Hi,

I want to limit the ‘description’ field output so I can create a summary on one page and get the full description on another. I know where to place my code, I’m just not sure how to limit the character output of my ‘description’ field.

I have this;
<?php the_field('description'); ?>

Lets say I want to limit the output to 20 words, how can I do that easily?

Thanks
Danny

In this situation, you could try something like this:

Hi @danfloun @smspaul

Exactly! And make sure to use get_field instead of the_field to get the value, and then pass it into the function to trim it down.

Cheers

Okay, this is what I did;

    <?php $summary = get_field('description');
          echo substr($summary, 0, 200); ?> 

That does what I require, thanks.

I would recommend using the built in WP function wp_trim_words.

<?php $excerpt = wp_trim_words( get_field('your_custom_field' ), $num_words = 50, $more = '...' ); ?>
