I have a gridview with the code bellow and I have the error Illegal string offset ‘id’

at


$url =  Url::to(['site/archive', 'param' => $param,'pl'=>data['id']]);

how can I fix it?


echo GridView::widget([

    'dataProvider' => $dataProvider,

    'columns' => [

      //  'name',

         [   'attribute'=>'name',

            'class' => 'yii\grid\DataColumn', // can be omitted, as it is the default

            'format'=>'html',

             'value' => function ($data) {

               $url =  Url::to(['site/archive', 'param' => $param,'pl'=>data['id']]);;

                return  Html::a($data['name'], $url) ; // $data['name'] for array data, e.g. using SqlDataProvider.

            },

        ],

        ]

]);

the controller


$count = Yii::$app->db->createCommand('SELECT COUNT(*) FROM plans')

                ->queryScalar();

        $dataProvider = new \yii\data\SqlDataProvider([

            'sql' => 'select id,name from plans  order by name',

            'totalCount' => $count,

            'key' => 'id',

            'sort' => [

                //'defaultOrder' => ['name' => SORT_DESC,],

                'attributes' => [

                    'name',

                    

                ]],

            'pagination' => [

                'pageSize' => 50,

            ]

        ]);

[Edit]It is a typo error data[‘id’] must be $data[‘id’]

Use


$data->id instant of $data['id'].

It should be like this


$url =  Url::to(['site/archive', 'param' => $param,'pl'=>$data->id]);
