With permalink structure /%postname%/%monthnum%/

When I visit a post in frontend it throw me a notice

Nice cache @1naveengiri

Confirm if we use /%postname%/%monthnum%/ in Custom Structure then in front end it show attached Notice: Undefined index: year in /mukesh/wordpress5.0/wp-includes/rewrite.php on line 387

Error when we check frontend.

Please try this patch it working fine for me.

This will need fairly careful testing and review for back compat issues.

Unit tests would be useful here.

Hi Guys,

Just a friendly follow-up,

Thanks

In 53861:

Tests: Improve the test for not throwing a warning on malformed date queries.

• Make it specifically about wp_resolve_numeric_slug_conflicts(), the function that was throwing an Undefined array key "year" PHP warning for malformed date requests.
• Move the test under the rewrite component and make its name a bit more descriptive.
• Check the return result of the function instead of performing a dummy assertion.
• Use named array keys in the data provider for clarity.
• Add missing @covers tag.

Follow-up to [32648], [53857].

Hi there, thanks for the ticket and the patch! Sorry it took so long for someone to get back to you.

I believe this is fixed in [53857] and [53861]. The props from this ticket are included in the latter commit.
