You can change the calculated price by using WordPress filters in your theme or custom plugin.

For new integrations, use the yps_calcsheet_* filters shown below. Legacy awspc_* filters are still supported for backward compatibility, but they should not be used in new code.

You can place these examples in your theme functions.php file or in a custom plugin.

Change the final calculated price

/*
* $price                     The final formatted-or-unformatted price value currently being returned.
* $params['errors']          Validation errors.
* $params['priceRaw']        Raw numeric price before formatting.
* $params['product']         Product data.
* $params['calculator']      Calculator object.
* $params['data']            Raw input values.
* $params['userData']        Transformed values used by the calculation engine.
* $params['outputResults']   Output field results.
* $params['formatPrice']     Whether the final price should be formatted.
*/
function custom_yps_calcsheet_filter_calculate_price($price, $params){
    return $price * 5;
}
add_filter('yps_calcsheet_filter_calculate_price', 'custom_yps_calcsheet_filter_calculate_price', 10, 2);

add_filter is a WordPress core function. See the official documentation for more details.

Change only the AJAX calculation response

/*
* $response['errorsCount']       Number of validation errors.
* $response['errors']            Validation errors.
* $response['price']             Formatted price returned to the frontend.
* $response['priceRaw']          Raw numeric price.
* $response['outputFields']      Output field values.
* $response['conditionalLogic']  Visibility map for calculator fields.
*
* $params['productId']           Product ID.
* $params['calculator']          Calculator object.
* $params['fields']              Calculator fields used at runtime.
* $params['postData']            Raw values sent by the frontend.
* $params['conditionalLogic']    Visibility map for calculator fields.
* $params['outputResults']       Output field results before serialization.
* $params['errors']              Validation errors.
* $params['price']               Formatted price returned to the frontend.
* $params['priceRaw']            Raw numeric price.
* $params['page']                Runtime context such as product or cart.
*/
function custom_yps_calcsheet_filter_calculate_price_ajax_response($response, $params){
    return $response;
}
add_filter('yps_calcsheet_filter_calculate_price_ajax_response', 'custom_yps_calcsheet_filter_calculate_price_ajax_response', 10, 2);

Change the calculator price in cart

If you want to adjust the product price in cart, for example to add a surcharge, discount, or custom tax logic, use the cart price filter below.

/*
* $productPrice            The current calculated product price in cart.
* $fieldsData              The current calculator field values.
* $outputFields            The current output field values.
*/
function custom_yps_calcsheet_filter_calculate_price_in_cart($productPrice, $fieldsData, $outputFields){
    return $productPrice + 100;
}
add_filter('yps_calcsheet_filter_calculate_price_in_cart', 'custom_yps_calcsheet_filter_calculate_price_in_cart', 10, 3);
