我是用wc_create_order 这是完整的代码

`如果（isset（$\\u POST[\'submitted\']））{

$address = array(
    \'first_name\' => $_POST[\'fullname\'],
    \'email\'      => $_POST[\'email\'],
    \'phone\'      => $_POST[\'phone\'],
    \'address_1\'  => $_POST[\'address\'], 
    \'city\'       => $_POST[\'city\'],
);

$order = wc_create_order();
$order->add_product( get_product( get_the_id() ), $_POST[\'quantity\'] );
$order->set_address( $address, \'billing\' );
$order->set_address( $address, \'shipping\' );
$order->set_payment_method( \'cod\' );
$order->calculate_totals();
