Is there a trick to passing a the_sub_field value through one of these functions? I am using both but neither one of them seem to be working.

Example:

<h2 id=”<?= strtolower(str_replace(array(‘ ‘, ‘:’), array(‘-‘, ”), the_sub_field(‘section_name’))); ?>”><?= the_sub_field(‘section_name’); ?></h2>

the_sub_field() as with the_field() echos the value of a field rather than return it. You need to use get_sub_field() which returns a values so that you can do something with it.

Ah, makes sense!
