检查WooCommerce用户角色和支付网关，以及它们是否匹配-收取费用 [英] Check WooCommerce User Role and Payment Gateway and if they match - Apply fee

问题描述

如果选择了特定的支付网关，我将努力向一系列用户角色收取费用。

I'm struggling with applying a fee for an array of user roles if and when a specific payment gateway is selected.

我编写的代码效果很好如果我不检查用户角色，但是一旦尝试了就不会。

The code I've written works fine if I do not check the user role, but once I try and do that, it does not.

我已删除（评论）用户角色 if 语句中的代码，我正在寻求帮助使其正常工作。

I've removed (commented) the user role if statement in the code and I'm asking for help making it work.

我需要检查用户角色是否与我的角色匹配数组，如果有，请检查支付网关。如果付款网关也匹配，请收取费用。

I need to check if the user role match my array and if it does, check the payment gateway. If the payment gateway match too, apply the fee.

这是我的代码：

add_action( 'woocommerce_cart_calculate_fees', 'custom_fee', 20, 1 );
function custom_fee ($cart){

    if (is_admin() && !defined('DOING_AJAX')) return;

    if (!is_user_logged_in()) return;

    if (!is_checkout() && !is_wc_endpoint_url()) return;

    $customer_role = wp_get_current_user();
    $roles_to_check = array( 'vendor', 'external' );
    $payment_method = WC()->session->get('chosen_payment_method');

        // if (!in_array($roles_to_check, $customer_role->roles)) return;

    if ('bacs' == $payment_method){
        $payment_fee = $cart->subtotal * 0.05;
            $cart->add_fee( 'Payment Fee', $payment_fee, true );
    }
}

推荐答案

您可以使用以下解释，并在代码中添加注释：

You could use the following, explanation with comments added in the code

此代码中必须满足的条件是：

Conditions that must be met in this code are:

• 仅适用于某些用户角色


• 检查付款方式

function custom_fee( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;
    
    if ( ! ( is_checkout() && ! is_wc_endpoint_url() ) )
        return; // Only checkout page
    
    if ( ! is_user_logged_in())
        return;

    // Get current WP_User Object
    $user = wp_get_current_user();
    
    // User roles
    $roles = ( array ) $user->roles;

    // Roles to check
    $roles_to_check = array( 'vendor', 'external', 'administrator' );
    
    // Compare
    $compare = array_diff( $roles, $roles_to_check );

    // Result is empty
    if ( empty ( $compare ) ) {
        // Payment method
        $payment_method = WC()->session->get('chosen_payment_method');

        // Condition equal to
        if ( $payment_method == 'bacs' ) { 
            // Calculate
            $payment_fee = $cart->subtotal * 0.05;

            // Add fee
            $cart->add_fee( 'Payment Fee', $payment_fee, true );
        }
    }
}
add_action( 'woocommerce_cart_calculate_fees', 'custom_fee', 10, 1 );
