Add additional pages to wordpress yoast seo sitemap xml programatically

Question

. I have a Wordpress site where the Yoast Seo plugin has been installed, titles, descriptions have been added, I could also manage to change the title tag, canonical url generated by it with the wpseo- filters.

The sitemap xmls are also generated fine, but I would need to add additional pages to it. We have a search page on the site, we search by a rental custom post type. Rentals can be searched by location. The search page is eg.: /rentals.

I have done a redirection for the urls: /rentals/budapest /rentals/hungary ... there are more locations. so they go to the rentals page, where I set the search parameters, I have changed the canonical urls of these pages, but I would like to add these pages to the xml sitemap also. The problem is that these page do not exist in the database.

Is there a filter that I coul use to add these pages to the sitemap.xml in Yoast Seo plugin?

Answer 1

use the wpseo_do_sitemap_ filter a custom sitemap is created if you use this to add
custom sitemap xml to sitemap index page we need to use 'wpseo_sitemap_index' filter
