Yii2 Widget for DataTables plug-in for jQuery

Installation

The preferred way to install this extension is through composer.

Either run

composer require nullref/yii2-datatables

or add

"nullref/yii2-datatables": "~1.0"

to the require section of your composer.json file.

Basic Usage

<?= \nullref\datatable\DataTable::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        'id',
        'name',
        'email'
    ],
]) ?>

For backwards compatibility the old usage via data is still supported

<?= \nullref\datatable\DataTable::widget([
    'data' => $dataProvider->getModels(),
    'columns' => [
        'id',
        'name',
        'email'
    ],
]) ?>

DataTable options

Also you can use all Datatables options

To pass them as widget options:

<?= \nullref\datatable\DataTable::widget([
    'data' => $dataProvider->getModels(),
    'scrollY' => '200px',
    'scrollCollapse' => true,
    'paging' => false,
    'columns' => [
        'name',
        'email'
    ],
    'withColumnFilter' => true,
]) ?>

Specifies header label and css class for cell

    <?= \nullref\datatable\DataTable::widget([
        'columns' => [
            //other columns
            [
                'data' => 'active',
                'title' => 'Is active',
                'sClass' => 'active-cell-css-class',
            ],
        ],
    ]) ?>

Specifies datatable id

<?= \nullref\datatable\DataTable::widget([
    'data' => $dataProvider->getModels(),
    'id' => 'your-datatable-id'
]) ?>

Add Links to row

    <?= \nullref\datatable\DataTable::widget([
        'columns' => [
            //other columns
            [
                'class' => 'nullref\datatable\LinkColumn',
                'url' => ['/model/delete'],
                'linkOptions' => ['data-confirm' => 'Are you sure you want to delete this item?', 'data-method' => 'post'],
                'label' => 'Delete',
            ],
        ],
    ]) ?>

Properties of LinkColumn:

label - text placed in a tag;
title - header title of column;
url - will be passed to Url::to();
linkOptions - HTML options of the a tag;
queryParams - array of params added to url, ['id'] by default;
render - custom render js function. E.g:

//config ...
    'columns' => [
        //...
        [
            'class' => 'nullref\datatable\LinkColumn',
            'queryParams' => ['some_id'],
            'render' => new JsExpression('function render(data, type, row, meta ){
                return "<a href=\"/custom/url/"+row["some_id"]+"\">View</a>"
            }'),
        ],
    ],
//...

You should pass fields that are using at render function to queryParams property

Column filtering

You can add column filtering functionality by setting option withColumnFilter to true :

By default it generates a text field as filter input.
It can be replaced by a combo box using filter parameter when defining column. It should be a associative array where key is used as filter (value sent to server) and value for cell rendering
It can be avoided by setting filter to false

    <?= \nullref\datatable\DataTable::widget([
        'columns' => [
            'id',
            //...
            [
                'data' => 'active',
                'title' => \Yii::t('app', 'Is active'),
                'filter' => ['true' => 'Yes', 'false' => 'No'],
            ],
            [
                'data' => 'last_connection',
                'filter' => false,
            ],
        ],
    ]) ?>
//...

In this example above, filter for active field sent to server will contains 'true' or 'false' but the cell content will be 'Yes' or 'No' and the filter will be rendered as a combo box.

No filter will be generated for last_connection attrribute.

Advanced column definition

Cell rendering or filter can be customized using \nullref\datatable\DataTableColumn class.

    <?= \nullref\datatable\DataTable::widget([
        'columns' => [
            //other columns
            [
                'class' => 'nullref\datatable\DataTableColumn', // can be omitted
                'data' => 'active',
                'renderFiler' => new \yii\web\JsExpression('function() { ' .
                    'return jQuery(\'<input type="checkbox" value="true"/> Active only\'); ' .
                '}'),
                'render' => new \yii\web\JsExpression('function(data, type, row, meta) { ' .
                    'return jQuery(\'<input type="checkbox" value="true" disabled/>\')' .
                    '    .prop(\'checked\', data == \'true\'); ' .
                    '}'),
            ],
        ],
    ]) ?>

Styling

DataTables supports several styling solutions, including Bootstrap, jQuery UI, Foundation.

