CELL edit with add and delete buttons

For add and delete, here the required the javascript to handle both in CELL edit mode.

Replace "orders" with your own table name. Be sure that edit.php is the correct path relative to your environment.

$dg = new C_DataGrid("SELECT * FROM orders", "orderNumber", "orders");
$dg -> display();

<script type="text/javascript">
$(function() {
    $('#addNew').on('click', function(){
        $("#orders").jqGrid('editGridRow', "new", {url:'/phpGrid/edit.php?dt=json&gn=orders&oper=add'} );

    $('#delRow').on('click', function(){
        var selRowId = $("#orders").jqGrid('getGridParam', 'selrow');
                url: '/phpGrid/edit.php?dt=json&gn=orders',
                data: {'id': selRowId, 'oper': 'del'},
                type: 'POST',
                dataType: 'JSON',
                success: function(){
                        setTimeout(function(){// wait for 5 secs(2)
                          location.reload(); // then reload the page.(3)
                      }, 1000);
        $('#orders').trigger( 'reloadGrid' );
