Adds a rewrite rule that transforms a URL structure to a set of query vars.

Description

Any value in the $after parameter that isn’t ‘bottom’ will result in the rule being placed at the top of the rewrite rules.

Parameters

$regex

(string) (Required) Regular expression to match request against.

$query

(string|array) (Required) The corresponding query vars for this rewrite rule.

$after

(string) (Optional) Priority of the new rule. Accepts 'top' or 'bottom'.

Default value: 'bottom'

More Information

add_rewrite_rule() allows you to specify additional rewrite rules for WordPress. It is most commonly used in conjunction with add_rewrite_tag() (which allows WordPress to recognize custom post/get variables).
