I'm designing an intake form in InDesign which will be exported as an interactive PDF. I'd like users to be able to click a button on the form to attach files when filling it out. There would be several instances of this and the attachments may include PNGs, Excel spreadsheets, and/or Word docs.
It appears there may be a script that can be added on the Acrobat end, but it would greatly simplify the project flow if I could add this capability within InDesign prior to exporting it as an interactive PDF.

Why bother with a PDF? If it needs to be sent back via email, you're far better off just using an HTML form on website.
Even if you could do this with a PDF form, it would, as Steve says, need to be done in Acrobat and would likely only work with Acrobat, not third party readers or browsers.
