Intracto DataTables library

Handle AJAX requests for Datatables.net.

Install

composer require intracto/datatables-backend

or

"intracto/datatables-backend" : "dev-master"

Columns

Container class to hold Column objects. This is used to get the field for sorting.

Column

Hold data about a column, can be used for the frontend to render <th> and let DataTables known which fields are sortable and searchable (via javascript).

DataProvider

Get the data to show in the datatable. Requires Parameters, DataTablesRepository, ColumnTransformer.

Parameters

Container class to hold data from the datatables AJAX request.

DataTablesRepositoryInterface

Defines query functions needed to fetch the data.

DataTablesRepositoryTrait

An implementation of DataTablesRepositoryInterface with general queries. Only available for Doctrine ODM for now.

ColumnTransformerInterface

Transform data fetched from the Repository to format needed for the datatables. The order of the fields is important here.


Example

Columns

class AddressListColumns extends Columns
{
    public function __construct()
    {
        parent::__construct(
            array(
                // In order of the tables headers
                new Column('city', 'city', true, true),
                new Column('zip', 'zip', false, false),
                new Column('street', 'street', false, false),
                new Column('actions', 'actions', false, false),
            )
        );
    }
}

Transformer

class AddressListColumnTransformer implements ColumnTransformerInterface
{
    /**
     * @var EngineInterface
     */
    private $renderEngine;

    /**
     * AddressListColumnTransformer constructor
     *
     * @param EngineInterface $renderEngine
     */
    public function __construct(EngineInterface $renderEngine)
    {
        $this->renderEngine = $renderEngine;
    }

    /**
     * @param array $data
     *
     * @return array
     */
    public function transform(array $data)
    {
        $columns = array();

        foreach ($data as $address) {
            /**
             * @var Address $address
             */
            $columns[] = array(
                $address->getCity()
                $address->getZip()
                $address->getStreet()
                $this->renderEngine->render('Address/_list.actions.html.twig', array('address' => $address)),
            );
        }

        return $columns;
    }
}

Repository

class AddressRepository extends DocumentRepository implements DataTablesRepositoryInterface
{
    use DataTablesRepositoryTrait;
}

Controller

public function listAction()
{
    $columns = new AddressListColumns();

    return array(
        'columns' => $columns,
    );
}

public function ajaxListAction(Request $request)
{
    $parameters = Parameters::fromParameterBag($request->query, new AddressListColumns());

    $data = $this->dataTablesDataProvider->getData(
        $parameters,
        $addressRepository,
        $addressListColumnTransformer
    );

    return new JsonResponse($data);
}

Frontend

External JS

Include ajax-datatables.js after loading the official datatables.js plug-in

Twig html

Make sure the table has the "ajaxdatatable" class Loop all the columns in the table head

<table class="ajaxdatatable">
    <thead>
        <tr>
            {% for column in columns %}
                <th>{{ ("translatable.prefix." ~ column.name)|trans }}</th>
            {% endfor %}
        </tr>
    </thead>
</table>

Default sorting needed? Add the class default_sort and asc|desc to the <th> to the correct column

<th {% if column.name == 'email' %} class="default_sort desc"{% endif %}>
    ...
</th>

Twig JS

On the twig page where the ajax datatable must be loaded, place following script block

The filters are optional, here you can pass searchable/filterable fields

<script>
    $(document).ready(function(){

        {# define the ajax call path #}
        var ajaxCallPath = "{{ path("path_to_your_ajax_call") }}";

        {# define which columns are orderable #}
        var sortable = [
            {% for column in columns %}
                {%- if column.orderable -%}
                    {{ 'null' }}
                {%- else -%}
                    {{ '{ "orderable": false }'}}
                {%- endif -%}
                {{ ',' }}
            {% endfor %}
        ];

        {# page load filter fields, do not add .val() since we need the reference #}
        var filters = {
            'name': $("#js-filter-naam"),
            'address.city': $("#js-filter-city")
        };

        {# on page load, init the datatable #}
        ajaxDatatable(ajaxCallPath, sortable, filters, stateSaveAffix);

        {# on submit, change, whenever you want #}
        $(document).on("click", "#js-filter-submit", function(){
            {# no need to pass the parameters again #}
            ajaxDatatable();
        });
    });
</script>
