Frage

I want to apply coupon code programmatically when the condition is true. If condition false coupon code should be not applied.

Please help me.

Lösung

You can try this below code :

Construct Method :

protected $cart;

public function __construct(
  \Magento\Checkout\Model\Cart $cart
){
   $this->cart = $cart;
}

Then, you can use this below code in your function :

$cart = $this->cart;
$couponCode = 'your_coupon_code';
if(condition true)
{
    $quote = $cart->getQuote()->setCouponCode($couponCode)->collectTotals()->save();
} else {
    $quote = $cart->getQuote()->setCouponCode('')->collectTotals()->save();
}

Object Manager Method :

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$cart = $objectManager->get('\Magento\Checkout\Model\Cart');
$couponCode = 'your_coupon_code';
if(condition true)
{
    $quote = $cart->getQuote()->setCouponCode($couponCode)->collectTotals()->save();
} else {
    $quote = $cart->getQuote()->setCouponCode('')->collectTotals()->save();
}

Note : Use construct method instead of object Manager.
