Fast follow: Redirections of deprecated site editor URLs.

[peterwilsoncc]

What?

Follow up to #67199
Incorporating changes in WordPress/wordpress-develop#7903
See https://core.trac.wordpress.org/ticket/62585
See #67199

• Adds docblock to gutenberg_get_site_editor_redirection()
• Uses wp_safe_redirect()
• Uses temporary redirect instead of a 301

Why?

Bringing suggested changes from WordPress/wordpress-develop#7903 to the plugin

• Docblocks are good
• For redirects within WP it's best to use safe redirects to validate the destination
• Logged in and logged out users will be redirected to different locations, so 302 redirects are needed to ensure the browser doesn't cache an incorrect destination

How?

As above.

Testing Instructions

1. Log in to WP
2. Visit a deprecated site editor URL
3. Ensure it redirects to the expected location
4. [Repeat for multiple deprecated URLs]
5. Log out of WP
6. Visit a deprecated site editor URL
7. Ensure it redirects to the login screen rather than the new URL

If you've tested the redirection of site editor URLs in the past, your browser may have the permanent redirects cached. If that is the case, you will need to test in a browser you don't usually use.
