Drupal commerce 己經成為 Drupal 電子商務應用的主流了，ubercart 落伍了
Ubercart 是一個源自 Drupal5.x 世代的方案
而為了使用 Drupal7 方便的 entities，和令電子商務方案使用一個「弱品牌化」的名字，Drupal commerce 誕生了
但因為 Drupal commerce 龐大的代碼量，為了方便分散工作，代碼都打散到不同的模組，各自有他們的維護者
再加上為數不少的 dependencies 令上手的難度過大
所以 Drupal commerce kickstart 便將一個完整的電子商務網站包裝起來
只需要下載安裝，匯入範例便可以立即使用了
這次的開發和前一次類似，從代碼建立將貨物放到訂單：
<?php
$cp = commerce_product_new($type);
$cp->is_new = TRUE;
$cp->revision_id = NULL;
$cp->uid = $user->uid;
$cp->status = 1;
$cp->language = LANGUAGE_NONE;
$cp->created = $cp->changed = time();
$cp->sku = 'shirt_od' . $extras['title'] . drupal_hash_base64(microtime());
$cp->title = $cp->sku;
?>使用
<?php
field_attach_submit()
?><?php
$price = array(LANGUAGE_NONE => array(0 => array(
'amount' => $price * 100,
'currency_code' => commerce_default_currency(),
)));
$form_state['values']['commerce_price'] = $price;
// custom fields
$form_state['values']['field_quantity'] = array(LANGUAGE_NONE => array(0 => array('value' => $quantity)));
$unit_price = array(LANGUAGE_NONE => array(0 => array(
'amount' => $unit_price * 100,
'currency_code' => commerce_default_currency(),
)));
$form_state['values']['field_unit_price'] = $unit_price;
field_attach_submit('commerce_product', $cp, $form, $form_state);
commerce_product_save($cp);
?>購物車：
<?php
$order = commerce_order_new($uid, 'cart');
commerce_order_save($order);
$line_item = commerce_product_line_item_new($cp, 1, $order->order_id);
// Save the line item to get its ID.
commerce_line_item_save($line_item);
// Add the line item to the order using fago's rockin' wrapper.
$order_wrapper = entity_metadata_wrapper('commerce_order', $order);
$order_wrapper->commerce_line_items[] = $line_item;
// Save the order again to update its line item reference field.
commerce_order_save($order);
