Yii2 Grid view sort and filteration using custom label

Question

In my user table I have fields like firstname and lastname. then I generated a views using Gii.In my index page now I have Firstname,Lastname,Username etc....

I concatenated my fistname and lastname as Name.

[
  'attribute'=>'firstname',
  'label' => 'Name',
  'format' => 'raw',
  'value' => function ($data) {
   return Html::a($data->Name);
   },
],

In Model

public function getName()
{
    return $this->firstname.' '.$this->lastname;
}

unfortunately I am unable to search the name field with last name... I need to filter the field with both firstname and lastname.
Can anyone please help me....
Thanks in advance.

This is how you setup search model (I did not include your other columns, so dont forget on those)

You can find more here: http://www.yiiframework.com/wiki/621/filter-sort-by-calculated-related-fields-in-gridview-yii-2-0/

class UserSearch extends User
{
    public $name;

    public function rules()
    {
        return [
            [['name'], 'safe'],
            // some other rules ...
        ];
    }

    public function scenarios()
    {
        // bypass scenarios() implementation in the parent class
        return Model::scenarios();
    }

    public function search($params)
    {
        $query = User::find();

        $dataProvider = new ActiveDataProvider([
            'query' => $query,
        ]);

        $dataProvider->sort->attributes['name'] = [
            'asc' => ['lastname' => SORT_ASC, 'firstname' => SORT_ASC],
            'desc' => ['lastname' => SORT_DESC, 'firstname' => SORT_DESC],
            'label' => 'Name',
            'default' => SORT_ASC
        ];

        $this->load($params);

        if (!$this->validate()) {
            // uncomment the following line if you do not want to return any records when validation fails
            // $query->where('0=1');
            return $dataProvider;
        }

        // grid filtering conditions

        // some other filters ...
        $query->andFilterWhere([
           'or',
            ['like', 'lastname', $this->name],
            ['like', 'firstname', $this->name],
        ]);

        return $dataProvider;
    }
}

And in your gridview instead of

[
  'attribute'=>'firstname',
  // ...
],

just use

[
  'attribute'=>'name',
],
