Does anyone know how to make a product with not fixed price?

By default the product price is $1. But it can be changed by user dragging a price product slider (the product is a donation product).

So how to implement that? How to give an ability for the user to change the product price?

I was thinking about the configurable product with attribute set but I'm not sure that it's really elegant way to do so.

Thank you in advance!

The easiest way I can think of is to create a product in magento to use as a template.

Then create a observer


Then in your observer method you does something like this:

public function updatePrice($observer) {
    $event = $observer->getEvent();
    $quote_item = $event->getQuoteItem();
    $new_price = <insert logic to check if this is the custom product and to get value from ajax>

(note that a user could always fake the post and change the item price)

See Customize Magento using Event/Observer


I would use a custom option for that, with 100(?) options, each in 1$ steps (or maybe higher steps later).

Than you can implement a slider, write some JS to change the select box for the custom option, hide it and finished.

  • Is it really elegant solution if I need $10 000 maximum price? I don't think so that creating 10 000 options would be great idea. Commented Sep 25, 2014 at 19:06
