Controller layer:
adding data:
public function actionAdd(){
$name= Yii::$app->request->post("name");
$content =Yii::$app->request->post("content");
$res=Yii::$app->db->createCommand("insert into yi(name,content) value('$name','$content')")->execute();
return $this->redirect(['ha/show']);
}
Display data:
public function actionShow(){
header("content-type:text/html;charset=utf-8");
$data= Yii::$app->db->createCommand("select * from yi")->queryAll();
return $this->render('show',['data'=>$data]);
}
delete data:
public function actionDel(){
$id= Yii::$app->request->get('id');
$del= Yii::$app->db->createCommand("delete from yi where id = '$id'")->execute();
return $this->redirect(['ha/show']);
}
change the data:
public function actionFind(){
header("content-type:text/html;charset=utf-8");
$id= Yii::$app->request->get('id');
$data = yii::$app->db->createCommand("select * from yi where id ='$id'")->queryAll();
$res=$data[0];
return $this->render('upl',['res'=>$res]);
}
public function actionUpload(){
$id = Yii::$app->request->post('id');
$name = Yii::$app->request->post('name');
$content = Yii::$app->request->post('content');
Yii::$app->db->createCommand("update yi set name='$name',content='$content' where id = '$id'")->execute();
return $this->redirect(['ha/show']);
