How do I get the absolute URL when using l()? I want to get &lt;a href="http://site.ru/node/123"&gt;New product&lt;/a&gt; from l(), and I
call it as l('New product', 'node/123'), but this function generates a URL that is not absolute.

How can I generate an absolute URL with l()?
You can make a link absolute with:

l(t('New product'), 'node/123', array('absolute' =&gt; TRUE));


See l() and url() for more.
