Codeigniter Angularjs http post not working

Sometimes, you face problem you can't get post data using $this->input->post(), when you fire $http.post() using AngularJS or Jquery. I also face this issue, i can't receive post value when i fire $http.post in AngularJS, But i found how to receive post data or json data in Codeigniter controller. in following example through you can solve your problem:

public function store()

{

 $this->load->database();

 $_POST = json_decode(file_get_contents('php://input'), true);

 $posts = $this->input->post();

 $this->db->insert('posts', $posts);

}
