Query Loop: Remove is_singular() check and fix test #65483

What?

This is a follow-up to #65067 to improve the implementation of querying 'post' post types.

Why?

As inherit is now automatically set to false when a Query Loop is inserted within content (a single post/page/CPT), we don't need to manually update the query in an is_singular() check.

Also, query_posts() should generally be avoided as it could cause some unwanted side effects. See this comment for more details.

How?

Removes the is_singular() check from the Post Template server-side render, and updates the test_rendering_post_template_with_main_query_loop_already_started test so that it is correctly using inherit: false in the test block markup.

Testing Instructions

  1. Insert a query loop block in a singular page/post/CPT
  2. Ensure that it defaults to displaying posts in both the Editor and front-end
  3. Ensure that the post type can be changed in the Editor and, if customised, that it shows the custom query on the front-end
  4. Ensure the test_rendering_post_template_with_main_query_loop_already_started PHP unit test passes

The change makes sense to me and still works as described in the original PR. I just have a question about the test.

Why does this test need to change? Was this not testing with the correct inherit setting before?

Was this not testing with the correct inherit setting before?

No 🙈 And it was passing because I was using query_posts(), which I think was replacing the global query, so anything set via the Query Loop block was ignored and wasn't truly being tested.

This test should have been updated when the changes were added for automatically setting inherit to false in the original PR. It was a complete oversight by me, although I'm glad I updated the test earlier on in the process and so I knew how to fix it. 😅

Thanks for taking a look, @jffng! With @dlh01's help, I noticed that we no longer need the is_singular() check in the server-side rendering of the Post Template. It looks like setting inherit to false when within singular content was the only change needed.

I've updated the PR to include this change, and we also need the fix for the test so it's testing with the correct markup (inherit: false).

This is ready for another review 🙏
