Ecommerce developers with Magento

For the last two days I’ve been working on a custom checkout page for one of our clients. Basicaly a page can be shown in Magento using simple Core_Template type. Basically all code is set inside the .phtml file so it can be shown on every possible page or block, meaning it’s object independent, no inheritance. Something you can call from with your layout files like

<block type=”core/template” name=”checkout_customcart” template=”checkout/customcart.phtml” />

To complete my work, I had two mayor requirements. One was to manage my way around programmable adding a simple products to cart, plus their quantity and other was to do checkout with items in cart. Checkout was to be made with predefined payment method as well as shipping method. After reviewing a lot of Magento’s code involved in checkout process and process of adding products to cart and so on I’ve put together what I see as the most short example one can use to do a checkout with such predefined conditions.

If you have such special requirements for your site below is the code that you can place on whatever file you wish and include it yout tempalte as block type core/template.

$checkout = Mage::getSingleton(’checkout/type_onepage’);
/*
* One page checkout consists of following steps
* (1) Customer login method aka Checkout method
* (2) Billing information (address)
* (3) Shipping information (address)
* (4) Shipping method
* (5) Payment information
* (6) Order review, in short: DO THE ORDER
*/

//STEP(1)
$checkout->saveCheckoutMethod(’guest’);

//STEP(2)
$checkout->saveBilling($billingAddress, false);

//STEP(3)
$checkout->saveShipping($shippingAddress, false);

//STEP(4)
$checkout->saveShippingMethod(’flatrate_flatrate’);

//STEP(5)
$checkout->savePayment(array(’method’=>’checkmo’));

//STEP(6)
/*
* $checkout->saveOrder() returns array holding empty object
* of type Mage_Checkout_Model_Type_Onepage
*/
$checkout->saveOrder();

And here is the example of how the $address variables are supose to look

[billing] => Array
(
[address_id] => 5
[firstname] => Branko
[lastname] => Ajzele
[company] => Surgeworks
[email] => ajzele@somemail.com
[street] => Array
(
[0] => Address part 1
[1] => Address part 2
)

[city] => Osijek
[region_id] =>
[region] =>
[postcode] => 31000
[country_id] => HR
[telephone] => 0038531000331
[fax] => 0038531000332
[customer_password] =>
[confirm_password] =>
[save_in_address_book] => 1
)

[shipping] => Array
(
[address_id] => 6
[firstname] => Ivan
[lastname] => Weiller
[company] => Surgeworks
[street] => Array
(
[0] => Address part 1
[1] => Address part 2
)

[city] => Osijek
[region_id] =>
[region] =>
[postcode] => 31000
[country_id] => HR
[telephone] => 0038531000333
[fax] => 0038531000334
[save_in_address_book] => 1
)

And you can wrapp the above checkout code into something like

if($this->getRequest()->getParam(’submitCustomCheckout’))
{
//Checkout code from above…
}

Where ubmitCustomCheckout is the name of the submit button or submit input field. To extract addresses you can use something like

$billingAddress = $this->getRequest()->getParam(’billing’);
$billingAddress['use_for_shipping'] = 0;
$shippingAddress = $this->getRequest()->getParam(’shipping’);

That’s it. Simple, predefined checkout by whitch order can be make on one click.
