I want to add remark input text field in checkout page I follow Magento 2 - Set custom attribute value on cart page to set custom attribute in quote_item.

In configurable.phtml

    <div class="field configurable required">
        <div class="control">
            <input type="text" name="remark" id="remark">

In catalog_attribute.xml

<group name="quote_item">
    <attribute name="remark"/>

In SalesQuoteItemSetCustomAttribute

public function execute(\Magento\Framework\Event\Observer $observer)
    $product = $observer->getProduct();
    $quoteItem = $observer->getQuoteItem();

But $product->getRemark() is null, inside /checkout/cart/add/ do I need to set remark in product directly from http request?

Set the product attribute directly to $quoteItem. You don't have to set it manually.

Have a look inside $quoteItem->getData('remark') it should be already there.


Instead of using a magic method, try accessing the value through getData().
