如何在yii2中编写BETWEEN查询

Question

我遇到了问题，我想知道这是否是在yii2中编写BETWEEN查询的正确方法。

在我的控制器代码中，我声明了$to_price，这是我的SearchModel代码，但我总是得到null的{​​{1}}值，以下是我的$this->to_price代码

search model

如果它不是我得不到任何结果但我可以看到生成的命令在 public function search($params) { $query = Events::find(); $dataProvider = new ActiveDataProvider([ 'query' => $query, ]); $this->load($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; } $query->joinWith(['eventsImages']); $query->andFilterWhere([ 'id' => $this->id, 'main_category_id' => $this->main_category_id, 'address' => $this->address, ]); //$to_price = $params->to_price; $query->andFilterWhere(['like', 'title', $this->title]) ->andFilterWhere(['like', 'description', $this->description]) ->andFilterWhere(['between', 'price', $this ->price, $this -> to_price]) ->andFilterWhere(['like', 'image', $this->image]); $command = $query->createCommand();// Created $command works fine in mysql return $dataProvider; //But in $dataProvider it doesnt return any result }

中完美无缺

这里怎么了？

问题在空格$ this - ＆gt; to_price和$ this - ＆gt; price。 它应该是$ this-＆gt; to_price和$ this-＆gt;价格。 因此，在过滤器行代码之间进行更改

->andFilterWhere(['between', 'price', $this ->price, $this -> to_price])

要

->andFilterWhere(['between', 'price', $this->price, $this->to_price])

$ this和 - ＆gt;之后不允许使用空格运营商
