在 woocommerce 结帐页面自定义字段中添加日期

我正在尝试在 woocommerce 结帐页面中添加自定义选择选项。它正在添加额外的字段，但我想在选择选项的值中添加日期。

有什么解决办法吗？

这是我在主题 function.php 中添加的代码

$today = new DateTime();
$tomorrow = new DateTime();
$tomorrow->modify('+1 day');
$dayAfterTomorrow = new DateTime();
$dayAfterTomorrow->modify('+2 day');

add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );

function my_custom_checkout_field( $checkout ) {
    echo '<div id="my_custom_checkout_field"><h2>' . __('My Field') . '</h2>';

    woocommerce_form_field( 'my_field_name', array(
        'type'          => 'select',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Fill in this field'),
        'placeholder'   => __(''),
        'options'     => array(
          'Today' => __("This should be today's date"),
          'Tomorrow' => __('This should be tomorrow date'),
          'Day After Tomorrow' => __('This should be Day After Tomorrow Date')
        )), $checkout->get_value( 'my_field_name' ));
    echo '</div>';
}

Using date() and strtotime()你可以设置options如下：

add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );

function my_custom_checkout_field( $checkout ) {
    echo '<div id="my_custom_checkout_field"><h2>' . __('My Field') . '</h2>';

    $today = strtotime('today');
    $tomorrow = strtotime('tomorrow');
    $dayAfterTomorrow = strtotime('+2 days');

    woocommerce_form_field( 'my_field_name', array(
        'type'          => 'select',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Fill in this field'),
        'placeholder'   => __(''),
        'options'     => array(
            date( 'yyyy-mm-dd', $today ) => date( get_option('date_format'), $today ),
            date( 'yyyy-mm-dd', $tomorrow ) => date( get_option('date_format'), $tomorrow ),
            date( 'yyyy-mm-dd', $dayAfterTomorrow ) => date( get_option('date_format'), $dayAfterTomorrow ),
        )));
    echo '</div>';
}

这将允许您稍后按照格式保存日期年-月-日。我写了一篇教程自定义结账字段 https://www.kathyisawesome.com/woocommerce-customize-checkout-fields/您可能会发现有用。
