Hi there,
don´t know if the solution is obvious but I don´t find it:

I am looking for a solution to either show a certain branch of wordpress-categories as an ACF-Select-Field or to auto-add a post with a certain ACF-Value to a WP-category when saving the post (WP-category has also to be deselected when deselecting the ACF-value).

My goal:
Our posts can be in multible WP-categories of course. I wan´t force the author to select a leading category on each post wich I can display in lists etc.

Hello,

This is a question related to ACF, and not to the plugin itself, but here is a possible solution:

Use the hook acf/save_post (https://www.advancedcustomfields.com/resources/acf-save_post/) in order to manipulate the post behavior once saved. In your example:


add_action('acf/save_post', 'acf_save_post_category', 20)
function acf_save_post_category($post_id){
    
    // Target the specific post type: Post
    if(get_post_type($post_id) != 'post')
        return;
    
    // Get current post categories
    // Note: If using a custom post type & custom taxonomy, you must use wp_get_post_terms()
    $current_categories = get_the_category($post_id);
    
    // If categories are set: Stop
    if(!empty($current_categories))
        return;
    
    // No category is set. Set default category ID: 1
    // Note: If using a custom post type & custom taxonomy, you must use wp_set_object_terms()
    wp_set_post_categories($post_id, array(1));

}

This will check if a post hs no category, and set a default category ID if that’s the case.

Hope it helps!

Regards.
