"Redirect Old Slugs" should be in core.

Simply, this should be in core, there's no reason why any WP installation should be without this.

You're just saying that because I have commit access. :-P

Okay, I can't lie. It's a brilliant plugin, and you're right.

Patch for /trunk/

[markjaquith]

Patch is up.

• New meta key (_wp_old_slug) which will be hidden (it should just WORK without people even seeing it)
• People who were using the plugin will have their old slugs updated to the new meta key on upgrade
• uses wp_redirect($link, '301') now
• Only works on posts. There doesn't seem to be a clean way of recognizing failed Page attempts... of course there is always my "Page Links To" plugin to take care of that. ;-)
• Works completely through filters.

I'm obviously biased, so I'm going to need some +1's here

Gets my vote. Helps the noobs and people like me who can't spell. :)

[bryanveloso]

Yea, why isn't that one in core either? :P

[matt]

+1, go for it.

If you're going to commit this, can you also make the slug automatically update to reflect the post title when the post title is changed? I believe the reason the slug wasn't updated to reflect an updated post title was to not break links, but if this is committed, that won't be an issue.

JeremyVisser,

Hm, probably not a great idea. It'd cause a lot of unnecessary redirects. Take for instance the rather common practice of updating "Post Title" to "Post Title (UPDATED!)" ... that shouldn't cause a slug change, because, well, it doesn't make sense to have "updated" in the slug, it'll break caching, and it could cause the link to lose a bit of Google juice.

(In [4556]) Remember old post slugs and automatically redirect to the new slug. fixes #3202

I see this when updating the slug on a published post.

(In [4571]) cast to array when checking for old post slugs. fixes #3202
