Quick note for those running WordPress 2.7, and are starting to freak out about the 500 gazillion revision rows that are now getting inserted into your database... There are a few ways to cull them - such as deleting all posts with type "revision", but that's pretty annoying. Thankfully, the WordPress docs now have a rough draft up on revision management which outlines some "hidden options".
The nicest is the WP_POST_REVISIONS setting you can add to your wp-config.php file. It accepts the following values:
- true (default), -1: store every revision
- false, 0: do not store any revisions (except the one autosave per post)
- (int) > 0: store that many revisions (+1 autosave) per post. Old revisions are automatically deleted.
So you can turn them off entirely by setting WP_POST_REVISIONS to false. I like to keep it enabled (it is useful when you just realised you did something stupid) but limit it to, say, 10 rows per post. Just open up wp-config.php in your text editor and add the line:
The next time you save a post, all the old revisions (besides the last 10) will be automatically deleted and your database will breathe a sigh of relief.
You can add the definition anywhere in the config file, but I put mine just before the comment:
/* That's all, stop editing! Happy blogging. */
That's all, stop editing! Happy blogging.
