For the JS  try  data   id  the id      success  function data            alert  the server returned     data          and   the id   intval   POST  id       in PHP

So what does count votes look like   Is it a script   Anything that you want to get back from an ajax call can be retrieved using a simple echo  of course you could use JSON or xml  but for this simple example you would just need to output something in count votes php like    id     POST  id     function getVotes  id          call your database here      query     SELECT votes FROM poll WHERE ID    id         result    mysql query  query        row   mysql fetch row  result        return  row- gt votes     votes   getVotes  id   echo  votes    This is just pseudocode  but should give you  the idea   What ever you echo from count votes will be what is returned to  data  in your ajax call

ajax               type   POST               data   data the id               url   http   localhost test index php data count votes               success  function data                    data will contain the vote count echoed by the controller i e                      yourVoteCount                  then append the result where ever you want like                  span votes number   html data     data will be containing the vote count which you have echoed from the controller                                      in the controller    data     POST  data        data will contain the id   do some processing echo  yourVoteCount     Clarification  i think you are confusing    data the id    with   success function data     both the data are different for your own clarity sake you can modify it as  success function vote count     span someId  html vote count
