append data in user global variable?

Question

Is there any way that i can append my data into user global variable so i can access it on other pages?

Answer 1

You have two options

• You can save it on the user object ($user->data), if it's some static data that doesn't change.

• Use hook_user op load which could look like this:

  function module_user($op, &$edit, &$account, $category = NULL) {
    switch ($op) {
      case 'load':
        $account->module = db_fetch_object(db_query(
          'SELECT * FROM {module} WHERE uid = %d', $account->uid
        ));
        break;
    }
  }
  

Hook user, is good if you have complex data that changes a lot. You can store the data in your own table, and append it you the user when it's being loaded. The downside is, that you will need to run user_load you get the data on the user object.

Answer 2

If you don't need/want to handle the storage of your data in the database because you just want it the be globally accessible during the user's session, you can store it in the $_SESSION array.

Answer 3

You can also use variable_set() and variable_get()if the data is common to all users else SESSIONS need to be used
