Let us learn more about the wp_redirect in wordpress. With the support of our WordPress support services at Bobcares, we can go through the complete setup process.

wp_redirect wordpress

In WordPress, wp_redirect is a function that allows users to redirect visitors from one page or URL to another. We can use this function to redirect users after they have put up a form or taken some other action on the website.

wp_redirect( string $location, int $status = 302, string $x_redirect_by = 'WordPress' ): bool

Please keep in mind that wp redirect() does not automatically exit and should nearly always be accompanied by a call to exit:

wp_redirect( $url ); exit; Exiting may also be controlled selectively by combining wp redirect() as a conditional with the 'wp redirect' and ‘wp redirect location’ filters:

if ( wp_redirect( $url ) ) { exit; }

function wp_redirect( $location, $status = 302, $x_redirect_by = 'WordPress' ) {
global $is_IIS;
/**
* Filters the redirect location.
*
* @since 2.1.0

$status = apply_filters( 'wp_redirect_status', $status, $location );
if ( ! $location ) {
return false;
}
if ( $status < 300 || 399 < $status ) {
wp_die( __( 'HTTP redirect status code must be a redirection code, 3xx.' ) );
}
$location = wp_sanitize_redirect( $location );
if ( ! $is_IIS && 'cgi-fcgi' !== PHP_SAPI ) {
status_header( $status ); // This causes problems on IIS and some FastCGI setups.
}
/**

$x_redirect_by = apply_filters( 'x_redirect_by', $x_redirect_by, $status, $location );
if ( is_string( $x_redirect_by ) ) {
header( "X-Redirect-By: $x_redirect_by" );
}
header( "Location: $location", true, $status );
return true;
}

apply_filters( 'wp_redirect_status', int $status, string $location )

Filters the HTTP response status code to use for redirects.

apply_filters( 'x_redirect_by', string $x_redirect_by, int $status, string $location )
