Collections in\u00a0Magento 2\u00a0are used to fetch multiple rows from tables, join tables with primary tables, select specific columns, apply a WHERE clause to query, or apply any conditions.<\/p>\n\n\n\n
A store owner may want to use collections to print order details with header and footer when the number of orders is greater than 0 and for no orders, i.e., 0 orders, display a message \u201cNo record found\u201d without a header and footer.<\/p>\n\n\n\n
In such scenarios, one may need to get Magento 2 collection count.<\/p>\n\n\n\n
Return the total number of items from the collection, i.e., count the collection data using the below solution:<\/p>\n\n\n\n
Here we are using an example of fetching all products and count these all fetched data.<\/p>\n\n\n\n
use Magento\\Catalog\\Model\\ResourceModel\\Product\\CollectionFactory;\n\nprotected $productCollectionFactory;\n\npublic function __construct(CollectionFactory $productCollectionFactory)\n{\n $this->productCollectionFactory = $productCollectionFactory;\n}\n\npublic function getProductCollection()\n{\n $collection = $this->productCollectionFactory->create();\n $collection->addAttributeToSelect('*');\n return $collection;\n}<\/pre>\n\n\n\nWe have got a whole collection of products using the above code, now call the getProductCollection() wherever you want to use the collection.<\/p>\n\n\n\n
$collection = $this->getProductCollection();<\/pre>\n\n\n\nNow the main part, count the items collected in $collection by using the below code.<\/p>\n\n\n\n
$collection->count();<\/pre>\n\n\n\nYou can apply various validations, conditions, or anything according to your requirements using the collection count method.<\/p>\n\n\n\n
