This seems like it has already been covered in the above comment.

## Description This PR fixes two issues with template lookup: ### 1. Templates with `index.html` block template fallback When using a theme that came with an `index.html` but not with a `front-page.html` block template, the site editor would show the following `Notice: Undefined index: front-page in /var/www/html/wp-content/plugins/gutenberg/lib/edit-site-page.php on line 162`. The reason is that I was setting the wrong key here: https://github.com/WordPress/gutenberg/blob/710373b254fbcd15d524afdeb31da0d93c4defd4/lib/edit-site-page.php#L158 This would use the name of the template that was _found_, not the name of the key that was looked for. So if we're looking up `front-page`, but don't find any template, and [thus fall](https://github.com/WordPress/gutenberg/blob/710373b254fbcd15d524afdeb31da0d93c4defd4/lib/template-loader.php#L226) back to `index`, the template will be stored under the `index` key, rather than the front-end one. The fix for this is to use the template we were looking for as key (rather than the name of the template we actually found). ### 2. Templates without `index.html` block template fallback When using a theme that doesn't come with any block templates at all, we need to provide a blank `index` template when the user first opens the site editor (see [discussion](#22893 (comment))).

Description
This PR fixes two issues with template lookup:
1. Templates with
index.htmlblock template fallbackWhen using a theme that came with an
index.htmlbut not with afront-page.htmlblock template, the site editor would show the followingNotice: Undefined index: front-page in /var/www/html/wp-content/plugins/gutenberg/lib/edit-site-page.php on line 162.The reason is that I was setting the wrong key here:
gutenberg/lib/edit-site-page.php
Line 158 in 710373b
This would use the name of the template that was found, not the name of the key that was looked for. So if we're looking up
front-page, but don't find any template, and thus fall back toindex, the template will be stored under theindexkey, rather than the front-end one.The fix for this is to use the template we were looking for as key (rather than the name of the template we actually found).
2. Templates without
index.htmlblock template fallbackWhen using a theme that doesn't come with any block templates at all, we need to provide a blank
indextemplate when the user first opens the site editor (see discussion).How has this been tested?
wp_templateCPTs (neither published norauto-drafts) from previous Site Editor runs. (It's best to start with a fresh install, i.e.npx wp-env clean all && npx wp-env start. Careful, this will wipe your WordPress install's data!)/wp-admin/admin.php?page=gutenberg-experimentsmust not be ticked. (Make sure the "Full Site Editing" checkbox is ticked -- since it also gets reset after a wipe.)theme-experimentsrepo (see thewp-envREADME).Open question
Upon running
I see a sleuth of
indextemplateauto-drafts. I was hoping that only one would be created 😕 -- maybe my newly added logic is still buggy.Types of changes
Bug fix. Fixes #22800.
