我正在使用 woo commerce bookings 插件来预订旅行，但我想根据动态人数在结帐页面上单独获取每个人的类型名称。我发现堆栈溢出的帖子对我不起作用，它一直说未定义的偏移量 0 作为结帐页面上的错误。

我已经尝试过这个功能。

//* Add a new checkout field
add_filter( 'woocommerce_checkout_fields', 'ppp_filter_checkout_fields' );
function ppp_filter_checkout_fields($fields){
$fields['extra_fields'] = array(
'participant_details' => array(
    'type' => 'participant_details',
    'required'      => false,
    'label' => __( 'Participant Details' )
    ),
);

// Add a "persons" hidden input field
foreach( WC()->cart->get_cart() as $cart_item ) {
    $persons = $cart_item['booking']['_persons'][0];
}
echo '<input type="hidden" name="persons" value="' . $persons . '">';

return $fields;
}

//* Add the field to the checkout
add_filter( 'woocommerce_form_field_participant_details', 'ppp_filter_checkout_field_group', 10, 4 );
function ppp_filter_checkout_field_group( $field, $key, $args, $value ){
$op_cart_count = WC()->cart->get_cart_contents_count();

$items = WC()->cart->get_cart();

foreach($items as $item) {
    $person = $item['booking']['_persons'][0];
}

if ($person > 1) {

    $html = '';

    $html .= "<h3>Deelnemers</h3>";

    for ( $i = 1; $i < $person; $i++) {
        $counter = $i + 1;

        $html .= "Deelnemer ". $counter . "<br>";

        $html .= woocommerce_form_field( "participant_details[$i][full_name]", array(
            "type" => "text",

  // Add checkout custom text fields

   function add_checkout_custom_text_fields( $checkout) {

    $index++;
    // 2nd Loop through each unit related to item quantity
    for($i = 1; $i <= $cart_item['booking']['Adults']; $i++){

        woocommerce_form_field("Adult[$index][$i]", array(
