Description

This block works as a container for other pagination blocks that render links to navigate through the list of comments. It basically works the same as the Query Pagination block, but for comments.

It has the same settings:

  • changing layout and colors
  • choosing different styles for next/prev arrows.

Will close #35007
Is a follow-up of #36577

How has this been tested?

  1. Modify the Single Post template, adding a Comments Query Loop block
  2. Add inside the Comments Pagination block
  3. Check that the layout and color settings work (tested only in the editor)
  4. Check that the arrow setting works as expected (tested only in the editor)

Thanks @c4rl0sbr4v0 for taking care of this.

As I was the author of the original PR, I guess it wouldn't be OK to approve and merge my own PR 😅 , although from what @gziolo said in #36577 (comment) the PR should be ready to go.

As long as you both agree this PR is good to go it’s just a formality who clicks the approve button 😃

I plan to have a closer look at this PR on Monday but you don’t need to wait for me.

I created the PR, I cannot assign the review to me, neither merge 😆

I think the PR is good to go, after the merge, it will be updated once we merge and test the pagination links 😄

Great work. Let’s land it and iterate in the other open PRs that introduce all necessary inner blocks. I left some feedback to consider as we continue development. I haven’t tested this PR as it’s going to be heavily tested with further work.

Names of those blocks need to be updated later.

Sure! I guess the best way to address it is to do that in the PRs that implement the inner blocks.

That’s a bit surprising but I checked the history of the Query Pagination block and it looks like they had an issue with rendering of an empty div when there was no pagination to show. Basically it bails out early when inner blocks render nothing.

Where is it coming from? The class name isn’t prefixed with wp- so it raises a flag, but it might be as well some legacy name we need to maintain.

That CSS class is the same that the Query Pagination block has ― just changing query-pagination by comments-pagination (potential bad copy-paste? 👀 ).

By the way, I realized that the class name block-library-query-toolbar__popover is being used inside the QueryToolbar component (in the Query block), but the equivalent component for the Comments Query Loop block ― i.e. CommentsQueryLoopToolbar ― doesn't use any class.

I'm looking at whether it makes sense to add that style or not.

OK, after taking a deeper look I don't see any reason to keep that style.

In fact, it seems we could also safely remove the same code from the Query Pagination block as well, right? There is no element using that class (if I'm not mistaken).

That class actually looks like a copy of this one from the Query block, which styles the QueryToolbar component I mentioned previously.
