The e-commerce industry continues to grow rapidly year over year, bringing more merchants online and driving larger profits. With that growth comes the increased need for rich content, innovative product merchandising, and integration into an ever increasing number of third party sales, marketing, and fulfillment tools. Drupal has always excelled as a platform for building unique customer experiences, and it continues to come into its own as an adaptive sales platform via projects like Drupal Commerce.

The taxation rules that come with Drupal Commerce out of the box calculate VAT or sales tax for each line item without any conditions, so every item in the order is taxed. This works for many situations but if you have items which need to be tax exempt you're in trouble. But there is a relatively painless way around it using some rules and fields.

To start with create a new field on your product entity called Tax Exempt. Set it to be a Boolean, single on/off checkbox.

Create a field called Tax Exempt

Make sure the default value is not checked, we don't want things to be tax exempt by default. Also remember to hide this field in the Manage Display settings.

Now we have to set up the taxation rules to handle this. Make sure the Tax and Tax UI modules are turned on. Two tax types will be enabled by default: VAT and Sales tax. We're going to start by setting up a generic sales tax. Right now we're going to charge this sales tax for everything. Realistically in the United States, you need to only collect sales tax in the state you're doing business in. For more on this topic check out another post in our Drupal Commerce Tax Series, Conditional State Sales Tax.

Create a new tax, we'll call it Generic Sales Tax. Give it a rate of .07, this translates to 7%.

Create a new generic tax rate

We can click configure component and add our conditions. First we need to bring the Tax Exempt field into scope. In Rules you have to check for a field before you can query it. Our first rule will be to get to the Product entity.

Condition: Entity has field.

Data selector: commerce-line-item
Field: commerce_product

Rule condition: entity has field commerce-product

This gives us access to the product through rules. Our next rule will give us access to the Tax Exempt field.

Condition: Entity has field

Data selector: commerce-line-item:commerce-product
Field: field_tax_exempt (or whatever you called your field)

Rule condition: entity has field Tax Exempt

Now that we have access to our Tax Exempt field we can make sure tax exempt items are not taxed.

Condition: Data to compare

Data selector: commerce-line-item:commerce-product:field-tax-exempt
Operator: Equals
Data value: (checked)
What this does is create a NOT Data comparison. So as long as the product does not have the Tax Exempt field checked tax will be calculated.

Rule condition: field Tax Exempt is not checked

With these conditions taken into account when calculating sales tax from a line item creating tax exempt products is as easy as checking a box. Here are all of the tax exempt conditions together.

All conditions for exempting products from taxation

Few month ago I developed  a simple module called Commerce Order2pdf and then I also added custom tokens as you can read from this post Custom token creation for Drupal 7 and now I reviewed this module a bit and planned to add views field handler (This means I can create custom view with download links). 

So how did I implemented this?

First step was to edit commerce_order2pdf.module file and add hook_views_api. So I could start working with views.

 * Implements hook_views_api().
function commerce_order2pdf_views_api() {
  return array(
    'api' => 3,
    'path' => drupal_get_path('module', 'commerce_order2pdf') . '/includes/views',

Next one was to create subdirectories includes/views into my commerce_order2pdf folder (module folder).

After this I had to tell views about my data structure.
So I did created new file /includes/views/commerce_order2pdf.views.inc and added hook_views_data.

 * Implements hook_views_data()
function commerce_order2pdf_views_data() {
  $data = array();
  $data['commerce_order']['order2pdf_link'] = array(
    'field' => array(
      'title' => t('Download pdf order'),
      'help' => t('Provide a simple link to download the order.'),
      'handler' => 'commerce_order2pdf_handler_field_order_pdf_link',
  return $data;

In this array I did extended commerce_order group and added field handler class callback.

Now we will add a new file commerce_order2pdf_handler_field_order_pdf_link.inc to includes/views folder.

 * Field handler to present an order pdf download link.
class commerce_order2pdf_handler_field_order_pdf_link extends commerce_order_handler_field_order_link {
  function construct() {

  function render($values) {
    $order = commerce_order_new();
    $order->order_id = $this->get_value($values, 'order_id');
    // Add hash key for a download link.
    $hash = hash('md5', $order->order_id . $values->commerce_order_created);

    $text = !empty($this->options['text']) ? $this->options['text'] : t('Download');
    return l($text, "order2pdf/{$order->order_id}/{$hash}");

My last step is to say Drupal about these files in commerce_order2pdf.info

For this step I will just add two rows to my .info file. 

files[] = includes/views/commerce_order2pdf.views.inc
files[] = includes/views/commerce_order2pdf_link_handler.inc

Now you can add views download field to your view. (If you make thses changes after you enabled your module then you can just clear caches and it will work).

Edit: Use the Inline entity form module that was created after this post was published.

This post will go over an example (yet fully functionally) module that shows how we can embed a commerce product form inside a node form, and have the node reference the commerce product - without horrible hacks.

The problem is obviously the fact that we don’t have commerce product ID nor a node ID, as none of those objects is saved. A second problem is how to actually embed the commerce product form inside the node form. Subform module solves both issues (with a little custom code help).

I won’t go over each line of code here, as the module is well documented, however I will explain the important steps.

In the node's form alter, we embed the commerce product, using Subform’s form element.

('inc', 'commerce_product', 'includes/commerce_product.forms');
$form['commerce_product_subform'] = array(
'#type' => 'subform',
'#subform_id' => 'commerce_product_ui_product_form',
'#subform_arguments' => array($commerce_product),
'#required' => TRUE,
'#weight' => 10,

In the code above we embed the form, pass it a $product object, and say it is required - meaning Subform should do validation on the embedded form.
Next step, is adding submit handlers in the right order

// Set the first submit handler to be "subform_submit_all", so the
// commerce product will be created, before handing the submitted node
// se we can associate the node to the commerce product.
// The last submit handler is the original 'node_form_submit', which
// will get all the values already populated, and save the node.
if (empty($node->nid)) {
array_unshift($form['actions']['submit']['#submit'], 'subform_submit_all', 'commerce_product_subform_commerce_product_submit');
else {
// The node already exists, so we assume there is already a reference
  // to the commerce product, so just add "subform_submit_all" submit
  // handler, to make sure the commerce product can be edited.
array_unshift($form['actions']['submit']['#submit'], 'subform_submit_all');

Noticed the emphasize on the “right order” above? That’s because we want Subform to first submit the commerce product form (thus the commerce product will be saved and have an ID), next we want our own submit handler to set the field reference from the node to the commerce product, and last we want the original node_form_submit() to save the node.

In the example module, you will notice that we also hide the commerce product title. The reason is that we can easily populate the title from the node's title (see commerce_product_subform_form_commerce_product_ui_validate()).

As bonus, the example module also has a CTools plugin, that allows you to add the subform to an node add/ edit page that was overriden by Page manager.
