[ISSUE] ACF Blocks - excerpt

[N04H]

Hello,
I have a problem with ACF. I created an ACF block that I complete in the posts. Unfortunately Wordpress and Rank Match not loading the ACF block content for the_excerpt() . Anyone have an idea why? Best regards and thank you for your answer

register block:

add_action('acf/init', 'my_acf_init_block_types');
function my_acf_init_block_types() {
    if( function_exists('acf_register_block_type') ) {
        acf_register_block_type(array(
            'name'              => 'przepis',
            'title'             => __('Przepis'),
            'description'       => __('A custom testimonial block.'),
            'render_template'   => 'template-parts/blocks/przepis.php',
            'category'          => 'formatting',
            'icon'              => 'admin-comments',
            'keywords'          => array( 'przepis' )
        ));
    }
}

block file:

<?php

/**
* przepis Block Template.
*
* @param   array $block The block settings and attributes.
* @param   string $content The block inner HTML (empty).
* @param   bool $is_preview True during AJAX preview.
* @param   (int|string) $post_id The post ID this block is saved to.
*/

// Create id attribute allowing for custom "anchor" value.
$id = 'przepis-' . $block['id'];
if( !empty($block['anchor']) ) {
    $id = $block['anchor'];
}
// Create class attribute allowing for custom "className" and "align" values.
$className = 'przepis';
if( !empty($block['className']) ) {
    $className .= ' ' . $block['className'];
}
if( !empty($block['align']) ) {
    $className .= ' align' . $block['align'];
}
// Load values and assign defaults.
$opis = get_field('opis') ?: '';
$skladniki = get_field('skladniki') ?: '';
$przygotowanie = get_field('przygotowanie') ?: '';
$porcje = get_field('porcje') ?: '';
?>

the_excerpt(); = NULL

Of course is the_excerpt empty. Since you seem to know a bit about coding, I suppose you know what the_excerpt is: a separate entry in the database for each post if it has any text. And you do that manually on each post.

Why do you think your ACF block would fill the_excerpt?

If you want to auto generate an excerpt from that ACF block, here's the solution:

Custom blocks inserted via Gutenberg editor returning JSON - ACF Support

1) I've created custom Gutenberg blocks using Advanced Custom Fields, using the acf_register_block() function. if ( function_exists( 'acf_register_block' ) ) { acf_register_block( array( 'name' => 'accordion-module', 'title' => 'Accordion Module', 'description' => 'Create a series of expandable...

Yes, I know, but in other posts wordpress automatically creates the_excerpt from the content, in this case it does not download the content of blocks from acf

A solution that I'm not proud of, but maybe someone will find it useful


function.php

function awp_get_excerpt($post=false) {
    if (!$post) {
        global $post;
    }
    if (!$post) { return ''; }
    $excerpt = '';
    $blocks = parse_blocks($post->post_content);
    if (count($blocks) == 1 && $blocks[0]['blockName'] == null) {  // Non-Gutenberg posts
        $excerpt = get_the_excerpt($post->ID);
    } else {
        foreach ($blocks as $block) {
            if ($block['blockName'] == 'acf/przepis') {
                $excerpt = $block['attrs']['data']['opis'];
                $excerpt = substr( $excerpt, 0, 260);
                $result = substr( $excerpt, 0, strrpos( $excerpt, ' ') );
                break;
            }
        }
    }
    return ( $result ? strip_tags( $result ).'...' : '' );
}

remove_filter( 'get_the_excerpt', 'wp_trim_excerpt', 10, 2 );
add_filter( 'get_the_excerpt', function ( $excerpt, $post ) {
    if ('przepisy' == get_post_type() ){
    return awp_get_excerpt($post);
}
return $excerpt;
}, 10, 2 );

add_action( 'rank_math/frontend/description', function( $description ) {
    global $post;
    $desc = RankMath\Post::get_meta( 'description', $post->ID );
 
    if (is_single() && 'przepisy' == get_post_type() ){
        $description = $desc." ".awp_get_excerpt($post);
    }
    return $description;
});
