Buttons

//Cancel

<?= Html::a('Cancel', ['index'], ['class'=>'btn btn-primary']) ?>

//Delete
<?= Html::a('Delete', ['delete', 'id' => $model->id], [
            'class' => 'btn btn-danger',
            'data' => [
                'confirm' => 'Are you sure you want to delete this item?',
                'method' => 'post',
            ],
        ]) ?>

 

Active Records

Insert update delete

// INSERT (table name, column values)
Yii::$app->db->createCommand()->insert('user', [
    'name' => 'Sam',
    'age' => 30,
])->execute();

// INSERT via raw Query
$sql="insert into examen_gesprek_soort (examen_id, gesprek_soort_id) values(:examenid, :gesprekid)";
$params = array(':examenid'=> $id, ':gesprekid' => $value );
$result = Yii::$app->db->createCommand($sql)->bindValues($params)->execute();

// UPDATE (table name, column values, condition)
Yii::$app->db->createCommand()->update('user', ['status' => 1], 'age > 30')->execute();

// DELETE (table name, condition)
Yii::$app->db->createCommand()->delete('user', 'status = 0')->execute();

In Controller, get data from arbitrary model;

use app\models\Examen;

$examen = examen::find()->where(['actief' => '1'])->orderBy(['datum_van' => 'SORT_DESC'])->one();

$examen = examen::find()->where(['actief' => '1'])->orderBy(['datum_van' => 'SORT_DESC'])->all();

$gesprekSoort = gesprekSoort::find()->all();

$gesprekSoort = examenGesprekSoort::findAll(['examen_id' => $id]);

$sql="delete from examen_gesprek_soort where examen_id = :examenid";
$params = array(':examenid'=> $id);
$result = Yii::$app->db->createCommand($sql)->bindValues($params)->execute();

$sql="insert into examen_gesprek_soort (examen_id, gesprek_soort_id) values(:examenid, :gesprekid)";
$params = array(':examenid'=> $id, ':gesprekid' => $value );
$result = Yii::$app->db->createCommand($sql)->bindValues($params)->execute();

$gesprekken = gesprekSoort::find()->where([])->joinWith('examenGesprekSoorts')->all();
