这个Twenty Eleven Theme 有一些不错的代码注释来解释发生了什么。

快速和肮脏概述：

所有注释功能都可以使用comments.php. 您可以使用适当的名称将其包含到模板中comments_template 它做了很多事情（设置当前评论员等），而不仅仅是包含“评论”。php

你的comments.php 模板可能如下所示。

<?php
// Is the post password protected?  Maybe you want to deal with that.
if(post_password_required())
{
    // show a message to the users about the password requirement.

    // `return` out of the file, don\'t show anything else
    return;
}

// display the comments if they exist
if(have_comments())
{
    // maybe a header or something here

    // wp_list_comments (http://codex.wordpress.org/Function_Reference/wp_list_comments) 
    // actually displays the comments -- it will just work if
    // you use it without any arguments
    wp_list_comments();

    // You can also specify a custom callback to display things:
    // wp_list_comments(array(\'callback\' => \'your_comment_callback\'));
}

// are comments open? display the comment form!
if(comments_open())
{
    // `comment_form` does all the work. You can customize it
    // with arguments and filters. Like wp_list_comments this
    // will just work.
    // http://codex.wordpress.org/Function_Reference/comment_form
    comment_form();
}
else
{
    // display a message about comments being close for visitors
    // this optional -- personally, I prefer to show no message.
}
