检查代码信号查询错误，而不是向用户显示它们 [英] Check codeigniter query errors instead of showing them to the user

问题描述

如何检查查询是否出错，而不是向用户显示错误（包含不安全的数据库信息）。

How can I check if a query went wrong instead of showing errors to users (containing database info which is unsafe).

假设我有这样的情况，分页类需要一个URI段来显示页面
example.com/page/uri_segment 。如果有人写这样 example.com/page/bla_bla_bla 我得到一个错误，显示有关我的数据库的信息。

Let's say I have such situation where my paging class takes a URI segment to show page example.com/page/uri_segment. If someone write it like this example.com/page/bla_bla_bla I get an error that shows information about my database.

如何处理此问题？

推荐答案

/database.php set

In application/config/database.php set

// suppress error output to the screen
$db['default']['db_debug'] = FALSE;

在您的模型或控制器中：

In your model or controller:

// try the select.
$dbRet = $this->db->select($table, $dataArray);
// select has had some problem.
if( !$dbRet )
{
   $errNo   = $this->db->_error_number()
   $errMess = $this->db->_error_message();
   // Do something with the error message or just show_404();
}
