Yii2 basic mode do not call main.php - php

Question

I use basic mode on Yii2 framework. I create two controllers - SiteController and CategoryController. I have two folders with few views - site (index and about) and category (category and search).
When i render view by SiteController evething is ok, but when i render view by CategoryController actionSearch - do not call main.php and do not show any html in view, but if i call die - the results is there.
Here is a code:
model:
namespace app\models;
use yii\db\ActiveRecord;
class Categories extends ActiveRecord
{
public static function tableName()
{
return 'categories';
}
public function getProducts(){
return $this->hasMany(Products::className(), ['category_id' => 'id']);
}
}
and CategoryController:
public function actionSrch() {
$cat = Categories::findOne(1);
$q = Yii::$app->request->get('q');
if(isset($q) and $q!=''){
$query = Products::find()->where(['like', 'title', $q]);
// pagination
$pages = new Pagination([
'totalCount' => $query->count(),
'pageSize' => 4,
'forcePageParam' => false,
'pageSizeParam' => false ]);
$products = $query->offset($pages->offset)->limit($pages->limit)->all();
}else{
$products = Products::find()->where('title<>:title', [':title'=>''])->all();
}
$this->render('search', compact('products','pages', 'q', 'cat'));
}
and the Search form:
<div class="col-sm-3">
<div class="search_box pull-right">
<form action="<?= \yii\helpers\Url::to(['categories/search']) ?>" method="get">
<input type="text" placeholder="Search" name="aaa">
</form>
</div>
</div>
and the view in search.php
use yii\helpers\Html;
use yii\helpers\Url;
use yii\widgets\LinkPager;
<ul class="catalog category-products">
<?= \app\components\MenuWidget::Widget(['tpl' => 'menu']) ?>
</ul>
<div class="col-sm-9 padding-right">
<div class="features_items"><!--features_items-->
<?php if(!empty($products)): ?>
<?php $i = 0; foreach($products as $prd): ?>
<h2><?= $prd->price ?></h2>
<?php endif; ?>
<?php endforeach; ?>
<?php else :?>
<div class="alert alert-danger">Do not have products!!!</div>
<?php endif; ?>

First chack your action name actionSrch or actionSearch.
And add return before render file like below.
public function actionSrch() {
$cat = Categories::findOne(1);
$q = Yii::$app->request->get('q');
if(isset($q) and $q!=''){
$query = Products::find()->where(['like', 'title', $q]);
// pagination
$pages = new Pagination([
'totalCount' => $query->count(),
'pageSize' => 4,
'forcePageParam' => false,
'pageSizeParam' => false
]);
$products = $query->offset($pages->offset)->limit($pages->limit)->all();
}else{
$products = Products::find()->where('title<>:title', [':title'=>''])->all();
}
return $this->render('search', compact('products','pages', 'q', 'cat'));
}
