今天微码盒介绍新的方法,借鉴了 wp-includes/formatting.php 中 sanitize_user 函数的写法,同样是将以下 php 代码复制到当前主题目录下的 functions.php 中,即可让 WordPress 支持使用中文用户名注册和登录:
代码如下:
function ludou_sanitize_user ($username, $raw_username, $strict) { $username = wp_strip_all_tags( $raw_username ); $username = remove_accents( $username ); // Kill octets $username = preg_replace( '|%([a-fA-F0-9][a-fA-F0-9])|', '', $username ); $username = preg_replace( '/&.+?;/', '', $username ); // Kill entities // 网上很多教程都是直接将$strict 赋值 false, // 这样会绕过字符串检查,留下隐患 if ($strict) { $username = preg_replace ('|[^a-z\p{Han}0-9 _.\-@]|iu', '', $username); } $username = trim( $username ); // Consolidate contiguous whitespace $username = preg_replace( '|\s+|', ' ', $username ); return $username; } add_filter ('sanitize_user', 'ludou_sanitize_user', 10, 3);
