提交表单后以编程方式创建订单覆盖产品价格 - WooCommerce

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。

我希望我的代码能够确定产品价格 - 因此覆盖产品的默认价格。

这可能吗？

不确定我的代码哪里出了问题：

// 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。

Answer 1

使用：

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);

将会是

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

因为你已经用过

wc_get_product

$product = wc_get_product($product_id);

然后你就得到了

// 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);

// 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);
