parent block - Add a block called parent block

[bobbingwide]

Where the children-block shows the children of the current page the parent block will create a link to the parent of the current page. It's a one level breadcrumb.

Block name: oik/parent-block Source: src/parent-block

Creation method:

• Copy and cobble the children-block having completed #2.
• Change the server side rendering logic.
• See what happens with index.asset.php.

I don't know what to do with block.json.

I don't know what to do with block.json.

In WP Block Builder, which delivers two starter blocks, there's a block.json in each of the blocks source files directory - under src/blocks/block-name.

So that's probably how to do it. Though I still don't know how code is expected to use this file. None of the existing routines seem to reference it. Does Gutenberg do this automagically?

Having read https://wptavern.com/revised-block-directory-guidelines-proposal-updates-wording-but-changes-little-else I'm tempted to extend the parent block to make it implement a full breadcrumb. It's not rocket science and it should pass guideline 7. Server-side code should be kept to a minimum.

There are limits to the REST API, and situations where server-side PHP is the only performant way to implement a feature. In those situations, PHP code may be included, provided it is clearly written, used as little as possible, and well documented.

But it would need to be a separate plugin, probably called breadcrumbs.

See #4 - the parent block should be moved to a separate Single Block plugin called sb-parent-block.
