Page auto-draft & guid generation

[shawnparker]

Guid generation for pages is currently broken. auto-draft status is currently not handled and all page guids are simply the base site_url instead of site_url + ?page_id=000.

I looks as if auto-drafts were handled for posts here: http://core.trac.wordpress.org/changeset/14948

Attached is a patch for the _get_page_link() function in wp-includes/link-template.php to account for a post_status of auto-draft and properly generate the guid for pages (patch is to 3.0.1 tag, but issue exists in the same function in 3.0 branch and trunk as well).

REVISED auto draft fix for pages

The change that patch wants to make to line 283 needs modification. I took that from the post permalink function and forgot to change $post_link to $link.

Punting all tickets that are not regressions in 3.1.

Per IRC. This is a nasty bug for anyone using feeds in any regard for pages. Rare, but I'm sure someone does, perhaps for child pages or something.

Might we need to run an upgrade script to update old page GUIDs, too?

(In [17061]) Fix guid generation for page auto drafts. Props shawnparker. fixes #15041

For [17061]: The check for

isset($post->post_status)

in line 192 comes after $post->post_status has already been used to create $draft_or_pending in line 188, which is to late to avaid notices.

Thus, the check should be part of the $draft_or_pending conditional in line 188.

Moved the check to the proper place

Added new patch.

(In [17076]) Relocate isset check. Props TobiasBg, SergeyBiryukov. fixes #15041

Great catch
