get_block_editor_settings ( $custom_settings, $block_editor_context )

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;
