  尝试使用 apply_filters 而不是 add_action

  我自己最终解决了这个问题 . 我尝试了Paul de Koning的回答 . 更改为apply_filters导致价格变为$ 0 . 我认为这是因为他们需要进入的顺序 .

  这是我的解决方案 . 根本原因是我使用change price_html函数来提供购物车的更改价格 . 在该函数内部有add_action调用等 . 不知何故，必定存在一个排序问题 . 这是一个多步骤过程，以确保所有区域都正确完成 .

  如果您想更改woocommerce价格而不使用会话来存储更改显示价格和隐藏价格的购物车更改价格，请执行以下操作：

  functions.php

  add_action('woocommerce_get_price_html','special_price');
  
      function special_price($price) {
  
         //put any if statements for hiding the cart button and discounting pricing below and return true or false
         $displayprice = true;
         $alterprice   = true;
  
         if($displayprice === true) {
  
           add_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart', 10, 2);
           add_action( 'init', 'woocommerce_add_to_cart_action', 10);
           add_action( 'init', 'woocommerce_checkout_action', 10 );
  
         } else {
  
          remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart', 10, 2);
          remove_action( 'woocommerce_before_add_to_cart_form', 'woocommerce_template_single_product_add_to_cart', 10, 2);        //   
          remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 );
          remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );
  
          //return blank or something like 'Signup to view price'
          return '';
  
         }
  
         //if you are displaying the price (altered)
         if($displayprice === true && $alterprice === true){
  
           $price = price_manipulator($theid);
           return $price;
  
           //display add to cart and price
  
         } 
  
         //if you are displaying the price (unaltered)
         return $price       
  
       }
  
  
      function price_manipulator($theid = '') {
  
        if(empty($theid)){
          $theid = get_the_ID();
        }
  
        $product = wc_get_product($theid);
  
        //30% off example
        $newprice = floatval($product->price * (1-0.3));
  
        return $newprice;
      }
  
     /*version of pricing if you are adding something to cart*/
      function special_price_cart($theid){
  
                $price = price_manipulator($theid);             
  
                return $price;
  
      }
  
  
      add_action( 'woocommerce_before_calculate_totals', 'woo_add_discount');
      add_action( 'woocommerce_before_mini_cart', 'woo_add_discount'); //this is if you are using the mini-cart woocommerce widget
  
      function woo_add_discount() {
  
         global $woocommerce;    
  
         //create if statements same as if you were displaying the price 
         $displayprice = true;
  
  
         if($displayprice === true){  
  
           foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) { 
  
             $price = special_price_cart($cart_item['data']->id);
             $price = str_replace('$','',$price);
             $price = str_replace(',','',$price);               
  
  
             if($price > 0){
  
               $cart_item['data']->price = floatval($price);
  
             }    
  
         }
  
       } 
  
    }
