Drupal: Creating anchor only link with l()

Question

I'd like to output this

<a href='#namedanchor'>link</a>

using the l() function, so that the link just jumps to an anchor on the current page.

I expected this to work

l('link', '',  array('fragment' => 'namedanchor'));

but it creates an absolute link to www.example.com/#namedanchor instead of www.example.com/currentpage#namedanchor

Answer 1

If you want to create a link with just the fragment, you need to "trick" the url function a bit. As it will append the basepath to all internal urls, '' will become http://example.com.

What you need to do is to set the external option to true:

l('link', '',  array('fragment' => 'namedanchor', 'external' => TRUE));

This will give the desired

<a href='#namedanchor'>link</a>

Alternative you could give the full url like Jeremy suggests.
