Drupal 6 template redirect

Question

There are a few solutions to redirect if user is not logged in. What if I do not wish to redirect to login page but to main domain webpage

So here this is easy, drupal goto brings us to domain/user/login, but i want redirect to go to domain. Of course, drupal_goto(''); causes an error!

 global $user;
   if ($user->uid == 0 && arg(0) != 'user' && arg(1) != 'login'){
   drupal_goto('user/login');
 }

(this is placed in theme template.php file under function phptemplate_preprocess_page(&$vars) )

Answer 1

Well the easiest way is to add the destination parameter to the log out link.

So if your link looks like example.com/logout change it to example.com/logout&destination=node/1. After you logout, Drupal will automatically redirect you to the destination. Generating the links is very easy as well, something like this:

  <?php if ($user->uid) : ?>
    <?php print l(t('log out'), 'logout', array('query' => drupal_get_destination())); ?>
    <?php print l($user->name, 'user'); ?>
  <?php else : ?>
    <?php print l(t('log in'), 'user', array('query' => drupal_get_destination())); ?>
  <?php endif; ?>
