This plugin is a developer’s toolkit for collecting form data from your WordPress site. It provides the necessary hooks and utilities for you to manage how data is stored and displayed later.
The best way to get started is to look at example-functions.php and example.php in <code>/plugins/form-data-collector/example</code> folder.
You can see a list of utilities and hooks <a href="https://github.com/taunoha/form-data-collector/wiki/" rel="nofollow ugc">here</a>.
Not compatible with 1.x.x versions 🙁
