Author Name / Author Bio / Avatar: Not displayed in author archive template

[t-hamano]

Description

@them-es reported this problem in this comment.

When the following three blocks are inserted into the author archive template, the information is not displayed correctly on the front end.

• Avatar
• Author Name
• Author Biography

On the other hand, the Post Author block displays the correct information. This is probably because it uses the author query parameter when no post context exists.

I think similar fallbacks are needed for these three blocks as well:

gutenberg/packages/block-library/src/post-author/index.php

Lines 17 to 21 in 017d1ad

	if ( ! isset( $block->context['postId'] ) ) {
	$author_id = get_query_var( 'author' );
	} else {
	$author_id = get_post_field( 'post_author', $block->context['postId'] );
	}

Step-by-step reproduction instructions

• Add Author Archive template.
• Enter the following code in the template's code editor and save it.

  <!-- wp:post-author {"showBio":true} /-->
  <!-- wp:post-author-name /-->
  <!-- wp:post-author-biography /-->
  <!-- wp:avatar /-->
  

• Create a user with the bio. Please note your user ID.
• Access http://localhost:8888/?author={user_id}.
• The three blocks listed above should not display author information.
• At the same time, you should see the following error:

  Warning: Undefined array key "postId" in /var/www/html/wp-content/plugins/gutenberg/build/block-library/blocks/avatar.php on line 34
