Thanks for the post! It was extremely helpful in getting my list feed set up. A small typo I noticed though is in the “set_get_field” function. I was getting an error that I wasn’t providing an owner_id/slug combo, even though I was. So I did some digging and here’s what I fixed:
$this->getfield = $string;
should actually be
$this->get_field = $string;
Once I inserted that underscore it worked perfectly. Again, thanks for the post!
