I'm retrieving data from a database with AJAX/PHP.How to pass some parameter to the PHP script?

CODE
xmlHttp.open("POST","products.php?parameter=bla",true);
xmlHttp.send(null);

PHP code
CODE
if(isset($_POST['parameter']))
{
    while($products = mysql_fetch_array($result))
   {
      //do something
   }
}

As far as i know that's the right way to do this - xmlHttp.open("POST","something.php?parameter=parameterValue",true).Isn't?When i open the page in the browser and send the request to the server nothing happens,i mean the code in the 'if' block is not executed.The rest of my code in the PHP script works fine so i think that isset($_POST['parameter'])) is the problem.

WHen using the post method you have to change the way you are sending Ajax queries tot he server. You need to do something more like so:

CODE
xmlHttp.open("POST","products.php",true);
xmlHttp.send("parameter=bla");


That way it is posting the variables instead of sending them through the "GET" method.

Hope that helps.
