[wp-hackers] what function creates the post slug?

[Ricardo Moraleida]

While 3.3 isn't here, though, i got into Dion's wp_insert_post_data filter
suggestion and got this to work:

*function rm_martins_cpt_permalink_change($data, $postarr) {*
* *
* if ($data['post_type'] == 'post_type_name') {*
*
*
*                $time = time();*
* $data['post_name'] = md5($time);*
* return $data;*
* } else {*
*            return $data;*
*        }*
*}*
*add_filter('wp_insert_post_data','rm_martins_cpt_permalink_change',10,2);*

this solution was partly borrowed from a function in wp-includes\ms.php
(line 590 or so) that checks for colliding permalinks over a blog network,
pretty neat.

It just replaces the original post slug with the md5 hash for the unix
timestamp of the last post data insertion, which seems random enough for me
and i hope won't cause me trouble when listing posts in the future.

So, just thought it might be useful to post my result function here, though
it has not been thoroughly tested so far.

thanks for the help!
