Answer 1

Change user_name& => user_name look like

function endprogress(){
 $("#surfbar").html("Please wait...");
 var dataString = 'action=validate&t='+adtk; 
        $.ajax({
            type: "POST",
            url: 'yes_manage.php?view=surf&track='+user_name, /*remove & at the end user_name*/
            data: dataString,
            success: function(msg){
                
            }
        });
}
