将新角色批量添加到 WooCommerce 用户列表

Question

我有一个从我们的 WooCommerce 网站购买产品的 141 位客户的列表。我使用 UserInsights 插件 (https://usersinsights.com/) 提取了列表。

我想要做的是在这些用户拥有的任何内容之上批量添加不同的角色，如果他们已经拥有新角色，则根本不对该特定用户执行任何操作。

使用来自 UserInsights (https://usersinsights.com/woocommerce-change-customer-role/) 的这篇文章，我尝试将以下代码添加到我的 functions.php 中，它显示代码已执行，但用户从未收到新角色。

这是我添加到我的functions.php中的代码：

function uiwc_set_custom_role() {
  //the slug of our newly created group
  $group_slug = 'homeschool-strong';

  //the role we want to change our users to
  $user_role = 'homeschool-strong';

  //telling WP which taxonomy we're looking into
  $taxonomy = 'usin_group';

  //getting the UI group information
  $term = get_term_by( 'slug', $group_slug, $taxonomy, 'ARRAY_A' );

  // getting the users from that group
  $id = $term['term_id'];
  $out = get_objects_in_term( $id, $taxonomy );

  //checking if there are any users
  if( ! empty( $out ) ) {

    //let's loop trhough all users
    foreach ( $out as $uid) {
  //get the user related to this ID
  $user = new WP_User($uid);

  //do not change the role of admins
  if( !user_can($user, 'administrator') ){
    //set the new role to our customer
    $user->$user->add_role($role);
  }

}

// just so you know the code worked
echo "<script>alert('code run');</script>";
}
 }

add_filter('admin_footer', 'uiwc_set_custom_role');

有人知道为什么在执行这段代码时新角色没有添加到用户吗？或者，也许您知道将新角色添加到 WooCommerce 用户列表的更好方法？

在 kashalo 的帮助下，最终的代码是：

function uiwc_set_custom_role()
 {
//the slug of our newly created group
$group_slug = 'homeschool-strong';

//the role we want to change our users to
$user_role = 'homeschool-strong';

//telling WP which taxonomy we're looking into
$taxonomy = 'usin_group';

//getting the UI group information
$term = get_term_by('slug', $group_slug, $taxonomy, 'ARRAY_A');

// getting the users from that group
$id = $term['term_id'];
$out = get_objects_in_term($id, $taxonomy);

//checking if there are any users
if (!empty($out)) {

    //let's loop trhough all users
    foreach ($out as $uid) {
        //get the user related to this ID
        $user = new WP_User($uid);

        //do not change the role of admins
        if (!user_can($user, 'administrator')) {
            //set the new role to our customer
            $user->add_role($user_role);
        }

    }

// just so you know the code worked
    echo "<script>alert('code run');</script>";
   }
}

add_filter('admin_footer', 'uiwc_set_custom_role');

您的代码中有两个问题

这一行：

$user->$user->add_role($role);

应该如下：

$user->add_role($user_role);

说明您使用该对象两次，并且您没有定义已声明为 user_role 的变量角色

第二期：

$user_role = 'homeschool-strong';

在您的声明中，WordPress 将被视为数组而不是字符串，所以它应该是这样的：

$user_role = 'homeschool_strong';

所以完整的代码应该是这样的：

function uiwc_set_custom_role()
{
    //the slug of our newly created group
    $group_slug = 'homeschool-strong';

    //the role we want to change our users to
    $user_role = 'homeschool_strong';

    //telling WP which taxonomy we're looking into
    $taxonomy = 'usin_group';

    //getting the UI group information
    $term = get_term_by('slug', $group_slug, $taxonomy, 'ARRAY_A');

    // getting the users from that group
    $id = $term['term_id'];
    $out = get_objects_in_term($id, $taxonomy);

    //checking if there are any users
    if (!empty($out)) {

        //let's loop trhough all users
        foreach ($out as $uid) {
            //get the user related to this ID
            $user = new WP_User($uid);

            //do not change the role of admins
            if (!user_can($user, 'administrator')) {
                //set the new role to our customer
                $user->add_role($user_role);
            }

        }

// just so you know the code worked
        echo "<script>alert('code run');</script>";
    }
}

add_filter('admin_footer', 'uiwc_set_custom_role');

我只是测试了代码，它正在工作
