【中文标题】在“运送到其他地址？”时为特定用户角色添加费用？已在 WooCommerce 结帐时检查

【英文标题】：Add a fee for specific user roles when "Ship to a different address?" has been checked on WooCommerce checkout

【发布时间】：2022-01-07 13:57:34

【问题描述】：

我有一个具有不同用户角色的批发网站，并希望允许员工也从这里开始在线订购。

如果用户角色“团队”和“团队 2”选择运送到不同的地址（如果发送到他们的帐单邮寄地址，他们可以免费送货），我只想添加 5 美元的费用。

如果选择运送到其他地址，其他用户角色不应看到费用。

这是我发现的最接近的解决方案，但需要帮助配置此代码以仅适用于这两个用户角色，而不适用于其他用户角色。

// 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);

【参考方案1】：

您的代码包含一些错误、缺失的部分和不必要的步骤。

此答案显示（没有任何用户限制）在“运送到其他地址？”时如何添加费用？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">
    jQuery( function($) 
        if ( typeof wc_checkout_params === 'undefined' )

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,
                ,

        $( a ).on( 'change', function() 
            b = $( this ).prop('checked') === true ? 'yes' : 'no';

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();

    $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 );
