woocommerce 添加来自元的自定义费用，并通过来自重力形式的元值乘以倍数

Question

好的，到目前为止，这是我的代码，我可以通过自定义字段在每个产品中设置自定义费用，购物车中的所有内容都正确显示。现在我需要能够将它乘以来自重力表单插件的下拉字段的值。我有 woocommerce 重力形式插件。

add_action( 'woocommerce_cart_calculate_fees','woocommerce_custom_surcharge');
function woocommerce_custom_surcharge() {
global $woocommerce;
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
    return;
//Loop through the cart to find out the extra costs
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
    //Get the product info
    $_product = $values['data'];


    //Get the custom field value
    $custom_fee = get_post_meta($_product->id, 'taxes_fees', true);


    //Adding together the extra costs
    $extra_custom_fee = $extra_custom_fee + $custom_fee;
}

//Lets check if we actually have a fee, then add it
if ($extra_custom_fee) {$woocommerce->cart->add_fee( 'Taxes & Fees', $extra_custom_fee, true, 'standard' )* $field["choices"][0]["value"];
}}

简单示例

$fee="20";
adult=2
child=2
$var1=adult+child=4
$fee*$var1="80"

好的，我从朋友那里得到了答案，我会 post 把它放在这里，以防有一天有人需要它。我的网站是一个 activity 网站，我有自定义字段，我在其中输入费用，我有带有 "inputname" 的重力表单字段，这是 css 和动态名称。我得到这些名称（来自重力的api）并得到价值，分解所有东西并取数字并将其乘以每个产品的费用。

add_action('woocommerce_cart_calculate_fees','woocommerce_custom_surcharge');
function woocommerce_custom_surcharge()
{
global $woocommerce;
if (is_admin() && !defined('DOING_AJAX')) return;

$extra_custom_fee = 0;

//Loop through the cart to find out the extra costs
foreach ($woocommerce->cart->get_cart() as $cart_item_key => $values) {

    //Get the product info
    $_product = $values['data'];

    // Find ID's for Adults and Kids charge in Gravity Form
    $form = GFAPI::get_form($values['_gravity_form_data']['id']);

    $total_adults = 0;
    $total_kids = 0;

    foreach ($form['fields'] as $field) {
        if ($field['inputName'] == 'adultsprice' &&
            !empty($values['_gravity_form_lead'][$field['id']])) {
            $parts = explode('|', $values['_gravity_form_lead'][$field['id']]);
            if (count($parts) == 2) {
                $total_adults = intval($parts[0]);
                $total_adult_charge = doubleval($parts[1]);
            }
        }
        else if ($field['inputName'] == 'kidsprice' &&
            !empty($values['_gravity_form_lead'][$field['id']])) {
            $parts = explode('|', $values['_gravity_form_lead'][$field['id']]);
            if (count($parts) == 2) {
                $total_kids = intval($parts[0]);
                $total_kids_charge = doubleval($parts[1]);
            }
        }
    }

    //Get the custom field value
    $custom_fee = intval(get_post_meta($_product->id, 'taxes_fees', true));

    //Adding together the extra costs
    $extra_custom_fee += $custom_fee * ($total_adults + $total_kids);

}

//Lets check if we actually have a fee, then add it
if ($extra_custom_fee > 0) {
    $woocommerce->cart->add_fee('Taxes & Fees', $extra_custom_fee, true, 'standard');
}
}
