Question

I am trying to post an array of check box ids to an action in my controller. Here is the script from my index.ctp:

<script type="text/javascript">
$('.editSel_dialog').click(function()
{
    var selected = [];
    alert('Edit Selected Has Been Clicked');

    $("#[id*=LocalClocks]").each(function()
        {
        if(false != $(this).is(':checked'))
        {
            selected.push($(this).attr('id').replace('LocalClocks', ''));
        }
    });
    alert(selected);
    /*$.ajax(
    {
        type: 'POST',
        url: "/LocalClocks/editSelected/",
        data: selected,
        traditional: true,
        //contentType: "application/json",
        dataType: "text",
        success: function(data){ alert(data); alert('Edit Success');}
    });*/
    $.post('/LocalClocks/editSelected', { "Session" : selected }, function(data){
                   alert(data);
    });
});
</script>

I have both an ajax request and a post request. I was using the ajax until I saw that the post can actually modify a php variable. The code in the braces { "Session" : selected } should modify the Session variable with the array selected.

I tried using debug on $this->data, and $this->request->data, and $_POST, but they all are empty.

I need help getting the selected array written to a variable or something. I was thinking of trying to write to $this->Session but I am not sure how I would go about doing that.

Thanks in advance

With Cake, to get posted values in $this->request->data, their names have to be prefixed with data:

Javascript:

$.post('/LocalClocks/editSelected', { "data[Session][selected]" : selected }, function(data){
               alert(data);
});

Controller:

function editSelected()
{
  if($this->request->is('post'))
  {
    if(isset($this->request->data['Session']['selected']))
    {
      $this->Session->write('selected', $this->request->data['Session']['selected']);
    }
  }
}
