Grab Photo ID
Assuming the max number of photos is 1, this expression grabs the one photo id in the form and adds it to the feature id field. $feature_id and $photos are both strings, so you can add them together with a '+'.
Note
Photo elements have two properties. They look like this:
json {"photo_id: "", "caption": "Test caption"}.
var photo;
if ($photos.length > 0) {
photo = $photos[0].photo_id;
SETRESULT($feature_id + photo);
} else {
SETRESULT('');
}
