Make Dynamic action-xhr in amp-form

[ankur0890]

It would be really good if we can bind action-xhr in the amp-form.

Scenario:

Got two forms: Contact Form and OTP (intial hidden)
Contact form successful submission sends some dynamic response (using amp-bind preserve the response state) which is used to create OTP form url.

Let me know what you think of this?

Shouldn't be too difficult to enable with bind. We already allow amp-list URLs to be bound with [src].

This isn't currently on the mid-term roadmap. Would be useful for our prioritization to hear any business impact that might not be obvious to us. Thanks!

Gotcha - thanks.
Our app (https://shopsheriff.com/amp) converts Shopify stores into AMP pages. The "Add to Cart" button submits a GET request to a specific Shopify store URL in order to perform that adding-to-cart functionality. There are some other functionality that may take place such as skipping the cart, and these require different URLs to be submitted. That was my use case. Fortunately I've found a way around this by using a different method, so I'm not currently in need of it, but that was a pretty decent use-case, because I had to interact with form functionality and url structures that were pre-determined.

Thanks for sharing! Good to know the concrete need here

Another workaround is to use multiple forms and buttons.
