The tutorial is not working anymore. The link is broken. Any advice?

@naturetti

// truncate Yoast SEO breadcrumb title
add_filter('wp_seo_get_bc_title', function($link_text, $id) {
  if ( strlen( $link_text ) <= ($limit = 20) ) return $link_text;
  return substr( $link_text, 0, $limit ).'&hellip;';
}, 10, 2);

A new warning shows up:
Notice: wp_seo_get_bc_title is deprecated since version WPSEO 5.8! Use wpseo_breadcrumb_single_link_info instead. in /home/username/public_html/wp-includes/functions.php on line 4089

is there anyone who can help? Thank you :)

@GermontZ

using the new filter will look something like this (I have changed it slightly from the example above)

function shorten_yoast_breadcrumb_title($link_info)
{
    $limit = 20;
    if (strlen($link_info['text']) > ($limit)) {
        $link_info['text'] = substr($link_info['text'], 0, $limit) . '…';
    }

    return $link_info;
}

add_filter('wpseo_breadcrumb_single_link_info', 'shorten_yoast_breadcrumb_title', 10);

Hi,
can it also be done with yoast meta title?

@lealustore There's nothing impossible when it comes to coding... 😉😉😉

Here's the function to truncate Yoast Meta Title:

function limit_title_yoast( $str ) {
 return substr($str, 0, 65); //Replace number 65 with your desired character
}
add_filter( 'wpseo_title', 'limit_title_yoast' );

@robinurislamsohan
good, if i want to limit only post title variable on meta title? can it also be done ?

@robinurislamsohan
would it be possible to limit only the yoast variable title?

Improved @keefyhub code to avoid cutting UTF8 chars in half (and avoid breadcrumbs like "sin�…").

function shorten_yoast_breadcrumb_title($link_info)
{
    $limit = 32;
    if (strlen($link_info['text']) > ($limit)) {
        $link_info['text'] = substr(
        $link_info['text'], 
        0, 
        strpos($link_info['text'], ' ', $limit) // added: cut at the first white space after limit
    ) . '…'; }

    return $link_info;
}

add_filter('wpseo_breadcrumb_single_link_info', 'shorten_yoast_breadcrumb_title', 10);

This doesn't work now.

    return $link_info;
}

add_filter('wpseo_breadcrumb_single_link_info', 'shorten_yoast_breadcrumb_title', 10);

Its working on the latest version of Yoast

@vj009007 - Just use the core WordPress wp_trim_words() function which takes care of all that for you ;)
