我们有一个用于监控客户网站性能的网站，我们正在使用商业智能 wordpress 插件向客户展示有关性能的信息。当一个新客户第一次登录并选择他的仪表板时，我们收到以下错误，当我们在数据库中更新时，错误消失但仪表板第一次应该显示自定义消息。 我正在使用以下 sql 查询

select lastsamplestatus,lasterrorat,avguptimeday,status from
selenium_script_data as ssd inner join selenium_scripts as ss
on ss.script_id=ssd.selenium_id inner join wp_users as wu on 
wu.ID=ss.customer_id where wu.ID={{{user_ID}

我们想在管理员更新数据库之前为用户显示一条普通的自定义消息，我不知道在哪里自定义 functions.php，我从 wordpress 的商业智能插件中获得了这个文件。 我在下面粘贴了部分代码，我们将不胜感激。

最佳答案

好的 friend 。放轻松。

这里有几点需要注意:

1 - 显示错误是因为您的 error_reporting 设置为 E_ALL。如果您像下面这样设置，将不会显示错误。

error_reporting(E_ALL ^ E_NOTICE ^ E_WARNING);

但是，它不会解决代码上的错误。只会隐藏它。

2 - 当您看到“为 foreach() 提供的参数无效”时，您的代码正在尝试迭代一个空变量。您需要转到该文件和行，然后做一些简单的事情:

if ($yourVariable && count($yourVariable)>0)
   foreache($yourVariable as $yourValue){
   }

它将防止使用无效变量调用 foreach。

3 - 当它在该行显示“尝试获取非对象的属性”时，您有一个不是对象的变量。它可以是一个字符串，或一个整数..或其他任何东西..它只是不是一个对象。

查看所有错误，您可以看到 data 变量为空，然后所有错误都发生在这之后，因为该代码始终与 $data 一起运行。尝试检查您的代码以确保 $data 在启动之前具有值。
