This plugin allows to display or retrieve comments posted by a user. In order to avoid homonyms, a user is identified by his name and email(s).
Note: Get Author’s Comments uses the function <a href="https://codex.wordpress.org/Template_Tags/wp_list_comments" rel="nofollow ugc">wp_list_comments</a> introduced by WordPress 2.7 for the (x)HTML output.
<h3>Usage</h3>
<h4>Display all comments of a specific user in the current post</h4>
<pre><code><?php
 <ol>
 <?php ppm_author_comments('piouPiouM', 'foo@example.com'); ?>
 </ol>
?>
</code></pre>
or, if piouPiouM wrote with two different emails:
<pre><code><?php
 <ol>
 <?php ppm_author_comments('piouPiouM', array('foo@example.com', 'bar@example.org')); ?>
 </ol>
?>
</code></pre>
<h4>Display all comments posted by a user</h4>
<pre><code><?php
 <ol>
 <?php ppm_author_comments('piouPiouM', 'foo@example.com', null, 'all=1'); ?>
 </ol>
?>
</code></pre>
<h4>Display comments wrote by a user in the post of ID number 9</h4>
<pre><code><?php
 <ol>
 <?php ppm_author_comments('piouPiouM', 'foo@example.com', 9); ?>
 </ol>
?>
</code></pre>
Note: If you used the tags <code>ppm_author_comments</code> or <code>ppm_get_author_comments</code> whithin <a href="https://codex.wordpress.org/The_Loop" title="The Loop « WordPress Codex" rel="nofollow ugc">The Loop</a>, the parameter <code>$postID</code> will be replaced automatically by the numeric ID of the current post.
<h4>Lastest comments ordered by post_ID</h4>
To show the last ten piouPiouM’s comments sorted by post_ID in ascending order, the following will display their comment date and excerpt:
<pre><code><?php
 $comments = ppm_get_author_comments('piouPiouM', 'foo@example.com', null, 'number=10&order=ASC&orderby=post_id');
 foreach ($comments as $comment):
?>
<cite><?php comment_author_link() ?></cite> says:
<ol>
 <li>
 Comment posted on <?php comment_date('n-j-Y'); ?>: 
 <?php comment_excerpt(); ?>
 </li>
</ol>
<?php endforeach; ?>
</code></pre>
<h4>Comments with a custom comment display</h4>
<pre><code><?php
 <ol>
 <?php ppm_author_comments('piouPiouM', 'info@example.com', null, 'callback=mytheme_comment'); ?>
 </ol>
?>
</code></pre>
