Hey edmundcwm,
I’m not familiar with the Listify theme, but that variable ( {{data.id}} ) looks like something from a templating language rather than a regular PHP variable. It’s probably converted to the ID after all the PHP work is done (including get_field ).
WordPress has a function to get the ID that may be available to you in the template you are working on. Maybe give this a try:
$post_id = get_the_ID();
echo get_field( 'field_name', post_id );
.. or post a bit more of your code so we can get a better sense of what’s going on!
Hope this helps.
