wp_safe_redirect( string $location, int $status = 302, string $x_redirect_by = 'WordPress' )
Performs a safe (local) redirect, using wp_redirect().
Description Description
Checks whether the $location is using an allowed host, if it has an absolute path. A plugin can therefore set or remove allowed host(s) to or from the list.
If the host is not allowed, then the redirect defaults to wp-admin on the siteurl instead. This prevents malicious redirects which redirect to another host, but only used in a few places.
Note: wp_safe_redirect() does not exit automatically, and should almost always be followed by a call to exit;:
wp_safe_redirect( $url );
exit;Exiting can also be selectively manipulated by using wp_safe_redirect() as a conditional
in conjunction with the ‘wp_redirect’ and ‘wp_redirect_location’ filters:
if ( wp_safe_redirect( $url ) ) {
exit;
}Parameters Parameters

As with
wp_redirect, unless this is patched to perform this natively in the future, be sure to includenocache_headers();before thewp_safe_redirectif you want to make sure the visitor’s browser doesn’t cache the redirect page result (can even happen when this is set to use a 302 redirect) which may cause the redirect to happen for longer than desired.For example, this can be problematic when used to redirect to a login page when trying to access protected content since the visitor can then log in to find that they’re still taken back to the login page when trying to go back to that page they were trying to go to due to the redirect having been potentially cached by their web browser (again, even with it being a 302 redirect.) Having
nocache_headers();before the redirect prevents this potential issue.Feedback
Ticket #50422 is looking to address this natively for future versions of WordPress so this may not be required in the future, but this is advisable/required for now and shouldn’t be problematic if/when WordPress chooses to adopt the proposed update. — By KZeni —
To add additional domains to the list of allowed hosts, use the allowed_redirect_hosts filter.
