Wordpress -商业智能Lite插件

Question

我们有一个网站，用于监测客户网站的性能，我们使用商业智能wordpress插件显示客户端的性能。当一个新客户机首次登录并选择他的仪表板时，我们将得到以下错误，当我们在数据库中更新时，错误会消失，但是仪表板应该第一次显示自定义消息。我使用以下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}

注意:未定义变量:第405行/home/sgulechha/alert.com/wp-content/plugins/wp-business-intelligence-lite/functions/functions.php中的label_x

注意:未定义变量:第417行/home/sgulechha/alert.com/wp-content/plugins/wp-business-intelligence-lite/functions/functions.php中的数据

警告:在第417行为/home/sgulechha/alert.com/wp-content/plugins/wp-business-intelligence-lite/functions/functions.php中的foreach()提供无效的参数

注意:尝试在第60行的/home/sgulechha/alert.com/wp-content/plugins/wp-business-intelligence-lite/resources/nvd3/wrappers/nvd3_lineChart.php中获取非对象的属性。

注意:第154行/home/sgulechha/alert.com/wp-content/plugins/wp-business-intelligence-lite/resources/nvd3/wrappers/nvd3_lineChart.php中的未定义变量: ds

注意:试图在第154行的/home/sgulechha/alert.com/wp-content/plugins/wp-business-intelligence-lite/resources/nvd3/wrappers/nvd3_lineChart.php中获取非对象的属性。

注意:未定义变量:第158行/home/sgulechha/alert.com/wp-content/plugins/wp-business-intelligence-lite/functions/functions.php中的表

注意:试图在第158行的/home/sgulechha/alert.com/wp-content/plugins/wp-business-intelligence-lite/functions/functions.php中获取非对象的属性。

我们想为用户显示一个正常的自定义消息，直到管理更新数据库，我不知道在哪里定制functions.php，我从商业智能插件的wordpress得到这个文件。我已经粘贴了下面的代码的一部分，任何帮助都将不胜感激。

//Assign values and labels
    switch($wpbi_chart->type){

Answer 1

好的朋友。放轻松点。

在这里，你必须注意一些事情：

显示错误是因为您的error_reporting被设置为E_ALL。如果您将其设置为下面所示，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。会把它藏起来。

2-当您看到“为foreach()提供的无效参数”时，您的代码试图迭代一个空变量。你需要找到那个文件和行，然后做些事情：

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

它将防止使用无效变量调用foreach。

3-当它说“试图获取非对象的属性”时，在该行中，您有一个不是对象的变量。它可以是字符串，也可以是整数。或者别的什么..。只是它不是一个物体。

查看所有错误，您可以看到数据变量是空的，然后所有错误都会发生，因为代码总是与$data一起运行。尝试检查您的代码，以确保$data在开关启动前具有该值。
