Post missing excerpt

[riaanlom]

If post doesn't have an excerpt, expected outcome is for it to be generated from the post content.

wp-includes/formatting.php
function wp_trim_excerpt line 3811

if ( '' === $text )

Previous versions of WP used == instead of === . The strict comparison operator returns an empty excerpt

Yes, I agree the == instead of === condition changed on the WordPress version 5.5

But are using like this?: ​https://developer.wordpress.org/reference/functions/wp_trim_excerpt/

Can you please review this one, May be it will help you.

Thanks,

I'm not calling the function directly.

This used to return the generate excerpt from the post content but with WP 5.5 it returns NULL

$post = get_post(1);
$excerpt = ! empty( $post->post_excerpt ) ? $post->post_excerpt : null;
$excerpt = apply_filters( 'get_the_excerpt', $excerpt, $post );

@riaanlom
Ok, I have one minor change.
Can you please try with below?

$post = get_post(1);
$excerpt = ! empty( $post->post_content ) ? $post->post_excerpt : null;
$excerpt = apply_filters( 'get_the_excerpt', $excerpt, $post );

Hope It will works for you.

Thanks,

Hi there, welcome to WordPress Trac! Thanks for the report.

This appears to be a regression in [47808].

The fix would probably be similar to [47580] / #49853.

[SergeyBiryukov]

In 48817:

Formatting: Make the check for empty text in wp_trim_excerpt() more resilient.

This addresses a regression in [47808], which caused excerpts to be generated from post content if an empty string is passed, but not for other values considered empty, e.g. null or false.

Props riaanlom, laxman-prajapati, SergeyBiryukov.
Fixes #51042.

Reopening for the 5.5 branch.

Merges [48817] to the 5.5 branch.
Fixes #51042.
