Description

Fixes #32960.
Requires WordPress/wordpress-develop#1433.

Addresses a few different bugs affecting non-WP_Widget widgets, like the Marquee Greeting widget.

It's still altogether really awkward (e.g. if you add two non-WP_Widget widgets then only one will be saved, and if you delete a non-WP_Widget widget then it will move to Inactive Widgets after a refresh) but this is a rare type of widget and it's better than what's in trunk.

  • Fixes 'record is undefined' error when saving a non-WP_Widget widget.
  • Fixes Legacy Widget block's form refreshing while you type in the input field of a non-WP_Widget widget.
  • Fixes the Legacy Widget block so that it always shows the form for non-WP_Widget widgets. (These kinds of widgets don't support previewing.)

How has this been tested?

  1. Check out Widgets REST API: Make non-multi widgets appear in wp_inactive_widgets wordpress-develop#1433.
  2. Add the marquee widget to your WP installation
  3. Go to the widgets editor and add marquee.
  4. Try to save the form.

I'd like to add a regression E2E test here since it's very prone to breaking. Will hopefully have some time to do so on Monday.

@noisysocks it works really well (aside of a small delay between adding the legacy widget and the form showing up – we can live with that). I added regression tests and updated the other E2E tests to hopefully pass. It's all green on my localhost when https://github.com/WordPress/wordpress-develop/pull/1433/files is applied. Unfortunately, TravisCI checks won't pass until the backend PR is merged. I am approving this in advance anyway so that we have a path forward.

Thanks @adamziel. I committed WordPress/wordpress-develop#1433 so hopefully E2E tests pass if I restart them.

I don't know how to force GitHub Actions to check out the latest copy of WordPress. I'll merge this and split the E2E tests you added into a follow-up PR.

edit: Nope, turns out the update to core causes failures in Gutenberg trunk anyway.

I guess we can use class names to select the inputs rather than using duplicate ids, since that we control the test plugin.

waitFor is meant for more advanced usage at the time, I think we can simply use page.waitForFunction here.

Is it intentional that we type Howdy above but showing Hello! here in the snapshot?

I guess we need more comments here as it's really counter-intuitive 😅 .

We just need a note to say that we're asserting that the second instance of a function based widget is not persisted. We should also note why that's important with references to documentation or technical details.

Nice work debugging and solving this one 🙌

Left some nits around comments and context. I do feel this is a reasonably obscure area of widgets so it would be good to codify the knowledge you've gained and leave it within the code to help future devs.

Is this test about the implementation of the marquee widget specifically? I'm not sure it is.

Therefore, I wonder whether we ought to rename this test to be more descriptive about the feature actually under test here?

// Add another marquee

Nit: this bit doesn't perform any assertions on whether it's saved. As a result, this comment confused me slightly.

What are we throwing for here? It would be great if we could convert marquees.length into a well-named variable so the test code is self-descriptive.

waitFor expects the underlying async callback to throw if there are no results so that it could automatically retry. But as I said above, might be easier to use page.waitForFunction here.

Do we want to provide an error message to help future debugging efforts?

This bit is asserting on the rendered output. So double checking that the 2nd instance wasn't saved or rendered back to the editor on page reload.

Is "multi" and "non-multi" a recognised technical term? If not then we should probably add additional context here.

This feels like it needs a comment with context to explain why idBase is a determining factor in selecting the "mode".
