Custom plugin for HTML feedback form that emails (OJS3)

Hi all,

We’re trying to set up a simple HTML form, somewhere in OJS, maybe on a static page, that allows any user to enter information and when it submits, it triggers the backend to send an email to some recipients.

I’m pretty new to writing plugins for OJS3/2, and I’m wondering if there’s any tutorial/guide on doing so. After googling, I found examples and forum posts, but not much else.

I’ve done Theme before, but I’m not sure where to add the backend PHP code that uses OJS’s emailing libraries.

Thanks for any help you can give!
