yii2中a连接用post方法请求action却执行了三遍
现在情况是,我点了一下a
链接,是 post
请求,参数是 get
传递的, actionTripDays
方法执行了三遍,表里被插入了三条数据,应该只执行一次,插入一条数据的,这是为毛呢??求帮助
但我在,if
里,dump($position)
却只有一次输出。
<code><a href="<?=%20Url::toRoute(%5B'trip-days',%20'id'%20=>%20%24logId,%20'position'%20=>%20'end'%5D)%20?>" class="add-one-day" data-method="post" rel="nofollow">+ 新增后一天</a> public function actionTripDays($id) { $model = $this->findModel($id); // 最开始是这样写的,执行了两遍 if (!empty($position = Yii::$app->request->get('position', ''))) // 变成下面这样干脆执行了三遍 if (Yii::$app->request->getIsPost() && !empty($position = Yii::$app->request->get('position', ''))) { // dump(Yii::$app->request->get('position', '')); // exit; TravelDay::addDay($position, $model->id); } else { TravelDay::initDay($model->id); } $days = TravelDay::find() ->where(['travel_log_id' => $model->id]) ->orderBy(['order' => SORT_ASC]) ->all(); $images = TravelImg::find() ->where(['travel_log_id' => $model->id]) ->orderBy(['order' => SORT_ASC]) ->all(); return $this->render('trip-days', [ 'images' => $images, 'days' => $days, 'logId' => $model->id, ]); }</code>
