Controller is firing but I can't get the $_GET

Just send it with POST instead. It's so much easier and your url don't get bloated.

You are adding the following in the url:

Code:

{"lat":41.058304899999996,"long":-74.0711244,"email":"[email protected]"}

But there are no ?email= so it dosen't know you want to pick it up with $_GET.
