invalid permalink structure when %category% is in it

[universalone]

/%category%/%postname%/ as the permalink structure works and correctly outputs the URL, for example blogurl/category1/postx

BUT if one was to input blogurl/category999/postx into the addressbar, the same postx would show up even if it was NOT in category999, just in category1.

Confirmed in WP 3.0-alpha.

I thought this had been fixed in older versions.

What should be the functionality here, Canonical redirect, or a 404?

I'd be suggesting a redirect myself, as it matches the permalink structure, just wrong item within.

+1 on canonical redirect.

[universalone]

I agree with a canonical redirect with 301 moved permanently HTTP response.
But why did you assign it to 3.0? Can't it make it into a minor release?

IMO its not serious enough to go into a 2.9.x maintainence release. Its not stoping any functionality from working, and the link should never be generated by WordPress to start with. So i'd agree with the 3.0 milestone as long as someone patches it :)

I have trunk 12794 running at ​http://rfair.homelinux.com and I too am seeing this issue - see

+1 more for canonical

(In [13781]) Only allow %category% to be a valid category attached to the current post when using %category% in a permalink structure. Fixes #11807

(Sent it to the wrong ticket..)

13781 produces a warning when visiting a post within the "Uncategorized" category (possily others, haven't tested).

Specifically:

Warning: in_array() [function.in-array]: Wrong datatype for first argument in E:\wordpress-trunk\wp-includes\canonical.php on line 170

[dd32]

13781 produces a warning when visiting a post within the "Uncategorized" category (possily others, haven't tested).

I cant reproduce that myself, However, I'll add some defensive checks to the code just in case.

[dd32]

(In [13798]) Add some defensive checks to Canonical redirection of %category% to ensure notices are not thrown. Props jfarthing84 for pointing out possibility. See #11907

Seems that commit notice skiped the ticket.

Can you just check to see if the warnings are still present?

[jfarthing84]

I'm not seeing it anymore.
