我想修改已登录用户和未登录用户的评论表单。

我通过更改注释修改了未登录用户的表单。php，但我不太确定如何为登录用户修改我的表单。我知道我必须使用comments\\u template（），但每当我尝试在页面中使用它时。php，我遇到这样的错误

Notice: Undefined variable: args in {PATH}/twwr-theme/comments-template.php on line 13 

<?php
if (!empty($_SERVER[\'SCRIPT_FILENAME\']) && \'comments.php\' == basename($_SERVER[\'SCRIPT_FILENAME\']))
    die (\'Please do not load this page directly. Thanks!\');

if ( post_password_required() ) {
    echo "This post is password protected. Enter the password to view comments.";
    return;
}
?>

<h3><?php comments_number(\'No Comments\', \'One Comment\', \'Comments\' );?></h3>

<div class="navigation">
    <div class="next-posts"><?php previous_comments_link() ?></div>
    <div class="prev-posts"><?php next_comments_link() ?></div>

    <?php //comment layout is in functions.php ?>

<?php if ( comments_open() ) : ?>
    <!-- If comments are open, but there are no comments. -->

 <?php else : // comments are closed ?>
    <p>Comments are closed.</p>

<?php endif; ?>
