My writer has a tendency to add extra newlines (Enter key) and spaces (space bar) at the ends of posts. Sometimes this results in inches of extra whitespace onscreen!

Is there a way I can make sure extra trailing whitespace is removed when he hits "Update" in the Wordpress post editor?

Quick guess would be:

add_filter('content_save_pre', 'trim');

Add to functions.php of theme or wherever is appropriate in your site.

Doesn't work. Maybe it's because the post is still full of trailing  s ? – a paid nerd Aug 30 '11 at 4:16
@a paid nerd likely that. trim() only removes true whitespace. It worked for me in quick test, but I used HTML editor. Likely your writer is using visual one that encodes spaces. You will need to hook your own function that will delete (or convert to regular spaces before trim) those entities. – Rarst♦ Aug 30 '11 at 8:49
