Error in Editor -DataTables warning: table id=budgetRows_G58201 - Invalid JSON response.

It appears DataTable editor is does not use my POST parms for the where clause.

Console log error in debug

What version of the Editor libraries are you using there? Line 107 is empty in the current file. Likely it is this line that is failing:

$this->_stmt = db2_prepare($resource, $paramSql);

After that line try adding:

if (! $this->_stmt) {
  echo db2_stmt_errormsg();
}

That might give us a clue what is going wrong.

Column or global variable ID not found. SQLCODE=-206

Do you have an ID column in that table?

Allan

bbrindza · April 2023

Hi Allan,

I am using idSrc: id, in the table. The id is a varible passed down from the parent row and is unique. (See line 40 in the JS provided)

Here is the expected returned ajax data

{"data":[{"nextYear_JanuaryBudget":".0","nextYear_FebruaryBudget":".0","nextYear_MarchBudget":".0","nextYear_AprilBudget":".0","nextYear_MayBudget":".0","nextYear_JuneBudget":".0","nextYear_JulyBudget":".0","nextYear_AugustBudget":".0","nextYear_SeptemberBudget":".0","nextYear_OctoberBudget":".0","nextYear_NovemberBudget":".0","nextYear_DecemberBudget":".0"}]}

Here is the front-end script.
This AJAX call is at the Event listener for opening and closing 3nd level child details at


  function format3(rowData) { 
        var childTable = '<table id="budgetRows_' + rowData.productNumber + '" class="display compact wrap w-100 cell-border" width="100%">' +
            '<thead style="display:none"></thead >' +
            '</table>';
        return $(childTable).toArray();
    }
    //*****************************************************************
    // Event listener for opening and closing 3nd level child details 
    //*****************************************************************
    $('tbody').on('click', 'td.detail-level-control_3', function () {
         var tr = $(this).closest('tr');
         var row = childTable2.row(tr);
         var rowData = row.data();

     if (row.child.isShown()) {
         // This row is already open - close it
         row.child.hide();
         tr.removeClass('shown');

         // Destroy the Child Datatable
         $('#budgetRows_' + rowData.productNumber).DataTable().destroy();
     }
     else {
         // Open this row

This is a server-side error though, not client-side.

My guess is that you are defining the third parameter for the Editor::inst() factory to be ID and in fact the column name is id perhaps?

Also if you are using the Editor PHP libraries, don't define idSrc. Editor will handle it for you.

Allan

bbrindza · April 2023

OK I added a compound key to the Editor::inst()

Editor::inst( $db, 'NWFF.PROJLOC', array('PKCUST', 'PKPROD') )

All error went away except for the following..

Uncaught Unable to find row identifier For more information, please refer to https://datatables.net/tn/14

However I do have a DT_RowId

{"data":[{"DT_RowId":"row_25721629eb81G58201","PKRGNO":"5","PKCUST":"2572","PKPROD":"G58201","BD$01":".0","BD$02":".0","BD$03":".0","BD$04":".0","BD$05":".0","BD$06":".0","BD$07":".0","BD$08":".0","BD$09":".0","BD$10":".0","BD$11":".0","BD$12":".0"}],"options":[],"files":[],"draw":1,"recordsTotal":1,"recordsFiltered":1,"debugSql":[]}

The row is returned to the front-end but inline editing is not working

Did you remove the idSrc from the Editor Javascript as well? It should pick DT_RowId automatically, but the error you are seeing would happen if the idSrc option was still there.

All good No errors

Thanks for you help.
