How to redirect to l() function link after login?

Question

I'm having a Simplenews newsletter template with a link guiding newsletter readers to a intranet site with more news.

<?php print l('hier.', 'node/' . $build['#node']->nid, array('absolute' => TRUE)); ?>

My problem now is, that if the user is not logged in, that link only brings him to the login site, where he is then stucked.

What would I have to do or what function would help me to somehow provide a link that redirects the not logged in user to the proper aim after logging in, and which would not affect the already logged in user?

Answer 1

You can add a additional destination parameter to the function.

<?php
print l(t('Title'), 'url', array('query' => array('destination' => 'destination_url')))
?> 

This will create :

<a href="url?destination=destination_url">Title</a>

Hope it helps.
