Custom Product Delivery Dates

Customising the Plugin

To you these snippets, make sure you’re using a custom child theme, then paste them into functions.php.

Custom Styles

Include a custom mini-stylesheet on single product pages that use the date chooser.

function custom_delivery_dates_enqueue_scripts() {
	$base_uri = get_stylesheet_directory_uri();
	$theme_version = wp_get_theme()->get('Version');

	if (function_exists('cpdd_are_custom_delivery_assets_required') && cpdd_are_custom_delivery_assets_required()) {
		wp_enqueue_style(
			'child-cpdd',
			get_stylesheet_directory_uri() . '/custom-delivery.css',
			null,
			$theme_version
		);
	}
}
add_action('wp_enqueue_scripts', 'custom_delivery_dates_enqueue_scripts');

…and add your custom styles into “custom-delivery.css”.

Dynamically Prevent Delivery Dates

This snippet will prevent Mondays from being available for deliveries.

/**
 * Given an input date (yyyy-mm-dd), return whether or not that date is
 * blocked-out of the delivery date picker as unavailable.
 */
function custom_cpdd_is_delivery_date_blocked($is_blocked, $date_string) {
	$date = new DateTime($date_string, wp_timezone());

	// PHP DateTime formatting:
	// https://www.php.net/manual/en/datetime.format.php
	$day_of_week = intval($date->format('N'));

	// Block Mondays
	if ($day_of_week == 1) {
		$is_blocked = true;
	}

	// More custom date-blocking conditions...
	// ...
	// ...

	return $is_blocked;
}
add_filter('cpdd_is_delivery_date_blocked', 'custom_cpdd_is_delivery_date_blocked', 10, 2);
