Spiral Unpaid Download for Virtuemart
This custom field plugin for Joomla and Virtuemart allows you to add a free download link to your product page. For example if you want your customers to be able to download a free pdf manual for your product you can use this plugin to attach a download button to the page.
The plugin can track the number of downloads made.
It has some useful additional options. Optionally you can require that the customer is logged in before making a download, or belongs to a specific shopper group. So the plugin could be used for a site where the customer buys a subscription which allows him/her to make downloads from the site.
You can have as many download fields as you want per product.
Please note that the free download plugin is not designed to create a link which will be sent in an order email when an order is confirmed.
