dynamic portion of the hook name, $type, refers to the filename -- minus the file extension and any non-alphanumeric characters delimiting words -- of the file to load. The last element in the array should always be the fallback template for this query type.

• 404_template_hierarchy
• archive_template_hierarchy
• attachment_template_hierarchy
• author_template_hierarchy
• category_template_hierarchy
• date_template_hierarchy
• embed_template_hierarchy

• paged_template_hierarchy
• privacypolicy_template_hierarchy
• search_template_hierarchy
• single_template_hierarchy
