Set any ACF image field to automatically tie into the posts featured image

Are you looking for a way to streamline the process of managing featured images in your WordPress site? With a simple solution called _thumbnail_id, you can easily connect any Advanced Custom Fields (ACF) image field to the post’s featured image. In this article, we’ll explore how to implement this technique and enhance the intuitive nature of your site’s backend.

When working on a client’s site, ensuring a smooth user experience is crucial. By hiding the “Featured Image” option from your custom post type using a plugin like CPTUI, you can eliminate confusion and consolidate image management. Then, create an ACF image field with the field name _thumbnail_id.

By leveraging this naming convention, the ACF image field will automatically link to the post’s featured image. Now, whenever you upload or select an image in the ACF field, it will be synced with the featured image, simplifying the process of managing and updating visuals across your site.

By adopting this method, you can enhance the intuitiveness of your site’s backend and provide a seamless experience for your clients and content managers. Give it a try and enjoy the streamlined image management process in WordPress.
