英文:
Multiplication of function result breaks calculation (WordPress)
问题
这段代码中存在问题，当货币为THB（泰铢）时，代码将转换后的总额乘以2，但这会导致错误的结果。您可以尝试以下更改：
将这行代码：
$converted_total_gptlove *= 2;
改为：
if ( $currency_to === 'thb' ) {
$converted_total_gptlove *= 2;
}
这将确保只有当货币是THB时才执行乘法操作，从而修复了问题。
英文:
I have some code that uses a plugin that does currency conversion. Depending on the payment method, the code creates a converted order total and later saves it as a custom field. I would like to perform a multiplication if the conversion is to a specific currency, but it breaks the conversion functionality and returns a "4" instead of a converted total. Any idea what is wrong?
This code works and converts the order total correctly:
// Add custom order meta data on checkout
add_action( 'woocommerce_checkout_create_order', 'add_custom_order_meta', 10, 2 );
function add_custom_order_meta( $order, $data ) {
// Get the payment method for the order
$payment_method = $order->get_payment_method();
// Only add custom meta data for certain payment methods
if ( in_array( $payment_method, array( 'bacs', 'cheque' ) ) ) {
// Get the order total
$order_total = $order->get_total();
// Set the currency to convert to based on payment method
$currency_to = ( $payment_method === 'bacs' ) ? 'hkd' : 'thb';
// Convert the order total to the selected currency
$converted_total_gptlove = get_conversion( 'number=' . $order_total . '&from=usd&to=' . $currency_to . '&dp=2' );
// Set the currency symbol and code based on payment method
$currency_symbol = ( $payment_method === 'bacs' ) ? '$' : '฿';
$currency_code = ( $payment_method === 'bacs' ) ? 'HKD' : 'THB';
// Update the order meta data with the converted total and currency info
$order->update_meta_data( 'converted_total_gptlove', $currency_symbol . $converted_total_gptlove . ' ' . $currency_code );
}
}
This code adds the multiplication, and returns a 4 instead of the converted total multiplied by 2:
// Add custom order meta data on checkout
add_action( 'woocommerce_checkout_create_order', 'add_custom_order_meta', 10, 2 );
function add_custom_order_meta( $order, $data ) {
// Get the payment method for the order
$payment_method = $order->get_payment_method();
// Only add custom meta data for certain payment methods
if ( in_array( $payment_method, array( 'bacs', 'cheque' ) ) ) {
// Get the order total
$order_total = $order->get_total();
// Set the currency to convert to based on payment method
$currency_to = ( $payment_method === 'bacs' ) ? 'hkd' : 'thb';
// Convert the order total to the selected currency
$converted_total_gptlove = get_conversion( 'number=' . $order_total . '&from=usd&to=' . $currency_to . '&dp=2' );
// Multiply the converted total by 2 if currency is THB
if ( $currency_to === 'thb' ) {
$converted_total_gptlove *= 2;
}
// Set the currency symbol and code based on payment method
$currency_symbol = ( $payment_method === 'bacs' ) ? '$' : '฿';
$currency_code = ( $payment_method === 'bacs' ) ? 'HKD' : 'THB';
// Update the order meta data with the converted total and currency info
$order->update_meta_data( 'converted_total_gptlove', $currency_symbol . $converted_total_gptlove . ' ' . $currency_code );
}
}
Could someone help pointing me in the right direction?

问题已解决，通过在转换函数之前对订单总额进行计算。
// 如果货币是THB，则将订单总额乘以2
$converted_order_total = $order_total;
if ($currency_to === 'thb') {
$converted_order_total *= 1.027;
}
英文:
The problem has been solved, by performing the calculation on the order total, before converting it with the function.
// Multiply the order total by 2 if currency to is THB
$converted_order_total = $order_total;
if ($currency_to === 'thb') {
$converted_order_total *= 1.027;
}
