OpenGraph image url from category pages for functions.php

  • Hi

    I have a custom social share button on category pages.

    I implement it using functions.php but don’t know how to get og:image URL from category page. I need to get it for “media” of Pinterest share button URL:
    1) category image URL if it is manually added in?Social Media Preview Snippet for Facebook
    2) or if there is no such image, then use the global image URL from?Global Meta / OpenGraph Thumbnail


    <a href="https://pinterest.com/pin/create/button/?url=<?php echo $category_url; ?>&media=<?php echo $og_image_encoded; ?>&description=<?php echo $category_title_encoded; ?>"

    As, far as I understand I need to deal with rank_math/opengraph/facebook/og_image_secure_url or rank_math/opengraph/facebook/og_image but how to get it from category pages and what function to use I don’t understand.

    Thanks for help in advance!
