Thanks @acf-support !
What I posted in my code above is after trying just about everything. I tried placing the the slug (irish-eyes) in the get_post_type() function and it didn’t work either.
As for the $_POST[‘acf’] variable, I tried get_fields() as well. In my followup comment from above, I was able to finally get it to save to the post content, but this is what it saves:
before the fieldsArrayafter the fields
How to I get that “Array” text to save all the content of the fields from the post and not the word Array?
