WooCommerce next day order delivery

How to use WooCommerce to only allow next day delivery if before 1pm and day after tomorrow if ordered after 1pm. For a client, we were working as WooCommerce developers. One of the problem was this simple request.

We tried to find a switch for this in settings but couldn’t. We also didn’t want to install a whole WooCommerce plugin for this small functionality. So ended up writing this simple code. You may use it in the functions.php to set WooCommerce for next day delivery.

add_action( 'woocommerce_thankyou', 'custom_woocommerce_orderlordapi' );
function custom_woocommerce_orderlordapi( $order_id ) {

	// Lets grab the order
	$order = wc_get_order( $order_id );

	/**
	 * Put your tracking code here
	 * You can get the order total etc e.g. $order->get_total();
	 */
	 
	foreach ( $order->get_items() as $item_id => $order_item ) {
		//$custom_field = get_post_meta( $item_id, 'Delivery Date', true); 

		 
		 if(wc_get_order_item_meta( $item_id, 'Delivery Date', true )){
			  $delivery_date = wc_get_order_item_meta( $item_id, 'Delivery Date', true ); 
			   if(date('D') == 'Fri' && date('H') > 13) { 
				 $modified_delivery_date = date('Y-m-d', strtotime($delivery_date . ' +3 day'));
				 wc_update_order_item_meta($item_id, 'Delivery Date', $modified_delivery_date);
			  }
			  elseif(date('D') == 'Sat') { 
				 $modified_delivery_date = date('Y-m-d', strtotime($delivery_date . ' +2 day'));
				 wc_update_order_item_meta($item_id, 'Delivery Date', $modified_delivery_date);
			  }
			  elseif (date('H') > 13) {
				 $modified_delivery_date = date('Y-m-d', strtotime($delivery_date . ' +2 day'));
				 wc_update_order_item_meta($item_id, 'Delivery Date', $modified_delivery_date);
			  }
			  else{
				 $modified_delivery_date = date('Y-m-d', strtotime($delivery_date . ' +1 day'));
				 wc_update_order_item_meta($item_id, 'Delivery Date', $modified_delivery_date);
			  }
		 }
    }

}

This will set the WooCommerce delivery date based on the client settings. Let us know what you think.
