具有多个输入的自定义重力形式字段

I have been working on a Gravity Forms extension for a client. The concept is to add a new field type with 4 inputs. I have tried about 10 different variations on how people build custom gravity form fields, but I keep running into the same issue.

When creating a custom field, if I use only 1 input under the naming convention of input_{field_id} the form will save and validate properly. But the moment I try to add more than one field using the names input_{field_id}.{i} just like the built in fields the form will no longer save my data.

<?php if ( ! class_exists( 'GFForms' ) ) { die(); }

class GF_Field_Attendees extends GF_Field {

    public $type = 'attendees';

    public function get_form_editor_field_title() { return esc_attr__( 'Attendees', 'gravityforms' ); }

    public function get_form_editor_button() {
        return array(
            'group' => 'advanced_fields',
            'text'  => $this->get_form_editor_field_title(),
            'onclick'   => "StartAddField('".$this->type."');",
        );
    }

    public function get_form_editor_field_settings() {
        return array(
            'conditional_logic_field_setting',
            'prepopulate_field_setting',

I have spend about 20 hours trying different fixes and searching the internet to get this working, with no luck to show for it. At one point I was able to get the form fields to save using a different method (see below), but I could not make the field required or use conditional login on it, which is a must.

$group_title = "Attendees";
$group_name = "attendees";
$group_fields = array(
    'attendee_first' => 'First Name',
    'attendee_last' => 'Last Name',
    'attendee_email' => 'Email',
    'attendee_phone' => 'Phone'
);
$group_values = array();

add_filter('gform_add_field_buttons', add_field);
function add_field($field_group)
{
  global $group_title, $group_name;

  foreach ($field_group as &$group) {

    if ($group['name'] == 'advanced_fields') {
      $group['fields'][] = array (
        'class'     => 'button',
        'value'     => __($group_title, 'gravityforms'),
        'onclick'   => "StartAddField('".$group_name."');",
        'data-type' => $group_name
      );
      break;
    }
  }

  return $field_group;
}

add_filter('gform_field_type_title', add_field_title, 10, 2);
function add_field_title($title, $field_type)
{
  global $group_title, $group_name;

  if ($field_type == $group_name) {
    $title = __($group_title, 'gravityforms');
  }

  return $title;
}

add_filter('gform_field_input', 'render_fields', 10, 5);
function render_fields($input, $field, $value, $entry_id, $form_id)
{
  global $group_name, $group_fields;

  if ($field->type == $group_name)
  {
    $i = 1;
    $input = '<div class="ginput_complex ginput_container">';
    foreach ($group_fields as $key => $val) {
        $input .= '<span id="input_'.$field['id'].'_'.$form_id.'_'.$i.'_container" class="name_suffix ">';
            $input .= '<input type="text" name="input_'.$field['id'].'_'.$i.'" id="input_'.$field['id'].'_'.$form_id.'_'.$i.'" value="'.$value[$field['id'].'.'.$i].'" class="'.esc_attr($key).'" aria-label="'.$val.'">';
            $input .= '<label for="input_'.$field['id'].'_'.$form_id.'_'.$i.'">'.$val.'</label>';
        $input .= '</span>';
        $i ++;
        if ($i % 10 == 0) { $i++; }
    }
    $input .= '</div>';
  }

  return $input;
}

add_action('gform_editor_js_set_default_values', set_default_values);
function set_default_values()
{
  global $group_title, $group_name, $group_fields;
  ?>
  case '<?php echo $group_name; ?>' :
    field.label = '<?php _e($group_title, 'gravityforms'); ?>';
    field.inputs = [
        <?php
        $i = 1;
        foreach ($group_fields as $key => $val) { ?>
            new Input(field.id + 0.<?php echo $i; ?>, '<?php echo esc_js(__($val, 'gravityforms')); ?>'),
        <?php
            $i++;
            if ($i % 10 == 0) { $i++; }
        } ?>
    ];
    break;
  <?php
}

add_filter( 'gform_entry_field_value', 'category_names', 10, 4 );
function category_names( $value, $field, $lead, $form )
{
  global $group_name, $group_values;

  if($field->type == $group_name)
  {
    $array = array();
    $output = "";
    foreach($field->inputs as $input)
    {
      $array[$input['label']] = $value[$input['id']];

      $output .= "<strong>".$input['label'].":</strong> ";
      $output .= $value[$input['id']]."<br>";
    }
    $group_values[] = $array;

    return $output;
  }

  return $value;
}

If anyone can help me with either issue, it would be greatly appreciated.

    After working with the Gravity Forms support team for a few days, we were able to come up with this solution. Everything seems to be working now. Hope this helps someone in the future.
