  1. Drupal commerce Dealing with any shopping scenario

  2. Introduction • Drupal Commerce adds the functionality online merchants need in a Drupal based site! Eg Cart, Checkout, Orders, Invoices, Shipping, Tax etc • Created by Ryan Szrama, the author of Ubercart • Like Drupal, acts as a framework which can be extended • Distributions for catering to specific scenarios • Built/supported by Commerce Guys • 23,000 + active sites • Growing Commerce specific contrib • Huge potential

  3. Why Drupal Commerce • Hands down beats most E-com solutions for anything CMS / Social etc • Huge D7 contrib space which can be used in Commerce, Eg Image Galleries, Flags, Ratings, newsletters, support forums, blogs etc • Powerful search with Search API, Facet API and Solr • Good theme system / responsive - Omega • Where it currently falls down • Not as mature as existing solutions / not as tried and tested • Actually still pretty complicated for a standalone simple store • We all know Drupal and have been building CMS sites, why not start using our skills to tackle E Commerce?

  4. Distributions • Commerce Kickstart • Best introduction for commerce • http://drupal.org/project/commerce_kickstart • http://demo.commerceguys.com/ • MartPlug • http://drupal.org/project/martplug • http://demo.martplug.com/ • Open Deals • http://drupal.org/project/opendeals • http://opendealsapp.com/demo/

  5. commerce dependencies • Views • Rules • Address field • Entity API • Why are these important? • Existing ecosystem - lots of modules are “entity-aware” • Use standard hooks/classes (egEntityFieldQuery & Metadata Wrappers) • Hmmmm tasty! Views & Rules…

  6. Commerce entities

  7. Commerce fields • Status – cannot edit, from product module • SKU – cannot edit, from product module • Address – from Address contrib module • Price • Product reference • Line item reference • Customer profile reference • Add Attributes as almost any field

  8. Entity metadata wrappers • Provided by Entity API • Much of Commerce expects you to use entity metadata wrappers • Used by Rules & Search API for their magic • Benefits: • Allows chaining • Prevents hardcoded nesting • Easier Looping • Getters and Setters • Some nice extra methods like access, validate etc Entity API takes an entity type and an entity object as parameters to create a new object which has many useful methods attached to aid in accessing and manipulating an entities properties and fields

  9. Entity metadata wrappers examples • How to get the wrapper and see what's available: • $wrapper = entity_metadata_wrapper('node', $node); • dpm($wrapper->getPropertyInfo()); • Helps get values without the nesting. Eg • $node->field_name[LANGUAGE_NONE][0][‘value’]; • Becomes: • $wrapper->field_name->value(); • Set the field with: • $wrapper->field_name->set(“new value”)

  10. Entity metadata wrappers examples • Chaining Entity data with Audoloading • $order_wrapper = entity_metadata_wrapper(‘commerce_order’, $order); • $address = $order_wrapper->commerce_customer_billing->commerce_customer_address->value() • Looping through a list: • $order_wrapper= entity_metadata_wrapper(’commerce_order', $order); • foreach($order_wrapper->commerce_line_item->value() as $item) { • //$item is a fully loaded line item entity. • //Get product fields $item->commerce_product->field_name->raw() • }

  11. EntityFieldQuery • Provided by Drupal 7 Core API • Query your entities and their field data without writing complex join queries or knowing the schemas. /** * Implements hook_commerce_product_can_delete(). */ function commerce_product_reference_commerce_product_can_delete($product) { // Use EntityFieldQuery to look for line items referencing this // product and do not allow the delete to occur if one exists. $query = new EntityFieldQuery(); $query ->entityCondition('entity_type', 'commerce_line_item', '=') ->entityCondition('bundle', commerce_product_line_item_types(), 'IN') ->fieldCondition('commerce_product', 'product_id', $product->product_id, '=') ->count(); return $query->execute() == 0; }

  12. Views & Rules • Views: • Baskets, Checkout etc all built using Rules so can be extended • Uses Views to make your Product listings / Catalogues • Build those custom order reports etc pretty quickly • Rules: • Adjust Prices using Rules for different roles, dates • Tax and Shipping rates use Rules so can be modified • Expire Products with Rules Scheduling • Remove Items from the Cart • Manage Experience with Custom Messages & Emails

  13. Commerce specific contrib

  14. Commerce scenario Demos • Store needs Customizable products: • Flower shop needs to allow customers to define a custom message and date of delivery. • How to: • The line item is fieldable with the contrib module commerce_custom_productand allows for use cases like business cards, event registrations or donations where customer input is required to be stored. • The field is stored on the line item so its unique to a product. • Demo: http://kickstart.localhost:8082/customproduct/custom-shoes#

  15. Commerce scenario Demos • Store needs custom node / validation in checkout • A shop requires customers agree to a terms of service before they can make a purchase • How to: • Using commerce_extra_panes allows any node to be added in to the checkout process and ordered. Once the node is added a checkout can be included via a hook form alter using validation to ensure the custom has agreed

  16. Commerce scenario recipes • Subscription (membership site) • Install & configure “role_expire” • Setup a “Member” role with default expiration • Install & configure content_access to restrict view access to Members • Setup a “Membership” product • On order completion use Rules to Apply the “Member” role to the customer and depending on product set expiration time • Alternatively • Try commerce_sp – a feature module or commerce_subscription

  17. Commerce scenario recipes • Virtual goods / Subscription • Sell Product keys: • commerce_product_key – allows attaching unique product keys to orders to unlock / activate software • Sell files: • commerce_file – allows commerce to sell file access • Sell Individual Nodes: • Similar approach to selling membership, however each product should have a node reference to the node which a customer is buying access to. Also use content_access Rules module so on completing as order , loop through the line items using a component, if a node reference is set grant access to the node for the customer

  18. Commerce scenario recipes • Gamification • Applicable for Forums, Support sites etc where users can earn points and the get discounts. Use commerce_userpoints to buy products with points or use them to discount purchases
