[wp-hackers] more nofollow

[Robert Deaton]

Has anyone on this list yet tried to make a plugin to remove nofollow?
I just sat down for the last hour or so looking over many little bits
of core code and have found it to be impossible due to the filter on
get_comment_author_link() and its general method, without using regex
to manually cut out the nofollow mess. I did however get it to remove
nofollow on links in the comment text, so it can at least be partly
undone.

Here's what I did for the comment text:
//This is a duplicate of the original function make_clickable before
nofollow support was added.
function no_nf_make_clickable($ret)
{
	$ret = ' ' . $ret . ' ';
	$ret = preg_replace("#([\s>])(https?)://([^\s<>{}()]+[^\s.,<>{}()])#i",
"$1<a href='$2://$3'>$2://$3</a>", $ret);
	$ret = preg_replace("#(\s)www\.([a-z0-9\-]+)\.([a-z0-9\-.\~]+)((?:/[^
<>{}()\n\r]*[^., <>{}()\n\r]?)?)#i", "$1<a
href='http://www.$2.$3$4'>www.$2.$3$4</a>", $ret);
	$ret = preg_replace("#(\s)([a-z0-9\-_.]+)@([^,< \n\r]+)#i", "$1<a
href=\"mailto:$2@$3\">$2@$3</a>", $ret);
	$ret = trim($ret);
	return $ret;
}

	remove_filter('comment_text', 'make_clickable');
	add_filter('comment_text', 'no_nf_make_clickable');
