Filter copy parameters in URL - php

Question

I create filter form for my data using data provider and search model and have a problem, when my filter parameters copy in url when I click submit button more than one time.
Model's ApartmentsSearch search method:
public function search($params)
{
$query = Apartments::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
if (!($this->load($params) && $this->validate())) {
return $dataProvider;
}
$query->andFilterWhere([
'rooms' => $this->rooms,
]);
return $dataProvider;
}
Controller actionIndex method:
public function actionIndex()
{
$searchModel = new ApartmentsSearch();
$dataProvider = $searchModel->search(Yii::$app->request->get());
return $this->render('index', [
'dataProvider' => $dataProvider,
'searchModel' => $searchModel,
]);
}
View with ListView widget:
<?= $this->render('_filter', ['searchModel' => $searchModel]); ?>
<?= ListView::widget([
'dataProvider' => $dataProvider,
'itemView' => '_list',
'options' => [
'tag' => 'div',
'class' => 'apartments-list',
],
'layout' => '{summary}{items}{pager}',
'summary' => 'Показано квартири: <b>{begin}-{end}</b> з <b>{totalCount}</b>.',
'summaryOptions' => [
'tag' => 'div',
'class' => 'summary',
],
'itemOptions' => [
'tag' => 'div',
'class' => 'apartment-item',
],
]); ?>
And _filter.php view with form:
<?php $form = ActiveForm::begin([
'method' => 'get',
]); ?>
<?= $form->field($searchModel, 'rooms') ?>
<div class="form-group">
<?= Html::submitButton('Search', ['class' => 'btn btn-primary']) ?>
<?= Html::resetButton('Reset', ['class' => 'btn btn-default']) ?>
</div>
<?php ActiveForm::end(); ?>
So, when I input any number in field and click submit I see url like this:
http://localhost/?ApartmentsSearch[rooms]=2
When I click second time I see url with copied parameter:
http://localhost/?ApartmentsSearch[rooms]=2&ApartmentsSearch[rooms]=2
I don't want copy parameters in url, I need to change value of any parameter.
Can you help me?

Solved.
In active form I forgot add action property:
<?php $form = ActiveForm::begin([
'action' => ['index'],
'method' => 'get',
]); ?>
<?= $form->field($searchModel, 'rooms') ?>
<div class="form-group">
<?= Html::submitButton('Search', ['class' => 'btn btn-primary']) ?>
<?= Html::resetButton('Reset', ['class' => 'btn btn-default']) ?>
</div>
<?php ActiveForm::end(); ?>
