在Woocommerce中,我有一个简单的函数可以返回购物车项目,当我在function.php中调用此函数时,我会出错。

<?php 
class Theme { 
 public static $version;
 function __construct() { 
  $theme = wp_get_theme();
  self::$version = $theme['Version'];   
  $this->cart_items(); 
  } 
 function cart_items(){ 
   var_dump(get_users()); 
 } 
new Theme();

我有这个错误:

  

致命错误:未捕获错误:调用成员函数get_cart_contents()为空

  $this->cart_items(); 
  } 
 function cart_items(){ 
   var_dump(get_users()); 
 } 
}
new Theme();
