Hi @darktakua
In that case, you can check if the rep_last_name field has a value or not. If it does, then show the template like this:
<?php
if( get_field('rep_last_name') ){
?>
<div="<?php the_field('rep_last_name'); ?>" class=
...
...
...
</span>
<?php } ?>
Regarding the shortcode, you need to use it like this:
[acf field="rep_last_name"]
You need to put the echo code in your template. So instead of
the_field('rep_card_content');
You need to use this:
echo do_shortcode(get_field(‘rep_card_content’));
I hope this helps 🙂
