Need help in passing value form JS to PHP

Question

I have some problem with passing value from javascript file to php file. I make some calculations in JS, and after that i passing it to php. This is a code of JS:

var price=100;// for example

            $.ajax({
            type: "POST",
            url: "SecureRide.php",
            data: { calculatedPrice: price }
        });

And this is a code of PHP:

<?php 
session_name("ridePrice");
session_start();

$_SESSION["calculatedPrice"]=$_POST["calculatedPrice"];
echo $_SESSION["calculatedPrice"];

?>

So what i do is a simple Ajax function that passes the value to php, very simple, but doesn't work! When I do echo function there's nothing there. Maybe there are another way to solve it? Thank you very much!

Try checking your web developer tools to see if the ajax is posting and what response you are getting. — chrislondon, Jul 03 '13 at 15:07
Also, specify the contentType for the $.ajax function. By default it sends it as `application/x-www-form-urlencoded; charset=UTF-8`. You need to use `application/json` or something of the like. — GJK, Jul 03 '13 at 15:10
I've done it already, ajax is posting and I do get the exact value i need, And yes, Jquery included — Karb, Jul 03 '13 at 15:11
Where do you expect output to occur here and where are you looking for it exactly? — deceze, Jul 03 '13 at 15:13
is secureRide.php an example or is maybe the page on another domani? in this case you'll have to use jsonp for the request — nowhere, Jul 03 '13 at 15:13
Do you firebug installed? Can you see the request going out and the response coming back? — Pitchinnate, Jul 03 '13 at 15:14

Note : if you are put your ajax code in function and than call function from the "$(document).ready(function(){" then your code run perfectly

I write code in your .js file :

$(document).ready(function(){
functionName(price);
});

function functionName(price){

 $.ajax({

  url: 'SecureRide.php', 
  data:{calculatedPrice: price},
  type: 'POST',
     success:function(data)
     {
      alert(data);           
     }, 
     error:function(data) 
     { 
     alert("mistake in your code");
     } 
   }) 
 }

And Code For PHP file for get .JS File Data

if(isset($_POST['calculatedPrice']) && !empty($_POST['calculatedPrice'])) 
  {
  $calculatedPrice1=$_POST['calculatedPrice'];
  }
