In order for Weever to properly thread comments, it needs to know each comment’s “parent”. You need to pass that information to Weever in the comment form by including a hidden variable within the <form></form> tags:
<input type="hidden" value="[parent’s comment_id goes here]” name="weever-parent-id" />
If the value of the weever-parent-id field is empty or zero, Weever places the submitted comment at the root of the thread.
How do you get the parent’s ID into the hiddne variable? There are two possible methods. The first is to include a “Reply to this comment” link with each comment. You might create it like this:
<a href="/blog/comment-form/{comment_id}/">Reply to this comment</a>
Then create a “comment-form” template that includes the form, along with the hidden variable:
<input type="hidden" value="{segment_3}" name="weever-parent-id" />
The second—and more dynamic—method involves the use of javascript. There are many possibilities for how this might work. In short, the weever-parent-id field would be set dynamically using javascript, and thus the user would never have to leave the current page.
Look for examples of using both of these methods in the Tutorials section.
Weever allows each comment to have a title (or subject). To allow users to add a comment, simply include an input form with the name attribute of “title”, like:
<input type="text" name="title" />
