+# Dynamic Forms in static pages for ![statamic](https://raw.githubusercontent.com/Neophen/statamic-dynamic-token/master/public/statamic-logo.png)
+
+Want static caching in statamic? And still want to have dynamic forms? for e.g.
+
+![dynamic form in static page](https://raw.githubusercontent.com/Neophen/statamic-dynamic-token/master/public/dynamic_in_static.png)
+
+Just add a `{{ dynamic_token }}` to your layout file just before `</body>` tag.
+then add an `APP_URL=site.com` to your `.env` file
+
+### Installing
+Copy the `DynamicToken` into your `site/addons` folder.
+### How does this work?
+First off, if `javascript` is disabled this won't work. We will add this functionality later. On page load it will get a fresh csrf token and update all your forms with it. It will automatically update the token every 15 minutes.
+##### There are two parts:
+###### 1st:
+The `{{ dynamic_token }}` inserts a bit of javascript into your static html file, which allows it to pull a new `csrf` token and update all `<form>` tags which have an `<input name="_token">`, this applies to all `{{ form:create }}` tags, or any form if you add `<input name="_token">` to your normal forms.
+###### 2st:
+A simple controller, note you might need to exclude `/!/DynamicToken` from csrf setting like
+Disable CSRF verification by adding `/!/DynamicToken` to the `csrf_exclude` array in `site/settings/system.yaml`. Don't worry we check that the referrer is comming from your `APP_URL`.
+
+### Gotchas
+If you've changed your api denominator, you will need to modify `$route = '/!/DynamicToken/refresh';` in the `DynamicToken/DynamicTokenTags.php` file. The default statamic denominator is `/!/`;
