29 Adminhtml Field Renderers

30 Renderers put elements in context Renderer

31 Adminhtml Widget Forms

32 System Configuration Forms

33 Adminhtml Widget Form Fields

34 Adding a field to an adminhtml form protected function _prepareform() { $form = new Varien_Data_Form(); $this->setform($form); } $fieldset = $form->addfieldset('fieldset1', array( 'legend' => 'Example Fieldset' )); $fieldset->addfield('field1', 'select', array( 'name' => 'example2', 'label' => 'A Select Field', 'options' => array('', 'A', 'B', 'C') )); return parent::_prepareform();

35 Defaults are set in adminhtml/widget_form protected function _preparelayout() { Varien_Data_Form::setElementRenderer( $this->getlayout()->createblock('adminhtml/widget_form_renderer_element') ); Varien_Data_Form::setFieldsetRenderer( $this->getlayout()->createblock('adminhtml/widget_form_renderer_fieldset') ); Varien_Data_Form::setFieldsetElementRenderer( $this->getlayout()->createblock('adminhtml/widget_form_renderer_fieldset_element') ); } return parent::_preparelayout();

36 protected function _prepareform() { $form = new Varien_Data_Form(); $this->setform($form); $field1 = $form->addfield('example1', 'text', array( 'name' => 'example1', 'label' => 'Field w/o Fieldset', )); $fieldset = $form->addfieldset('fieldset1', array( 'legend' => 'Example Fieldset' )); $field2 = $fieldset->addfield('example2', 'text', array( 'name' => 'example2', 'label' => 'Field with Fieldset' )); adminhtml/widget_form_renderer_element adminhtml/widget_form_renderer_fieldset adminhtml/widget_form_renderer_fieldset_element

37 Setting a custom renderer protected function _prepareform() { $form = new Varien_Data_Form(); $this->setform($form); } $fieldset = $form->addfieldset('fieldset1', array( 'legend' => 'Example Fieldset' )); $field = $fieldset->addfield('field1', 'select', array( 'name' => 'example2', 'label' => 'A Select Field', 'options' => array('', 'A', 'B', 'C'), 'renderer' => magento_live/adminhtml_form_example_field_renderer' )); return parent::_prepareform();

38 Renderer interface class Magento_Live_Block_Adminhtml_Form_Example_Field_Renderer extends Mage_Adminhtml_Block_Template implements Varien_Data_Form_Element_Renderer_Interface { protected function _construct() { $this->settemplate( magento/live/form/field/renderer/example.phtml'); } } public function render(varien_data_form_element_abstract $element) { $this->setelement($element); return $this->tohtml(); }

39 System Configuration Fields

40 System configuration Default field renderer: adminhtml/system_config_form_field Set in: adminhtml/system_config_form

41 Custom system configuration field renderer <!-- system.xml --> <fields> <renderer_example> <label>a Custom Renderer</label> <!-- Specify the renderer (a block class): --> <frontend_model>magento_live/adminhtml_system_config_custom</frontend_model> <sort_order>10</sort_order> <show_in_default>1</show_in_default> <show_in_website>1</show_in_website> <show_in_store>1</show_in_store> </renderer_example> </fields> <! >

42 Custom system configuration field renderer class Magento_Live_Block_Adminhtml_System_Config_Custom extends Mage_Adminhtml_Block_System_Config_Form_Field { public function render(varien_data_form_element_abstract $element) { $element->setscope(false); // example customization return parent::render($element); } } protected function _getelementhtml(varien_data_form_element_abstract $element) { return $this->getlayout()->createblock('core/template', $element->getid(). '_tmp') ->settemplate( magento/live/system/config/custom.phtml') ->setelement($element)->tohtml(); }

43 In the template access element properties $this->getelement()->getlabelhtml() $this->getelement()->getelementhtml() $this->getelement()->getname()

44 ...that was the warm-up, on to part two...

45 Payment Flow

46 Some basic prerequisites

47 Onepage checkout Multiaddress checkout

48 Payment Method Process payment transactions identified by unique code model specified in global/payment/$code/model extend Mage_Payment_Model_Method_Abstract Payment Information Store Transaction Data sales/quote_payment sales/order_payment

49 Payment Method getmethodinstance() getinfoinstance() Payment Info

50 Payment Actions Authorize Reserve funds on card, capture or release later Capture Void Capture authorized the funds using token or id from authorize. Usually called when shipping items. Implementation specific. For example, release authorized funds, or void the whole payment. Creditmemo Synonym for refund. Only applicable to captured payments.

