嚴格標準：非靜態方法，假設$ this來自不兼容的上下文

我有這個和「Strict Standards：call_user_func_array（）期望參數1是更新到php 5.5之後的有效回調，非靜態方法」。

我知道了解決方法是有點改變「::」，以「 - >」在某處下面的PHP，但我不能確定如何對其進行格式化..

function widget($args, $instance) { 
      extract($args); 
      $title = apply_filters('widget_title', $instance['title']); 
      echo $before_widget; 
      if ($title) 
      echo $before_title . $title . $after_title; 
      wp_custom_sidebar_plugin::query_custom_sidebar(); 
      echo $after_widget; 
     }

這是倒數第二行我需要解決...只是不知道如何寫這個PHP。

嗯，試圖改變

function widget($args, $instance) {

到

public static function widget($args, $instance) {

沒有那個錯誤編輯出來。繼承人完整的代碼 – Ramabyte

你在靜態情況下調用query_custom_sidebar當它不是一個靜態方法。嘗試使query_custom_sidebar成爲靜態函數，或者創建wp_custom_sidebar_plugin類的實例，並通過該實例調用方法query_custom_sidebar。
