insert product into forms

Hi,

We want to know if it is possible to insert some product into a RSFormsPro form, to sell items when the subscribe to an event.

Hi,

The solution will probably be to add the "add to cart" link of your product into your form, then your customer will be able to directly add this product into his cart through your "RSFormsPro form".
Note that you'll find your "add to cart" link through the add to cart HTML Link button of your product configuration page.

we want to do one single payment and the form has also a payment function. Can we 'add' products to an order, validate the order after paymant en let hikashop sent the emails?

Hi,

I want to say that everything is possible but it will require some customization of custom development.
You can have a checkout system in HikaShop without payment method, the order will be automatically validated.
You can also use a "simple" payment method like "collect on delivery" which just validate the order to a configured order status.

Regards,
