Filter Products: Get Product Collection By Attribute Filter in Magento 2

In this article, I am going to explain how we can get the product collection or filter products based on custom attributes in Magento 2. In Magento product collection is one of the most important things because product collection is often required in different filters as well as requirements.

So there are multiple names of showing product collections on the frontends in Magento 2.

We can show the products collections on various conditions like on the load conditions on the get conditions on the filter conditions on the sort conditions but here I am going to explain based on filter product collections

  • Filter product collection
  • Load product collection
  • Sort of product collection
  • Get product collection

Magento 2 Attribute Filter Products

Load Filter Products Based on Attributes in Magento 2

In order to get the attribute filter product collections I Magento 2 we have to create the first block and then we can call that function in the template to load the product.

app/codeWishusucess/FilterProducts/registration.php

app/codeWishusucess/FilterProducts/etc/module.xml

app/codeWishusucess/FilterProducts/Block/Filterproducts.php

app/codeWishusucess/FilterProducts/Helper/Data.php

app/codeWishusucess/FilterProducts/view/frontend/templates/filterproducts.phtml

 

Register Filter Product Module

app/codeWishusucess/FilterProducts/registration.php

<?php
/*
* @Author Hemant Singh
* @Developer Hemant Singh
* @Module Wishusucess_FilterProducts
* @copyright Copyright (c) Wishusucess (http://www.wishusucess.com/)
*/
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Wishusucess_FilterProducts',
__DIR__
);

 

Give Basic Information of Module

app/codeWishusucess/FilterProducts/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
<module name="Wishusucess_FilterProducts" setup_version="1.0.0" />
</config>

 

Create Block To Get Filter Products By Attribute

Here you have put the identifier of attributes in the addAttributeToFilter() function and set the visibility.

->addAttributeToSelect($this->catalogConfig->getProductAttributes())
//->addAttributeToFilter('entity_id', array('in'=>$producIds))
->addAttributeToFilter('attribute_identifier', array('in'=>'1')) //Filter Product Attribute Collections
->setVisibility($this->productVisibility->getVisibleInCatalogIds());

Now you can get the attribute filter collections of the products.

app/codeWishusucess/FilterProducts/Block/Filterproducts.php

Create Helper Class For Filter Products

app/codeWishusucess/FilterProducts/Helper/Data.php

<?php
/*
* @Author Hemant Singh
* @Developer Hemant Singh
* @Module Wishusucess_FilterProducts
* @copyright Copyright (c) Wishusucess (http://www.wishusucess.com/)
*/
namespace Wishusucess\FilterProducts\Helper;

class Data extends \Magento\Framework\App\Helper\AbstractHelper {

public function __construct(
\Magento\Framework\App\Helper\Context $context
) {
parent::__construct($context);
}
public function getConfigData($path)
{
$value = $this->scopeConfig->getValue($path, \Magento\Store\Model\ScopeInterface::SCOPE_STORE);
return $value;
}
}

 

Print Attribute Filter Collections Data in Phtml

app/codeWishusucess/FilterProducts/view/frontend/templates/filterproducts.phtml

<?php $_productCollection = $this->getProducts();
$_helper = $this->helper('Magento\Catalog\Helper\Output');
?>

We can use this code to get the product collection in the vew/frontend/templates/filterproducts.phtml files.
