Topic: Limit characters on next/prev post titles

Hi, I’m using {{post_title source:next-post}} in buttons to show the title of the next or previous post. This works well but I’m wondering how I set a max character limit on this as a few of the post titles are too long and it doesn’t look great?

Many thanks.

Hi there,

You can try this snippet:

add_filter('generateblocks_dynamic_tag_output', function ($output, $options) {
    if (isset($options['trim-title'])) {
        if (!empty($output)) {
            $num_words = !empty($options['trim-title']) && is_numeric($options['trim-title']) 
                ? intval($options['trim-title']) 
                : 3;
            return wp_trim_words($output, $num_words, '...');
        }
    }
    return $output;
}, 10, 2);

Then, in your dynamic tag, use it like this:
{{post_title source:next-post|trim-title}}
By default, it will trim the title to 3 words.

If you want to specify a custom word count (e.g., 4 words), use:
{{post_title source:next-post|trim-title:4}}
