How to limit acf field value in WordPress
If you want to limit the ACF field character output. you can use below code.
1) Make sure to use get_field instead of the_field to get the value.
<?php
$field = get_field('acf_field_name');
echo substr($field, 0, 200);
?>
2) I would recommend using the built in WP function wp_trim_words
<?php
$excerpt = wp_trim_words( get_field('acf_field_name' ),
$num_words = 50, $more = '...' );
?>
