jquery serialize and $.post

Question

I'm trying to send a lot of data from a form using the $.post method in jQuery. I've used the serialize() function first to make all the form data into one long string which I will then explode serverside. The weird thing is when I try and send it using $.post it appends the result of the serialize() to the URL as if I was sending it using GET. Anyone have any ideas why this is happening?

Here's the jquery:

$("#addShowFormSubmit").click(function(){
  var perfTimes = $("#addShowForm").serialize();
  $.post("includes/add_show.php", {name: $("#showTitle").val(), results: perfTimes }, function(data) {
    $("#addShowSuccess").empty().slideDown("slow").append(data);
  });
});  

here's the php:

$show = $_POST['name'];
$results = $_POST['results'];
$perfs = explode("&", $results);
foreach($perfs as $perf) {
    $perf_key_values = explode("=", $perf);
    $key = urldecode($perf_key_values[0]);
    $values = urldecode($perf_key_values[1]);
}
echo $key, $values;

What leads you to believe that the data is appended to the URL?

Anyway, wouldn't it make more sense to pass the form values in the form data itself? It will allow you to skip the "explode" step:

$("#addShowFormSubmit")
  .click(function() { 
      var perfTimes = $("#addShowForm").serialize(); 
      $.post("includes/add_show.php", 
         $.param({name: $("#showTitle").val()}) + "&" + perfTimes, 
         function(data) {...}); 
  });
