Enable Datepicker in a WooCommerce Checkout custom text field - php

Question

In WooCommerce, I can get a field hooked into my WooCommerce cart page & showing up OK using the following in my theme's (Storefront) functions PHP:
<?
// 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']));
}
?>
However, the datepicker widget is not initiated when you click into the field. I know the following code is required in the header for JQuery to work:
<script>
$( function() {
$( "#datepicker" ).datepicker(); } );
</script>
This did not work for me, so I thought to put this function into the checkout.js file in Storefront theme, but the added field didn't have calendar widget functionality.
There's a lot of .js in the them do I need to start a new one for includes?

Answer 1

First you will need to:
Enqueu main jquery-ui datepicker script
Change your custom script starting it with jQuery(function($){ instead of $(function(){ …
So to enable datepicker for your custom text field your code will be:
// 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>';
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
Tested and works. On storefront theme you will get that:
You may need to style it…

Just an update that this is no longer necessary. With Woocommerce you can simply change the style to 'date' and it deals with the rest for you - yahoo!
