post-content like post-excerpt and vice-versa?

[bobbingwide]

Interestingly the post-excerpt block appeared more like the post-content block and vice-versa.

Well, the post-content block appeared more like an excerpt than post content.
In order to fix this I had to change the core function get_the_content() to set $elements['more'] to true, since generate_postdata() hadn't.

Not surprisingly this didn't resolve the problem with the post-excerpt ignoring the more block.

Problem

core/post-content when nested in a query in another post's query-loop's core/post-content block is broken by a more block.

While developing my fix for the post-content infinite recursion problem, I became aware of a problem with the display of post content in the nested posts. The workaround I implemented for #27 was to eliminate the more block from the content that was being displayed.

In the above screen capture I've re-introduced the core/more block into the Aab page.
The post content should be 'Aab - excerpt before more. Aab - post content after more.'
The More link shouldn't appear.

While trying to create a simple test for the problem I accidentally moved a block from a dynamically displayed post out of the Post content block. This shouldn't be possible. Here the WordPress block came from the post entitled WordPress.
I was trying to move the Post content block into the first column.

Here's the result where page Aaf uses a query to display the last post in two columns with Post content on the left and Post excerpt on the right. The Post content looks more like that which I'd expect the Post excerpt should look.
The Post excerpt should display the more link.

In the block editor the display is more confusing.

The content of page Aaf is

<!-- wp:paragraph -->
<p>aaf's post excerpt before more.</p>
<!-- /wp:paragraph -->

<!-- wp:query {"queryId":1,"query":{"perPage":1,"pages":1,"offset":0,"postType":"post","categoryIds":[],"tagIds":[],"order":"desc","orderBy":"title","author":"","search":"","exclude":[1346],"sticky":""},"className":"border"} -->
<!-- wp:query-loop -->
<!-- wp:post-title {"isLink":true} /-->

<!-- wp:columns -->
<div class="wp-block-columns"><!-- wp:column -->
<div class="wp-block-column"><!-- wp:heading {"level":3} -->
<h3>Post content</h3>
<!-- /wp:heading -->

<!-- wp:post-content /--></div>
<!-- /wp:column -->

<!-- wp:column -->
<div class="wp-block-column"><!-- wp:heading {"level":3} -->
<h3>Post excerpt</h3>
<!-- /wp:heading -->

<!-- wp:post-excerpt {"wordCount":43,"showMoreOnNewLine":false} /--></div>
<!-- /wp:column --></div>
<!-- /wp:columns -->
<!-- /wp:query-loop -->
<!-- /wp:query -->

<!-- wp:more -->
<!--more-->
<!-- /wp:more -->

<!-- wp:paragraph -->
<p>aaf's post content after more.</p>
<!-- /wp:paragraph -->

The content of the post with the highest title ( Zzz ) is

<!-- wp:paragraph -->
<p>Zzz - post excerpt before more.</p>
<!-- /wp:paragraph -->

<!-- wp:separator -->
<hr class="wp-block-separator"/>
<!-- /wp:separator -->

<!-- wp:more -->
<!--more-->
<!-- /wp:more -->

<!-- wp:paragraph -->
<p>Zzz - start of post content after more. </p>
<!-- /wp:paragraph -->

Expected result - front end

Expected result - editor

Post content

The More block should not be a problem

Post excerpt

Should be processed the same as on the front end.
That may involve:

• using the post_excerpt field, if set

or

• expanding shortcodes
• stopping at the more tag
• NOT stripping HTML tags
• displaying the more link as specified in the block

[bobbingwide]

I've been retesting this using the original data for #27 and I'm still getting strange results.

The content of post B is

<!-- wp:paragraph -->
<p>B's normal excerpt</p>
<!-- /wp:paragraph -->

<!-- wp:more -->
<!--more-->
<!-- /wp:more -->

<!-- wp:paragraph -->
<p> [bw_wpadmin]</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>B's normal content</p>
<!-- /wp:paragraph -->

When displaying the post excerpt for B I'd expect to see "B's normal excerpt"
For the post content I'd expect to see all of the above.

What I'm actually getting is just the post content, there's no post excerpt.

<div class="entry-content wp-block-post-content is-layout-flow">
<p>B’s normal excerpt</p>
<p> <a href="https://s.b/wp55/tt1/b/#more-92" class="more-link"><span aria-label="Continue reading B">(more…)</span></a></p>
</div>

Perhaps it's my understanding of what the more block is supposed to do!
When there isn't a more block it seems OK.
I'll have to check the query loop again.

I'll have to check the query loop again.

OK, the reason we don't see post excerpt is because it's not included in the post-template.

I should be attempting to reproduce the problem with page Aaf and post Zzz.
... and then understand / believe that what I got told in Nov 2020 is that what I'm seeing is what was intended!

Environment now is s.b/wp URL: https://s.b/wp/aaf/

• When there isn't a more block in Zzz then the post content and post excerpt are displayed the same on the front end.

• When there's a hand cranked excerpt then we see the hand cranked excerpt.

• When there's a more block then the post content is truncated at the more.

• When the more block "Hide the excerpt on the full content page" is toggled on then

  • the post content in the query loop shows the excerpt
  • the content before the more is not displayed when when viewing the post

These were the results testing with WordPress 6.0.1 and Gutenberg 12.3.0
I'd better repeat the tests with the latest versions: WordPress 6.2-RC1 and Gutenberg 15.3.1

[bobbingwide]

With WordPress 6.2-RC1 and Gutenberg 15.3.1 the results are different.

• DIFFERENT When there isn't a more block in Zzz then the post content and post excerpt contain the same data but the excerpt has lost all the HTML formatting.
  

• SAME When there's a hand cranked excerpt we see the hand cranked excerpt

• SAME When there's a more block then the post content is truncated at the more. See the first screen capture in post-content like post-excerpt and vice-versa? #43 (comment)

• When the more block "Hide the excerpt on the full content page" is toggled on then

  • SAME the post content in the query loop shows the excerpt
  • SAME the content before the more is not displayed when when viewing the post

The Expected result - front end that I documented on 23 Nov 2020 at 10:54 pm reflects the results I used to get using the [bw_pages] shortcode displaying post_content (C) or post_excerpt (E).

#43 (comment)

[bobbingwide]

I've reproduced the Expected result - front end with the page Aaf 2023.
This page uses the [bw_field] shortcode to display post_content and post_excerpt directly from the post's fields. These have the green background. Below these are the output of the blocks.

Note that what's displayed for the post content block is different in the editor.

What I see in the editor is what I want in the front end!

I suppose I could override the behaviour of the post-content and post-excerpt blocks to achieve this. I won't close this issue yet.
