CodeIgniter通过URL进行动态数据库连接

问题描述：

I need to connect to a DB that's name will be entered in the URL. For Example the URL will be

http://my_url.com/comp/login

So the DB I need to connect to is 'comp'.

Is there a way to do this without defining each database in the database.php config file?

something like

define('COMP', $this -> uri -> segment(1));

and then

'database' => 'tm_'.COMP,

The above gives me an error about the $this, so I am not completely sure where I can define the COMP variable where the database config file can read it.

Thanx

我需要连接到一个名称将在URL中输入的数据库。例如，URL将是 nn

http://my_url.com/comp/login

我需要连接的数据库是'comp '。 p>

有没有办法在不定义database.php配置文件中的每个数据库的情况下执行此操作？ p>

类似 p> \ n

  define（'COMP'，$ this  - ＆gt; uri  - ＆gt; segment（1））; 
  code>  pre> 
 
 然后 
 
 
 'database'=＆gt;  'tm _'。COMP，
  code>  pre> 
 
 上面给出了一个关于$ this的错误，所以我不能完全确定在哪里可以定义COMP变量所在的数据库 配置文件可以读取它。 p> 
 
 
 Thanx  p> 
  div>

答

Was missing this part :

$CI =& get_instance();

and updated the

define('COMP', $this -> uri -> segment(1));

define('COMP', $CI -> uri -> segment(1));

is working now
