What is it?

A brief review (March 2008 – November 2012)

1.0 - 1.3

If it works, it’s okay (go on, hack the core)

CE 1.4 - 1.5 / EE 1.6 - 1.10

Put everything into modules (rewrite conflicts, messy themes)

CE 1.6 / EE 1.11

(Guess) best practices (upgradability, compatibility, accountability)

CE 1.7 / EE 1.12

Create quality code (confirmed best practices, functional & integration testing)

Adminhtml Field Renderers

Renderers put elements in context

Renderer

Adminhtml Widget Forms

System Configuration Forms

Adminhtml Widget Form Fields

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(); }

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(); }

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

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(); }

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(); } }

System Configuration Fields

System configuration

• Default field renderer: adminhtml/system_config_form_field

• Set in: adminhtml/system_config_form

Custom system configuration field renderer

A Custom Renderer magento_live/adminhtml_system_config_custom 10 1 1 1

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(); } }

In the template access element properties

• $this->getElement()->getLabelHtml()

• $this->getElement()->getElementHtml()

• $this->getElement()->getName()

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

Payment Flow

Some basic prerequisites

$methodInstance->initialize()

Order State: NEW

Order Status: getConfigData('order_status')

or, if not set, PENDING


payment method instance ::getConfigData('payment_action')

not set?

possible return values besides null?

• 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


• 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; }



Customer Magento


'order' is not different from the 'authorize'

except for the method names

Customer Magento


sales/order_payment ::capture(null)

sales/order ::prepareInvoice()

sales/order_invoice ::capture()

sales/order_payment ::capture($invoice)

payment method instance ::capture($infoInstance, $amount)

How about payments via redirect?


Magento Host


Magento Host

Redirects are not supported by checkout/type_multishipping

✗


Magento Host

Redirects are supported by checkout/type_onepage


Magento Host

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


Magento Host

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

And what about the payment related data?

Payment data handling

checkout/type_onepage ::savePayment()

sales/quote_payment ::importData($data)

payment method instance ::assignData($data)

sales/quote_payment ::addData($data)

sales/(quote|order)_payment ::setAdditionalInformation($key, $value)

Persist data

Payment flow summary • Configure , and 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
