Title: Callback function for slider Last modified: March 7, 2020 --- # Callback function for slider * Resolved [emj](https://wordpress.org/support/users/emj/) * (@emj) * [6 years, 2 months ago](https://wordpress.org/support/topic/callback-function-for-slider/) * Hi, * I am loading your fagsfacf slider in my wordpress post archive. e.g. i have post title, link the post, and a slider of images related that that post. * It looks great! However i am using the Ajax Load More (ALM) plugin to lazy load these posts on my archive page. The posts are lazy loading correctly, however the slider is not. * I contacted the ALM developer and he suggested I could fix it by adding a Callback function: [https://connekthq.com/plugins/ajax-load-more/docs/callback-functions/almcomplete/](https://connekthq.com/plugins/ajax-load-more/docs/callback-functions/almcomplete/) * Are you able to help me write this function? Unfortunately i cant get it working. * Can i email you my URL to preview what i mean? The archive page is live but behind a login. * Thank you!
