3. hi, lester
   the code within your post seems beautiful, how can I do that? use a code highlight plugins or manually edit css file?

4. I am using WP-Syntax, http://wordpress.org/extend/plugins/wp-syntax/

5. thanks, It is a nice plugin!

6. Thanks a ton for your help.
   I went mad afer upgrading to WP 2.6.
   I added define (‘WP_POST_REVISIONS’, 0); in my WP-CONFIG file but I am still seeing the autosave functionality.
   Is there any other trick ?

7. it will still autosave, but it will not create the revisions

8. Thanks a lot, Lester! Disabling and then deleting all those revisions cut my db size in half!

9. Will it be the same if you just change the WP_POST_REVISIONS in wp-settings.php from true to false?

10. It is not recommended to touch the core files as you will lose them if you upgrade

11. I really need this post. I don’t know about this feature, usefull or useless..
    Many thanks….

14. What is the difference to this code?

    DELETE FROM wp_posts WHERE post_type = “revision”;

    which I found here?

15. That code will only delete away the revisions but not the custom meta along with the revision.

16. Lester Chan,

    Thanks but how do I know if my posts have any custom meta data or not? E.g. what other data is being stored in the ofter tables?

    Thanks,

    Jimbo

17. There is no way of knowing unless you know the IDs of the post.

18. Thanks! Just what I have been looking for!

19. Dear Lester,

    THANK YOU VERY MUCH! I fullfill e-shop (of course without database backup on) and almost loose a 1 week work with “smart” revision function.

    THANK YOU AGAIN! Jurij Cvikl (Linkedln)

20. THANK YOU..I mean it..
    I just wonder why the wp core devs did not test this better. meta values are a core feature and the issue should have been plain to them before the release. Upgrading wp every heartbeat already is a pain (I have a heavily modified template and many customized features), but encountering these issues really makes me regret upgrading.
    Again, thank you

21. Hi mate,
    thanx for the explanation. It helped me a lot!

23. Wow very useful post. I was not even aware of the fact that post revisions are taking up huge db space. I iwsh we had a plugin for it rather than modify the config file which even though easy requires more manual work.

24. A lifesaver! My problem was a little more serious than most in that I’m using an ECOMMERCE plugin for my client’s site that kept on attaching itself to a revision of the main products page. This fixed it. Thanks for a very helpful post.

25. Nice plugin! Thank for sharing

27. Remember guys – you can do this with the newly updated for WordPress 2.7 WP-CMS Post Control plugin over at http://wordpress.org/extend/plugins/wp-cms-post-control/

    Whilst WordPress 2.7 gives some interface control to the write post and page panels, this plugin gives you COMPLETE control, also allowing you to turn off post revisions, auto save and even force the uploader back to the old browser one instead of Flash (this solves a-lot of problems for people).

    This update also covers all the new WordPress 2.7 interface features – for instance being able to hide the favorites dropdown in the header of the admin panel.

28. Thanks. Nice trick.

29. Thanks! This is really helpful.

30. Thanks…
