WP Page for post type

WP Page for post type Select a page to act as the archive of a custom post type. The post type's archive slug is rewritten to match the selected page's permalink. Multilingual (Polylang) support When the Polylang plugin is active, the archive rewrite rules are generated per language: Active languages are enumerated via plllanguageslist(). For each language, the translated page is resolved via pllgetpost($pageForPostType, $lang). Languages without a translation are skipped. The slug is built from the translated page's permalink (with the language context switched via pllswitchlanguage) so URLs like /en/books/ and /sv/bocker/ are produced for their respective languages. Each rewrite rule includes the lang query variable so Polylang can resolve the correct language content on the archive request. In single-language installations (Polylang inactive) the original behaviour is preserved. Note: After activating/configuring Polylang or changing the "page for post type" setting, flush rewrite rules (Settings → Permalinks → Save, or wp rewrite flush).
