php - 如何修改 sanitize_user WordPress 函数以接受西里尔文的用户名

问题描述

原始功能：

function sanitize_user( $username, $strict = false ) {
$raw_username = $username;
$username     = wp_strip_all_tags( $username );
$username     = remove_accents( $username );
// Kill octets.
$username = preg_replace( '|%([a-fA-F0-9][a-fA-F0-9])|', '', $username );
// Kill entities.
$username = preg_replace( '/&.+?;/', '', $username );

// If strict, reduce to ASCII for max portability.
if ( $strict ) {
    $username = preg_replace( '|[^a-z0-9 _.\-@]|i', '', $username );
}

$username = trim( $username );
// Consolidate contiguous whitespace.
$username = preg_replace( '|\s+|', ' ', $username );

/**
 * Filters a sanitized username string.
 *
 * @since 2.0.1
 *
 * @param string $username     Sanitized username.
 * @param string $raw_username The username prior to sanitization.
 * @param bool   $strict       Whether to limit the sanitization to specific characters.
 */
return apply_filters( 'sanitize_user', $username, $raw_username, $strict );

当用户执行注册时，我想修改它以接受西里尔文（塞尔维亚语）的用户名。

解决方案

function mujuonly_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
    // If strict, reduce to ASCII and Cyrillic characters for maximum portability.
    if ( $strict )
        $username = preg_replace( '|[^a-zа-я0-9 _.\-@]|iu', '', $username );

    $username = trim( $username );

    // Consolidate contiguous whitespace
    $username = preg_replace( '|\s+|', ' ', $username );

    return $username;
}

add_filter( 'sanitize_user', 'mujuonly_sanitize_user', 10, 3 );

试试这个 -使用 WP 5.6 测试正常
