WordPress 随机显示已注册的用户

之前我们分享过 WordPress 显示最近注册的用户，今天再来实现 随机显示已注册的用户。方法其实都几乎一样，仅仅是查询数据库的代码有点差异罢了。

将下面的代码添加到当前主题的 functions.php：

/**
 * WordPress 随机显示已注册的用户
 * https://www.wpdaxue.com/display-random-registered-users.html
 */
function wpb_random_users() { 
	global $wpdb;
	$randomusers = '<ul class="random-users">';
	// 查询数据库，随机获取 5 位已注册用户
	$usernames = $wpdb->get_results("SELECT user_nicename, user_url, user_email FROM $wpdb->users ORDER BY RAND() LIMIT 5");
	// 将用户已列表的形式显示
	foreach ($usernames as $username) {
		if (!$username->user_url) :
			$randomusers .= '<li>' .get_avatar($username->user_email, 45) .$username->user_nicename."</li>";
		else :
			$randomusers .= '<li>' .get_avatar($username->user_email, 45).'<a href="'.$username->user_url.'">'.$username->user_nicename."</a></li>";
		endif;
	}
	$randomusers .= '</ul>';
	return $randomusers;  
}
// 添加简码
add_shortcode('randomusers','wpb_random_users');

/**
* WordPress 随机显示已注册的用户
* https://www.wpdaxue.com/display-random-registered-users.html
*/
function wpb_random_users() {
global $wpdb;
$randomusers = ‘<ul class="random-users">’;
// 查询数据库，随机获取 5 位已注册用户
$usernames = $wpdb->get_results("SELECT user_nicename, user_url, user_email FROM $wpdb->users ORDER BY RAND() LIMIT 5");
// 将用户已列表的形式显示
foreach ($usernames as $username) {
if (!$username->user_url) :
$randomusers .= ‘<li>’ .get_avatar($username->user_email, 45) .$username->user_nicename."</li>";
else :
$randomusers .= ‘<li>’ .get_avatar($username->user_email, 45).'<a href="’.$username->user_url.’">’.$username->user_nicename."</a></li>";
endif;
}
$randomusers .= ‘</ul>’;
return $randomusers;
}
// 添加简码
add_shortcode(‘randomusers’,’wpb_random_users’);

然后你就可以在模板中使用下面 的函数调用

1

<?php wpb_random_users(); ?>

<?php wpb_random_users(); ?>

或者在文章、页面或小工具中使用下面的简码调用

[randomusers]
