magento 2 - How to create new object Product?

Question

How to create new object Product ?
Example:

$product = new Product();
$product->sku = 'fdfds';
...
$product->save();

Answer 1

Note: This is a quick dirty code, use dependency instead.

Here is example how to create product model object :

<?php 
 $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); manager
 $product = $objectManager->create('\Magento\Catalog\Model\Product');
 $product->setSku('sku'); // Set your sku here
 $product->save();
?>

Another example : You can use it like create a file on root example.php and save the below code:

<?php
use Magento\Framework\App\Bootstrap;
include('app/bootstrap.php');
$bootstrap = Bootstrap::create(BP, $_SERVER);

$objectManager = $bootstrap->getObjectManager();

$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');


$_product = $objectManager->create('Magento\Catalog\Model\Product');
$_product->setName('Test Product');
$_product->setTypeId('simple');
$_product->setAttributeSetId(4);
$_product->setSku('test-SKU');
$_product->save();
?>

Answer 2

It is recommended to use dependency injection rather than directly using object Manager. Example: In your controller file you can use following code :

protected $_product;

public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Catalog\Model\Product $productFactory,
        array $data = []
    ) {
        $this->_product = $productFactory;
        parent::__construct($context, $data);
    }


public function execute()
{
   $this->_product->setSku('test-simple');
    $this->_product->setName('test name simple');
    $this->_product->setAttributeSetId(4);
    $this->_product->setSize_general(193); 
    $this->_product->setStatus(1);
    $this->_product->setTypeId('simple');
    $this->_product->setPrice(10);
    $this->_product->setWebsiteIds(array(1));
    $this->_product->setCategoryIds(array(31));
    $this->_product->setStockData(array(
        'use_config_manage_stock' => 0, 
        'manage_stock' => 1, 
        'min_sale_qty' => 1, 
        'max_sale_qty' => 2, 
        'is_in_stock' => 1, 
        'qty' => 100 
        )
    ); 
    $this->_product->save();
}

Answer 3

This is a very old question, but the selected answer is completly wrong.

The answer from Manashvi Birla is kind of good but it has 2 problems

1. He says he is using factory but infact he is not
2. A product model should not save itself, the respository should do it. I think using save function on product model is even deprecated.

If you wish to use factory on product model class, you will have to do the following

/**
     * SaveProduct constructor.
     * @param \Magento\Catalog\Model\ProductFactory $product
     * @param \Magento\Catalog\Model\ProductRepository $productRepository
     */
    public function __construct(
        \Magento\Catalog\Model\ProductFactory $product,
        \Magento\Catalog\Model\ProductRepository $productRepository
    ) {
        $this->product = $product->create();
        $this->productRepository = $productRepository;
    }

<?php
class SaveProduct
{
    private $product;
    private $productRepository;

    /**
     * SaveProduct constructor.
     * @param \Magento\Catalog\Model\Product $product
     * @param \Magento\Catalog\Model\ProductRepository $productRepository
     */
    public function __construct(
        \Magento\Catalog\Model\Product $product,
        \Magento\Catalog\Model\ProductRepository $productRepository
    ) {
        $this->product = $product;
        $this->productRepository = $productRepository;
    }

    /**
     * @throws \Magento\Framework\Exception\CouldNotSaveException
     * @throws \Magento\Framework\Exception\InputException
     * @throws \Magento\Framework\Exception\StateException
     */
    public function execute(): void
    {
        // example product defination
        $this->product->setSku('test-simple');
        $this->product->setName('test name simple');
        $this->product->setAttributeSetId(4);
        $this->product->setSize_general(193);
        $this->product->setStatus(1);
        $this->product->setTypeId('simple');
        $this->product->setPrice(10);
        $this->product->setWebsiteIds([1]);
        $this->product->setCategoryIds([31]);

        // repository saves product
        $this->productRepository->save($this->product);
    }
}
