Wordpress 如果选择“货到付款”，则隐藏帐单地址

在WooCommerce中，我希望在选择货到付款时能够隐藏帐单地址字段，因为不需要填写地址。但如果客户选择信用卡，则应显示账单地址

我真的不知道从哪里开始，所以我没有任何代码。

首先，账单地址是woo commerce的必填字段，因此，即使您将其隐藏，也不允许您结账。因此，首先需要使其成为“非必需的”，可以使用钩子来完成

然后可以运行查询

jQuery(function(){
    jQuery( 'body' )
    .on( 'updated_checkout', function() {
          usingGateway();

        jQuery('input[name="payment_method"]').change(function(){
            console.log("payment method changed");
              usingGateway();

        });
    });
});


function usingGateway(){
    console.log(jQuery("input[name='payment_method']:checked").val());
    if(jQuery('form[name="checkout"] input[name="payment_method"]:checked').val() == 'COD'){
        $('.woocommerce-billing-fields').hide();
        //Etc etc
    }
}

我能够对上面的代码进行一些扩展

// Make Billing Address not required
add_filter( 'woocommerce_default_address_fields' , 'filter_default_address_fields', 20, 1 );
function filter_default_address_fields( $address_fields ) {
    // Only on checkout page
    if( ! is_checkout() ) return $address_fields;

    // All field keys in this array
    $key_fields = array('country','company','address_1','address_2','city','state','postcode');

    // Loop through each address fields (billing and shipping)
    foreach( $key_fields as $key_field )
        $address_fields[$key_field]['required'] = false;

    return $address_fields;
}

如果是COD，则隐藏账单地址；如果是信用卡，则显示账单地址

jQuery(function(){
    jQuery( 'body' )
    .on( 'updated_checkout', function() {
          usingGateway();

        jQuery('input[name="payment_method"]').change(function(){
            console.log("payment method changed");
              usingGateway();

        });
    });
});


function usingGateway(){
    console.log(jQuery("input[name='payment_method']:checked").val());
    if(jQuery('form[name="checkout"] input[name="payment_method"]:checked').val() == 'cod'){
        jQuery('.woocommerce-billing-fields #billing_company_field, .woocommerce-billing-fields #billing_country_field, .woocommerce-billing-fields #billing_address_1_field, .woocommerce-billing-fields #billing_address_2_field, .woocommerce-billing-fields #billing_city_field, .woocommerce-billing-fields #billing_state_field, .woocommerce-billing-fields #billing_postcode_field, .woocommerce-shipping-fields').hide();
        //Etc etc
    } else {
                jQuery('.woocommerce-billing-fields #billing_company_field, .woocommerce-billing-fields #billing_country_field, .woocommerce-billing-fields #billing_address_1_field, .woocommerce-billing-fields #billing_address_2_field, .woocommerce-billing-fields #billing_city_field, .woocommerce-billing-fields #billing_state_field, .woocommerce-billing-fields #billing_postcode_field, .woocommerce-shipping-fields').show();
    }
}
