Redirect anonymous user to login page

Question

I need to redirect an anonymous user when they hit the url 'node/add/project' to 'user/login' - otherwise, just leave them enter that url.

Not sure if I'm going about this the correct way (probably not as it doesn't appear to work!) - Can someone shed some light, or advice!

function local_menu() {
    $items['node/add/project'] = array(
        'page callback' => 'local_project_anonymous',
        'access callback' => TRUE,
        'type' => MENU_CALLBACK,
    );

    return $items;
}

function local_project_anonymous(){
    global $user;
    if($user->uid == 0){
        drupal_goto('user/login');
    }   
}

Cheers

Answer 1

function MODULE_init(){
  global $user;
  if ($user->uid == 0  && $_GET['q'] == 'node/add/project' ) {
    drupal_goto('user/login');
  }
}

Maybe you can use the LoginToboggan module.

The LoginToboggan module offers several modifications of the Drupal login system in an external module by offering the following features and usability improvements:

• Allow users to login using either their username OR their e-mail address.
• Allow users to login immediately.
• Provide a login form on Access Denied pages for non-logged-in (anonymous) users.
• The module provides two login block options: One uses JavaScript to display the form within the block immediately upon clicking "log in". The other brings the user to a separate page, but returns the user to their original page upon login.
• Customize the registration form with two e-mail fields to ensure accuracy.
• Optionally redirect the user to a specific page when using the 'immediate login' feature.
• Optionally redirect the user to a specific page upon validation of their e-mail address.
• Optionally display a user message indicating a successful login.
• Optionally combine both the login and registration form on one page.
• Optionally have unvalidated users purged from the system at a pre-defined interval.
• Integrates with the Rules module to do various tasks when a user validates via email validation process (see http://drupal.org/node/880904 for an example).
