Search AutoComplete: Magento 2 Module Add All Category for Search

This article is all about how we can develop a Search AutoComplete extension in Magento 2. This module also provides the options to enable category search facilities.

When you install this module this automatically created a div box on the left side of the Magento 2 catalog search box in the header content and then you can select a category from the dropdown and search the product based on category.

Wishusucess Search AutoComplete

 

Step 1:

app/code/Wishusucess/SearchAutocomplete/registration.php

<?php
/*
Author: Wishusucess
Developer: Hemant Singh
Website URL: http://www.wishusucess.com/
*/
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Wishusucess_SearchAutocomplete',
__DIR__
);

 

Step 2:

app/code/Wishusucess/SearchAutocomplete/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Wishusucess_SearchAutocomplete" setup_version="1.0.0">
</module>
</config>

 

Step 3:

app/code/Wishusucess/SearchAutocomplete/frontend/routes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
<router id="standard">
<route id="searchautocomplete" frontName="searchautocomplete">
<module name="Wishusucess_SearchAutocomplete" />
</route>
</router>
</config>

 

Step 4: Magento 2 Search AutoComplete Controller

 

app/code/Wishusucess/SearchAutocomplete/Controller/Index/Index.php

<?php
/*
Author: Wishusucess
Developer: Hemant Singh
Website URL: http://www.wishusucess.com/
*/
namespace Wishusucess\SearchAutocomplete\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action
{
protected $_resultJsonFactory; 
protected $_productCollectionFactory;
protected $_reviewFactory;
protected $_storeManager;
protected $_imageBuilder;
protected $_productVisibility;
protected $_categoryFactory;
protected $_priceHelper;

public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Framework\Controller\Result\JsonFactory $resultJsonFactory,
\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,
\Magento\Review\Model\ReviewFactory $reviewFactory,
\Magento\Store\Model\StoreManagerInterface $storeManager,
\Magento\Catalog\Block\Product\ImageBuilder $imageBuilder,
\Magento\Catalog\Model\Product\Visibility $productVisibility,
\Magento\Catalog\Model\CategoryFactory $categoryFactory,
\Magento\Framework\Pricing\Helper\Data $priceHelper)
{
$this->_resultJsonFactory = $resultJsonFactory;
$this->_productCollectionFactory = $productCollectionFactory;
$this->_reviewFactory = $reviewFactory;
$this->_storeManager = $storeManager;
$this->_imageBuilder = $imageBuilder;
$this->_productVisibility = $productVisibility;
$this->_categoryFactory = $categoryFactory;
$this->_priceHelper = $priceHelper;
parent::__construct($context);
}
public function execute()
{
$postMessage = $this->getRequest()->getPost();

$query = preg_replace('/[^A-Za-z0-9\ \_\'\-]/', '', $postMessage['query']);
$category = preg_replace('/[^a-z0-9]/', '', $postMessage['category']);


if($category=='all'){
$collection = $this->_productCollectionFactory->create()
->addAttributeToSelect('*')
->addAttributeToFilter('name', array('like'=>'%'.$query.'%'));
}else{
$collection = $this->getProductCollection($category);
$collection->addAttributeToFilter('name', array('like'=>'%'.$query.'%'));
}
$collection->setVisibility($this->_productVisibility->getVisibleInSiteIds());

$collection ->setPageSize(5)
->setCurPage(1);

$productList = [];
$i = 1;

foreach ($collection as $product) {
$productList[$i]['name'] = str_ireplace($query,'<b>'.$query.'</b>',$product->getName());
$productList[$i]['price'] = $this->_priceHelper->currency(number_format($product->getFinalPrice(),2),true,false);
$productList[$i]['url'] = $product->getProductUrl();
$productList[$i]['thumbnail'] = $this->getImage($product, 'category_page_list')->getImageUrl();
$this->_reviewFactory->create()->getEntitySummary($product, $this->_storeManager->getStore()->getId());
$productList[$i]['rating'] = $product->getRatingSummary()->getRatingSummary();
$i++;
}

if($collection->getSize() > 0){
return $this->_resultJsonFactory->create()->setData($productList);
}else{
return $this->_resultJsonFactory->create()->setData([]);
}
}
public function getImage($product, $imageId)
{
return $this->_imageBuilder->setProduct($product)
->setImageId($imageId)
->create();
}
public function getCategory($categoryId)
{
$category = $this->_categoryFactory->create()->load($categoryId);
return $category;
}
public function getProductCollection($categoryId)
{
return $this->getCategory($categoryId)->getProductCollection()->addAttributeToSelect('*'); 
}
}

 

Step 5: Create Block for Search AutoComplete

app/code/Wishusucess/SearchAutocomplete/Block/SearchAutocomplete.php

<?php
/*
Author: Wishusucess
Developer: Hemant Singh
Website URL: http://www.wishusucess.com/
*/
namespace Wishusucess\SearchAutocomplete\Block;
class SearchAutocomplete extends \Magento\Framework\View\Element\Template
{
protected $_categoryCollectionFactory;
protected $_storeManager;
protected $_store;
protected $_categoryRepository;

public function __construct(
\Magento\Backend\Block\Template\Context $context, 
\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $categoryCollectionFactory,
\Magento\Store\Model\StoreManagerInterface $storeManager,
\Magento\Store\Model\Store $store,
\Magento\Catalog\Model\CategoryRepository $categoryRepository,
array $data = []
)
{
$this->_categoryCollectionFactory = $categoryCollectionFactory;
$this->_storeManager = $storeManager;
$this->_store = $store;
$this->_categoryRepository = $categoryRepository;
parent::__construct($context, $data);
}

public function getCategoryCollection($isActive = true, $level = false, $sortBy = false, $pageSize = false)
{
$collection = $this->_categoryCollectionFactory->create();
$collection->addAttributeToSelect('*');
if ($isActive) {
$collection->addIsActiveFilter();
}
if ($level) {
$collection->addLevelFilter($level);
}
if ($sortBy) {
$collection->addOrderField($sortBy);
}
if ($pageSize) {
$collection->setPageSize($pageSize); 
}
$collection->setOrder('position', 'ASC');
return $collection;
}
public function getAjaxUrl(){
return $this->_storeManager->getStore()->getUrl('searchautocomplete/index/index');
}
public function getMediaUrl(){
return $this ->_storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA );
}
public function getRootCategoryId()
{
return $this->_store->getStoreRootCategoryId();
}
public function getCategories(){
return $this->_categoryRepository->get(2)->getChildrenCategories();
}
}

 

Step 6:

app/code/Wishusucess/SearchAutocomplete/view/frontend/layout/default.xml

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd" >
<body>
<referenceContainer name="header-wrapper">
<referenceBlock name="top.search" remove="true"/>
<block class="Magento\Framework\View\Element\Template" name="top.search" as="" template="Magento_Search::form.mini.phtml" />
<block class="Wishusucess\SearchAutocomplete\Block\SearchAutocomplete" name="search.autocomplete" after="logo" template="search/autocomplete.phtml" />
</referenceContainer>
</body>
</page>

 

Step 7:

app/code/Wishusucess/SearchAutocomplete/templates/search/autocomplete.phtml
