Save_Post & get_post_meta

Hello everybody,

I cant get my function work. I searched some threats, and they say that it wont work.

I just want to transfer a custom field to post_excerpt if the post is saved or updated.

This is the code I found and tested, but it only works if I save the Post 2 times.

function my_function( $post_id ){
	
	// Only set for post_type = post!
	/*if ( 'citadela-item' !== $post->post_type ) {
		return;
	}*/
	
    if ( ! wp_is_post_revision( $post_id ) ){
		
 		// unhook this function so it doesn't loop infinitely
        remove_action('save_post', 'my_function');
		
		$address_to_excerpt = get_post_meta( $post_id, '_city_address', true );
     
        // update the post, which calls save_post again
        $my_args = array(
			'ID'           => $post_id,
			'post_excerpt' => $address_to_excerpt,
		);
        wp_update_post( $my_args );
 
        // re-hook this function
        add_action('save_post', 'my_function');
    }
}
add_action( 'save_post', 'my_function' );

Now I found this ACtion wp_after_insert_post but I dont understand how it works. there are no examples I understand. But it seems to be the right action.

Any suggestions to help?

Thanks,
Denis
