Attention! – Geeks’ stuff ahead! 😉
<h4>API</h4>
Parameters can either be passed <a href="https://codex.wordpress.org/Function_Reference/wp_parse_args" rel="nofollow ugc">as an array or a URL query type string (e.g. “display=0&format=0”)</a>. Please note that WordPress parses all arguments as strings, thus booleans have to be 0 or 1 if used in query type strings whereas for arrays <a href="https://secure.php.net/manual/en/language.types.boolean.php" rel="nofollow ugc">real booleans</a> should be used.
<code>$featuring_countcomments->count_by_user($params=array())</code>
Counts the number of comments made by a user who is currently logged in or has a particular attribute.
$params:
<ul>
<li>
<code>user_attribute</code>: one of the user’s attributes (matching <code>query_type</code>), for example, the user_id or a WP_User object; if no user_attribute is given, will fallback to currently logged in user
</li>
<li>
<code>query_type</code>: corresponding SQL-field of user’s attribute or WP_User object; default is <code>user_id</code>
<ul>
<li>user_id</li>
<li>display_name</li>
<li>user_nicename</li>
<li>user_email</li>
<li>user_login</li>
<li>WP_User object</li>
</ul>
</li>
<li>
<code>format</code>: if set to true (default), the output will be formatted using the attributes <code>zero</code>, <code>one</code>, <code>more</code> and <code>thousands_separator</code>; false = process plain count value
</li>
<li>
<code>zero</code>, <code>one</code>, <code>more</code>: for formatted output – %c gets replaced with the number of comments
<ul>
<li>‘zero’ => ‘0 comments’</li>
<li>‘one’ => ‘1 comment’</li>
<li>‘more’ => ‘%c comments’</li>
</ul>
</li>
<li>
<code>thousands_separator</code>: divides counts by thousand delimiters; default <code>,</code> => e.g. 1,386
</li>
<li>
<code>display</code>: if you want to return the count (e.g. for storing it in a variable) instead of echoing it with this function-call, set <code>display</code> to <code>false</code>; default setting is <code>true</code>
</li>
</ul>
The following example outputs the comment count of the user with the registered e-mail address ‘j.doe@example.com’.
<pre><code><?php

global $featuring_countcomments;

$params=array(
 'query_type' => 'user_email',
 'user_attribute' => 'j.doe@example.com'
);

$featuring_countcomments->count_by_user($params);

?>
</code></pre>
<code>$featuring_countcomments->count_by_comment($params=array())</code>
Counts the number of comments made by a user who wrote a certain comment or the current comment in the comment-loop.
$params:
<ul>
<li>
<code>comment</code>: a comment object or comment id; if empty retrieves current comment
</li>
<li>
<code>format</code>: if set to true (default), the output will be formatted using the attributes <code>zero</code>, <code>one</code>, <code>more</code> and <code>thousands_separator</code>; false = process plain count value
</li>
<li>
<code>zero</code>, <code>one</code>, <code>more</code>: for formatted output – %c gets replaced with the number of comments
<ul>
<li>‘zero’ => ‘0 comments’</li>
<li>‘one’ => ‘1 comment’</li>
<li>‘more’ => ‘%c comments’</li>
</ul>
</li>
<li>
<code>thousands_separator</code>: divides counts by thousand delimiters default <code>,</code> => e.g. 1,386
</li>
<li>
<code>display</code>: if you want to return the count (e.g. for storing it in a variable) instead of echoing it with this function-call, set <code>display</code> to <code>false</code>; default setting is <code>true</code>
</li>
<li>
<code>in_loop</code>: if set to true (default), the query count for all user who wrote a comment which belongs to the post of the handed over <code>comment</code> will be cached; otherwise the comment count will be retrieved only for the user who posted the <code>comment</code>
</li>
</ul>
The following example outputs the number of comments of the author with the current comment in the comment loop:
<pre><code><?php

global $featuring_countcomments;

$featuring_countcomments->count_by_comment();

?>
</code></pre>

Invokes <code>$featuring_countcomments->count_by_comment($params)</code>.
<h4>Filters</h4>

General Example:
<pre><code>function my_featuring_countcomments_defaults($params=array()) {
 $params['query_type'] = 'user_nicename';
 return $params;
}

add_filter('featuring_countcomments_defaults', 'my_featuring_countcomments_defaults');
</code></pre>
Available Filters:
<pre><code>featuring_countcomments_defaults
</code></pre>
In case you want to set the default parameters globally rather than handing them over on every function call, you can add the <a href="https://codex.wordpress.org/Function_Reference/add_filter" rel="nofollow ugc">filter</a> <code>featuring_countcomments_defaults</code> in for example featuring-countcomments.php or your <a href="https://codex.wordpress.org/Writing_a_Plugin" rel="nofollow ugc">own customization plugin</a> (recommended).
Please note that parameters which you hand over to a function call (<code>$featuring_countcomments->count_by_user</code> or <code>$featuring_countcomments->count_by_comment</code>) will always override the defaults parameters, even if they have been set by a filter or in the admin menu.

HelgaTheViking

Other plugins output paginated lists of users, but I needed to be able to customize and style this list to fit my theme. So I created this plugin to use templates that can be overridden and customized by theme developers.
To customize any of the templates, copy the file from the plugin’s “templates” folder to your themes “simple-user-listing” folder.
<h4>Usage</h4>
Place this shortcode anywhere you’d like to display a full list of all your blog’s users.
<pre><code>[userlist]
</code></pre>
By default the plugin will print out the users based on the “Posts per Page” setting under Settings->Reading, but this and many other settings can be changed via the shortcode’s parameters.
<h4>Support</h4>
If after reading the <a href="https://wordpress.org/plugins/simple-user-listing/faq" rel="ugc">FAQ</a> you still need help, support is handled in the <a href="https://wordpress.org/support/plugin/simple-user-listing" rel="ugc">WordPress forums</a>. Please note that support is limited and does not cover any custom implementation of the plugin.
Please report any bugs, errors, warnings, code problems to <a href="https://github.com/helgatheviking/simple-user-listing/issues" rel="nofollow ugc">Github</a>
