您需要的功能是wpmu_delete_user($user->ID)
我编写了一个小插件，用于按角色删除整个网络中的用户：
<?php
/**
* Plugin Name: Regbox Delete multisite users
* Plugin URI: http://www.regbox.se/delete-multisite-users
* Description: Delete users by role across network
* Version: 0.1
* Author: Adam Rehal
* Author URI: http://www.regbox.se

// Make admin menu item in Users
add_action(\'admin_menu\', \'dmu_submenu_page\');
function dmu_submenu_page() {
add_submenu_page( \'users.php\', \'Delete multisite users\', \'Delete users\', \'manage_options\', \'delete-multisite-users\', \'dmu_callback\' );
}
function dmu_callback() {
echo \'<div class="wrap"><div id="icon-tools" class="icon32"></div>\';
echo \'<h2>Delete multisite users</h2>\';
echo \'<p>Delete users by role across network. This will delete all users with the selected role from the current site AND from the network</p>\';
echo \'<p>Users with the same role on other sites will not be removed. You can also use the Count button to count the number of users with a specific role</p>\';
echo \'</div>\';
// Get all roles
global $wp_roles;
$roles = $wp_roles->get_names();
// Get all blogs
$blog_list = get_blog_list( 0, \'all\' ); ?>
<form method="get" action="users.php?page=delete-multisite-users">
<input type="hidden" name="page" value="delete-multisite-users">
<input id="what-to-do" type="hidden" name="action" value="">
<!--
Select blog:
<select name="blog">
<?php
foreach ($blog_list as $blog) { ?>
<option value="<?php echo $blog[\'blog_id\'];?>"><?php echo str_replace(\'/\',\'\',$blog[\'path\']);?></option>
<?php }//end foreach ?>
</select><br>
-->
Select Role:
<select name="role">
<?php foreach($roles as $role_value => $role_name) { ?>
<option value="<?php echo $role_value;?>"><?php echo $role_name;?></option>
<?php }//end foreach ?>
</select>
<input class="button button-secondary" onClick="javascript:document.getElementById(\'what-to-do\').value = \'delete\';" type="submit" value="Delete">
<input class="button button-primary" onClick="javascript:document.getElementById(\'what-to-do\').value = \'count\';" type="submit" value="Count">
</form>
<?php
// Needed to make use of wp_delete_user()
require_once( ABSPATH . \'/wp-admin/includes/user.php\' );
$data = new WP_User_Query( array( \'role\' => $_GET[\'role\']) );
$userList = $data->get_results();
$deleted = 0;
$counted = 0;
if($_GET[\'action\'] == \'delete\'){
if($_GET[\'role\'] != \'administrator\'){
foreach ($userList as $u) {
if(wpmu_delete_user( $u->ID )){ $deleted++; }
}
echo "<p>" . $deleted . " user(s) deleted</p>";
}else {
echo "<p>Admin cannot be deleted</p>";
}
}
if($_GET[\'action\'] == \'count\'){
foreach ($userList as $u) {
$counted++;
}
echo "<p>" . $counted . " " . $_GET[\'role\'] . " user(s) on current site</p>";
}
}
