I will try following code for redirect in wordpress admin.
if(isset($_POST['submit']))
{
wp_redirect('admin.php?page=job-creation');
}
i also try wp_redirect('admin.php?page=job-creation');
instead of
wp_safe_redirect('admin.php?page=job-creation');
and
header('location: admin.php?page=job-creation');
All codes are working fine in localhost. but it does not working in online(www.example.com).
Help me anyone.
