pass html form data to json php string - php

Question

I've been able to perform a parse to post data to my api using this format:
Working sample:
<?php
$appId = 'XXXXXXXXXXXXXXXXXXXXXXXXXXX';
$private_token = 'XXXXXXXXXXXXXXXXXXX';
$geo_post = "/api/v1/geofence/";
$name = "Home";
$latitude = 38.646322;
$longitude = -121.185837;
$radius = 50;
$data = array(
"name" => $name,
"location" =>
array( "latitude" => $latitude, "longitude" => $longitude),
"matchRange" => $radius
);
$data_string = json_encode($data);
$ch = curl_init();
$headers = array(
'Content-Type:application/json',
'Authorization: Basic '. base64_encode($appId.":".$private_token) // <---
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, 'https://admin.plotprojects.com' . $geo_post );
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$content = trim(curl_exec($ch));
curl_close($ch);
//print_r($content);
?>
Sample with Error message:
<?php
if (isset($_REQUEST['add_new'])){
$appId = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
$private_token = 'XXXXXXXXXXXXXXXXXXXXXXX';
$geo_post = "/api/v1/geofence/";
$name = $_GET['db_geofencename'];
$latitude = $_GET['db_latitude'];
$longitude = $_GET['db_longitude'];
$radius = $_GET['db_radius'];
$data = array(
"name" => $name,
"location" =>
array( "latitude" => $latitude, "longitude" => $longitude),
"matchRange" => $radius
);
$data_string = json_encode($data);
$ch = curl_init();
$headers = array(
'Content-Type:application/json',
'Authorization: Basic '. base64_encode($appId.":".$private_token) // <---
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, 'https://admin.plotprojects.com' . $geo_post );
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$content = trim(curl_exec($ch));
curl_close($ch);
print_r($content);
?>
As you can see I'm using a string in my $data array, so i'm trying to capture the information from the form and pass it to the $data array, but if I use $_GET or $_POST i end up with an error message:
{ "success": false, "errorMessage": "The request content was malformed:\nExpected String as JsString, but got null", "errorCode": "BadRequest" }
what is it I'm doing wrong?

So best i can think of is convert(type cast) your $latitude and $longitude into floating numbers. Don't depend on php auto type casting as some times internally it will keep it as string and i guess that api want $latitude and $lon... as floating numbers not strings.
