Custom data for `PLL_Language`

  • Hello Polylang,

    In Polylang v3.3, the PHP attribute #[\AllowDynamicProperties] was added to the PLL_Language class to allow properties to be dynamically added in order to accommodate PHP 8.2’s deprecation of dynamic properties.

    In Polylang v3.4, this PHP attribute was removed. Furthermore, the hook pll_language_list has been deprecated in favour of a new hook pll_additional_language_data which is limited to a handful of official properties (home_url, search_url, page_on_front, page_for_posts).

    Since Polylang v2, we had been using the PLL_Language instances, via the hook pll_language_list, to add custom data—specifically, to store the translated page IDs for a custom “page for <custom post type>” feature we built.

    With the changes introduced in Polylang v3.4, this hinders our solution.

    Is there an alternative mechanism within Polylang that we could use or will we have to implement a new solution?

    Thanks,
