如果希望通過編程創建訂單，需要用到的代碼如下：
|
|
<?php
function generate_order() {
global $woocommerce;
// 用於存儲訂單中的用户信息
$address = array(
‘first_name’ => ‘111Joe’,
‘last_name’ => ‘Conlin’,
‘company’ => ‘Speed Society’,
’email’ => ‘joe@testing.com’,
‘phone’ => ‘760-555-1212’,
‘address_1’ => ‘123 Main st.’,
‘address_2’ => ‘104’,
‘city’ => ‘San Diego’,
‘state’ => ‘Ca’,
‘postcode’ => ‘92121’,
‘country’ => ‘US’
);
$order = wc_create_order();
$order->add_product( get_product(‘10235’), 1 ); // ‘10235’ 是產品 id，1 是產品數量
$order->set_address($address, ‘billing’); // 設置訂單地址
$order->calculate_totals();
update_post_meta( $order->id, ‘_payment_method’, ‘codetutor-alipay-for-wc’ ); // ‘codetutor-alipay-for-wc’ 是 payment_method
update_post_meta( $order->id, ‘_payment_method_title’, ‘ 支付寶’ ); // ‘ 支付寶’ 是 payment_method_title
// Store Order ID in session so it can be re-used after payment failure
WC()->session->order_awaiting_payment = $order->id;
// Process Payment
$available_gateways = WC()->payment_gateways->get_available_payment_gateways();
$result = $available_gateways[ ‘codetutor-alipay-for-wc’ ]->process_payment( $order->id );
// Redirect to success/confirmation/payment page
if ( $result[‘result’] == ‘success’ ) {
$result = apply_filters( ‘woocommerce_payment_successful_result’, $result, $order->id );
wp_redirect( $result[‘redirect’] );
exit;
}
}
generate_order();
?>

運行上面的代碼，會創建一個新的訂單，並且重定向到支付寶網關（這個支付寶網關是通過插件 Codetutor Alipay for WooCommerce 實現的）。在支付完成之後會跳轉到 thank you 頁面。
然後在 WP 後台的 WooCommerce-> 訂單中進行查看，可以看到這個新創建的訂單。
