谢谢：）您的问题很简单，在这部分代码中：
} else {//registo
$data=array(
'username'=>$_POST['username'],
$data您正试图在视图文件中使用未定义的变量“$data”（显然比您发布的要长，因为它位于第141行）。这可能是一个好的开始。猜测一下，您正试图引用$data，因为这是控制器中设置的。但是在视图中，数据数组的键是作为变量可用的，例如：控制器中的$data['prodTYPE']在视图中变为$prodTYPE我更改了错误消息，行号是正确的，您所说的我已经做了，但仍然不起作用。您的视图文件在这里只显示了2行。第143行报告了错误。您没有告诉我们的form_helper中引用了哪个函数。我已经添加了您所说的行，很抱歉，行$data['country]=$this->home->get_country（）之后没有足够的信息；添加：print_r（$data['country']）；模具（）；输出是什么？感谢您的回答，但它仍然会给我相同的错误消息（ainda não functiona），在加载任何视图之前，添加
var_dump（$data['country'）；退出如果有任何价值在那里，你做我的解决方案错误。如果已定义，则错误不能相同。
