Hiya,

I am a dub for the php and I just test the CI through the video tutorials.

I have a problem is that why my browser display nothing when I set
$autoload['libraries'] = array('database');
in autoload.php.

and if not to set it, there is a error message, which looks like

Code:
A PHP Error was encountered

Severity: Notice

Message: Undefined property: Testdb::$db

Filename: controllers/testdb.php

Line Number: 13

Thx

Without seeing any code the things I would check are:

- Is your database connection info correct?
- Does the user specified in your db connection info have necessary db permissions?
- Are there any syntax errors that would cause a fatal error and a blank page on a setup where display_errors is set to Off in php.ini?

If you post the code that is causing problems, we may be able to help you better.

Thanks bradym.

I am sure my database connection info is right and display_errors was set to ON.

My code is simply:

Code:
&lt;?php

class Testdb extends Controller{

    function Testdb()

    {

        parent::Controller();

    }

    function index()

    {

        $data['title'] = 'Test Database for ColetEstate';

        $data['query'] = $this->db->get('landlord');

        $this->load->view('testdb_view', $data);

    }

}

?&gt;

/config/autoload.php:

Code:
$autoload['libraries'] = array('database');

/config/database.php

Code:
$active_group = "default";

$db['default']['hostname'] = "localhost";

$db['default']['username'] = "root";

$db['default']['password'] = "";

$db['default']['database'] = "coletestate";

$db['default']['dbdriver'] = "mysql";

$db['default']['dbprefix'] = "";

$db['default']['active_r'] = TRUE;

$db['default']['pconnect'] = TRUE;

$db['default']['db_debug'] = TRUE;

$db['default']['cache_on'] = FALSE;

$db['default']['cachedir'] = "";

BTW,
I imitate the video tutorial to build the simply blog but
there are also noting to display when I set $route['scaffolding_trigger'] = "scaffolding" in /config/routes.php

You need to enable scaffolding, take a look at http://ellislab.com/codeigniter/user-guide/general/scaffolding.html.

Hmm.. The only thing that jumps out at me is the <boyd> instead of <body>, but I'm not convinced that's the real problem. I'm guessing there's an issue with the database, but that's a complete guess cause I can't see anything else wrong.

Hopefully someone else will be able to give some helpful hints.

Sorry I can't be more helpful.

Blank pages are almost always due to PHP errors, only the server is suppressing the error. Try the instructions on this page and if nothing still happens, you may need to contact your host.

Check you database.php config file for blank spaces before <? or after ?>.

For me, the problem was caused from not having the php4-mysql module installed and configured. Are you working on your own host, or shared hosting?
