   $(document).ready(function(){     $("#retrievelist").on('click',function() {         var xid = $('#xid').val();         var date = $('#date').val();         $.post('retrieve_test.php',{xid:xid, date:date}, function(data){         $("#results").html(data);         });         return false;     });  $("#report").on('click',function() {     var dates = $('#date').val();         $.post('report_sample.php',{dates:dates}, function(data){         $("#results").html(data);         });         return false;     });  $("#email").on('click',function() {     var date1 = $('#date').val();         $.post('mail.php',{date1:date1, output:output}, function(data){         $("#results").html(data);         });         return false;     });     }); 

$dates = $_post['dates']; $output= $_post['$output']; 

should be

$dates = $_post['date1']; $output= $_post['output'];
