wp_safe_redirect( string $location, int $status = 302, string $x_redirect_by = 'WordPress' )

Performs a safe (local) redirect, using wp_redirect().

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

$location

(string) (Required) The path or URL to redirect to.

$status

(int) (Optional) HTTP response status code to use. Default '302' (Moved Temporarily).

Default value: 302

$x_redirect_by

(string) (Optional) The application doing the redirect.

Default value: 'WordPress'

Return

(bool) $redirect False if the redirect was cancelled, true otherwise.
