jQuery AJAX POST request: empty in server

Question

Im sending this AJAX request, but in the server the array is empty. Any help? In Firebug I can see the request is being sent.

  $.ajax({
    type: 'POST',
    url: 'presupuesto_guardar.php',
    data: { 'data': '1' },
  })

//PHP
var_dump($_POST); //this is empty

The request is being sent:

Answer 1

have you write success function to return response if not then please do as below code

$.ajax({
    type: 'POST',
    url: 'presupuesto_guardar.php',
    data: { 'data': '1' },
    success : function(response){
        console.log(response);
    }
})

Please try php://input to get your post data instead of $_POST

php://input will return all the raw data after header

$post = file_get_contents('php://input');

echo json_encode($post);
