我一直在寻找相当长的一段时间，我发现的所有内容都是3 - 4年前的教程，解释了如何进行指针巡视。我想要做的就是添加一个指针，当有人激活我的插件时弹出这个指针，以便我可以通知他们一个新的菜单选项，他们将在那里查看我的插件设置。任何帮助将不胜感激！

您正在寻找的是WordPress Activation / Deactivation Hooks。例如：
<div id="recent-blog-entries">
<header><h1>Recent Blog Entries</h1></header>
<?php $postslist = get_posts('numberposts=2&order=DESC&orderby=date');
foreach ($postslist as $post) : setup_postdata($post); ?>
<h2 class="rbe-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<p class="rbe-posted-on">Posted on: <?php the_time(get_option('date_format')) ?></p>
<div class="rbe-excerpt"><?php the_excerpt(); ?></div>
<?php endforeach; ?>
<?php wp_reset_postdata(); ?>
</div>
在register_activation_hook( __FILE__, 'pluginprefix_function_to_run' );
上，显示一条不错的消息，让用户知道您使用admin_notices添加了一个菜单：

WP中的指针需要3个组件：
1：wp-pointer css文件
2：wp-pointer JS文件
3：JavaScript代码段
至1和2
将它们简单地包括在内：
wp_enqueue_style( 'wp-pointer' );
和
wp_enqueue_script( 'wp-pointer' );
JS代码：
<script type="text/javascript">
(function($){
var options = {"content":"<h3>Personal Data and Privacy<\/h3><h4>Personal Data Export and Erasure<\/h4><p>New <strong>Tools<\/strong> have been added to help you with personal data export and erasure requests.<\/p><h4>Privacy Policy<\/h4><p>Create or select your site’s privacy policy page under <strong>Settings > Privacy<\/strong> to keep your users informed and aware.<\/p>","position":{"edge":"left","align":"bottom"},"pointerClass":"wp-pointer arrow-bottom","pointerWidth":420}, setup;
if ( ! options )
return;
options = $.extend( options, {
close: function() {
$.post( ajaxurl, {
pointer: 'wp500_isrc_pointer',
action: 'dismiss-wp-pointer'
});
}
});
setup = function() {
$('#menu-settings').first().pointer( options ).pointer('open');
};
if ( options.position && options.position.defer_loading )
$(window).bind( 'load.wp-pointers', setup );
else
$(document).ready( setup );
})( jQuery );
</script>
当然，您需要将它们全部包装在php文件中以检查用户功能并检查用户元素中的消除。
我已经在wp-admin / includes / class-wp-internal-pointers中复制了WP指针类，并从中创建了一个自定义类。
这里是完整的代码，我可以使用动作挂钩调用它：
add_action( 'admin_enqueue_scripts', array( 'isrc_Internal_Pointers', 'enqueue_scripts') );
add_action( 'user_register',array( 'isrc_Internal_Pointers', 'dismiss_pointers_for_new_users' ) );
完整的PHP文件（将其包含在您的代码中并调用2个操作）：
<?php

*
* @package WordPress
* @subpackage Administration
