I'mtrying to set up a Table Model so that I can change which tables I'm using for the whole application. I have a prefix on some of my tables so I'm trying to do this:

Code:
&lt;?php

class Table_model extends Model

{

    /* Set up Table Aliases

    --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- */

    var $_prefix = 'beta_';

    var $_user = $_prefix.'user';

    var $_profile = $_prefix.'user_profile';

...etc.

But I get an error:

Quote:Parse error: syntax error, unexpected T_VARIABLE in /home/insub2/Websites/CV_Test/system/application/models/table_model.php on line 8

You can't do that when declaring variables, add prefix in your constructor instead:

Code:
&lt;?php

class Table_model extends Model

{

    /* Set up Table Aliases

    --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- */

    var $_prefix = 'beta_';

    var $_user = 'user';

    var $_profile = 'user_profile';

    function __construct()

    {

        parent::__construct();

        $this->_user = $this->_prefix . $this->_user;

        $this->_profile = $this->_prefix . $this->_profile ;

    }

Thanks. But why is that? ...just curious.

It's just how PHP works, it's not related to CodeIgniter.
