pagination part2 (help)

[eluser]sasori[/eluser]
hi, I revised my code and now i am getting this error whenever I click the page 2 and so on
here's my controller class

Code:

function index($page = 0)
    {
      $this->load->library('table');
      $this->load->model('stock_model');
      $stocks = $this->stock_model->getStocks($page);
      if($stocks['query']->num_rows() > 0)
      {
        $table = array();
        $table[] = array("Price Percent_change",
                         "Company Name",
                         "Company Code",
                         "Volume");
        foreach($stocks['query']->result() as $row)
        {
          $table[] = array($row->pricepercent,
                           $row->compname,
                           $row->compcode,
                           $row->volume);
        }
        $data['stocks'] = $table;
      }
      $data['heading'] = "Stocks";
      $this->load->library('pagination');
      $config['base_url'] = 'http://myapp/welcome/stocks_view/';
      $config['total_rows'] = $stocks['total_rows'];
      $config['per_page'] = '5';
      $config['uri_segment'] = 3;
      $this->pagination->initialize($config);
      $data['base'] = $this->config->item('base_url');
      $data['css'] = $this->config->item('css');
      $data['title'] = "Stocks Page";
      $this->load->view('stocks_view',$data);
    }

and now here's my model class

Code:

class Stock_model extends Model
{

    function Stock_model()
    {
      parent::Model();
    }

    function getStocks($page)
    {
      $data = array();
      $this->db->limit(5,$page);
      $query = $this->db->get('stocks');
      $query2 = $this->db->get('stocks');
      $total_rows = $query2->num_rows();
      $data['query'] = $query;
      $data['total_rows'] = $total_rows;
      return $data;
    }
}

and here's my view

Code:

<?php

if(!empty($stocks))
{
    echo $this->table->generate($stocks);
}
echo "<br /><br />".$this->pagination->create_links();


?&gt;

the error was

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\myapp\system\application\models\stock_model.php:2)

404 Page Not Found

The page you requested was not found.

probably got some whitespace at the top of your model class or so, don't know CI well enough yet put that seems to me a common error when you use header(). Could be something echoing out before and not being buffered or again a whitespace somewhere. Suggest a cut-n-paste in notepad++ with all characters on to double check.

--EDIT--

Or it could be in your view now that I think of it, make sure there is nothing above <?php //just a thought

[eluser]sasori[/eluser]
ok thanks, now i removed the white space from my model..one last problem now
is when i click the succeeding page links of the pagination,
i am getting a 404 page not found
this is the url that appears when I click the page "2" link

Code:

http://myapp/welcome/stocks_view/5

my route is set to "welcome" controller
and the base_url of the config file is $config['base_url'] = "http://myapp/"
and the base_url of the index() of my controller is $config['base_url'] = "http://myapp/welcome/stocks_view/"

I wonder what's going on ?

[eluser]John Pantoja[/eluser]
As far as your 404, how are your routes? Using mod_rewrite by chance? Might need to add

Code:

$route['page/(:num)' = "controller/page/$1";

to your config/routes.php if I understand CI as well as I think (just starting)

[eluser]sasori[/eluser]
that doesn't work
my default controller i

Code:

$route['default_controller'] = "welcome";

[eluser]John Pantoja[/eluser]
Sorry, I'm on the wifes netbook so I have a small screen, your $route and I'm not sure how the pagination writes the urls would be

Code:

$route['(:num)'] = "welcome/stock_view/$1";

but this is based on how the url is though, again I don't know this library enough.

[eluser]sasori[/eluser]
yes it doesn't work

[eluser]n0xie[/eluser]

and the base_url of the index() of my controller is $config[‘base_url’] = “http://myapp/welcome/stocks_view/”

What do you mean by this?

Your code only shows function index(). I don't see a function stocks_view().

[eluser]John Pantoja[/eluser]
AH I see said the deaf man, I looked at the config lines, I would suggest you refactor and have a controler for pages so your url would be like

Code:

/page/:num

If I gather correctly it's bases off of

Code:

$config['base_url'] = 'http://myapp/welcome/stocks_view/';
$config['uri_segment'] = 3;

so I would change it to

Code:

$config['base_url'] = 'http://myapp/page/';
$config['uri_segment'] = 3; //not sure what this does consult user guide

or to something of that fact. You'll need a new controller and modify the route accordingly
