在WooCommerce Checkout自定义文本字段中启用Datepicker

Question

在WooCommerce中,我可以将一个字段挂钩到我的WooCommerce购物车页面并在我的主题(店面)函数PHP中使用以下内容显示OK:

<?
            // ADD Custom Fields to Checkout Page
            /**
             * Add the field to the checkout
             **/

            add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');

            function my_custom_checkout_field( $checkout ) {

                date_default_timezone_set('America/Los_Angeles');
                $mydateoptions = array('' => __('Select PickupDate', 'woocommerce' )); 

                echo '<div id="my_custom_checkout_field"><h3>'.__('Delivery Info').'</h3>';

               woocommerce_form_field( 'order_pickup_date', array(
                    'type'          => 'text',
                    'class'         => array('my-field-class form-row-wide'),
                    'id'            => 'datepicker',
                    'required'      => true,
                    'label'         => __('Delivery Date'),
                    'placeholder'       => __('Select Date'),
                    'options'     =>   $mydateoptions
                    ),$checkout->get_value( 'order_pickup_date' ));

                echo '</div>';
            }

            /**
             * Process the checkout
             **/
            add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

            function my_custom_checkout_field_process() {
                global $woocommerce;

                // Check if set, if its not set add an error.
                if (!$_POST['order_pickup_date'])
                     wc_add_notice( '<strong>PickupDate</strong> ' . __( 'is a required field.', 'woocommerce' ), 'error' );
            }

            /**
             * Update the order meta with field value
             **/
            add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');

            function my_custom_checkout_field_update_order_meta( $order_id ) {
                if ($_POST['order_pickup_date']) update_post_meta( $order_id, 'PickupDate', esc_attr($_POST['order_pickup_date']));
            }
            ?>

但是,单击该字段时不会启动datepicker小部件.我知道JQuery工作头中需要以下代码:

<script>
$( function() {
$( "#datepicker" ).datepicker(); } );
</script>

这对我不起作用,所以我想把这个函数放到Storefront主题的checkout.js文件中,但添加的字段没有日历小部件功能.

其中有很多.js我需要为包含开始一个新的吗？

首先,您需要:

• Enqueu主jquery-ui datepicker脚本
• 更改自定义脚本jQuery(function($){而不是$(function(){...

因此,为了启用datepicker自定义文本字段,您的代码将是:

// Register main datepicker jQuery plugin script
add_action( 'wp_enqueue_scripts', 'enabling_date_picker' );
function enabling_date_picker() {

    // Only on front-end and checkout page
    if( is_admin() || ! is_checkout() ) return;

    // Load the datepicker jQuery-ui plugin script
    wp_enqueue_script( 'jquery-ui-datepicker' );
}

// Call datepicker functionality in your custom text field
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field', 10, 1);
function my_custom_checkout_field( $checkout ) {

    date_default_timezone_set('America/Los_Angeles');
    $mydateoptions = array('' => __('Select PickupDate', 'woocommerce' ));

    echo '<div id="my_custom_checkout_field">
    <h3>'.__('Delivery Info').'</h3>';

    // YOUR SCRIPT HERE BELOW 
    echo '
    <script>
        jQuery(function($){
            $("#datepicker").datepicker();
        });
    </script>';

   woocommerce_form_field( 'order_pickup_date', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'id'            => 'datepicker',
        'required'      => true,
        'label'         => __('Delivery Date'),
        'placeholder'       => __('Select Date'),
        'options'     =>   $mydateoptions
        ),$checkout->get_value( 'order_pickup_date' ));

    echo '</div>';
}

代码放在活动子主题(或主题)的function.php文件中,或者放在任何插件文件中.

经过测试和工作.在店面主题上,您将获得:

你可能需要设计风格......
