The following code works for me to redirect the user back to the previous current page after he/she logs in.
<?php
print l(t('Please Log in'),'/user/login', array(
'attributes' => array('title' => t('Log in page')),
'query' => drupal_get_destination()));
?>
However, how can I add #
to the previous current page?
For example, if the user was on /node/1 and go to the login page. Then How can I redirect this user to /node/1#article_1 ?
(How can I add this #article_1? )
