    Maybe this thread helps with the error. There is many more on this topic in the forum.
    https://datatables.net/forums/discussion/comment/171282/#Comment_171282

    You are declaring the data table here:

    var $dTable = $('#example').DataTable({ ...
    

    and here you are doing it again. Hence the error I guess.

    $('#example').DataTable( { ...
    

    I would pull the configuration of the data table together to avoid this problem.

    Maybe something similar to this:

    var $dTable = $('#example').DataTable({
        "dom": "<'row'<'col-sm-4'l><'col-sm-5' <'datesearchbox'>><'col-sm-3'f>>" +
          "<'row'<'col-sm-12'tr>>" +
          "<'row'<'col-sm-5'i><'col-sm-7'p>>",
        "footerCallback": function ( row, data, start, end, display ) {
                var api = this.api();
      
                // Remove the formatting to get integer data for summation
                var intVal = function ( i ) {
                    return typeof i === 'string' ?
                        i.replace(/[\$,]/g, '')*1 :
                        typeof i === 'number' ?
                            i : 0;
                };
      
                // Total over all pages
                total = api
                    .column( 4 )
                    .data()
                    .reduce( function (a, b) {
                        return intVal(a) + intVal(b);
                    }, 0 );
      
                // Total over this page
                pageTotal = api
                    .column( 4, { page: 'current'} )
                    .data()
                    .reduce( function (a, b) {
                        return intVal(a) + intVal(b);
                    }, 0 );
      
                    $(api.column(4).footer()).html(this.fnSettings().fnFormatNumber( 'Rp ' +pageTotal));
                // Update footer
                // $( api.column( 4 ).footer() ).html(
                //     'Rp '+pageTotal +' '
                // );
            }
    

    Didn't check the syntax; maybe brackets or commas are missing.

    then how to combine this 2 functions. first i need date time filter, second i need too callback footer to sum the coloums.

  • rf1234rf1234 Posts: 2,522Questions: 79Answers: 368

    Then don't use the callback option but use the api, e.g. this
    https://datatables.net/reference/api/columns().footer()

    This way you can do the footer later. You should also take a look at the event list to find the suitable event when to do the footer:
    https://datatables.net/reference/event/

    It is probably the "draw" event that you will require. So that the footer is being recalculated on each table draw.

  • dika0094dika0094 Posts: 6Questions: 1Answers: 0

    i dont understand. can u help me write full code to combine that?

  • colincolin Posts: 14,610Questions: 1Answers: 2,493

    We're happy to take a look, but as per the forum rules, please link to a test case - a test case that replicates the issue will ensure you'll get a quick and accurate response. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.

    Cheers,

            //     'Rp '+pageTotal +' '
            // );
        } );
    

    This is using the "draw" event. I just copied your code from the callback into the event handler. Don't know whether "draw" is appropriate for your use case. If not take a different event, e.g. "init". The reference to the data table is simpler using an event. You don't need "this.api()" but just the data table variable name.

    can u write full code please? I don't understand how to implement the instructions you gave

  • rf1234rf1234 Posts: 2,522Questions: 79Answers: 368

    I think I wrote almost all of your code already. Please post a test case.

    this almost done, but date range filter foem dosent work

    http://live.datatables.net/letokuya/6/edit

  • colincolin Posts: 14,610Questions: 1Answers: 2,493

    I'm not clear how the date range filter is supposed to work. Your code is referring to start_date and end_date, but you only have a single date control on the page.
