我们正在建立一个监控客户网站性能的网站，我们正在使用商业智能wordpress插件来显示客户端的性能。当新客户端首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，错误消失但第一次仪表板应显示自定义消息。 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}

我们要为用户显示正常的自定义消息，直到管理员更新数据库，我不知道在哪里定制functions.php，我从wordpress的商业智能插件获取此文件。 我已粘贴下面的部分代码，我们将不胜感激。

答案 0 :(得分：1)
你必须注意一些事情：
1 - 显示错误是因为您的error_reporting设置为E_ALL。如果您将其设置如下，则不会显示错误。
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空变量。你需要去那个文件和行，然后做一些事情：
if ($yourVariable && count($yourVariable)>0)
foreache($yourVariable as $yourValue){
}
它将阻止使用无效变量调用foreach。
3 - 当它说“试图获取非对象的属性”时，在该行上，你有一个不是对象的变量。它可以是字符串，也可以是整数......或其他任何东西......它只是不是一个对象。
查看所有错误，您可以看到数据变量为空，然后在此之后发生所有错误，因为该代码始终以$ data运行。尝试检查您的代码，以确保$ data在启动开关之前具有该值。
