Adds a new permalink structure.

A permalink structure (permastruct) is an abstract definition of a set of rewrite rules; it is an easy way of expressing a set of regular expressions that rewrite to a set of query strings. The new permastruct is added to the WP_Rewrite::$extra_permastructs array.

When the rewrite rules are built by WP_Rewrite::rewrite_rules(), all of these extra permastructs are passed to WP_Rewrite::generate_rewrite_rules() which transforms them into the regular expressions that many love to hate.

The $args parameter gives you control over how WP_Rewrite::generate_rewrite_rules() works on the new permastruct.

$name string Required

Name for permalink structure.

$struct string Required

Permalink structure (e.g. category/%category%)

$args array Optional

Arguments for building rewrite rules based on the permalink structure.

• with_frontbool
  Whether the structure should be prepended with WP_Rewrite::$front.
  Default true.
• ep_maskint
  The endpoint mask defining which endpoints are added to the structure.
  Accepts a mask of:
  

  • EP_ALL
  • EP_NONE
  • EP_ALL_ARCHIVES
  • EP_ATTACHMENT
  • EP_AUTHORS
  • EP_CATEGORIES
  • EP_COMMENTS
  • EP_DATE
  • EP_DAY
  • EP_MONTH
  • EP_PAGES
  • EP_PERMALINK
  • EP_ROOT
  • EP_SEARCH
  • EP_TAGS
  • EP_YEAR Default EP_NONE.
• pagedbool
  Whether archive pagination rules should be added for the structure.
  Default true.
• feedbool
  Whether feed rewrite rules should be added for the structure. Default true.
• forcommentsbool
  Whether the feed rules should be a query for a comments feed. Default false.
• walk_dirsbool
  Whether the 'directories' making up the structure should be walked over and rewrite rules built for each in-turn. Default true.
• endpointsbool
  Whether endpoints should be applied to the generated rules. Default true.
