讓wordpress支持中文用戶名的簡便方法
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
- 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);
