Magento 2 – Product Collection

In day to day life of Magento 2 developer, somewhere in each and every project, a developer needs a product collection. With that regards, In this code snippet post, we will see all the aspect of product collection such as collection, filter, sorting etc.

Note: For the demonstrated purpose we have used Objectmanager.Codextblog never recommend the direct use of ObjectManager.One should always use a constructor method to instant an object.

Product Collection

Load product collection

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');

$collection = $productCollectionFactory->create();
$collection->setPageSize(3);

foreach ($collection as $product) {
    print_r($product->getData());
}

Load product collection with all attribute

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');

$collection = $productCollectionFactory->create();
$collection->addAttributeToSelect('*');
$collection->setPageSize(3);

foreach ($collection as $product) {
    print_r($product->getData());

}

Load product collection with specific attribute

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');

$collection = $productCollectionFactory->create();
$collection->addAttributeToSelect('name');
$collection->addAttributeToSelect('price');
$collection->setPageSize(3);

foreach ($collection as $product) {
    print_r($product->getData());
}

Load product collection by category

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');

$categoryCollectionFactory = $objectManager->get('\Magento\Catalog\Model\CategoryFactory');

$categoryId = '9';
$category = $categoryCollectionFactory->create()->load($categoryId);

$collection = $productCollectionFactory->create();
$collection->addAttributeToSelect('*');
$collection->addCategoryFilter($category);
$collection->addAttributeToFilter('visibility', \Magento\Catalog\Model\Product\Visibility::VISIBILITY_BOTH);
$collection->addAttributeToFilter('status',\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED);

foreach ($collection as $product) {
    print_r($product->getData());
}

Filter Product Collection

Is equal to

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('status', array('eq' => 1));

Is not equal to

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('status', array('neq' => 1));

Greater than

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('price', array('gt' => 50));

Greater than or equal To

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('price', array('gteq' => 50));

Less than

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('price', array('lt' => 50));

Less than or equal To

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('price', array('lteq' => 50));

Like

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('sku', array('like' => '%ABC%'));

Not Like

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('sku', array('nlike' => '%ABC%'));

In Array

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('entity_id', array('in' => array(1,2,3)));

Not In Array

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('entity_id', array('nin' => array(1,2,3)));

NULL

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('description',  array('null' => true));

Not NULL

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToFilter('description',  array('notnull' => true));

Sort Product Collection

Order by Ascending

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->setOrder('price', 'ASC');

Order by Descending

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->setOrder('price', 'DESC');

Limit Product Collection

Limit

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->setPageSize(50)->load();

Limit with current page

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->setPageSize(50)->setCurPage(2)->load();

Count Collection

Count

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
echo $collection->count();

print Collection Query

Print query

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
echo $collection->getSelect()->__toString();
