One can control the WP default (Automatic) excerpt length of a WP post using the using the following snippet within functions.php;
From the WP Codex
// . Post excerpt adjustment (Auto)
// . ==============================
function wpdocs_custom_excerpt_length( $length ) {
return 20;
}
add_filter( 'excerpt_length', 'wpdocs_custom_excerpt_length', 999 );
My question is how do you limit the manual one?
You know, the exerpt specifically added by the user themselves?
(*) There is an 8 year old question here, that does provide some context but given the current year and progress WP has made I want to post the question again and receive some clarity on the subject.
Added Context: (Edited: 12 March 2019)
It's not that the original answer to the question posted earlier doesn't work, all be it seems, really clunky. I'm looking for a more simple & robust answer using exerpt_length filter. Rather than using something like the following to trim the text; (If Possible)
function excerpt($limit) {
return wp_trim_words(get_the_excerpt(), $limit);
}
We have by default in core, the following filtering:
add_filter( 'get_the_excerpt', 'wp_trim_excerpt' );
but within wp_trim_excerpt() the trimming is only applied on the post's content, when there's no manual excerpt set.
Here's an untested suggestion for a custom filtering:
add_filter( 'get_the_excerpt', function( $excerpt, $post ) {
if ( has_excerpt( $post ) ) {
$excerpt_length = apply_filters( 'excerpt_length', 55 );
$excerpt_more = apply_filters( 'excerpt_more', ' ' . '[…]' );
$excerpt = wp_trim_words( $excerpt, $excerpt_length, $excerpt_more );
}
return $excerpt;
}, 10, 2 );
to apply the similar trimming on manual excerpts.
Hope you can adjust this further to your needs.
Try this, I got this code from here: https://www.wpexplorer.com/wordpress-excerpt-length/
add_filter( 'excerpt_length', function($length) {
return 20;
} );
This pair of functions will give you control over the excerpt length, including the manual excerpt which is returned if available, otherwise the "excerpt-ized" post_content gets returned. These go in your theme functions file:
function get_excerpt_by_id($post_id, $length = NULL) {
$length = isset($length) ? $length : apply_filters('excerpt_length', 32);
$p = get_post($post_id);
return $p->post_excerpt ? build_excerpt_by_length($p->post_excerpt, $length) : build_excerpt_by_length($p->post_content, $length);
}
function build_excerpt_by_length($content, $length = 32) {
$excerpt = strip_tags(strip_shortcodes($content));
$words = explode(' ', $excerpt, $length + 1);
$words = array_slice($words, 0, $length);
$result = trim(implode(' ', $words));
$result = preg_replace('/\W*$/', '', $result);
$more = apply_filters('excerpt_more', '…');
if ($result !== '') $result = $content === $result ? $result : $result . $more;
return $result;
}
Then in your templates you can use by calling:
get_excerpt_by_id($your_post_id, $preferred_excerpt_length);
You can try the following code
$excerpt = get_the_excerpt();
$excerpt = substr( $excerpt, 0, 180 );
$excerpt_description = substr( $excerpt, 0, strrpos( $excerpt, ' ' ) );
echo $excerpt_description;

I don't understand why function below influence woocommerce_taxonomy_archive_description()
Where is connection between those two? Shouldn't this work only for woocommerce_short_description?
add_filter( 'woocommerce_short_description', 'limit_woocommerce_short_description' );
function limit_woocommerce_short_description( $post_post_excerpt ) {
if(!is_product()) { // add in conditionals
$text = $post_post_excerpt;
$words = 24; // change word length
$more = ' […]'; // add a more cta
$post_post_excerpt = wp_trim_words( $text, $words, $more );
}
return $post_post_excerpt;
}
I have found the following code from this answer thread, but it only applied under the product title. So how can apply to the detailed description of the product.
add_action( 'woocommerce_after_shop_loop_item_title', 'shorten_product_excerpt', 35 );
function shorten_product_excerpt()
{
global $post;
$limit = 14;
$text = $post->post_excerpt;
if (str_word_count($text, 0) > $limit) {
$arr = str_word_count($text, 2);
$pos = array_keys($arr);
$text = substr($text, 0, $pos[$limit]) . '...';
// $text = force_balance_tags($text); // may be you dont need this…
}
echo '<span class="excerpt"><p>' . $text . '</p></span>';
}
In Woocommerce product single pages, the long description is displayed in the "description tab". If you look at the source code of single-product/tabs/description.php template, it use the_content() wordpress function to display that long description.
