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

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

$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 'bottom'.

Default: 'bottom'

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).
