Latest Posts block

Hi,
I found the file to edit:
In wordpress folder, wp-includes/blocks/latest-posts.php

I had success putting the post thumbnail but when I try to have the post excerpt, it shows the current page excerpt instead of the post’s.

I edited only a small part of the code (line 39):

		$list_items_markup .= sprintf(
			'<li>
			<a href="%2$s">%1$s%3$s</a><p>%4$s</p>',
			get_the_post_thumbnail( $post_id ),
			esc_url( get_permalink( $post_id ) ),
			esc_html( $title ), 
			get_the_excerpt( $post_id )
		);

Here is the complete code (edited by me):

<?php
/**
 * Server-side rendering of the <code>core/latest-posts</code> block.
 *
 * @package WordPress
 */

/**
 * Renders the <code>core/latest-posts</code> block on server.
 *
 * @param array $attributes The block attributes.
 *
 * @return string Returns the post content with latest posts added.
 */
function render_block_core_latest_posts( $attributes ) {
	$args = array(
		'numberposts' => $attributes['postsToShow'],
		'post_status' => 'publish',
		'order'       => $attributes['order'],
		'orderby'     => $attributes['orderBy'],
	);

	if ( isset( $attributes['categories'] ) ) {
		$args['category'] = $attributes['categories'];
	}

	$recent_posts = wp_get_recent_posts( $args );

	$list_items_markup = '';

	foreach ( $recent_posts as $post ) {
		$post_id = $post['ID'];

		$title = get_the_title( $post_id );
		if ( ! $title ) {
			$title = __( '(Untitled)' );
		}
				
		$list_items_markup .= sprintf(
			'<li>
			<a href="%2$s">%1$s%3$s</a><p>%4$s</p>',
			get_the_post_thumbnail( $post_id ),
			esc_url( get_permalink( $post_id ) ),
			esc_html( $title ), 
			get_the_excerpt( $post_id )
		);
				
		if ( isset( $attributes['displayPostDate'] ) && $attributes['displayPostDate'] ) {
			$list_items_markup .= sprintf(
				'<time datetime="%1$s" class="wp-block-latest-posts__post-date">%2$s</time>',
				esc_attr( get_the_date( 'c', $post_id ) ),
				esc_html( get_the_date( '', $post_id ) )
			);
		}
		$list_items_markup .= "</li>\n";
	}

	$class = 'wp-block-latest-posts';
	if ( isset( $attributes['align'] ) ) {
		$class .= ' align' . $attributes['align'];
	}

	if ( isset( $attributes['postLayout'] ) && 'grid' === $attributes['postLayout'] ) {
		$class .= ' is-grid';
	}

	if ( isset( $attributes['columns'] ) && 'grid' === $attributes['postLayout'] ) {
		$class .= ' columns-' . $attributes['columns'];
	}

	if ( isset( $attributes['displayPostDate'] ) && $attributes['displayPostDate'] ) {
		$class .= ' has-dates';
	}

	if ( isset( $attributes['className'] ) ) {
		$class .= ' ' . $attributes['className'];
	}

	$block_content = sprintf(
		'<ul class="%1$s">%2$s</ul>',
		esc_attr( $class ),
		$list_items_markup
	);

	return $block_content;
}

/**

function register_block_core_latest_posts() {
	register_block_type(

As I said, thumbnail is working well, so I don’t really get why the excerpt doesn’t.
Much appreciation to any help,
Florian

Hi,

Removing get_ from get_the_excerpt doesn’t change anything for me, it still displays the current page excerpt instead of the $post_id one.

I think it comes from the fact it doesn’t get $post_id as a valid argument, and the default value get_the_excerpt() and the_excerpt() are the global post (the current page/post).
My knowledges in PhP are not so good, which makes it hard for me to identify clearly the problem.

Hi,

I solved my problem using the following piece of code:

foreach ( $recent_posts as $post ) {
		$post_id = $post['ID'];

		$title = get_the_title( $post_id );
		if ( ! $title ) {
			$title = __( '(Untitled)' );
		}
		
		$post_url = get_permalink( $post_id );
		
		$text = get_post( $post_id );
		$text = $text->post_content;
		$text = wp_trim_words( $text, 25, '... <a href="'.$post_url.'">read&nbsp;more</a>' );
		$excerpt = $text;
				
		$list_items_markup .= sprintf(
			'<li>
			<a href="%2$s">%1$s%3$s</a><p>%4$s</p>',
			get_the_post_thumbnail( $post_id ),
			esc_url( get_permalink( $post_id ) ),
			esc_html( $title ), 
			$excerpt
		);

It shows the target post 25 first words and I put a link on the read more to access said post. It might not be the best way to do this but it works, which makes it the best way for me 😀

Hope it might help if someone has the same issue.
Have a nice day,
Florian

As it goes to wp-include, i don’t think you can include it to a theme or whatever.
My take on this at the moment is just to keep it in mind each time I have a wp update, which of course is not the best :/