'assetManager' => [
    'bundles' => [
        'nullref\datatable\assets\DataTableAsset' => [
            'styling' => \nullref\datatable\assets\DataTableAsset::STYLING_BOOTSTRAP,
        ]
    ],
],

Bootstrap

Bootstrap tables require the class 'table', so you'll need to add the 'table' class using tableOptions via the widget config.

<?= \nullref\datatable\DataTable::widget([
    'data' => $dataProvider->getModels(),
    'tableOptions' => [
        'class' => 'table',
    ],
    'columns' => [
        'id',
        'name',
        'email',
    ],
]) ?>

Custom assets

It's possible to use custom styles and scripts:

'nullref\datatable\assets\DataTableAsset' => [
    'sourcePath' => '@webroot/js/plugin/datatables/',
    'js' => [
        'jquery.dataTables-1.10-cust.js',
        'DT_bootstrap.js',
    ],
    'css' => [
        'data-table.css',
    ],
    'styling' => false,
]

Server-side processing

To enable server-side processing add DataTableAction to controller like this:

class SomeController extends Controller
{
    public function actions()
    {
        return [
            'datatables' => [
                'class' => 'nullref\datatable\DataTableAction',
                'query' => Model::find(),
            ],
        ];
    }
}

Searching and ordering can be customized using closures

public function actions()
{
    return [
         'datatables' => [
             'class' => 'nullref\datatable\DataTableAction',
             'query' => Model::find(),
             'applyOrder' => function($query, $columns, $order) {
                //custom ordering logic
                $orderBy = [];
                foreach ($order as $orderItem) {
                    $orderBy[$columns[$orderItem['column']]['data']] = $orderItem['dir'] == 'asc' ? SORT_ASC : SORT_DESC;
                }
                return $query->orderBy($orderBy);
             },
             'applyFilter' => function($query, $columns, $search) {
                //custom search logic
                $modelClass = $query->modelClass;
                $schema = $modelClass::getTableSchema()->columns;
                foreach ($columns as $column) {
                    if ($column['searchable'] == 'true' && array_key_exists($column['data'], $schema) !== false) {
                        $value = empty($search['value']) ? $column['search']['value'] : $search['value'];
                        $query->orFilterWhere(['like', $column['data'], $value]);
                    }
                }
                return $query;
             },
         ],
    ];
}

If you need to get some relation data you can call join or similar methods from $query in applyFilter closure.

You may also specify a closure for query in DataTableAction config if you need complex query like in the following code:

/** ... */
'query' => function() {
    $calculatedValue = calculate_value_for_query();
    
    return Model::find()->where(['calculated_value' => $calculatedValue]);
},
/** ... */

And add options to widget:

<?= \nullref\datatable\DataTable::widget([
    /** ... */
    'serverSide' => true,
    'ajax' => '/site/datatables',
]) ?>

Extra columns

If need to use some custom fields from your model at your render function at column you could pass extraColumns param.

It available at DataTable widget, column and server side action definition:

<?= \nullref\datatable\DataTable::widget([
    /** ... */
    'data' => $dataProvider->getModels(),
    'extraColumns' => ['customPrice'],
    'columns' => [
        [
            'title' => 'Custom column',
            'extraColumns' => ['customField'],
            'render' => new JsExpression($customColumnRender),
        ],
    ],
]) ?>

class SomeController extends Controller
{
    public function actions()
    {
        return [
            'datatables' => [
                'class' => 'nullref\datatable\DataTableAction',
                'query' => Model::find(),
                'extraColumns' => ['customPrice'],
            ],
        ];
    }
}

<?= \nullref\datatable\DataTable::widget([
    /** ... */
    'extraColumns' => ['customPrice'],
]) ?>
