Actions
Once all required fields are present and validated, the actions are performed. These can be completely arbitrary functions that receive the form data and action options as arguments. An example is the builtin email
action. You can create your own action, too, of course!
To add custom actions, create a site/plugins/uniform-actions/uniform-actions.php
file and implement all your custom actions there. Take a look at the email
action to see how to implement one.
