Question

我是php的初学者。这是功能：

public function actionGetreport() {
    $date=$_POST['daterange'];
    $daterange=explode("to",$date);
    $name=$_POST['name'];
    //print_r($name);die();
    $connection = Yii::$app->getDb();
    $command = $connection->createCommand($name)->where(
        ['between', 'InsertedDate', $daterange[0], $daterange[1]]
    );
    //filter||and

    $Result = $command->queryall();
    print_r($Result);die();         
}

在这里，$name有选择查询，我想使用该查询来获取日期范围之间的信息。我得到的错误如下：

Exception 'yii\base\UnknownMethodException' with message 'Calling unknown method: yii\db\Command::where()' 

in D:\xampp\htdocs\oms\vendor\yiisoft\yii2\base\Component.php:294

您可以使用以下简单命令

将以下代码添加到控制器操作

$date = $_POST['daterange'];
$daterange = explode("to",$date);
$name = $_POST['name'];

$data = (new \yii\db\Query())
    ->select($name)
    ->from('YOUR_TABLE_NAME')
    ->where(['>', start_date', $daterange[0] ])
    ->where(['<', start_date', $daterange[1] ])
    ->all();

print_r($data)

在PHP中查询之间执行
