Description

This is a Virtuemart 2 plugin that lets the user add a custom amount to the price of a product, or lets the user completely give the amount they want to pay for a product. It will display an input box for the amount next to the "Add to Cart" button:

donation - productdetails

Typical use cases are:

  • Sell vouchers where the buyer determines the amount
  • Let users add a custom donation amount the product's price
  • Let a user completely define the price of a product

The plugin configuration also allows to specify an upper and/or lower limit for the amount to be added to the price. If the user enters an amount outside this range, the limit will be used instead and a warning message printed.

The amount added to the price will not be handled or displayed separately from the product price, but will directly change the product's price. In particular, it will get the same tax as the original base price of the product.

Configuration & How the plugin works

First, install the plugin with Joomla's extension manager. It will automatically be enabled.

Now, set up a Custom Field ("Products" -> "Custom Fields"):

  • Create a new field (the green + button in the top right corner)
  • Select "Plug-ins" as Custom Field Type
  • Enter the title (will be shown in front of the price input box)
  • Set "Cart Attribute" to "Yes"
  • Select "VM Name the Price" as the plugin

donation - customfield setup

Now you can add this custom field to any product you like:

  • Open the product in the VirtueMart backend, go to the "Custom Fields" tab and add the field you just created. There you can also add a maximum or minimum value allowed for the added amount. In particular, the default lower value of 0.0 prohibits entering discounts. If you remove the lower bound, the user can also enter a negative value and thus reduce the price. If the user enters a price modifier (donation) that is outside the allowed range, the closest value inside the range will be used (e.g. if the upper bound is 100 and the user enters 9999, a value of 100 will be added). VirtueMart 3.x will also print a warning in this case (VM 2 did not provide any way to print such a warning).
  • To sell a product with a fixed price and an optional additional donation, simply set the price for the product and add this custom field.
  • To let the user completely specify the price of a product, set the product's price to 0.00001 (not 0, since then no "Add to cart" button will be displayed!) and add this custom field.
  • donation - customfield product
  • The product page will now display an entry box, where the user can enter the donation amount they want to add to the product price:
  • donation - productdetails
  • The cart (and the order confirmation and the invoice) will also display the donation amount that the user entered:
  • donation - cart
