I introduced you to "The whole process of WordPress theme production (9): Making single.php". This article continues to introduce to you how to make comments.php. Let's take a look at it together~

The whole process of WordPress theme creation (10): making comments.php

Today we will make the comment module of the comment theme. Create a new comments.php under the theme directory Aurelius, cut the following code in single.php, and paste it into comments.php:

<!– Comment’s List –>
<h3>Comments</h3>
<div class="hr dotted clearfix"> </div>
<ol class="commentlist">
<li class="comment">
<div class="gravatar"> <img alt="" src=’images/gravatar.png’ height=’48′ width=’48′ /> <a class="comment-reply-link" href=">Reply</a> </div>
<div class="comment_content">
<div class="clearfix"> <cite class="author_name"><a href="">Joe Bloggs</a></cite>
<div class="comment-meta commentmetadata">January 6, 2010 at 6:26 am</div>
</div>
<div class="comment_text">
<p>Donec leo. Aliquam risus elit, luctus vel, interdum vitae, malesuada eget, elit. Nulla vitae ipsum. Donec ligula ante, bibendum sit amet, elementum quis, viverra eu, ante. Fusce tincidunt. Mauris pellentesque, arcu eget feugiat accumsan, ipsum mi molestie orci, ut pulvinar sapien lorem nec dui.</p>
</div>
</div>
</li>
</ol>
<div class="hr clearfix"> </div>
<!– Comment Form –>
<form id="comment_form" action="" method="post">
<h3>Add a comment</h3>
<div class="hr dotted clearfix"> </div>
<ul>
<li class="clearfix">
<label for="name">Your Name</label>
<input id="name" name="name" type="text" />
</li>
<li class="clearfix">
<label for="email">Your Email</label>
<input id="email" name="email" type="text" />
</li>
<li class="clearfix">
<label for="email">Your Website</label>
<input id="website" name="website" type="text" />
</li>
<li class="clearfix">
<label for="message">Comment</label>
<textarea id="message" name="message" rows="3" cols="40"></textarea>
</li>
<li class="clearfix">
<!– Add Comment Button –>
<a type="submit" class="button medium black right">Add comment</a> </li>
</ul>
</form>

Add the code in the original location of single.php:

<?php comments_template(); ?>

The above statement The function is to import all the contents in comments.php into single.php, which has the same effect as writing the code in comments.php directly in single.php.

For the sake of security, to prevent malicious users from opening the comment file directly, please add the following code in the comments.php header:

<?php
if (isset($_SERVER[&#39;SCRIPT_FILENAME&#39;]) && &#39;comments.php&#39; == basename($_SERVER[&#39;SCRIPT_FILENAME&#39;]))
die (&#39;Please do not load this page directly. Thanks!&#39;);
?>

Copy after login

Because the comment code output by WordPress's output comment function wp_list_comments() Different from the comment code of our theme, we have to customize our comment list and delete the following code in comments.php (the following code is used to list all comments on the article):

<li class="comment">
<div class="gravatar"> <img alt="" src=’images/gravatar.png’ height=’48′ width=’48′ /> <a class="comment-reply-link" href=">Reply</a> </div>
<div class="comment_content">
<div class="clearfix"> <cite class="author_name"><a href="">Joe Bloggs</a></cite>
<div class="comment-meta commentmetadata">January 6, 2010 at 6:26 am</div>
</div>
<div class="comment_text">
<p>Donec leo. Aliquam risus elit, luctus vel, interdum vitae, malesuada eget, elit. Nulla vitae ipsum. Donec ligula ante, bibendum sit amet, elementum quis, viverra eu, ante. Fusce tincidunt. Mauris pellentesque, arcu eget feugiat accumsan, ipsum mi molestie orci, ut pulvinar sapien lorem nec dui.</p>
</div>
</div>
</li>

Change to :

<?php 
    if (!empty($post->post_password) && $_COOKIE['wp-postpass_' . COOKIEHASH] != $post->post_password) { 
        // if there's a password
        // and it doesn't match the cookie
    ?>
    <li class="decmt-box">
        <p><a href="#addcomment">请输入密码再查看评论内容.</a></p>
    </li>
    <?php 
        } else if ( !comments_open() ) {
    ?>
    <li class="decmt-box">
        <p><a href="#addcomment">评论功能已经关闭!</a></p>
    </li>
    <?php 
        } else if ( !have_comments() ) { 
    ?>
    <li class="decmt-box">
        <p><a href="#addcomment">还没有任何评论，你来说两句吧</a></p>
    </li>
    <?php 
        } else {
            wp_list_comments(&#39;type=comment&callback=aurelius_comment&#39;);
        }
    ?>

Copy after login

You can roughly see the meaning of the above code, which is a lot of if... then..., if the above conditions are not met, all comments will be listed. Now change the ?> in functions.php in the theme folder Aurelius to the following code. If the functions.php you downloaded from this blog before already has the following code, there is no need to add it:

function aurelius_comment($comment, $args, $depth) 
{
   $GLOBALS['comment'] = $comment; ?>
   <li class="comment" id="li-comment-<?php comment_ID(); ?>">
<div class="gravatar"> <?php if (function_exists(&#39;get_avatar&#39;) && get_option(&#39;show_avatars&#39;)) { echo get_avatar($comment, 48); } ?>
 <?php comment_reply_link(array_merge( $args, array(&#39;reply_text&#39; => '回复','depth' => $depth, 'max_depth' => $args['max_depth']))) ?> </div>
<div class="comment_content" id="comment-<?php comment_ID(); ?>">
<div class="clearfix">
<?php printf(__('<cite class="author_name">%s</cite>'), get_comment_author_link()); ?>
<div class="comment-meta commentmetadata">发表于：<?php echo get_comment_time(&#39;Y-m-d H:i&#39;); ?></div>
   <?php edit_comment_link(&#39;修改&#39;); ?>
</div>
<div class="comment_text">
<?php if ($comment->comment_approved == '0') : ?>
<em>你的评论正在审核，稍后会显示出来！</em><br />
      <?php endif; ?>
      <?php comment_text(); ?>
</div>
</div>
<?php } ?>

WordPress functions used in the above code and corresponding descriptions:
