Thanks. Oddly enough, I don’t see any examples of how the ‘fields’ array should be formatted. I do know what my field keys are but, from reading the acf_form docuementation, I have no idea how to add those keys using the fields array.
In your options array, you would format it like this: 'fields' => array('key_123', 'key_321'),
You can find the key for your fields by going to the admin screen for where you edit the fields and click “Screen Options” from the top right and select “Field Keys”. That will show you the key for each field.
