# Editor example Always shown checkbox

This example shows a column with checkboxes that are always displayed and will cause a database update when their state is toggled via a click or keyboard action. Although these checkboxes are not actually part of the Editor controlled elements, we can use the Editor API (specifically the `edit()`, `set()` and `submit()` methods) to have Editor perform the action. This can make for very fast editing when working with items that need to be toggled frequently.

A blog post is available that explains in detail how this example is constructed.

First name | Last name | Phone | City | Zip | Active
--- | --- | --- | --- | --- | ---

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

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

`var editor; // use a global for the submit and return data rendering in the examples $(document).ready(function() { editor = new $.fn.dataTable.Editor( { "ajax": "../../controllers/checkbox.php", "table": "#example", "fields": [ { label: "Active:", name: "active", type: "checkbox", separator: "|", options: [ { label: '', value: 1 } ] }, { label: "First name:", name: "first_name" }, { label: "Last name:", name: "last_name" }, { label: "Phone:", name: "phone" }, { label: "City:", name: "city" }, { label: "Zip:", name: "zip" } ] } ); $('#example').DataTable( { dom: "Bfrtip", ajax: "../../controllers/checkbox.php", columns: [ { data: "first_name" }, { data: "last_name" }, { data: "phone" }, { data: "city" }, { data: "zip" }, { data: "active", render: function ( data, type, row ) { if ( type === 'display' ) { return '<input type="checkbox" class="editor-active">'; } return data; }, className: "dt-body-center" } ], select: { style: 'os', selector: 'td:not(:last-child)' // no row selection on last column }, buttons: [ { extend: "create", editor: editor }, { extend: "edit", editor: editor }, { extend: "remove", editor: editor } ], rowCallback: function ( row, data ) { // Set the checked state of the checkbox in the table $('input.editor-active', row).prop( 'checked', data.active == 1 ); } } ); $('#example').on( 'change', 'input.editor-active', function () { editor .edit( $(this).closest('tr'), false ) .set( 'active', $(this).prop( 'checked' ) ? 1 : 0 ) .submit(); } ); } );`

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

- https://code.jquery.com/jquery-3.3.1.js
- https://code.jquery.com/ui/1.12.1/jquery-ui.js
- https://cdn.datatables.net/1.10.20/js/jquery.dataTables.min.js
- https://cdn.datatables.net/buttons/1.6.0/js/dataTables.buttons.min.js
- https://cdn.datatables.net/select/1.3.1/js/dataTables.select.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://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css
- https://cdn.datatables.net/1.10.20/css/jquery.dataTables.min.css
- https://cdn.datatables.net/buttons/1.6.0/css/buttons.dataTables.min.css
- https://cdn.datatables.net/select/1.3.1/css/select.dataTables.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.
