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"}';
    }
}

You can do it on server side and send the validation success / failure message accordingly Ex. $_POST = json_decode(file_get_contents("php://input"), true); $this->form_validation->set_rules($data->name, 'Name', 'trim|required|min_length[3]'); if(!$this->form_validation->run()) { echo $result = '{"errors" : validation_errors()}'; }

@Nepster See how codeigniter do the validation But you need to get the post data and then you need to check validation and then return the result to client (angular) and show that message.
