Load more then two other fields in load_field filter.

  • Hi everyone !

    I have this simple code to fill select box with data pulled from other field

    function acf_load_acti_field_choices( $field ) {
    
        // reset choices
        $field['choices'] = array();
    
        // if has rows
        if( have_rows('activities', 260) ) {
    
            // while has rows
            while( have_rows('activities', 260) ) {
    
                // instantiate row
                the_row();
                // vars
                $name = get_sub_field('name');
                $name2 = get_sub_field('title_2');
                $label = get_sub_field('subtitle');
                // append to choices
                $field['choices'][ sanitize_title($name.$name2) ] = $name." ".$name2;
    
            }
    
        }
    
        wp_reset_postdata();
    
        // return the field
        return $field;
    
    }
    
    add_filter('acf/load_field/name=activities_select', 'acf_load_acti_field_choices');
    

    Everything works find until I not try to do this some for other field. After adding other filter on load_field event with code like this:

    
    function acf_load_trainer_field_choices( $field ) {
    
        // reset choices
        $field['choices'] = [];
        if( have_rows('crew', 260) ) {
    
            // while has rows
            while( have_rows('crew', 260) ) {
    
                // instantiate row
                the_row();
                // vars
                $name = get_sub_field('name');
                // append to choices
                $field['choices'][ sanitize_title($name) ] = $name;
    
            }
    
        }
        // return the field
        return $field;
    
    }
    add_filter('acf/load_field/name=trainer_select', 'acf_load_trainer_field_choices');
    

    I got 503 code error and this cames up in the log file:

    [Thu Apr 04 12:27:50.853017 2019] [proxy_fcgi:error] [pid 14595:tid 140229314660096] [client XX.XX.XX.XX:58723] AH01067: Failed to read FastCGI header, referer: http://localhost/wp-admin/

    This behaviour is not related to any specific field. Problem exist only when I try load more than one field in filters. Should I execute some extra function before trying load other field ?
