This is an extension for modmore's Commerce.
This module allows an order to switch between inclusive and exclusive tax modes during checkout based on a session variable, and provides a custom product type called DynamicTaxModeProduct that allows setting both normal (inclusive) pricing and business (exclusive) pricing. The pricing shown to the customer depends on the tax mode currently active.
It is available under the MIT License.
Requirements:
- Commerce 1.5+
- PHP 7.4+
To use, install the package from the modmore package provider, and enable the module under Extras > Commerce > Configuration > Modules.
The tax mode changes between exclusive and inclusive depending on a session value. The default
key for the session variable is commerce_dynamictaxmode. If you would like to change it to something
else, you can set it in the module configuration window. Commerce > Configuration > Modules.
Create a new product with the type DynamicTaxModeProduct, or edit an existing product and
change to that type. Click on the pricing tab, and you'll see fields for both normal pricing and business
pricing. Enter the prices and hit save.
If no session variable is set, Dynamic Tax Mode Products will fall back to using the global system setting
commerce.tax_calculation.
Use your custom session key, or the default commerce_dynamictaxmode. The value should be set as either inclusive or exclusive.
A basic snippet on a product page might be one way of setting the session variable. e.g.
<?php
$_SESSION['commerce_dynamictaxmode'] = 'inclusive';
return '';
Public methods
DynamicTaxModeProduct includes two public methods to assist with getting and saving business pricing programmatically:
getBusinessPricing(comCurrency $currency): ?ItemPricingInterfacesaveBusinessPricing(ItemPricingInterface $pricing): bool
These work the same as the default getPricing and savePricing methods for the standard price.