51 Order state & order status State A Status A1 Status A2 State B Status B1 Status C1 State C Status C2 Status C3

52 Order states Create Order STATE_NEW or STATE_PENDING_PAYMENT Invoiced Shipped STATE_PROCESSING or STATE_PENDING_REVIEW Invoiced && Shipped STATE_COMPLETE Refunded STATE_CLOSED

53 Communication with external payment providers Customer Customer Customer Magento Host Magento Host Payment Provider Payment Provider Magento Host

54 Prerequisites? Check

55 Here is the flow...

56 Onepage checkout/type_onepage ::saveorder() sales/service_quote ::submitall() ::submitorder() Multishipping checkout/type_multishipping ::createorders() sales/order ::place() ::_placepayment() sales/order_payment ::place() payment flow control logic Customer Magento Host Customer Magento Host Payment Provider

57 sales/order_payment ::place() if isinitializeneeded() == true protected $_isinitializeneeded $methodinstance->initialize( $methodinstance->getconfigdata('payment_action'), $stateobject // Varien_Object Instance ); $methodinstance->initialize() Order State: $stateobject->getstate() Order Status: $stateobject->getstatus() Customer Magento Host Payment Provider

58 sales/order_payment ::place() if isinitializeneeded() == false protected $_isinitializeneeded public function getconfigdata($field, $storeid = null) { $path = 'payment/'.$this->getcode().'/'.$field; return Mage::getStoreConfig($path, $storeid); } payment method instance ::getconfigdata('payment_action') not set? Order State: NEW Order Status: getconfigdata('order_status') or, if not set, PENDING Customer Magento Host

59 sales/order_payment ::place() if isinitializeneeded() == false protected $_isinitializeneeded payment method instance ::getconfigdata('payment_action') order Mage_Payment_Model_Method_Abstract::ACTION_ORDER authorize Mage_Payment_Model_Method_Abstract::ACTION_AUTHORIZE authorize_capture Mage_Payment_Model_Method_Abstract::ACTION_AUTHORIZE_CAPTURE possible return values besides null? Customer Magento Host Payment Provider

60 sales/order_payment ::place() payment method instance ::getconfigdata('payment_action') order $infoinstance->_order() authorize $infoinstance->_authorize() authorize_capture $infoinstance->capture() Customer Magento Host Payment Provider

61 getconfigdata('payment_action') == 'order' isinitializeneeded() == false sales/order_payment ::_order($order->getbasetotaldue()) payment method instance ::order($infoinstance, $amount) Payment hook method implement as needed public function order(varien_object $payment, $amount) { return $this; } Order State: PROCESSING or PAYMENT_REVIEW Order Status: $methodinstance->getconfigdata('order_status') Customer Magento Host Payment Provider

62 getconfigdata('payment_action') == 'authorize' isinitializeneeded() == false sales/order_payment ::_authorize($order->getbasetotaldue()) payment method instance ::authorize($infoinstance, $amount) Payment hook method implement as needed public function authorize(varien_object $payment, $amount) { return $this; } Order State: PROCESSING or PAYMENT_REVIEW Order Status: $methodinstance->getconfigdata('order_status') Customer Magento Host Payment Provider

63 'order' is not different from the 'authorize' except for the method names Customer Magento Host Payment Provider

64 Invoice creation getconfigdata('payment_action') == 'authorize_capture' isinitializeneeded() == false sales/order_payment ::capture(null) payment method instance ::capture($infoinstance, $amount) sales/order ::prepareinvoice() sales/order_invoice ::capture() sales/order_payment ::capture($invoice) sales/order_invoice ::pay() Order State: PROCESSING or PAYMENT_REVIEW Order Status: $methodinstance->getconfigdata('order_status') Customer Magento Host Payment Provider

65 How about payments via redirect? Customer Payment Provider Magento Host

66 Redirects are not supported by checkout/type_multishipping Customer Payment Provider Magento Host

67 Redirects are supported by checkout/type_onepage Customer Payment Provider Magento Host

68 Option one: Redirect after the customer selects the payment method. Mage_Checkout_OnepageController ::savepaymentaction() sales/quote_payment ::getcheckoutredirecturl() payment method instance ::getcheckoutredirecturl() No order is created before the redirect Create order after the customer is returned Customer Payment Provider Magento Host

69 Option one: Redirect after the the review order step. Mage_Checkout_OnepageController ::savepaymentaction() sales/quote_payment ::getcheckoutredirecturl() payment method instance ::getcheckoutredirecturl() Order was created before the redirect sales/order::place() was called() Update order after customer is returned Customer Payment Provider Magento Host

70 And what about the payment related data?

71 Payment data handling checkout/type_onepage ::savepayment() sales/quote_payment ::importdata($data) payment method instance ::assigndata($data) Persist data sales/quote_payment ::adddata($data) sales/(quote order)_payment ::setadditionalinformation($key, $value)

72 Payment flow summary Configure <model>, <active> and <payment_action> config nodes Create model, implement payment hook methods as needed initialize() authorize() capture() getcheckoutredirecturl() getorderplaceredirecturl() assigndata() For redirect payments implement controller and view layer logic
