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); ?>
