Take the following steps to build a recently registered user list and display it on the site using a shortcode:

1. Open the wpcookbookchapter5.php file of the WPCookbook Chapter 5 plugin in the code editor.
2. Add the following code block to define a shortcode and callback function for the recently registered user list:

add_shortcode('wpccp_recent_user_list', 'wpccp_chapter5_recent_user_list');
function wpccp_chapter5_recent_user_list($atts,$content){
  // Step 3 code should be placed in next line
}

3. Add the following code block after the comment "// Step 3 code should be placed in next line", to query the database and generate the user list:

$user_query = new WP_User_Query( array(
 'orderby' => 'registered',
 'order' => 'ASC',
 'number' => 5
 ) );

$user_list = $user_query->get_results();
$user_list_html = '<ul>';
if(count($user_list) > 0){ 
 foreach ($user_list as $key => $user) {
 $user_list_html .= '<li>'. $user->user_login .'</li>';
 }
}else{
 $user_list_html .= '<li>'.__('No Users Found','wpccp') .'</li>';
}
$user_list_html .= '</ul>';
return $user_list_html;

Now, the shortcode is ready to display the recently registered users. Take the following steps to add the shortcode to a page and display the list on the frontend:

1. Log in to the Dashboard as an administrator.
2. Click the Pages menu from the left-hand section.
3. Click the Add New button to create a page.
4. Add a title to the page and the following shortcode as content:

[wpccp_recent_user_list]

5. Click the Publish button to create and publish the page.
6. Now, click the View Page link to view the page on the frontend with a recently registered user list, as shown in the following screenshot:

We have just displayed the username in this case. You can use other user details, such as the registered date and full name, in such a list.
