For every search, I get ZERO RESULTS, and I don't understand what I'm doing wrong.

 

<?php
require('places_class.php');

$types = $_POST['type'];
$location = $_POST['place'];
$radius = $_POST['radius'];

$gplaces = New GooglePlaces;
$gplaces->SetLocation("$location");
$gplaces->SetRadius($radius);
$gplaces->SetTypes("$types");
$results = $gplaces->Search();

print_r($results);
?>

 

That's when the form is submitted, I checked the variables, and they are echoing out correctly.

 

Then I thought I'd hard-code the values in, same results

<?php
require('places_class.php');

$gplaces = New GooglePlaces;
$gplaces->SetLocation("40.5267,81.4778");
$gplaces->SetRadius(50);
$gplaces->SetTypes("food");
$results = $gplaces->Search();

print_r($results);	
?>

 

Here is the class

<?php
class GooglePlaces
{
	private $APIKey = "";

	public $OutputType = "json";  //either json, xml or array

	public $Errors	= array();

	private $APIUrl = "https://maps.googleapis.com/maps/api/place";

	//Search

	private $Radius;			 		//REQUIRED

		}

}
?>

 

And yes, I do have the correct API Key, I just took it out

 

Can anybody see what the issue is?
