在 WooCommerce 结账时选中 "Ship to a different address?" 时,为特定用户角色添加费用

Add a fee for specific user roles when "Ship to a different address?" has been checked on WooCommerce checkout

我有一个具有不同用户角色的批发站点,并且希望员工也可以从这里开始在线订购。

如果用户角色 'team' 和 'team2' select 送货到不同的地址,我只想增加 5 美元的费用(如果送货到他们的账单地址,他们可以免费送货) .

如果select运送到不同的地址,其他用户角色不应看到费用。

这是我找到的最接近实现此目的的解决方案,但需要帮助配置此代码以仅应用于这两个用户角色,而不应用于其他任何角色。

// send as gift for Team & Team2 role add  fee
add_filter( 'woocommerce_form_field' , 'remove_order_comments_optional_fields_label', 10, 4 );
function remove_order_comments_optional_fields_label( $field, $key, $args, $value ) {
    // Only on checkout page for Order notes field
    if( 'ship_to_different_address' === $key && is_checkout() ) {
        $optional = '&nbsp;<span class="optional">(' . esc_html__( 'optional', 'woocommerce' ) . ')</span>';
        $field = str_replace( $optional, '', $field );
    }
    return $field;
}

// Ajax / jQuery script
add_action( 'wp_footer', 'ship_to_different_address_script' );
function ship_to_different_address_script() {
    // On checkoutpage
    if( ( is_checkout() && ! is_wc_endpoint_url() ) ) :
        ?>
        <script type="text/javascript">
            jQuery( function($){
                if (typeof woocommerce_params === 'undefined')
                    return false;

                console.log('defined');

                $('input[name=ship_to_different_address]').click( function(){
                    var fee = $(this).prop('checked') === true ? '1' : '';

                    $.ajax({
                        type: 'POST',
                        url: woocommerce_params.ajax_url,
                        data: {
                            'action': 'ship_to_different_address',
                            'ship_to_different_address': fee,
                        },
                        success: function (result) {
                            $('body').trigger('update_checkout');
                            console.log(result);
                        },
                    });
                });
            });
        </script>
    <?php
    endif;
}

// Get the ajax request and set value to WC session
add_action( 'wp_ajax_ship_to_different_address', 'get_ajax_ship_to_different_address' );
add_action( 'wp_ajax_nopriv_ship_to_different_address', 'get_ajax_ship_to_different_address' );
function get_ajax_ship_to_different_address() {
    if ( isset($_POST['ship_to_different_address']) ) {
        WC()->session->set('ship_to_different_address', ($_POST['ship_to_different_address'] ? '1' : '0') );
        echo WC()->session->get('ship_to_different_address');
    }
    die();
}

// Add / Remove a custom fee
add_action( 'woocommerce_cart_calculate_fees', 'add_remove_ship_to_different_address', 10, 1 );
function add_remove_ship_to_different_address( $cart )
{
    // Only on checkout
    if ((is_admin() && !defined('DOING_AJAX')) || is_cart())
        return;

    $fee_amount = 5.00;

    if (WC()->session->get('ship_to_different_address'))
        $cart->add_fee(__('Shipping fee', 'woocommerce'), $fee_amount);
}

您的代码包含一些错误、遗漏部分和不必要的步骤。

此答案显示(没有任何用户限制)如何在“运送到不同地址?”时添加费用?已检查:

// The jQuery Ajax request
function action_wp_footer() {
    // Only checkout page
    if ( is_checkout() && ! is_wc_endpoint_url() ) :

    // Remove "ship_different" custom WC session on load
    if ( WC()->session->get( 'ship_different' ) ) {
        WC()->session->__unset( 'ship_different' );
    }
    
    // jQuery Ajax code below

    <script type="text/javascript">

但是,您的问题是仅根据特定用户角色应用此:

所以你得到:

// The jQuery Ajax request
function action_wp_footer() {
    // Only for logged in users
    if ( ! is_user_logged_in() )
        return;
    
    // Only checkout page
    if ( is_checkout() && ! is_wc_endpoint_url() ) :

    // Remove "ship_different" custom WC session on load
    if ( WC()->session->get( 'ship_different' ) ) {
        WC()->session->__unset( 'ship_different' );
    }
    
    // jQuery Ajax code below
