sanitize_user
function has a sanitize_user
filter. The filter gives you $username, $raw_username, $strict from the sanitize_user
and expects you to return $username, according to the inline documentation:
/**
* 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 $strict Whether to limit the sanitization to specific characters. Default false.
*/
You would do something like:
function wpse_283736_sanitize_user_filter($username){
// do your sanitization with $username
return $username;
}
add_filter('sanitize_user', 'pse_283736_sanitize_user_filter''wpse_283736_sanitize_user_filter');
Or like this
function wpse_283736_sanitize_user_filter($username, $raw_username, $strict){
// do your sanitization with $username or maybe $raw_username
return $username; // or return $raw_username;
}
add_filter('sanitize_user', 'pse_283736_sanitize_user_filter''wpse_283736_sanitize_user_filter', 10, 3);
You could hook to pre_user_login
filter, available on wp_insert_user
function, which is used by Woocommerce user registration process.
$pre_user_login = apply_filters( 'pre_user_login', $sanitized_user_login );
$pre_user_login = apply_filters( 'pre_user_login', $sanitized_user_login );
function wpse_283736_pre_user_login_filter($sanitized_user_login){
// do your sanitization with $sanitized_user_login
return $sanitized_user_login;
}
add_filter('pre_user_login', 'pse_283736_pre_user_loginr_filter''wpse_283736_pre_user_login_filter', 10, 3);
