    </script>

server side code:

print_r($_POST["data"]);

die(" dddd ");

Thanks all for support. It seems when $.post is used for json data transfer, we need to use the parameter in callback function for client to server data transfer as well as server to client.

So code changes required was: var json = $("#formTesti:input").serializeArray();

答

You have to pass key value pair for data in post.. not data variable.. something like this

$.post( "test.php", { name: "John", time: "2pm" } );

答

var data = $("#formTesti").serialize();
$.post(
    "serviceTestimonials.php",
    data: data,
    function(json){
      if(json.status="fail")
          alert(json.message());
      else {

      }
   },
"json"
);
