Make blogroll links no-follow?

Question

How can I add a nofollow option to my blogroll links editor?

Attempted to just type "nofollow" into the "rel" input box, but its auto deleted onblur.

If I turn javascript off (thanks to Matt's suggestion below), It works, but when I check the source on my site, the rel attribute looks like this...

rel="nofollow"onclick="javascript:pageTracker._trackPageview('/outbound/blogroll/www.site.com');

Answer 1

I know of three ways around this and unfortunately they all suck:

1. Hack a core file
2. Use a plugin
3. Temporarily turn off scripgs in your browser and change them in the edit links section.

Answer 2

You can filter your blogroll to make all links nofollow with a function like this:

function nofollow_blogroll( $html ) {
    // remove existing rel attributes
    $html = preg_replace( '/\s?rel=".*"/', '', $html );
    // add rel="nofollow" to all links
    $html = str_replace( '<a ', '<a rel="nofollow" ', $html );
    return $html;
}
add_filter( 'wp_list_bookmarks', 'nofollow_blogroll' );

If you need to do it on a case-by-case basis, though, you're probably stuck with some hacks like @matt pointed out.
