使用 woocommerce 预订动态询问人名。？

Question

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。

//* 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",

            "return" => true,

            "value" => "",

            "required"      => true,

            "label" => __( "Naam" )

            )

        );

        $html .= woocommerce_form_field( "participant_details[$i][email_address]", array(

            "type" => "email",

            "return" => true,

            "value" => "",

            "required"      => true,

            "label" => __( "Emailadres" )

            )

        );

    }

    return $html;

}

}
