我正在用短代码做一个插件。我有一些类扩展了一个称为Shortcode的抽象类。

abstract class Shortcode {

    public $tag;
    public $attrs;
    public $function;

    public function __construct($tag) {
        $this->attrs = array();
        $this->tag = $tag;
        $this->function = static::className().\'::getCallBack\';

        add_shortcode( $this->tag, $this->function );

        $this->init();
    }

    protected function init(){
       if( !is_admin() ){
           //Front-end
           error_log(\'test 1\');
           add_action(\'wp\',  array( $this , \'check_page\' ) );
       }
    }

    abstract public function check_page();

    abstract public static function className();

    abstract public static function getCallBack( $attrs );
}

My Shortcode class

class MyShortcode extends Shortcode {

    public function check_page(){
         error_log( "test 2" );
         global $post;
         $pattern = \'/(\\[\'.$this->tag.\'\\])/\';
         if( !empty( $post->post_content ) && preg_match(  $pattern, $post->post_content ) ){
            add_action(\'wp_enqueue_scripts\', array( $this , \'set_styles\'));
        }
    }

    public static function getCallBack( $attrs = null ){
       ...
    }

    //CSS stylesheets
    public function set_styles() {
        //wp_enqueue_style( \'wgsstyle\', PLUGIN_DIR_URL . \'front-end/views/css/wgs-front-end.css\' );
        //wp_enqueue_style( \'wgscardsstyle\', PLUGIN_DIR_URL . \'front-end/views/css/wgs-cards.css\' );
    }

    public static function className(){
        return __CLASS__;
    }

}

发生的事情很奇怪。。。正在调试中。日志，它写的是“测试1”，但不是“测试2”，css样式表仍在加载。

是否有用于短代码的缓存？如何重新初始化此代码？
