Question

I am upgrading a CMS that used

$logged_in = user_external_login($account);

to verify a login after they hit an external service.

http://drupal.org/update/modules/6/7 suggested this solution

   user_login_submit(array(), array('uid' => $account->uid));
   drupal_goto(); 

This throws a “Only variables can be passed by reference” error at runtime. I am unsure what else to do. Looking around like here http://drupal.org/node/497612 the same solution is suggested. Can someone please fill me in on what I am missing.

Answer 1

For this line:

 user_login_submit(array(), array('uid' => $account->uid));

… it expects the second parameter to be a reference. What you gave it was a value, which is not a reference.

Try this instead:

$account = array('uid' => $account->uid);
user_login_submit(array(), $account);
// rest of your code follows after...

I think the documentation is messed up on Drupal.org. user_login_submit(array(), array('uid' => $account->uid)); is not correct, unless I missed something.
