在另一个类中使用Add_Filter

我正在构建一个生成自定义css的插件，我有两个类：

主类，其核心函数编译器类如下（我简化了所有内容，因为有很多选项）：

class compiler 
{
   public function __construct(){
      $this->generateCss();
      $this->enqueueCss();
      //other functions
   }
   public function generateCss(){
      //this is the filter
      $css = apply_filters(\'dynamic_css\', \'.your_code{}\');
      $content = $css;
      //the rest of the function which generates and upload the file
   }
   //other functions to enqueue the generated file
}

$compiler = new compiler();

class my_class
{
   public function __construct() {
      //blablabla
      $this->pluginSetup();
   }
   public function pluginSetup(){
      //other functions to save css in option "custom css"
      add_action(\'admin_init\', array($this, \'set_css\'));
   }
   public function set_css(){
      add_filter( \'dynamic_css\', array( $this, \'load_custom_css\' ));
   }
   public function load_custom_css(){
      //css has been inserted in option "custom css" through omitted functions
      $css = get_option("custom_css");
      return $css;
   }
}
$my_class = new my_class();

文件已正确生成并排队，但筛选器dynamic_css 不起作用，我只得到默认值.your_code{}.

中的代码option("custom_css") 存在并在上有效var_dump().

我想把这两个类分开，但我找不到解决方案，我试图改变初始化顺序，但没有成功。

class compiler { public function generateCss(){ $css = apply_filters( \'dynamic_css\', \'.your_code{}\' ); $this->content = $css; } } $compiler = new compiler(); add_action( \'admin_init\', [ $compiler, \'generateCss\' ], 11 ); class my_class { public function set_css(){ add_filter( \'dynamic_css\', [ $this, \'load_custom_css\' ); } public function load_custom_css(){ return get_option( \'custom_css\' ); } } $my_class = new my_class(); add_action( \'admin_init\', [ $my_class, \'set_css\' ], 10 );

Ajax with plugins returns 0

我正在尝试在中创建按钮edit-comments 表，我想使用Ajax和一个插件来完成这项任务。这是插件/无电子邮件/无电子邮件下插件的代码。php：<?php /* Plugin Name: Approve Comment but don\'t send email Plugin URI: \"\" Description: Approve commnet or Trash Commnet but don\'t send the email.
