在表单提交时以编程方式创建订单 OVERIDE PRODUCT PRICE

Question

我有一个代码，我想在提交表单时以编程方式在 WooCommerce 中创建订单。我希望我的代码确定产品价格 - 所以覆盖产品的默认价格。这可能吗？不知道我的代码哪里出错了：// set some variables$user_id =rgar( $entry, '97' );$product_id = rgar( $entry, '71' );$quantity = rgar( $entry, '73' ); $price = rgar( $entry, '90' );$note = rgar( $entry, '53' );$product = wc_get_product($product_id);            $address = array( 'first_name' => rgar( $entry, '98' ), 'last_name' => rgar( $entry, '99' ), 'company' => rgar( $entry, '' ), 'email' => rgar( $entry, '83' ), 'phone' => rgar( $entry, '84' ), 'address_1' => rgar( $entry, '88.1' ), 'address_2' => rgar( $entry, '88.2' ), 'city' => rgar( $entry, '88.3' ), 'state' => rgar( $entry, '88.4' ), 'postcode' => rgar( $entry, '88.5' ), 'country' => rgar( $entry, '88.6' ), );// Create the order object             $order = wc_create_order();$order->set_customer_id( $user_id );$order->add_product( wc_get_product($product_id), $quantity, $prices);foreach ($order->get_items() as $item_key => $item ) {    $item->add_meta_data( 'Label', $note, true );}$order->set_address( $address, 'billing' );$order->calculate_totals();$order->update_status( 'pending payment', 'pending', TRUE); $order->add_order_note( $note );                                            $coupon_code = rgar( $entry, '105' ); $order->apply_coupon($coupon_code);                                                   break;    }}“90”是我的表单的字段 ID，其中包含我想在产品订单中使用的价格。

用途：WC_Product::set_price()– 设置产品的有效价格。

下一行

$order->add_product( wc_get_product($product_id), $quantity, $prices);

将是

$order->add_product( $product, $quantity );

因为你已经用过wc_get_product

$product = wc_get_product($product_id);

---

然后你得到

// set some variables

$user_id =rgar( $entry, '97' );

$product_id = rgar( $entry, '71' );

$quantity = rgar( $entry, '73' ); 

$price = rgar( $entry, '90' );

$note = rgar( $entry, '53' );

$product = wc_get_product($product_id);

// Set price

$product->set_price( $price );

$address = array(

    'first_name' => rgar( $entry, '98' ),

    'last_name' => rgar( $entry, '99' ), 

    'company' => rgar( $entry, '' ),

    'email' => rgar( $entry, '83' ), 

    'phone' => rgar( $entry, '84' ), 

    'address_1' => rgar( $entry, '88.1' ), 

    'address_2' => rgar( $entry, '88.2' ), 

    'city' => rgar( $entry, '88.3' ), 

    'state' => rgar( $entry, '88.4' ), 

    'postcode' => rgar( $entry, '88.5' ), 

    'country' => rgar( $entry, '88.6' ),

);

// Create the order object 

$order = wc_create_order();

$order->set_customer_id( $user_id );

// add product to order

$order->add_product( $product, $quantity );

foreach ($order->get_items() as $item_key => $item ) {

    $item->add_meta_data( 'Label', $note, true );

}

$order->set_address( $address, 'billing' );

$order->calculate_totals();

$order->update_status( 'pending payment', 'pending', TRUE); 

$order->add_order_note( $note );

$coupon_code = rgar( $entry, '105' );

$order->apply_coupon($coupon_code);
