无法在php中发布FormData

Question

I'm trying to use posted FormData form an AJAX call in PHP, but I cannot retrieve the variables. What I'm doing wrong?

here is my Javascript

var sendData = new FormData();
sendData.append('itemid',$('select#selectItems').val());
sendData.append('itemtitle',$('#item-title').val());
sendData.append('itemtext',$('#item-text').val());

$.ajax({
    url: 'ajax.file.php',
    type: 'POST',
    dataType: 'text',
    data: sendData,
    cache: false,
    contentType: false,
    processData: false
});

and my PHP

$itemid = $_POST['itemid'];
echo $itemid;

is always undefined in PHP!

and if I print_r ($_POST);

If I use Firefox the PHP text is:

Array ( [-----------------------------12850217581176488271638880149 Content-Disposition:_form-data;_name] => "itemid" 99 -----------------------------12850217581176488271638880149 Content-Disposition: form-data; name="itemtitle" The Title -----------------------------12850217581176488271638880149 Content-Disposition: form-data; name="itemtext" The Text -----------------------------12850217581176488271638880149-- )

...and using Chrome the PHP response is:

Array ( [------WebKitFormBoundarypyFlwBB31gVYXxRP Content-Disposition:_form-data;_name] => "itemid" 99 ------WebKitFormBoundarypyFlwBB31gVYXxRP Content-Disposition: form-data; name="itemtitle" The Title ------WebKitFormBoundarypyFlwBB31gVYXxRP Content-Disposition: form-data; name="itemtext" The Text ------WebKitFormBoundarypyFlwBB31gVYXxRP-- )

thanks

Try this:

$.ajax({
.
.
beforeSend: function(xhr) {
        xhr.setRequestHeader('Content-Type","application/json');
    }
.
.
});

OR :

$.ajax({
    .
    .
    .
    headers: {"Content-Type","application/json"}
});

</div>
