input post empty - Valerekk - 10-19-2017

Hi guys,
i'm writing a backend in CI (frontend separated in html/js)
when i tried to send POST data to my controller $_POST is empty..
I've tried for few way but i always receive a empty array.
Maybe the problem could be about htaccess???

tried to call my API 
Code:
http://mysite.com/users/register_post_user
two vars
id=test
email=[email protected]
tried already to set url with or without  / at the end    

my controller - Users.php -
PHP Code:
public function register_post_user()
    {
        print_r($_POST);

                //few alternative i tried
        //echo $_POST['id']." ".$_POST['email'];  
        //$id = $this->input->post('id');
        //$email = $this->input->post('email');
        //echo $id." ".$email;
    } 
in that case the result is
Code:
Array ( )

i'm sending request by Postman and my frontend. the result doesn't change.
here my - .htacces - (modified only for removing index.php)

Code:
RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

which js frawework you are using for posting? As I remember I had similar using when I used Angularjs.

RE: input post empty - ponzo - 10-19-2017

Try 


PHP Code:
$_POST = json_decode(file_get_contents("php://input"), true); 

Or if it's not json you're sending without the json_decode

I tried by Jquery, pure Javascript and tool called Postman.

I'm sending two easy vars like => page.php?VAR1=value&VAR2=value2
I'm not sending json data

You're showing how you check if the vars were received, but not how you actually make the request.

RE: input post empty - InsiteFX - 10-20-2017

We need to see your JavaScript code on how you are sending the data etc;

RE: input post empty - Valerekk - 10-20-2017

my js function
Code:
function sendLogin(id, email) {
   $.ajax({
       type: "POST",
       contentType: "application/json; charset=utf-8",
       url: "http://www.plickapp.com/API/index.php/users/register_user/",
       data: "{'idfb':'" + id+ "', 'emailfb':'" + email+ "' }",
       success: function (result) {
            console.log("Ok " + result);
       },
       error: function (result) {
           console.log(result);
       }
  });
}

the frontend is hosted in another space (app, localhost, another server)
so i set the header in my controllers for accepting external request with

PHP Code:
header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: ACCEPT, CONTENT-TYPE, X-CSRF-TOKEN");
header("Access-Control-Allow-Methods: GET, POST, PUT, OPTIONS, DELETE");
header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With"); 

could be the .htaccess ?

-------- UPDATE ----------- 
sending data by GET it works.
example
my request

Code:
http://mysite.com/users/register_post_user/?id=5890459084523908&email=testemail

the result is 
Code:
Array ( [id] => 5890459084523908 [email] => testemail )

tested by URL in browser directly and by Postman....
Huh Huh Huh Huh
