【问题描述】:
我在 MySQL 数据库的基本模板中使用 yii2
为什么此代码返回一个对象,而不是从数据库中选择的记录数组
当我使用 var_damp($rooms) 时,输出似乎是一个对象,而不是数组格式的选定记录数组;
任何机构都可以提供帮助
public function actionIndexFiltered()
{
$query = Room::find();
$searchFilter = [
'floor' => ['operator' => '', 'value' => ''],
'room_number' => ['operator' => '', 'value' => ''],
'price_per_day' => ['operator' => '', 'value' => ''],
];
if(isset($_POST['SearchFilter']))
{
$fieldsList = ['floor', 'room_number', 'price_per_day'];
foreach($fieldsList as $field)
{
$fieldOperator = $_POST['SearchFilter'][$field]['operator'];
$fieldValue = $_POST['SearchFilter'][$field]['value'];
$searchFilter[$field] = ['operator' => $fieldOperator, 'value' => $fieldValue];
if( $fieldValue != '' )
{
$temp1=$query->andWhere([$fieldOperator, $field, $fieldValue]);
}
}
}
$room1=$temp1->all();
$rooms = $query;
return $this->render('indexFiltered', [ 'rooms' => $rooms, 'searchFilter' => $searchFilter,'room1'=>$room1 ]);
}
输出是这样的,这表明此代码返回一个查询对象,而不是数据库上的查询执行数组, 所以我使用 var_dump 函数检查了代码,结果是它返回的是一个对象而不是数组
