I have a drag n drop function that takes the position in my db and that puts it in the good order on the screen I can move my boxes around that's all ok but when i move a boxes it's supposed to send it to my db and the line where it doesn't work is  

$.post('updatePanels.php', 'data='+ $.toJSON(sortorder), function(response){ 

I'Ve put the section in blue at the bottom of the script 

function updateWidgetData(){  

    var items=[];  

    $('.column').each(function(){  

        var columnId=$(this).attr('id');  

        $('.dragbox', this).each(function(i){  

            var collapsed=0;  

            if($(this).find('.dragbox-content').css('display')=="none")  

                collapsed=1;  

            //Create Item object for current panel  

            var item={  

                id: $(this).attr('id'),  

                collapsed: collapsed,  

                order : i,  

                column: columnId  

            };  

            //Push item object into items array  

            items.push(item);  

        });  

    });  

    //Assign items array to sortorder JSON variable  

    var sortorder={ items: items };  

  

    //Pass sortorder variable to server using ajax to save state  

     $.post('updatePanels.php', 'data='+$.toJSON(sortorder), function(response){  

        if(response=="success")  

            $("#console").html('<div class="success">Saved</div>').hide().fadeIn(1000);  

        setTimeout(function(){  

            $('#console').fadeOut(1000);  

        }, 2000);  

    });  

}  

</script>
