Try following way.
I've assumed your code and provided an example, do the necessary changes as per your need.
Angular Js
console.log("posting data....");
$http({
method: 'POST',
url: '<?php echo base_url(); ?>user/add',
headers: {'Content-Type': 'application/json'},
data: JSON.stringify({name: $scope.name,city:$scope.city})
}).success(function (data) {
console.log(data);
$scope.message = data.status;
});
Controller action
public function add()
{
// Here you will get data from angular ajax request in json format so you have to decode that json data you will get object array in $request variable
$postdata = file_get_contents("php://input");
$request = json_decode($postdata);
$name = $request->name;
$city = $request->city;
$id = $this->user_model->AddUser($name,$city);
if($id)
{
echo $result = '{"status" : "success"}';
}else{
echo $result = '{"status" : "failure"}';
}
}
