如果在WooCommerce中选中了checkout custom复选框，则更改用户角色 [英] Change user role if checkout custom checkbox is checked in WooCommerce

问题描述

我正在尝试将自定义功能添加到我的子主题functions.php文件中，其中在结帐页面上的帐单详细信息表单的底部添加了一个复选框.

I'm trying to add a custom function to my child-themes functions.php file where a checkbox is added to the bottom of the billing details form on the checkout page.

此复选框询问客户是否要成为批发客户.

This checkbox asks the customer if they'd like to become a wholesale customer.

function customise_checkout_field_with_wholesale_option($checkout) {

echo '<div id="wholesale_checkbox_wrap">';
woocommerce_form_field('wholesale_checkbox', array(
    'type' => 'checkbox',
    'class' => array('input-checkbox'),
    'label' => __('Would you like to apply for a wholesale account?'),
    'placeholder' => __('wholesale'),
    'required' => false,
    'value'  => true
), $checkout->get_value('wholesale_checkbox'));
echo '</div>';

}

这很好，但是我在下一部分中遇到了麻烦.

This works fine, however I'm having trouble with this next part..

我希望客户用户角色如果选中复选框，则另存为"wholesale_customer"而不是"customer".

I would like the customers user role to save as "wholesale_customer" instead of "customer" if they check the checkbox.

add_action('woocommerce_after_checkout_billing_form', 'customise_checkout_field_with_wholesale_option');

function wholesale_customer( $order_id ) {

$order = new WC_Order( $order_id );

if (isset($_POST['wholesale_checkbox'])) {

    if ($order->user_id > 0) {
        $user = new WP_User($order->user_id);
        // Remove role
        $user->remove_role('customer');
        // Add role
        $user->add_role('wholesale_customer');
    }
}
}
add_action( 'woocommerce_thankyou', 'wholesale_customer' );

当我删除批发_复选框if语句时，上述功能通过将客户另存为批发客户"而起作用.但是，如果包含if语句，它将始终将角色保存为客户".

The above function works by saving the customer as a "wholesale_customer" when I remove the wholesale_checkbox if statement. But with the if statement included, it always saves the role as "customer".

我要去哪里错了?干杯

推荐答案

以下是正确的方法:

add_action( 'woocommerce_after_order_notes', 'custom_checkout_field_with_wholesale_option' );
function custom_checkout_field_with_wholesale_option( $checkout ) {

    if( current_user_can( 'wholesale_customer' ) ) return; // exit if it is "wholesale customer"

    echo '<div id="wholesale_checkbox_wrap">';
    woocommerce_form_field('wholesale_checkbox', array(
        'type' => 'checkbox',
        'class' => array('input-checkbox'),
        'label' => __('Would you like to apply for a wholesale account?'),
        'placeholder' => __('wholesale'),
        'required' => false,
        'value'  => true
    ), '');
    echo '</div>';

}

// Conditionally change customer user role
add_action( 'woocommerce_checkout_update_order_meta', 'wholesale_option_update_user_meta' );
function wholesale_option_update_user_meta( $order_id ) {
    if ( isset($_POST['wholesale_checkbox']) ) {
        $user_id = get_post_meta( $order_id, '_customer_user', true ); // Get user ID
        if( $user_id > 0 ){
            $user = new WP_User($user_id);
            $user->remove_role('customer');
            $user->add_role('wholesale_customer');
        }
    }
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试并可以正常工作.

Code goes in function.php file of your active child theme (or active theme). Tested and works.
