Getting Requested unknown parameter '0' for row 0 Error in datatables server side












0














This is a frequently asked question, but I haven't found a solution in the existing threads. It typically points to a mismatch between headers and cells, but I believe that's not the case here. Maybe I'm just looking past it...



My JSON...



{"draw": 1, "recordsTotal": 5, "recordsFiltered": 5, "data": [{"fName":"Ida","lName":"Black"},{"fName":"Gwen","lName":"Sharp"},{"fName":"Sharon","lName":"Sullivan"},{"fName":"Claudette","lName":"Tidwell"},{"fName":"Ellie","lName":"Westman"}]}


My HTML...



                      <table id="datatable_tabletools" width="100%">

                            <thead>

                                <tr>

                            </tfoot>

                      </table>

  • I don't see the name of the action in the network tab. Datatables does seem to be aware of the number of rows returned though. Although I specify 5 rows above, I was previously not doing that, and the rows displayed in datatables were correct, but blank and I got the error above.

You need to specify data property names for each column using columns.data option.



Also you should be using ajax.url option to define data source URL if you are using Ajax-sourced data.



For example:



$('#datatable_tabletools').dataTable({

   "processing": true,

   "serverSide": true,

   "ajax": {

      "url": "../contacts/returnjson"

   },

   "columns": [

      { "data": "fName" },

      { "data": "lName" }

   ]

});