So you can use the_content dedicated Wordpress filter hook to reduce the product long description:
add_filter( 'the_content', 'shorten_product_long_descrition', 20 );
function shorten_product_long_descrition( $content ){
// Only for single product pages
if( ! is_product() ) return $content;
// Set the limit of words
$limit = 14;
if (str_word_count($content, 0) > $limit) {
$arr = str_word_count($content, 2);
$pos = array_keys($arr);
$text = '<p>' . substr($content, 0, $pos[$limit]) . '...</p>';
$content = force_balance_tags($text); // needded
}
return $content;
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.

I have a problem with getting the first form the_excerpt();
Function acutally works but only for first post. I added in functions.php
function get_first_paragraph(){
global $post;
$str = wpautop( get_the_content() );
$str = substr( $str, 0, strpos( $str, '</p>' ) + 4 );
$str = strip_tags($str, '<a><strong><em>');
return '<p>' . $str . '</p>';
}
I'm calling this funcion in index.php inside The Loop <?php echo get_first_paragraph(); ?>
I have no idea why it pulls only for first post...
you can put this code in function.php file in your theme,
Get first paragraph
function awesome_excerpt($text, $raw_excerpt) {
if( ! $raw_excerpt ) {
$content = apply_filters( 'the_content', get_the_content() );
$text = substr( $content, 0, strpos( $content, '</p>' ) + 4 );
}
return $text;
}
add_filter( 'wp_trim_excerpt', 'awesome_excerpt', 10, 2 );
For more information, you can follow the reference link WORDPRESS THE_EXCERPT SHOW ONLY FIRST PARAGRAPH
That code didn't work for me in Gutenberg times. So I've used part of that code and did some searching and come up with this solution. Hope it helps.
function get_paragraph_content($paragraph_number){
global $post;
$i = 0;
$paragraph = '';
if ( has_blocks( $post->post_content ) ) {
$blocks = parse_blocks( $post->post_content );
foreach( $blocks as $block ) {
if( 'core/paragraph' === $block['blockName']){
$paragraph = render_block($block);
if (++$i == $paragraph_number) break;
}
}
$paragraph = substr( $paragraph, 0, strpos( $paragraph, '</p>' ) + 4 );
$paragraph = strip_tags($paragraph, '<a><strong><em>');
}
return $paragraph;
}
I'm currently pulling in multiple pieces of content into my posts through an AFC with the value: "section_content". Furthermore, I'm using the code below to clean up my WP posts. How would I modify this filter to also include my ACF?
<?php
/**
* Clean posts from inline styling and unnecessary tags
*/
add_filter( 'the_content', 'clean_post_content' );
function clean_post_content($content) {
if ( is_single() ) {
$patterns = array(
'/(<[^>]+) style=".*?"/i', // Remove inline styling
'/<\/?font[^>]*>/', // Remove font tag
'/<(p|span)>(?>\s+| |(?R))*<\/\1>/', // Empty p, span (font tags already removed)
'/(<h[1-6]>[^<]*)<\/?strong>(.*?<\/h[1-6]>)/', // h1-6
);
$replacements = array(
'$1',
'',
'',
'$1$2'
);
$old_content = '';
while ($old_content != $content) {
$old_content = $content;
$content = preg_replace($patterns, $replacements, $content);
}
}
return $content;
}
?>
I guess you could use ACF Filters. I usually hook to acf/format_value in order to clean or modify my custom field values before printing them.
You can even hook to certain field types only, like:
function acf_brand_trademark( $value, $post_id, $field ) {
$value = preg_replace( '/Brand /', 'Brand<sup>™</sup> ', $value );
return $value;
}
add_filter('acf/format_value/type=textarea', 'acf_brand_trademark', 10, 3);
add_filter('acf/format_value/type=text', 'acf_brand_trademark', 10, 3);
Hope this helps!
At the moment i have a function and a filter which shortens titles if they are longer than 25characters and appends the triple dot '...'
However, it appends the dots to all the titles. How can i get the following code to run only if the title is longer than 25 characters?
function japanworm_shorten_title( $title ) {
$newTitle = substr( $title, 0, 25 ); // Only take the first 25 characters
return $newTitle . " …"; // Append the elipsis to the text (...)
}
add_filter( 'the_title', 'japanworm_shorten_title', 10, 1 );
You can use PHP's strlen: http://php.net/manual/en/function.strlen.php
Your code would go like:
function japanworm_shorten_title( $title ) {
if (strlen($title) > 25){
$title = substr( $title, 0, 25 ).'…';
}
return $title;
}
add_filter( 'the_title', 'japanworm_shorten_title', 10, 1 );
