$this->post codeigniter don't work with rest api

Question

I tried to work with $this->post() to get data sent by post in json format. By I can not get any result of for example $this->post('name').

This is the code :

<?php

require(APPPATH . '/libraries/REST_Controller.php');

class user_api extends REST_Controller {

    function user_post() {

                $user = array(
                    'id' => null,
                    'firstname' => $this->post('firstname'),
                    'lastname' => $this->post('lastname')
                );

                $result = $this->user_model->insert($user);
                if ($result) {
                    $this->response($result, 200); // 200 being the HTTP response code
                } else {
                    $this->response(NULL, 404);
                }
    }

}

?>

data sent on json format to the link : http://mydomain.com/myapplication/user_api/user :

{"firstname":"test",
"lastname":"test"
}

There is no data in the database like it can not get data from $this->post('firstname').

Any idea ????

Solution 1

json data you can't get through post method you have to use like this

require(APPPATH . '/libraries/REST_Controller.php');

class user_api extends REST_Controller {

    function user_post() {

       $params = json_decode(file_get_contents('php://input'), TRUE);

        $user = array(
            'id' => null,
            'firstname' => $params['firstname'],
            'lastname' => $params['lastname']
        );

        $result = $this->user_model->insert($user);
        if ($result) {
            $this->response($result, 200); // 200 being the HTTP response code
        } else {
            $this->response(NULL, 404);
        }
    }

}

Solution 2

//You should use

$array=array(
'firstName'   => $this->input->post("firstName"),
'lastName'   => $this->input->post("lastName")
);

Solution 3

I think you are not using the correct function to get the values you want the posted data but you are trying to get in $this->post('name')

you should use the CI's method to get the values like

$this->input->post('name');

or

$this->input->get('name');


            $user = array(
                'id' => null,
                'firstname' => $this->input->post('firstname'),
                'lastname' => $this->input->post('lastname')
            );

You should take a look at Input class
