Magento 2 : How to get download link of downloadable product in product detail page

Question

I would like to create a download link to the uploaded file on a downloadable product.

All downloadables do not have price and customers do not need to purchase them

Replace Add To Cart button with Download(clicking on download button will download file directly)

Answer 1

You may need to write a custom module to achieve what you are trying to do.

Below is a rough approach to doing that.

• Override the product template file and check whether the product type is downloadable and the price is 0. Based on the condition, hide the add to cart button and add a custom button labeling "Download" or whatever you like.
• On clicking on the custom button, send an ajax request to your custom controller action.
• In the custom controller action, place order programmatically, so that you can get the downloadable link for the purchase in the response.
• Redirect user to the response link to allow the user to download the product.

Note: Above steps are required because, in Magento, there is no direct provision to allow product download directly.
