在WooCommerce签出时选中“发送到其他地址？”时，为特定用户角色添加费用

Question

我有一个批发网站与不同的用户角色

如果用户角色“team”和“team2”选择发送到不同的地址，我只想添加5美元的费用（如果发送到他们的账单地址，他们将获得免费发送）。

如果选择船舶到不同的地址，其他用户角色不应该看到费用。

这是我找到的最接近实现这一目标的解决方案，但需要帮助配置此代码，使其仅适用于这两个用户角色，而不适用于其他人。

// send as gift for Team & Team2 role add $5 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、缺失部分和不必要的步骤。

此答案显示（无任何用户限制）在选中“发送到其他地址”时如何添加费用：

// 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">
    jQuery( function($) {
        if ( typeof wc_checkout_params === 'undefined' )
            return false;

        var a = '#ship-to-different-address-checkbox', b = '';

        // Ajax function
        function triggerSTDA( value ) {
             $.ajax({
                type: 'POST',
                url: wc_checkout_params.ajax_url,
                data: {
                    'action': 'ship_different_address',
                    'ship_different': value,
                },
                success: function (result) {
                    $( 'body' ).trigger( 'update_checkout' );
                    // console.log( result ); // For testing (to be removed)
                }
            });
        }

        $( a ).on( 'change', function() {
            b = $( this ).prop('checked') === true ? 'yes' : 'no';
            triggerSTDA( b );
        });
    });
    </script>
    <?php
    endif;
}
add_action( 'wp_footer', 'action_wp_footer' );

// The Wordpress Ajax PHP receiver
function get_ajax_ship_different_address() {
    if ( isset( $_POST['ship_different'] ) ) {
        WC()->session->set( 'ship_different', esc_attr( $_POST['ship_different'] ) );
        echo $_POST['ship_different'];
    }
    
    die();
}
add_action( 'wp_ajax_ship_different_address', 'get_ajax_ship_different_address' );
add_action( 'wp_ajax_nopriv_ship_different_address', 'get_ajax_ship_different_address' );

// Add / remove a custom fee
function action_woocommerce_cart_calculate_fees( $cart ) {
    // Only on checkout
    if ( ( is_admin() && ! defined( 'DOING_AJAX' ) ) || is_cart() )
        return;

    $fee_amount = 5;

    if ( WC()->session->get( 'ship_different' ) == 'yes' ) {
        $cart->add_fee( __( 'Shipping fee', 'woocommerce'), $fee_amount );
    }
}
add_action( 'woocommerce_cart_calculate_fees', 'action_woocommerce_cart_calculate_fees', 10, 1 );

但是，您的问题是仅基于某些用户角色应用此功能：

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
    ?>
    <script type="text/javascript">
    jQuery( function($) {
        if ( typeof wc_checkout_params === 'undefined' )
            return false;

        var a = '#ship-to-different-address-checkbox', b = '';

        // Ajax function
        function triggerSTDA( value ) {
             $.ajax({
                type: 'POST',
                url: wc_checkout_params.ajax_url,
                data: {
                    'action': 'ship_different_address',
                    'ship_different': value,
                },
                success: function (result) {
                    $( 'body' ).trigger( 'update_checkout' );
                    // console.log( result ); // For testing (to be removed)
                }
            });
        }

        $( a ).on( 'change', function() {
            b = $( this ).prop('checked') === true ? 'yes' : 'no';
            triggerSTDA( b );
        });
    });
    </script>
    <?php
    endif;
}
add_action( 'wp_footer', 'action_wp_footer' );

// The Wordpress Ajax PHP receiver
function get_ajax_ship_different_address() {
    if ( isset( $_POST['ship_different'] ) ) {
        WC()->session->set( 'ship_different', esc_attr( $_POST['ship_different'] ) );
        echo $_POST['ship_different'];
    }
    
    die();
}
add_action( 'wp_ajax_ship_different_address', 'get_ajax_ship_different_address' );
add_action( 'wp_ajax_nopriv_ship_different_address', 'get_ajax_ship_different_address' );

// Add / remove a custom fee
function action_woocommerce_cart_calculate_fees( $cart ) {
    // Only on checkout
    if ( ( is_admin() && ! defined( 'DOING_AJAX' ) ) || is_cart() )
        return;
    
    // Only for logged in users
    if ( ! is_user_logged_in() )
        return;

    // Get current WP_User Object
    $user = wp_get_current_user();
    
    // Roles to check, adapt to your specific needes
    $roles_to_check = array( 'team', 'team2', 'administrator' );
    
    // User roles
    $roles = ( array ) $user->roles;
    
    // Compare
    $compare = array_diff( $roles, $roles_to_check );

    // Result is empty
    if ( empty ( $compare ) ) {
        // Amount
        $fee_amount = 5;

        if ( WC()->session->get( 'ship_different' ) == 'yes' ) {
            $cart->add_fee( __( 'Shipping fee', 'woocommerce'), $fee_amount );
        }
    }
}
add_action( 'woocommerce_cart_calculate_fees', 'action_woocommerce_cart_calculate_fees', 10, 1 );

部分用于此答案

• 根据Woocommerce中的签出字段显示隐藏支付网关
• 用于在WooCommerce中添加/删除自定义费用的复选框字段
• 检查WooCommerce用户角色和支付网关是否匹配-申请费用
