Print login page url in node.tpl.php It seems nevertheless rather simple, but I do not find the solution. 

How to print in node.tpl.php the url of the login page? 

The url has to serve for a link:

&lt;a href="&lt;?php print ... ?&gt;"&gt;&lt;span&gt;Login&lt;/span&gt;&lt;/a&gt;
Use this if you just want the URL:

&lt;?php print url('user/login'); ?&gt;


If you want to print a link:

&lt;?php print l(t('Login'), 'user/login'); ?&gt;


And in your case it would be:

&lt;?php print l('&lt;span&gt;' . t('Login') . '&lt;/span&gt;', 'user/login', array('html' =&gt; TRUE)); ?&gt;
