Ahh I used to be one too, then I became both after a while 😉 It’s inevitable in a small business
Anyway, this should do it provided that both fields are arrays!
<?php $checkboxValues = get_field('field_name'); //Change field_name to your checkbox field $morecheckboxValues = get_field('field_name_2'); //Change field_name to your checkbox field $extraClasses = array_merge($checkboxValues, $morecheckboxValues); ?> <?php post_class( $extraClasses ); //This goes in your <article> element (or whatever you use) ?>
