# Editor example Server-side processing

When using server-side processing, rather than passing `this` into the `inline()` method (where `this` is the `td` cell) we need to translate the cell node into an index using `cell().index()`. The reason for this is that when server-side processing is enabled, each redraw will refresh the table, resulting in the original cell no longer being in the document (it has been discarded and replaced). Using the cell index allows the reference to the correct cell to be maintained over the redraw.

This example shows that in practice.

| First name | Last name | Position | Office | Start date | Salary
--- | --- | --- | --- | --- | --- | ---

- Javascript
- HTML
- CSS
- Ajax
- Server-side script

The Javascript shown below is used to initialise the table shown in this example:

`var editor = new DataTable.Editor({ ajax: '../../controllers/staff.php', fields: [ { label: 'First name:', name: 'first_name' }, { label: 'Last name:', name: 'last_name' }, { label: 'Position:', name: 'position' }, { label: 'Office:', name: 'office' }, { label: 'Extension:', name: 'extn' }, { label: 'Start date:', name: 'start_date', type: 'datetime' }, { label: 'Salary:', name: 'salary' } ], table: '#example' }); var table = $('#example').DataTable({ ajax: { url: '../../controllers/staff.php', type: 'POST' }, buttons: [ { extend: 'create', editor: editor }, { extend: 'edit', editor: editor }, { extend: 'remove', editor: editor } ], columns: [ { data: null, defaultContent: '', className: 'select-checkbox', orderable: false, searchable: false }, { data: 'first_name' }, { data: 'last_name' }, { data: 'position' }, { data: 'office' }, { data: 'start_date' }, { data: 'salary', render: DataTable.render.number(null, null, 0, '$') } ], dom: 'Bfrtip', order: [[1, 'asc']], select: { selector: 'td:first-child', style: 'os' }, serverSide: true }); // Activate an inline edit on click of a table cell $('#example').on('click', 'tbody td:not(:first-child)', function (e) { editor.inline(table.cell(this).index(), { onBlur: 'submit' }); });`
`const editor = new DataTable.Editor({ ajax: '../../controllers/staff.php', fields: [ { label: 'First name:', name: 'first_name' }, { label: 'Last name:', name: 'last_name' }, { label: 'Position:', name: 'position' }, { label: 'Office:', name: 'office' }, { label: 'Extension:', name: 'extn' }, { label: 'Start date:', name: 'start_date', type: 'datetime' }, { label: 'Salary:', name: 'salary' } ], table: '#example' }); const table = new DataTable('#example', { ajax: { url: '../../controllers/staff.php', type: 'POST' }, buttons: [ { extend: 'create', editor }, { extend: 'edit', editor }, { extend: 'remove', editor } ], columns: [ { data: null, defaultContent: '', className: 'select-checkbox', orderable: false, searchable: false }, { data: 'first_name' }, { data: 'last_name' }, { data: 'position' }, { data: 'office' }, { data: 'start_date' }, { data: 'salary', render: DataTable.render.number(null, null, 0, '$') } ], dom: 'Bfrtip', order: [[1, 'asc']], select: { selector: 'td:first-child', style: 'os' }, serverSide: true }); // Activate an inline edit on click of a table cell table.on('click', 'tbody td:not(:first-child)', function (e) { editor.inline(table.cell(this).index(), { onBlur: 'submit' }); });`

In addition to the above code, the following Javascript library files are loaded for use in this example:

- https://code.jquery.com/jquery-3.7.0.js
- https://cdn.datatables.net/1.13.5/js/jquery.dataTables.min.js
- https://cdn.datatables.net/buttons/2.4.1/js/dataTables.buttons.min.js
- https://cdn.datatables.net/select/1.7.0/js/dataTables.select.min.js
- https://cdn.datatables.net/datetime/1.5.1/js/dataTables.dateTime.min.js
- ../../js/dataTables.editor.min.js

The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:

This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The additional CSS used is shown below:

``

The following CSS library files are loaded for use in this example to provide the styling of the table:

- https://cdn.datatables.net/1.13.5/css/jquery.dataTables.min.css
- https://cdn.datatables.net/buttons/2.4.1/css/buttons.dataTables.min.css
- https://cdn.datatables.net/select/1.7.0/css/select.dataTables.min.css
- https://cdn.datatables.net/datetime/1.5.1/css/dataTables.dateTime.min.css
- ../../css/editor.dataTables.min.css

This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.

The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation.
