Thanks for writing back.
On my test website, I was able to achieve this, using a custom function attached to the 'wp_insert_post' hook.
( ref: https://developer.wordpress.org/reference/hooks/wp_insert_post/ )
This approach is much more reliable compared to the script method because it will keep the latitude and longitude values in separate custom fields in sync, no matter how a post is created or updated.
1. For the custom post type 'Books' (slug: book ), I added these custom fields:
a). Address type custom field with slug 'book-address'.
b). Single line type custom field with slug 'book-latitude'.
c). Single line type custom field with slug 'book-longitude'.
2. Next, I added the following custom function, which copies the lat/lon values from the address type custom field to the separate single line type custom fields, every time a 'Book' post is created or updated:
function custom_update_address_fields($post_id, $post, $update) {
// skip if post revision
if ( wp_is_post_revision( $post_id ) ) {
return;
}
// skip if post type is not the target post type 'book'
if ( get_post_type( $post_id ) != 'book' ) {
return;
}
// get the lat/lon values from the address type custom field 'book-address'
$address_field_val = types_render_field("book-address", array( 'item' => $post_id, 'format' => 'FIELD_LATITUDE,FIELD_LONGITUDE' ));
// If the address field value is not empty
if(!empty($address_field_val)) {
// Explode the lat and lon values
$address_field_val_arr = explode(',', $address_field_val);
// Update the lat and lon values in the separate custom fields
update_post_meta( $post_id, 'wpcf-book-latitude', $address_field_val_arr[0] );
update_post_meta( $post_id, 'wpcf-book-longitude', $address_field_val_arr[1] );
}
}
add_action( 'wp_insert_post', 'custom_update_address_fields', 9999, 3 );

Please adjust the custom post type and custom field slugs in the code, as used on your website.
