Posting a comment to a page

Before reaching the part where we send and process an HTTP request, we have to provide a user interface to create a comment. We will add a form just below the title and description of the page in frontend/tpl/pages.html:

<form enctype="multipart/form-data" method="post">
  <h3>Add a comment for this page</h3>
  {{#if error && error != ''}}
    <div class="error">{{error}}</div>
  {{/if}}
  {{#if success && success != ''}}
    <div class="success">{{{success}}}</div>
  {{/if}}
  <label for="text">Text</label>
  <textarea value="{{text}}"></textarea>
  <input type="button" value="Post" on-click="add-comment" />
</form>

The event that is dispatched after clicking on the button is add-comment. The Pages controller should handle it and fire a request to the backend.

If you stop and think a bit about how the comments look, you will notice that they are similar to the regular user...
