jQuery + Ajax form submission, PHP doesn't get any data - php

Question

I am trying to submit a form that only has a radiobutton group with name=radiob. This is the script I am using for submitting data:
<script type="text/javascript">
$(function() {
$("#myForm").submit(function() {
var dataString = $(this).serialize();
$.ajax({
type: "POST",
url: "index.php?p1=<?php echo $_GET['p1']; ?>",
data: dataString,
success: function() {
$("#ppm").fadeOut("slow");
$("#ppmPlugin").load('?p1=<?php echo $_GET['p1'];?>&result=true');
}
});
return false;
});
});
</script>
But this is what I get in my PHP script:
$_POST array - empty
Array ( )
$_GET array
Array ( [p1] => xxx [result] => true )
But if I alert(dataString); I get radiob=2, that is, the value depending on the radiobutton selected..
How do I fix this problem?

I've tested your code and it works fine. Perhaps you have some kind of redirect in index.php?p1=xxx.
P.S. Tested with this code:
<?php $_GET['p1'] = 1; ?>
<form id="myForm">
<input type="radio" name="radiob" value="1" />
<input type="radio" name="radiob" value="2" />
<input type="submit" value="Submit" />
</form>
<script type="text/javascript">
$(function() {
$("#myForm").submit(function() {
var dataString = $(this).serialize();
$.ajax({
type: "POST",
url: "index.php?p1=<?php echo $_GET['p1']; ?>",
data: dataString,
success: function(data) {
alert(data);
}
});
return false;
});
});
</script>
And in index.php I have
<?php var_dump($_GET, $_POST); ?>
