Title: Random sort & pagination – duplication & missing posts Last modified: December 9, 2022 --- # Random sort & pagination – duplication & missing posts * Resolved [medcourse](https://wordpress.org/support/users/medcourse/) * (@medcourse) * [3 years, 6 months ago](https://wordpress.org/support/topic/random-sort-pagination-duplication-missing-posts/) * Hi, * I use filter everything for a custom post type archive, to help junior doctors find online courses. This currently appears in pagination format (kadence theme pro) but will move to infinite scroll. * I currently sort by random as default, as I cannot be seen to favour certain ( 3rd party) courses over others. The problem is that with pagination & infinite scroll, the 2nd and 3rd pages just randomise again from the whole sample of courses, rather than randomising everything excluding the pages which have already been viewed. * This means that posts are duplicated, with some posts missing. * Is there a way around this? What I want is: * Page 1: 12 random posts from the sample of 36 Page 2: 12 random posts from the 24 posts which have not yet been showed page 3: 12 random posts from the 12 posts which have not yet been showed. * If there is nothing in the works for this, I’d appreciate any direction to give a WordPress dev to fix this issue. * Thanks! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Frandom-sort-pagination-duplication-missing-posts%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 2 replies - 1 through 2 (of 2 total) * Plugin Author [stepasyuk](https://wordpress.org/support/users/stepasyuk/) * (@stepasyuk) * [3 years, 5 months ago](https://wordpress.org/support/topic/random-sort-pagination-duplication-missing-posts/#post-16280886) * Hi [@medcourse](https://wordpress.org/support/users/medcourse/) * Thank you for using Filter Everything plugin. * You can apply your ordering to the filtered WP_Query via hook `wpc_filtered_query_end` that fires after filtering parameters were applied to a WP_Query. And also your Infinite scroll feature should use filtered page URL for example [https://medcourse.co.uk/online/course-list/?ordr=random](https://medcourse.co.uk/online/course-list/?ordr=random) to get correct filtered/sorting results from your site. - This reply was modified 3 years, 5 months ago by [stepasyuk](https://wordpress.org/support/users/stepasyuk/). * Thread Starter [medcourse](https://wordpress.org/support/users/medcourse/) * (@medcourse) * [3 years, 5 months ago](https://wordpress.org/support/topic/random-sort-pagination-duplication-missing-posts/#post-16280996) * This goes way over my head but is very useful to pass to a wp dev – thank you! Just out of interest, how long would this take for a dev to implement (so I know how much to pay a freelancer)? * Cheers!
