Print an array of variables from droppable area on a new page using ajax

[Yevgeniy_Bagackiy]

I have drag and drop jquery. Accordion that allows user to drag and drop names into a droppable area. So what i want to do is to display dropped names on a new page after user click submit. But I cant get how to do it. I thought maybe its can be done using ajax but not sure how. Thanks in advance. Here is my code:

 <link href="jquery-ui/jquery-ui.css" rel="stylesheet" />
    <script src="jquery-ui/jquery.js"></script>
    <script src="jquery-ui/jquery-ui.js"></script>
    <script>
        $(document).ready(function(){
            $("#myAccordion"). accordion({heightStyle:"content", active: false, collapsible:true});
            $(".source li").draggable({helper:"clone"});
              $("#project ol").droppable({
                activeClass: "ui-state-default",
                hoverClass: "ui-state-hover",
                accept: ":not(.ui-sortable-helper)",
                drop: function(event, ui) 
                {
                    $(this).find(".placeholder").remove();
                    $("<li></li>").text(ui.draggable.text())
                        .addClass("project-item")
                        .addClass('dropClass')
                        .appendTo(this);
                }
            }).sortable({
                items: "li:not(.placeholder)",
                sort: function() {
                    $(this).removeClass("ui-state-default");
                }
            });

            $("#myAccordion ul").droppable({
                drop: function(event, ui) {
                    $(ui.draggable).remove();
                },
                hoverClass: "ui-state-hover",
                accept: '.project-item'
            });

            $('#box').keyup(function(){
                var valThis = $(this).val().toLowerCase();
                if(valThis == ""){
                    $('.source > li').show();           
                } else {
                    $('.source > li').each(function(){
                        var text = $(this).text().toLowerCase();
                        (text.indexOf(valThis) >= 0) ? $(this).show() : $(this).hide();
                    });
               };
            });
        }); 
    </script>
<div id="myAccordion" style="width:20%; float:left; margin-right:30px;">

        $sql = "SELECT username FROM user WHERE username LIKE '".chr($i+32)."%' ";
        $result = $conn->query($sql);       
        if ($result->num_rows > 0) 
        {
            // output data of each row
            while($row = $result->fetch_assoc()) 
            {  
                $name= $row["username"];    
                echo"<li class='ui-state-highlight'>". $name ."</li>";
            }
        } else

            echo "0 results";
        }
