Magento 2 – Get Category Collection From Product ID

categorycollection;magento2

How can I get category collection data from product ID? I have tried using the following way but it's not working for me.

$product = $this->_productFactory->create()->getCollection()->load($pid);
$cats = $product->getCategoryIds();
if(count($cats) ){
    $firstCategoryId = $cats[0];
    $_category = $this->_categoryFactory->create()->getCollection()->load($firstCategoryId);
    return $_category->getName();
}

    return $_category->getName();
}

Instead of store filter, try with root category filter.

$rootcatID = Mage::app()->getStore()->getRootCategoryId();

$productCollection = Mage::getResourceModel('catalog/product_collection')
->joinField('category_id','catalog/category_product','category_id','product_id=entity_id',null,'left')
->addAttributeToFilter('category_id', array('in' => $rootcatID))
->addAttributeToSelect('*');

$productCollection->load();

Magento – How to get first item from product collection

To get the first item in a collection simply use the getFirstItem() function on the collection.

Example:

// this gets all the products
$productCollection = Mage::getResourceModel('catalog/products_collection');
// this line gets just the first product
$firstItem = $productCollection->getFirstItem();

Example 2 (for this particular question):

$_category  = $this->getCurrentCategory();
$_collection = $_category->getProductCollection();
$_product =  $_collection->getFirstItem(); // this will get first item in collection

Some other areas this can be used:

Customers

$customerCollection = Mage::getResourceModel('customer/customer_collection');
$firstCustomer = $customerCollection->getFirstItem();

Orders

$orderCollection = Mage::getResourceModel('sales/order_collection');
$firstOrder = $orderCollection->getFirstItem();

Please Note:

Its not a good idea to load ALL the products/customers/orders for this takes a lot of resources. The preferred way is to limit what you want to load by using the addAttributeToFilter() or addFieldToFilter() functions, see example below:

$productCollection = Mage::getResourceModel('catalog/product_collection')
                           ->addAttributeToFilter('sku', 'book123`);
