在 Woocommerce 中使用 2 位小数表示折扣金额，小数点设置为 0 位

Question

我在

wc-settings&tab=general

下使用 0 位小数，这对于我的用例来说效果很好。但现在为特定付款方式添加折扣，目前设置为 10%。

对于 12 美元的商品，它会将折扣值四舍五入为 1 - 由于前面提到的 0 位小数设置，总计为 11，而不是 10.8。

我想出的最接近的是以下过滤器，但导致运费也从 23 美元升至 23.23 美元。知道如何仅将 2 位小数应用于折扣金额而不干扰其他地方吗？

// Change woo settings from 0 at the moment in backend to 2 decimals for wallet payment
add_filter( 'wc_get_price_decimals', 'custom_price_decimals_for_wallet_s0dgPHq2',10,1);
function custom_price_decimals_for_wallet_s0dgPHq2( $decimals ) {
    
    // Check if we are on the front-end and WooCommerce session is available
    if ( !is_admin() && WC()->session && isset(WC()->session->chosen_payment_method) ) {
        // Only change decimal places if the chosen payment method is wallet
        if ( WC()->session->chosen_payment_method === 'wallet' ) {                  
        
            // Set to 2 decimals for wallet payments
            $decimals = 2;
            return $decimals;
        }           
        // Return the default value for other cases
        return $decimals;
    }   
}

这也是我的折扣码

add_filter( 'woocommerce_cart_calculate_fees', 'discount_based_on_payment_method_e643e', 10, 1 );
function discount_based_on_payment_method_e643e( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if ( ! ( is_checkout() && ! is_wc_endpoint_url() ) )
        return;
    
    $targeted_payment_method = 'wallet'; // Here define the desired payment method

    global $abc_options;
    $wallet_pay_discount_amount = $abc_options['wallet_payment_discount_amount_value'];
    $wallet_pay_discount_amount_formated = $wallet_pay_discount_amount / 100; // results in 0.10 for 10% and so on
    
    if( WC()->session->get('chosen_payment_method') === $targeted_payment_method ) {
        $cart_subtotal = WC()->cart->get_subtotal();
        $discount = $cart_subtotal * $wallet_pay_discount_amount_formated;

        $fee_description = '~ ' . $wallet_pay_discount_amount . '% ' . __('Discount Wallet Payment', 'nm-ffk');

        
        $cart->add_fee($fee_description, -$discount);
    }
}   

Answer 1

要仅更改 WooCommerce 结帐页面中显示的费用金额小数位，请使用以下代码替换：

add_filter( 'woocommerce_cart_totals_fee_html', 'filter_woo_cart_totals_fee_html', 10, 2 );
function filter_woo_cart_totals_fee_html( $fee_html, $fee ){
    $args = array('decimals' => 2 );
    return WC()->cart->display_prices_including_tax() ? wc_price( $fee->total + $fee->tax, $args ) : wc_price( $fee->total, $args );
}

add_filter( 'woocommerce_cart_calculate_fees', 'discount_based_on_payment_method_e643e', 10, 1 );
function discount_based_on_payment_method_e643e( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if ( ! ( is_checkout() && ! is_wc_endpoint_url() ) )
        return;
    
    $payment_id = 'wallet'; // The targeted payment method ID
    
    if( WC()->session->get('chosen_payment_method') === $payment_id ) {
        global $abc_options;

        $discount_rate   = $abc_options['wallet_payment_discount_amount_value'];
        $discount_amount = WC()->cart->get_subtotal() * $discount_rate / 100;
        $fee_description = '~ ' . $discount_rate . '% ' . __('Discount Wallet Payment', 'nm-ffk');

        $cart->add_fee($fee_description, -$discount_amount);
    }
}
