要使用` get_users `函数获取所有用户列表，可以按照以下步骤进行：
1. 使用` get_users `函数调用获取用户列表：
$users = get_users();
2. 您可以按需使用参数来过滤结果。例如，您可以通过角色、用户ID、用户登录名等过滤用户列表。以下是一个根据用户角色为过滤条件的示例：
$users = get_users( array(
'role' => 'subscriber' // 将角色名称替换为您要过滤的角色
) );
在上述示例中，将` role `参数设置为所需的角色名称来过滤用户列表。
3. 您可以使用循环遍历获取的用户列表，并访问每个用户的属性。例如，以下示例将显示每个用户的用户名和电子邮件地址：
foreach( $users as $user ) {
echo '用户名：' . $user->user_login . ', 电子邮件：' . $user->user_email . ;
}
在上述示例中，通过` $user->user_login `和` $user->user_email `访问每个用户的用户名和电子邮件地址。
请注意，` get_users `函数默认返回所有用户，并可以根据需要使用更多参数进行过滤。您可以参阅WordPress官方文档中的` get_users `函数文档，了解更多可用参数和用法示例。
总结起来，使用` get_users `函数获取所有用户列表的步骤是：
get_users `函数获取用户列表。在WordPress中，可以使用WP_PLUGIN_DIR和WP_PLUGIN_URL常量来定义插件的目录路径和URL。
1. `WP_PLUGIN_DIR`：这是一个常量，用于定义插件的目录路径（文件系统路径）。您可以使用以下代码在插件文件中访问该常量：
$plugin_dir = WP_PLUGIN_DIR . '/your-plugin-folder/';
在上述代码中，将"your-plugin-folder"替换为您插件的实际文件夹名称。使用该常量，您可以获取插件文件的完整路径。
2. `WP_PLUGIN_URL`：这是一个常量，用于定义插件的URL（用于在网页上访问插件文件）。以下是一个使用该常量的示例：
$plugin_url = WP_PLUGIN_URL . '/your-plugin-folder/';
同样，请将"your-plugin-folder"替换为您插件的实际文件夹名称。使用该常量，您可以获取插件在网页上的完整URL。
请注意，`WP_PLUGIN_DIR`和`WP_PLUGIN_URL`常量在WordPress版本2.6之后引入。从WordPress 5.5版本开始，这两个常量被标记为过时（deprecated），因为WordPress更倾向于使用新的插件文件结构。如果您正在开发新插件，建议使用新的插件文件结构和相关函数。
在新的插件文件结构中，可以使用以下函数来获取插件的目录路径和URL：
- `plugin_dir_path()`：获取插件目录路径。
- `plugin_dir_url()`：获取插件URL。
这些函数会自动将插件的版本、多站点和SSL等考虑因素纳入计算。
总结起来，使用`WP_PLUGIN_DIR`和`WP_PLUGIN_URL`常量定义插件的目录和URL的方法是：
$plugin_dir = WP_PLUGIN_DIR . '/your-plugin-folder/'; $plugin_url = WP_PLUGIN_URL . '/your-plugin-folder/';
但请注意，这两个常量已被标记为过时，建议使用新的插件文件结构和相关函数来获取插件的路径和URL。
使用PHP在WordPress中添加自定义功能可以通过以下方式实现：
下面是一个实操示例。
要在WordPress中添加自定义功能，可以按照以下步骤使用PHP编写并添加自定义功能：
// 添加自定义功能示例
// 1. 创建自定义短代码
function custom_shortcode() {
return '这是我的自定义短代码内容';
}
add_shortcode('custom', 'custom_shortcode');
// 2. 自定义小工具
function custom_widget() {
echo '这是我的自定义小工具内容';
}
register_widget('custom_widget');
// 3. 自定义菜单
function custom_menu() {
register_nav_menu('custom-menu', '自定义菜单');
}
add_action('after_setup_theme', 'custom_menu');
// 4. 自定义页面模板
function custom_page_template() {
/* Template Name: 自定义模板 */
// 自定义模板的内容和样式
}
请注意，修改主题文件可以在主题更新时丢失，因此建议在进行任何更改之前备份functions.php文件。此外，为避免不必要的错误和冲突，建议在添加自定义功能前先了解WordPress开发文档和最佳实践，以确保正确、安全地实现所需的自定义功能。
使用 do_action 函数可以触发一个钩子函数。do_action 函数的参数与要触发的钩子函数的参数相同。
例如，触发save_post钩子函数的代码如下：
do_action( 'save_post', $post_ID, $post );
这里，$post_ID 和 $post 是传递给钩子函数的参数。
使用 wp_get_current_user 获取当前登录用户的信息：
$current_user = wp_get_current_user(); // 获取当前用户的ID $user_id = $current_user->ID; // 获取当前用户的用户名 $user_login = $current_user->user_login; // 获取当前用户的邮箱 $user_email = $current_user->user_email; // 获取当前用户的显示名称 $display_name = $current_user->display_name;
