How to Programmatically Add Product to Cart in Magento 2

Sometimes, Magento 2 store admin needs to prefill the shopping cart with a product whenever a user lands to the website. There are many uses of this functionality; for example, the admin may require to add a virtual product to cart whenever a particular product is added to the cart by a customer, the admin may want to give away the free product by default, the admin requires to integrate a custom system or he may require to send visitors directly to the checkout with the product in the cart.

Default Magento 2 doesn’t allow this. So, I’ve come up with a method to programmatically add product to cart in Magento 2.

Method to Programmatically Add Product to Cart in Magento 2:

<?php
namespace Vendor\Extension\Controller\Index;
use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\Data\Form\FormKey;
use Magento\Checkout\Model\Cart;
use Magento\Catalog\Model\Product;
class Post extends Action
{
    protected $formKey;   
    protected $cart;
    protected $product;
    public function __construct(
        Context $context,
        FormKey $formKey,
        Cart $cart,
        Product $product) {
            $this->formKey = $formKey;
            $this->cart = $cart;
            $this->product = $product;      
            parent::__construct($context);
    }
    public function execute()
     { 
        $productId =10;
        $params = array(
                    'form_key' => $this->formKey->getFormKey(),
                    'product' => $productId, 
                    'qty'   =>1
                );              
        $product = $this->product->load($productId);       
        $this->cart->addProduct($product, $params);
        $this->cart->save();
     }
}

<?php

namespace Vendor\Extension\Controller\Index;

use Magento\Framework\App\Action\Action;

use Magento\Framework\App\Action\Context;

use Magento\Framework\Data\Form\FormKey;

use Magento\Checkout\Model\Cart;

use Magento\Catalog\Model\Product;

class Post extends Action

{

protected $formKey;

protected $cart;

protected $product;

public function __construct(

Context $context,

FormKey $formKey,

Cart $cart,

Product $product) {

$this->formKey = $formKey;

$this->cart = $cart;

$this->product = $product;

parent::__construct($context);

}

public function execute()

{

$productId =10;

$params = array(

'form_key' => $this->formKey->getFormKey(),

'product' => $productId,

'qty' =>1

);

$product = $this->product->load($productId);

$this->cart->addProduct($product, $params);

$this->cart->save();

}

  Hi Rajat,
  Our blog is for adding the product to the cart which results in the product added to the cart page.
  but if you want to change in the mini cart, you have to implement the concept of section.xml
