Paypal Express Flow

The PayPal Express Checkout Integration Guide is a great source of well-written information for anything relating to the Express checkout, including information regarding all of the API calls. Also, the PayPal Express Checkout flow diagram illustrates the process well:

The same information as contained in the diagram above is also in the table below:

Step / URL	PayPal API Call	Notes
https://www.domain.com/checkout/onepage/saveOrder		Saves order, 302’s to next step
https://www.domain.com/paypal/express/start	SetExpressCheckout	302’s with PayPal token to next step
https://www.paypal.com/webscr?cmd=_express-checkout&token=(token)
(paypal)
https://www.sandbox.paypal.com/uk/cgi-bin/merchantpaymentweb		HTML redirect to next step
https://www.domain.com/paypal/express/return?token=(token)	GetExpressCheckoutDetails	Details saved to payment, 302’s to next step
https://www.domain.com/paypal/express/review		Review, user submits to next step
https://www.domain.com/paypal/express/placeOrder	DoExpressCheckoutPayment	Places the order, 302’s to next step
https://www.domain.com/checkout/onepage/success		Confirmation is shown

API Calls

I enabled the debug mode in PayPal Express on Magento to illustrate the data that is moved between Magento and PayPal during a successful checkout.

SetExpressCheckout

The SetExpressCheckout API operation initiates an Express Checkout transaction.

GetExpressCheckoutDetails

TheGetExpressCheckoutDetailsAPI operation obtains information about an Express Checkout transaction.

DoExpressCheckoutPayment

TheDoExpressCheckoutPaymentAPI operation completes an Express Checkout transaction.

Important Classes

Class	Purpose
`Mage_Paypal_Controller_Express_Abstract`	Provides much of the base functionality for the two controllers
`Mage_Paypal_ExpressController`	Standard (US?) express controller
`Mage_PaypalUk_ExpressController`	UK express controller
`Mage_Paypal_Model_Express`	Express payment method
`Mage_Paypal_Model_Express_Checkout`	?
`Mage_Paypal_Model_Api_Nvp`	PayPal Name-Value Pair API Wrapper

Allowing Import Of Invisible Attributes

By setting a Product Attributeto be invisible via thevisible property, you stop the ability to import that attribute unless you alter the_forcedAttributesCodesproperty of the relevant product type. The class names are:

Mage_ImportExport_Model_Import_Entity_Product_Type_Simple
Mage_ImportExport_Model_Import_Entity_Product_Type_Grouped
Mage_ImportExport_Model_Import_Entity_Product_Type_Configurable

The best method is probably to subclass the relevant product import class, then overwrite the property. It would be far better to use the constructor to append to the property rather than just overwrite it to make future upgrades as smooth as possible, but Magento, in all their wisdom, have marked the constructor as final so you cannot do this, and we have no events to take advantage of.

Adding A CSS Class To The Body Tag

To add a class via layout XML:



<reference name="root">
    <action method="addBodyClass"><classname>whatever</classname></action>
</reference>

Or to add via code, from a controller or block



if ($root = $this->getLayout()->getBlock('root')) {
    $root->addBodyClass('whatever');
}

Disabling A Category

For some reason this does not work:

$category->setIsActive(false);

Get A Products Stock Quantity



$product->getStockItem()->getQty();

URL Route Parameters

Mage_Core_Model_Url::getUrl()

These are the core set of route parameters, you can be fairly sure that any call togetUrl() which accepts route parameters will come through this method, so any of these parameters should work.

Param	Type	Does
_store	string, int	Use a stores config, numeric or string code
_type	string	Using the relevant types URL, either link, direct_link, js. media or skin
_secure	bool	Use the secure URL if allowed
_forced_secure	bool	Force using the secure URL
_use_rewrite	bool	Resolves the link to a rewritten SEO URL
_nosid	bool	Prevents the SID query param from being added
_absolute	bool	No effect as URLs are always generated as absolute.
_current	bool	Uses the current module, controller, action and parameters
_direct	string	Appended to the base URL, apparently (really?)
_fragment	string	Sets the fragment (#whatever) component
_escape	bool	Uses & instead of & for querystring parameters
_query	string, array	Sets the query parameters
_store_to_url	bool	Adds ___store to the query parameters

Mage_Catalog_Model_Product_Url::getUrl()

These are extra parameters only noticed by the product URL method.

Param	Type	Does
_ignore_category	bool	Stops the category from appearing in the path. SeeGetting A Products URL for more info

Stop Controller Dispatch

In an action controllers preDispatch() method you can stop dispatch by calling the following:



$this->setFlag('', self::FLAG_NO_DISPATCH, true);

If you were listening via an observer, your code would look like this:



public function someObserver(Varien_Event_Observer $observer)
{
    $action = $observer->getEvent()->getControllerAction();
    $action->setFlag('', Mage_Core_Controller_Varien_Action::FLAG_NO_DISPATCH, true);
}

Getting The Last Order ID From The Session



Mage::getSingleton('checkout/session')->getLastOrderId();
