PHP-AJAX; POST METHOD problem

Question

I am using ajax, php with my application. In sending the data from ajax to php, when i use the $_GET, I can have the data. but when i try to use $_POST since i read it is more secure, it cannot access the data. When i echo the value, it's blank.

I tried changing the register_globals = off to on in the php.ini, but still not working.

did i miss out on something?

this is my js file:

var params=arguments[0].options[arguments[0].selectedIndex].value;
 var url = "http://localhost/myprocess.php";
 ajaxRequest.open("POST",url, true);

 ajaxRequest.setRequestHeader("Content-type","application/x-www-form-urlencoded");
 ajaxRequest.setRequestHeader("Content-length",params.length);
 ajaxRequest.setRequestHeader("Connection", "close");

 ajaxRequest.onreadystatechange = function(){
     if ((ajaxRequest.readyState == 4) && (ajaxRequest.status == 200)) 
    {
    //Get data from server's response
    alert("response text is:");
    alert(ajaxRequest.responseText);   -->does not show anything; blank
   }
  }
 ajaxRequest.send(params);
}

php file

<?php
$selectedID = $_POST['params'];
echo "hello there ". $selectedID;
?>

thanks a lot, tinks

I don't see you specifying a key for the data that's being POSTed, which is what your PHP script is looking for.

Try changing ajaxRequest.send(params); to ajaxRequest.send("params=" + params);

Yeah you need to specify a key. The post method on this link might help:
