未捕获的 ArgumentCountError：函数 order_completed() 的参数太少。在 woocommerce_order_status_completed 挂钩上

Question

我收到以下错误：

[2021 年 11 月 30 日 16:08:47 UTC] PHP 致命错误：未捕获的 ArgumentCountError：函数 order_completed() 的参数太少，1 个传入 /home/brantsho/public_html/wp-includes/class-wp-hook.php在第 305 行和 /home/brantsho/public_html/wp-content/themes/glowing/functions.php:28 中预期的第 4 行堆栈跟踪：#0 /home/brantsho/public_html/wp-includes/class-wp-hook。 php(305): order_completed() #1 /home/brantsho/public_html/wp-includes/class-wp-hook.php(327): WP_Hook->apply_filters() #2 /home/brantsho/public_html/wp-includes /plugin.php(470): WP_Hook->do_action() #3 /home/brantsho/public_html/wp-content/plugins/woocommerce/includes/class-wc-order.php(364): do_action() #4 / home/brantsho/public_html/wp-content/plugins/woocommerce/includes/class-wc-order.php(222): WC_Order->status_transition() #5 /home/brantsho/public_html/wp-content/plugins/woocommerce/包括/class-wc-order.php(334): WC_Order->save() #6 /home/brantsho/public_html/wp-content/plugins/woocommerce/includes/class-wc-ajax.php(530): WC_Order ->update_status() #7 /home/brantsho/public_html/wp-incl 在 /home/brantsho/public_html/wp-content/themes/glowing/functions.php 第 28 行

但我的functions.php 看起来不错：

<?php
if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly
}

define('GLOWING_VERSION', '1.0.0');
define('GLOWING_FILE_HANDLER', basename(get_template_directory()) . '-');

if (function_exists('WC')) {
    include_once get_parent_theme_file_path('inc/woocommerce.php');
}


add_action( 'woocommerce_order_status_completed', 'order_completed',10,1);
function order_completed($order_id, $old_status, $new_status, $order) {
  
  if( $new_status == "completed" ) {
    
    $order = wc_get_order( $order_id );
    $total = $order->get_total();
    $coin_avl = $total*25/100;
    
    wp_update_user( array(
        'ID' => get_current_user_id(),
        'avl_coin' => $coin_avl
   ) ); 
    
  }
}

请你帮我解决一下..

您已将4参数传递给回调函数，但在挂钩中您仅指定了1.

代替

add_action( 'woocommerce_order_status_completed', 'order_completed',10,1);

和

add_action( 'woocommerce_order_status_completed', 'order_completed', 10, 4);
