在woocommerce结帐页面自定义字段中添加日期

Question

I am trying to add custom select option in woocommerce checkout page. It is adding the extra field but I want to add the date in the value of the select option.

Is there any solution for this?

Here is the code I added in my theme function.php

$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>';
}

Answer 1

Using date() and strtotime() you can set the options as follows:

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>';
}

This will allow you to later on save dates as in the format YYYY-MM-DD. I wrote a tutorial on customizing the checkout fields that you may find useful.
