GridView Widget

Make item clickable link
[
    'attribute'=>'naam',
    'label' => 'Studentnaam',
    'contentOptions' => ['style' => 'width:600px; white-space: normal;'],
    'format' => 'raw',
    'value' => function ($data) {
        return Html::a($data->naam, ['/examen/update?id='.$data->id],['title'=> 'Edit',]);
     },
],

// for related table values, use
'value' => 'student.locatie',
Title of column name

Change the model, example:

public function attributeLabels() {
	return [
		'id' => 'ID',
		'naam' => 'examennaam',
		'datum_van' => 'van',
		'datum_tot' => 'tot',
		'actief' => 'actief',
	];
}

The database column 'datum_van' will be showed as 'van'.

View column conditionally
[
    'class' => 'yii\grid\ActionColumn',
    'contentOptions' => ['style' => 'width:400px; white-space: normal;'],
    'header'=>'Actions',
    'template' => '{view} {update} {delete}',
    'visibleButtons'=>[
        'view'=> function($model){
              return $model->status!=1;
         },
    ]
],
Add own controller (copy)
[
    'class' => 'yii\grid\ActionColumn',
    'template' => '{download} {view} {update} {delete}',
    'buttons' => [
        'download' => function ($url) {
            return Html::a(
                '<span class="glyphicon glyphicon-arrow-down"></span>',
              	['another-controller/anotner-action', 'id' => $model->id],   // mag ook alleen url als je geen parameter wilt meegeven, dan hoef je geen array te maken.
                [
                    'title' => 'Download',
                    'data-pjax' => '0',
                ]
            );
        },
    ],
],

// Alternatief, copy button, niet vergeten in template te te zetten
    'buttons'=>[
         'copy' => function ($url, $model, $key) {
             return Html::a('<span class="glyphicon glyphicon-copy"></span>', ['copy', 'id'=>$model->id],['title'=>'Copy']);
         },
    ],
Boolean (toggle icon)

Show boolean, if clicked, change status.

 [
   'attribute'=>'actief',
   'contentOptions' => ['style' => 'width:10px;'],
   'format' => 'raw',
       'value' => function ($data) {
         	// $status = icon 'ok' or icon 'minus' depending on $data->ctief
            $status = $data->actief ? '<span class="glyphicon glyphicon-ok"></span>' : '<span class="glyphicon glyphicon-minus"></span>';
            return Html::a($status, '/rolspeler/toggle-actief?id='.$data->id);
        }
 ],

// Controller
 public function actionToggleActief($id) {
        // function toggles boolean actief, in this example only one row can be active, so we execute two queries
        $sql="update examen set actief=1 where id = :id; update examen set actief=0 where id != :id;";
        $params = array(':id'=> $id);
        Yii::$app->db->createCommand($sql)->bindValues($params)->execute();
        return $this->redirect(['index']); // go back to view
    }

In this example only one row can be active. If you want a simple toggle use SQL statement:

update <table> set abss(active = active-1)
Drop down in grid select

https://stackoverflow.com/questions/29231013/how-can-i-use-a-simple-dropdown-list-in-the-search-box-of-gridviewwidget-yii2

[
    'attribute'=>'attribute name',
    'filter'=>array("ID1"=>"Name1","ID2"=>"Name2"),
],

// of

[
    'attribute'=>'attribute name',
    'filter'=>ArrayHelper::map(Model::find()->asArray()->all(), 'ID', 'Name'),
],

// of

[
    'attribute' => 'attribute_name',
    'value' => 'attribute_value',
    'filter' => Html::activeDropDownList(
      				$searchModel,
      				'attribute_name',
                    ArrayHelper::map(ModelName::find()->asArray()->all(), 'ID', 'Name'),
                    ['class'=>'form-control','prompt' => 'Select Category']
                ),
],

In dit voorbeeld wordt er data uit een andere table/model gehaald. De foreign  key moet worden ge-update aan de hand van de rolspelers table.

<?php

// ************************
// * in controller        *
// ************************

// pass rolspeler

$rolspeler = Rolspeler::find()->where(['actief' => '1'])->all();
return $this->render('index', [
     'searchModel' => $searchModel,
     'dataProvider' => $dataProvider,
     'rolspeler' => $rolspeler,
]); 

// fucntion for update (ajax) call from form
  
public function actionUpdateStatus($id, $status, $rolspelerid) {
    $model = $this->findModel($id);
    $model->status=$status;
    $model->rolspelerid=$rolspelerid;
    $model->save();
}

// ************************
// * in view (index)      *
// ************************

// ajax call to update record

<script>
    function changeStatus(id, status, rolspelerid) {
        // console.log(val, id);
        $.ajax({
        url: "<?= Url::to(['update-status']) ?>",
            data: {id: id, 'status': status, 'rolspelerid': rolspelerid },
            cache: false
        }).done(function (html) {
            location.reload();
        });
    }
</script>


// prepare ass. array for the drop down.

<?php $rolspelerList = ArrayHelper::map($rolspeler,'id','naam'); ?>
   
...

<?= GridView::widget([
     'dataProvider' => $dataProvider,
     'filterModel' => $searchModel,
     'columns' => [
       
      // show dropdown and call ajax script that calls the methos/function in teh controller
        
     'format' => 'raw',
         'value' => function ($model) {
             return Html::dropDownList('status', $model->status, ['0'=>'Wachten','1'=>'Loopt','2'=>'Klaar'],
             ['onchange' => "changeStatus('$model->id', $(this).val(), '$model->rolspelerid')"]);
            }],
      
...
