This thread is resolved. Here is a description of the problem and solution.
Problem:
The customer wants to set a custom field as the featured image for an entire custom post type. They are looking for a solution to establish this custom field globally for each post, as they did not find an existing feature in the documentation that meets this requirement.
Solution:
We informed the customer that there is no built-in feature within Toolset to directly set a custom field as the featured image. However, we provided a workaround involving the following steps:
Use the save_post action hook to trigger a PHP function when a post is saved.
Use the get_post_meta function to retrieve the custom image field value.
Retrieve the remote image file using cURL.
Save the image into the WordPress media library using wp_insert_attachment.
Set the media ID as the post's featured image using set_post_thumbnail.
Additionally, we shared a link to a forum post where a colleague provided a working example of code that runs through all posts of a specific custom post type, assigning a given custom field as the featured image.
