我想提醒我的插件用户，插件已启用，但仅在product 页面（仪表板），我发现$pagenow 全局变量：

global $pagenow;
$pagenow != \'post.php\'; // This will be shown on "normal posts" too

add_action(\'admin_notices\', function () {
    if (!is_admin()) {
        return;
    }

    $title = __e(\'Your plugin is enabled\');
    $div = \'<div class="notice notice-info is-dismissible"><p>%s</p></div>\';

    $pluginPath = \'path-to/my-plugin.php\';
    if (is_plugin_active($pluginPath)) {
        echo sprintf($div, $title);
    }
});
