How to add a custom content part to Order Content Type, please?

Hi @sarahelsaig ,
Can you tell me How to add a custom content part to Order Content Type, please? I hope it can be edited in Checkout.cshtml.
Thanks!

You can add a custom content part to the content type definition as usual for Orchard Core, but I don't think you can edit them in the Checkout.cshtml.

We'd probably need something that handled OrderPart.AdditionalData the same way Address.AdditionalFields is used, e.g. here.

Hi @sarahelsaig ,

I add follow codes to Checkout.cshtml, but Inputed data don't save to database.

`

<shape type="InputRow"
prop-Name="@($"{nameof(OrderPart)}.AdditionalData.ExpiredTime")"
prop-Text="@t["Expired Time"]"
prop-Value="@orderPart.AdditionalData.GetMaybe("ExpiredTime")" />

`

Yeah, like I said you can't do that from Checkout.cshtml. The driver currently only looks for content fields in OrderPart.

Hi @sarahelsaig ,
If Checkout.cshtml can't add data to OrderPart.AdditionalData, are there any other ways to add custom fields to Order or OrderPart?

You can alter the Order content item once it's created after checkout, and IPaymentProvider implementations can edit it as well. StripePaymentProvider does something similar to update the Order.StripePaymentPart (e.g. here) which contains transaction IDs coming from Stripe's payment GUI on the checkout screen.

It could be useful to add a similar checkout shape provider (like the Checkout*.cshtml files, but for other forms) that's not tied to payment providers. Feel free to open a feature request issue for that.
