Magento 2 : Add product to cart programmatically with custom price

Question

I want to add product with custom price in cart/checkout only but the original price of product should not get any affect.

So far I've achieved this.I'm adding product programmatically based on some condition. Not using any observer or something I'm just passing product id to my custom controller and adding that product into cart.

public function execute(){
 ....
 $productObj->setData('_edit_mode', true);
 $productObj->setPrice(8000);
 $productObj->setFinalPrice(8000);
 $productObj->save();
 $this->cart->addProduct($productObj, $product);
 ....
 $this->cart->save();
}

Using above function only product original price get changed but not in cart so what can be done to do so?

Answer 1

I've resolved by following

public function execute(){
 ....
 $finalPrice = $totalQty * $product->getKrat() * $price;
 $item->setCustomPrice($product->getKrat() * $price);
 $item->setOriginalCustomPrice($finalPrice);
 $item->getProduct()->setIsSuperMode(true);
 $item->setQty(0);
 $item->save();
}

• Nagaraju Kasa: hi kaushal please let me know how can use $item in my controller
• Kaushal Suthar: @NAGARAJUKASA: $item = $observer->getEvent()->getQuoteItem()
• Nagaraju Kasa: i am adding the product to cart from the custom controller but u have given the observer code. please suggest me.
• manini: @NagarajuKasa Did you manage to do the same using controller?
• Nagaraju Kasa: @manini yes manini we can able to add a product through controller. but please confirm me whether you want to add same product price or custom price?
