Because that’s how it is coded.
What do you want? I mean what is your end goal and why? Don’t go technical, just explain WHAT you want and ask for the HOW; don’t assume you know it.
heh, i’ve read to change it in wp-includes\classes.php .. ?!
i’d like to use ?id instead of ?page_id as parameter in my url
because google sitemap listed my old site with “?id” links.
well, that’s a good reason, but your better solution is to do 301 redirects in your htaccess file.
ask google about it, there are guides upon guides on how to do this.
I assume your ID numbers are the same right? well, a redirect specified as a regular expression will reuse the incoming IDs, but change the URLs.
thanks, that helped me alot 🙂
