How to retrieve parameters sent with http.get - php

Question

I am using http.get to get data from database. I am sending the parameters along with url. but the parameters are not accessible from that url.
Here is my Angularjs controller code :
app.controller('ListCtrl', ['$scope', '$http', '$location', '$window', function($scope,$http,$location,$window){
$scope.data = {};
$scope.getdata = function(){
$scope.datas = [];
$http({
url: "http://localhost/angular/data.php",
method: "GET",
params: {'place':$scope.data.place,'pincode':$scope.data.pincode}
})
.success(function(data,status,headers,config){
$scope.datas=data;
console.log($scope.datas);
$scope.navig('/show.html');
})
.error(function(){
alert("failed");
});
};
$scope.navig = function(url){
$window.location.href = url;
};
}])
And here is my data.php file
<?php
header("Access-Control-Allow-Origin: *");
$postdata = file_get_contents("php://input");
$data= json_decode($postdata);
$place = mysql_real_escape_string($data->place);
$pincode = mysql_real_escape_string($data->pincode);
//$place = $_GET[$data->place];
if ($place){
$connection = mysqli_connect("localhost","root","","building") or die("Error " . mysqli_error($connection));
$sql = "SELECT * from details ";
$result = mysqli_query($connection, $sql) or die("Error in Selecting " . mysqli_error($connection));
$detail = array();
while($row =mysqli_fetch_assoc($result))
{
$detail[] = $row;
}
echo json_encode($detail);
mysqli_close($connection);
}
else {
echo "no place entered";
}
?>
It outputs as "no place entered" even if I enter the place.
Is that the right way to retrieve the data?
I am passing either place or pincode, not both. will that cause any issue?
please help.

Answer 1

Solved it. Here is the solution.
I used these two line of code
$place = $_GET['place'];
$pincode= $_GET['pincode'];
instead of these 4 lines of code which is actually used to retrieve data sent with http.post
$postdata = file_get_contents("php://input");
$data= json_decode($postdata);
$place = mysql_real_escape_string($data->place);
$pincode = mysql_real_escape_string($data->pincode);
