Merhaba Wocommercede kapıda kredi kartı seçeneğine sepet fiyatının yüzde 3'ünü eklemek istiyorum şöyle bir kod var

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

if ( 'wookkkotr' === WC()->session->get('chosen_payment_method') ) {
$fee = 5;
$cart->add_fee( 'Kapıda Kredi Kartı ile Ödeme Ekstra Ücret', $fee, true );
}
}
add_action( 'wp_footer', 'custom_checkout_jqscript' );
function custom_checkout_jqscript() {
if ( is_checkout() && ! is_wc_endpoint_url() ) :
?>
<script type="text/javascript">
jQuery( function($){
$('form.checkout').on('change', 'input[name="payment_method"]', function(){
$(document.body).trigger('update_checkout');
});
});
</script>
<?php
endif;
}

burdaki $fee değerini $cart+($cart*0.3) yapıyorum ama olmuyor yanlış mı ilerliyorum acaba


Çözüm

add_action( 'woocommerce_cart_calculate_fees', 'custom_percentage_fee', 20, 1 );
function custom_percentage_fee ( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if ( ! ( is_checkout() && ! is_wc_endpoint_url() ) )
        return; // Only checkout page

    $payment_method = WC()->session->get( 'chosen_payment_method' );

    if ( 'wookkkotr' == $payment_method ) {
        $surcharge = $cart->subtotal * 0.03;
        $cart->add_fee( 'Percentage Cost', $surcharge, true );
    }
}

// jQuery - Update checkout on methode payment change  
add_action( 'wp_footer', 'custom_checkout_jqscript' );
function custom_checkout_jqscript() {
    if ( ! ( is_checkout() && ! is_wc_endpoint_url() ) )
        return; // Only checkout page
    ?>
    <script type="text/javascript">
    jQuery( function($){
        $('form.checkout').on('change', 'input[name="payment_method"]', function(){
            $(document.body).trigger('update_checkout');
        });
    });
    </script>
    <?php
}
