Question

我想为WORDPRESS创建一个脚本，该脚本可以按超过20天的角色（例如“订阅者”）删除用户。我搜索了一个插件，但我找不到。

我发现此脚本会按角色删除用户，但我想删除具有相同角色的超过20天的用户。

<?php
define( 'WP_USE_THEMES', false );
require( './wp-load.php' );

$role = "subscriber"; // The role to kill
$reassign = 1; // The user that all posts will fall back to, other wise they will be deleted

$this_role = "[[:<:]]$role[[:>:]]";

$query = $wpdb->prepare( "SELEC T user_id FROM $wpdb->usermeta WHERE meta_key = '{$wpdb->prefix}capabilities' AND meta_value RLIKE %s", $this_role );

if ( $users_of_this_role = $wpdb->get_results( $query, ARRAY_N ) )
    foreach ( $users_of_this_role as $user_id )
            wp_delete_user( $user_id[0], $reassign );

在WHERE子句中使用SELECT将帮助您实现所需的内容（删除超过X天数的用户）。根据您的需要调整代码（阅读内联注释以获得解释）。之后，在插件的文件夹中创建一个文件，并将其命名为delete_users.php。然后在WP Dashboard中添加以下代码，保存并将其作为插件激活。

delete_users.php

<?php
/**
 * Plugin Name: Delete old users
 * Plugin URI: http://stackoverflow.com/users/395160/manolis
 * Description: Delete users older than x amount of days
 * Version: 1.0
 * Author: Manolis
 * Author URI: http://stackoverflow.com/users/395160/manolis
 * License: GPL2
 */

if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');

global $wpdb;
require_once(ABSPATH.'/wp-admin/includes/user.php');

$role = "author"; // The role to kill
$reassign = 1; // The user that all posts will fall back to, other wise they will be deleted
$days = 20; // Calculated in days, how old a user should be in order to get deleted

$this_role = "[[:<:]]".$role."[[:>:]]";

$query = $wpdb->prepare("
    SELECT user_id
    FROM $wpdb->usermeta
    WHERE meta_key = '{$wpdb->prefix}capabilities'
    AND (SELECT user_id 
            FROM $wpdb->users 
            WHERE user_registered < NOW() - INTERVAL $days DAY
         )
    AND meta_value RLIKE %s", $this_role);


if ( $users_of_this_role = $wpdb->get_results( $query, ARRAY_N ) )
    foreach( $users_of_this_role as $user_id )
        wp_delete_user( $user_id[0], $reassign );

?>
