How to omit fields programmatically in NF3?

    with NF 2.9, we used to omit a field completely from a form with (for example we don’t want to show Name + Email at all if user is logged in):

    add_filter('ninja_forms_display_fields_array', 'dpcontent_filter_ninja_form_fields', 10, 2);

function dpcontent_filter_ninja_form_fields($field_results, $form_id) { 
   unset($field_results[$x]); // where x is name / email

    So I now try and do this with NF3 (but line below breaks form – it does not even appear at all):

    add_filter('ninja_forms_display_fields', 'dpcontent_nf_display_fields', 10, 1);

function dpcontent_nf_display_fields($fields) {    
    unset($fields[2]); // this line breaks the form, commenting it fixes form but how to remove field from form?
    
    return $fields;
}

    @gvanto check the format of the passed $fields parameter, as it may have changed.

    hey @bkjohnson90,

    I’ve looked at the structure of the $fields parameter, (debug output below), it’s fairly straightforward.
    unset-ing an array element (each element corresponding to a field object) used to work (in NF 2.9.7) – field would simply not appear (which is desired behavior).

    In NF3 it breaks entire form (form not appearing at all).

    Will message you on slack, thanks.
