I have a custom input on the product view page just below the options. This is visible for all products.

I want to show the contents of that input on the cart page in the list of product variants, shown below:


I know I could create a product option but I don't want to have to apply this option to every single product individually.

Is there a way to get this done and if so, how would I go about it?

If anyone needs any more information, please let me know.

Here is the good example how to do this:

Four Ways to Customize a Cart Item

Or Create a new module and Add Following Event in Config.xml


In Observer.php add following Method

   public function salesQuoteAddressCollectTotalsBefore($observer)
        $quote = $observer->getQuote();
        $quote_items = $quote->getItemsCollection();
        foreach ($quote_items as $item) {
            $additionalOptions = array(
                    'code'  => 'my_code',
                    'label' => 'This text is displayed through additional options',
                    'value' => 'ID is ' . $item->getProductId() . ' and SKU is ' . $item->getSku()
                     'code'  => 'additional_options',
                     'value' => serialize($additionalOptions),

  • Thank you for your answer. I may not have been completely clear in my question but each item will have different text. The methods you have provided seem to change all of the items in the cart. I only want to change the one that is currently being added. – Wildcard27 May 27 '16 at 4:53
