How to add an additional field for DLE comments?

Question

JavaScript

Can anyone suggest if it's possible to add an extra "phone" field for DLE comments?
Here is the addcomments.tpl code:

[not-logged]
<input type="text" name="name" id="name" placeholder="Ваше имя" required>
<input type="text" name="mail" id="mail" placeholder="E-mail" required>
<input type="text" name="phone" id="phone" placeholder="Телефон" required>
[/not-logged]
{editor}
<button type="submit" name="submit" id="add_com" class="but">Отправить</button>

A line that's just for show right now, but should work:

<input type="text" name="phone" id="phone" placeholder="Телефон" required>

I couldn't find anything on the net about this topic, I would be very grateful if anyone can help!

Answer 1

I don’t quite understand what kind of “toy” we are talking about, if you mean classic gamedev, then the second option is unambiguous - all the logic is on the backend.
usually the logic is not particularly heavy, and one server easily holds thousands of clients.

Answer 2

Create an additional field for users. And send data to engine/addcomments.php through this created input.
I won’t write the code, but I think you can figure it out there and do it by analogy with standard fields.

Edit /engine/classes/js/dle.js
Approximately line 18 in version 14.1

$.post(dle_root+"engine/ajax/controller.php?mod=addcomments",{post_id:a.post_id.value,
