Sometimes you'll need to create a menu link that is different for each user that views it. The simplest way to do this is to create a small custom module that will add the menu link and generate a dynamic URL.

In my case, I wanted a link title 'My Company' that would redirect the user to their own Organic Group.

What to do

• Create a menu entry

  ```
  function grasmash_menu() {
  //create menu item for My Company
  $items = array();

  $items['my-company'] = array(
  'title' => 'My Company',
  'description' => 'View your company\'s page',
  'page callback' => 'grasmash_my_company_link',
  'access callback' => 'grasmash_user_has_company',
  'expanded' => TRUE,
  'weight' => -100,
  'menu_name' => 'primary-links',
  );

  return $items;
  }

  ?>
  ```
  The page and access callbacks are functions that I'm about to create. For more information about the hook_menu function, checkout the hook_menu() entry in Drupal's API. I'd also recommend downloading the Examples for Developers module to get a good sense of how Drupal's basic functions work.

• Next, create a function that will actually determine the user's company (OG)
  ```
  //find user's company. this assume that each user only belongs to one company!
  //for admins, will choose the most recently joined company that user is an admin of
  function grasmash_get_user_company(){
  global $user;
  $nid = db_result(db_query("SELECT og_uid.nid, node.type FROM og_uid, node WHERE og_uid.uid = %d AND node.type = 'company' AND node.nid = og_uid.nid ORDER BY og_uid.created DESC, og_uid.is_admin DESC LIMIT 1", $user->uid));
  return $nid;
  }
  ?>
  ```
• Let's also create function for the access callback. This will determine whether the user should be able to see the link.
  ```
  //does the user actually belong to a company?
  function grasmash_user_has_company(){
  if (grasmash_get_user_company()){
  return TRUE;
  }
  }
  ?>
  ```
• Lastly, let's redirect the user to the correct node after they click on the link:
  ```
  //redirect the user to the right node
  function grasmash_my_company_link(){
  $nid = grasmash_get_user_company();
  drupal_goto('node/' . $nid);
  //return node_view($nid); //you could also simply load the node if you wanted to
  }
  ?>
  ```

And there you have it. Feel free to customize the MySQL query to change which node the user will be redirected to.

A quick note on what we didn't do

We didn't add code that would dynamically change the $items['my-company'] URL. Why? because Drupal only checks on that URL when the menu system needs to be rebuilt. Instead, you need to choose a static URL and write a function that will dynamically load content or redirect the user when that URL is visited.
