What?

  • Added default avatar fallback support to Post Author Block in editor
  • Moved useDefaultAvatar hook to shared utils location for code reusability
  • Fixed avatar placeholder display when Post Author Block is used outside postId context

Why?

  • Post Author Block avatar wasn't showing placeholder in editor when inserted outside postId context (e.g., in single post templates)
  • Avatar Block already had proper fallback mechanism showing placeholder correctly
  • Code duplication existed with useDefaultAvatar logic in Avatar block but not shared

Fixes / Reference
Fixes #71715

How to test:

  1. Open Site Editor and navigate to Single Posts template
  2. Insert the following HTML into the template:
<!-- wp:group {"layout":{"type":"constrained"}} -->
<div class="wp-block-group">
	<!-- wp:post-author {"showAvatar":false} /-->

	<!-- wp:avatar /-->
</div>
<!-- /wp:group -->
  1. Verify that both Avatar and Post Author blocks now show avatar placeholders in the editor
  2. Confirm that Post Author Block avatar setting is enabled and placeholder appears

Files changed:

  • packages/block-library/src/post-author/edit.js - Added useDefaultAvatar import and fallback logic
  • packages/block-library/src/utils/hooks.js - Added shared useDefaultAvatar hook
  • packages/block-library/src/avatar/hooks.js - Refactored to use shared useDefaultAvatar hook
