我注意到我们的朋友共享的代码有一个错误。添加前缀两次。

我共享了其他代码并解决了此错误。

<?php


add_filter( \'pre_user_login\', \'sneakily_add_prefix_to_username\' );

function sneakily_add_prefix_to_username( $username ) {
    if ( ! current_user_can( \'manage_network\' ) ) {
        $blog_id = get_current_blog_id();
        $blog_details = get_blog_details( $blog_id );
        $sanitized_path = str_replace( \'/\', \'\', get_blog_details()->path );
        //error_log($sanitized_path);
        if ( $sanitized_path != \'\') {
            if(false === stripos($username, $sanitized_path)) {
                return $sanitized_path . \'-\' . $username;
            } else {
                return $username;
            }
        } else {
            $domain_parts = explode( \'.\', $blog_details->domain );
            if ( is_array( $domain_parts ) ) {
                $sanitized_subdomain = sanitize_user( $domain_parts[0], true );
                //error_log($sanitized_subdomain);
                if ( $sanitized_subdomain != \'\' ) {
                    if(false === stripos($username, $sanitized_subdomain)) {
                        return $sanitized_subdomain . \'-\' . $username;
                    } else {
                        return $username;
                    }
                }

我不确定他们是否会喜欢这个前缀，也许他们更愿意使用一个未使用的新用户名。但在这里，我是按照你的意愿做的。它要么采用站点的路径，要么采用子域的第一部分，因此它适用于这两种类型的多站点。它影响非超级管理员用户创建的用户。
