Version – PRC Platform

Get the latest version for various PRC_ constants.

Block Metadata

Property	Value
Name	`prc-block/version`
Category	`theme`
API	Version 3
Textdomain	`version`

Supports

This block defines no supports in its block.json. It does not register a traditional block type with register_block_type; instead, it registers a block bindings source and a block variation of core/paragraph.

Attributes

No block-level attributes. This is not a standalone block — it operates through block bindings on core/paragraph.

Block Bindings Source

The PHP class registers a block bindings source:

Property	Value
Source name	`prc-platform/version`
Label	`Version Info`

Supported Modules

The binding accepts a module argument in source_args:

Module	Output
`platform`	`Version: {PRC_PLATFORM_VERSION} "{PRC_PLATFORM_RELEASE_NAME}"`
`block-library`	`Version: {PRC_BLOCK_LIBRARY_VERSION}`
(default)	Falls back to `platform` output

The binding only works on core/paragraph blocks. Returns null for any other block type.

Block Variation

The index.js registers a core/paragraph variation:

Property	Value
Variation name	`version-info`
Title	`Version Info`
Placeholder	`Version: 1.2.0 "Spiteful Washington"`

The variation pre-configures metadata.bindings.content to use the prc-platform/version source with module: "platform".

Inner Blocks

None. This is not a container block.

Parent / Ancestor Requirements

None.

Available Styles

None.

Usage Instructions

Insert a Version Info block from the inserter (found under the core/paragraph variations).
The paragraph content is automatically bound to the prc-platform/version bindings source.
On the frontend, the paragraph will display the current platform version and release name (e.g., Version: 2.5.0 "Some Release Name").
To show the block library version instead, modify the binding's args.module to "block-library" in the block's advanced settings or code editor.
The block is editor-only in its script loading — it enqueues the editor script on enqueue_block_editor_assets to make the variation available in the inserter.

PHP Rendering

There is no custom render callback. The block relies on WordPress core's block bindings API:

Version::block_init() registers the bindings source prc-platform/version via register_block_bindings_source().
When WordPress renders a core/paragraph block with this binding, it calls get_version_info_for_block_binding().
The callback checks that the block is core/paragraph, reads the module source arg, and returns the appropriate version string.

Frontend Interactivity

None. The version string is rendered server-side as static text.

Block Markup Example

Saved markup (in post_content):

<!-- wp:paragraph {"metadata":{"bindings":{"content":{"source":"prc-platform/version","args":{"module":"platform"}}}}} -->
<p></p>
<!-- /wp:paragraph -->

Rendered output:

<p class="wp-block-paragraph">Version: 2.5.0 "Release Name"</p>

core/paragraph — The Version block is implemented as a variation of core/paragraph with block bindings.
