I have a bug actually with this code.
My JS code is the following:
<script>
var card_Name = "Tour Eiffel";
</script>
I send the data in ajax:
var myDatas = { card_Name: card_Name };
$.ajax({
    type: "POST",
    url: "saveContent.php",
    data: myDatas,
    cache: false,
    contentType: false,
    processData: false,
    success:  function(data){
      alert(data);
    }
}); 
In my PHP i get the element like this:
print_r($_POST['card_Name']);
But nothing is shown in the XHRs parts of my console...
Any idea why ?
Thanks.
