Description

Adds a container block in which you can place any other blocks, that are displayed when the query (loop) has no results.

See #36609, #27302

This is a simplified version that:

  • Does not make any changes to the post template which already displays a "no results" message in the editor but not the front.
  • Does not implement the suggestion to have a setting in the query block that opens a modal with editable content.
  • Does not output a default message.

Alternative: #36225

Challenges:
How to explain how the block can be used in the query loop.
Test the many different scenarios (for example, if the query is set to only include sticky posts, and the install has no sticky posts, both the non-sticky posts and the "no results" message is shown, and this is a bug).

Testing Instructions

  1. Apply the PR
  2. Activate a theme with support for the site editor
  3. Trash all posts on your test install
  4. In the site editor, add a query block to the home or index template (depending on what shows the blog in your active theme)
  5. Add a "no results" block inside the query.
  6. Add some blocks inside the no results block.
  7. Save and confirm that the inner blocks are displaying correctly on the front.

This PR looks sane enough to me but would be nice to create some type of custom message in the Block. Something like this?

"No Results Block
Add child Blocks that will display when query returns no results."

Could you use wordpress/components Placeholder for this?

#38366

After this accessibility fix was merged, I wonder if this would at least be better than nothing for now.

https://github.com/WordPress/gutenberg/tree/trunk/packages/components/src/placeholder

Just a thought...

I experimented a bit with the placeholder component but I was not able to combine it with an inserter.
I also thought about the type of placeholder that is used in the columns block, where you select a variation to add inner blocks to the container.

I think that displaying a default text that the user can update is the easiest alternative to start with.

I think that displaying a default text that the user can update is the easiest alternative to start with.

Makes sense to me... If someone wants to change the message and/or add extra blocks etc, all they have to do is click on it in the editor and they'll be able to change it.
If they never change it, then it's safe to assume that it's OK, so a default "No results found" message in the content would be the simplest approach for now.

I went ahead and rebased the PR to bring it up to speed 👍

Overall the code makes sense. Tested and does what is expected 👍

Some notes:

  • We should write a better description for the block
  • I believe it would be best to add this block to the default template for the query. If users don't want it and it's there they can remove it, but if they want it and it's not there, looking for it and manually adding it will be harder (and will probably look like a bug to a lot of people)

The code is clean and looks good.
Does what it's supposed to do.
Doesn't introduce any backward-compatibility issues for existing instances, has a placeholder which is explanatory and allows users to add what they want.

Overall this looks good to me and fixes the issue.

Great work @carolinan!

I have to spend a few seconds re-reading this description in order to understand what I need to do, so IMO it's sub-optimal.
However, it is consistent with the comment-template and post-template blocks which use similar wording, so if this changes it would ideally also change in other blocks as well - so not something specific to this PR.

I think "Contains the content shown when no query results are found" would convey the same meaning in fewer words. Maybe even just "The content shown when no query results are found" would work.

I like the first suggestion, but I would like the related block descriptions to have a "simpler" language, and not only this new block.
