Hi everyone,

i need to build a form which will be able to fill select box with data from other field and i found this really simple code:

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');

And everything is fine until I add other filter which try to get data from other field on this same page:

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');

Then i got 503 error and this cames up in the log file:

Should I execute some extra function before trying get field data ?
