Thanks am Grateful with your support am able to redirect while sending refering page also, just little modification of code give
add_action('init' , 'geodir_redirect_to_default_login') ;
function geodir_redirect_to_default_login()
{
if(isset( $_REQUEST['geodir_signup']))
{
wp_redirect(home_url().'/wp-login.php?redirect_to='<strong>.$_SERVER['HTTP_REFERER']</strong>);
exit();
}
}
By default Userultra redirect login to profile or custom page but not refering page. so adding .$_SERVER[‘HTTP_REFERER’] just help a little.
I just add this in case someome might need it
