what wrong with this controller??

I have a controller like this

Code:
&lt;?php

class Test extends Controller

{

    function Test()

    {

        parent::Controller();

    }

    function index() 

    {

    $data['tanggal']    = '';

        $data['email']         = '';

        $data['nama']         = '';

        $data['isi']         = '';

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

    }

    function choose_data($id=0)

        {

        $this->db->where('id_testimonial',$id);

        $query = $this->db->get('testimonial');

        if ($query->num_rows() > 0) 

        {

                $data= $query->row();

        }

        $this->index($data); 

        } 

}

and my view like this

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;testpage&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

&lt;?php

echo $tanggal;

echo '<br />';

echo $email;

echo '<br />';

echo $nama;

echo '<br />';

echo $isi; 

?&gt;

&lt;/body&gt;

&lt;/html&gt;

My problem is why if I call choose_data
by the URL http://localhost/ci2/test/choose_data/15
its didn't display anything??

it won't. index doesn't have anything to produce. your variables do not have anything in them.

try

function index($data) {
// your index method code
}

I try your command
it still display nothing

I think my problem is
index function sets a bunch of variables to ‘’
but if I didn't it
$tanggal
$email
$nama
$isi
will not define..

do you have any idea to fix it??

errr..

you really should read the user_guide.

that's what you need to put if you want to assign it to a variable.

Code:
$data['tanggal'] = $data->yourtablefield;

Do you mean like this

Code:
&lt;?php

class Test extends Controller

{

    function Test()

    {

        parent::Controller();

    }

    function index($data) 

    {

        $data['tanggal']    = $data->tanggal;

        $data['email']         = $data->email;

        $data['nama']         = $data->nama;

        $data['isi']         = $data->isi;

        //Load the URL helper

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

    }    

    function choose_data($id=0)

    {

        $this->db->where('id_testimonial',$id);

        $query = $this->db->get('testimonial');

        if ($query->num_rows() > 0) 

        {

        $data ['tanggal']= $query->row();

        $data ['email']= $query->row();

        $data ['nama']= $query->row();

        $data ['isi']= $query->row();

        }

        $this->index($data); 

    } 

}

its still error

I'm guessing this is a repost? yudahebat, you might want to get your footing in basic PHP scripting. As has been demonstrating, you don't seem to have a problem using the CI framework as much as you do understanding how to move variables around in a script.

I test with http://localhost/ci2/test/choose_data/15
and the result is

Fatal error: Cannot use object of type stdClass as array in C:\xampp\htdocs\CI2\system\application\controllers\test.php on line 11

what is wrong??

yeah, I agree.

yudahebat, you probably don't have those fields in the db.

you can't interexchange objects and arrays, as you are doing in this example:

Code:
&lt;?php

class Test extends Controller

{

    function Test()

    {

        parent::Controller();

    }

    function index($data)

    {

        $data['vars'] = $data;

        //Load the URL helper

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

    }    

    function choose_data($id=0)

    {

        $this->db->where('id_testimonial',$id);

        $query = $this->db->get('testimonial');

        if ($query->num_rows() > 0)

        {

            $data = $query->row();

        }

        $this->index($data);

    }

}

You should either be returning a row as an array with row_array(), or choosing a different variable name.

Code:
&lt;?php

class Test extends Controller

{

    function Test()

    {

        parent::Controller();

    }

    function index($data)

    {

        $page['vars'] = $data;

        //Load the URL helper

        $this->load->view('testpage', $page);    

    }    

    function choose_data($id=0)

    {

        $this->db->where('id_testimonial',$id);

        $query = $this->db->get('testimonial');

        if ($query->num_rows() > 0)

        {

            // changed to row_array()

            $data = $query->row_array();

        }

        $this->index($data);

    }

}
