bypass controller and modify headers for flv output

Posted by: El Forum - 09-29-2008, 05:54 AM - Replies (3)

[eluser]alectrash[/eluser]
I want to have on my site the url

www.mydomain.com/video/view/a-lake

which upon being requested basically does this

Code:
//query db to get filename and filesize where file id is "a-lake" (simple)

      echo 'header("Content-Type: video/x-flv")';

      echo 'header("Content-Disposition: attachment; filename="' . $filename . '")';

      echo 'header("Content-Length: "' . $filesize .')';

When this is working in another file I want to send the url to a jeroenwijering player like so:

Code:
...

  s1.addVariable("file", encodeURIComponent(http://www.mydomain.com/video/a-lake));

...

I am storing videos above root directory hence why i'm doing it this way.

I tried creating a controller video with function view which output the headers but they just came out as text. I looked at kaging but to no avail.

I tried looking at hooks but dont know if thats right place to look?

hello,

I have a problem with uri->segment() object in my web application.

This is my url

Code:
/index.php/account/d41d8cd98f00b204e9800998ecf8427e

Where account is class Account extends Controller and index() function get uri element... but, doesn't work!

Code:
404 Page Not Found

The page you requested was not found.

This is my error: 404 not found!?!

For simple example, this is my code:

Code:
function index()

    {

        if($this->uri->segment(2) == 'd41d8cd98f00b204e9800998ecf8427e')

        {

            echo "Ok";

        }

    }

Where is the problem???

Thanks Wink

PS. I wanna comparate session_id (in login file) with account/session_id in account class Wink

AR library : remove cache methods?

Posted by: El Forum - 09-29-2008, 03:45 AM - Replies (2)

[eluser]xwero[/eluser]
Lately i'm beginning to wonder if there is the real benefit when using the cache methods?

A lot of people use the cache methods when they have to get two different things from the same table like the number of rows and the rows themselves but most of the times the num_rows method is sufficient.

Instead of the cache methods i'm starting to use arrays and variables for not having to redefine the sql statement parts.

Code:
$this->db->start_cache();

$this->db->from('table');

$this->db->where(array('id'=>1,'time'=>'12:00:00'));

$this->db->stop_cache();

$this->db->select('number');

$query1 = $this->db->get();

$this->db->select('name');

$query2 = $this->db->get();

$this->db->flush_cache();

// VS

$table = 'table';

$where = array('id'=>1,'time'=>'12:00:00');  

$this->db->select('number');

$this->db->from($table);

$this->db->where($where);

$query1 = $this->db->get();

$this->db->select('name');

$this->db->from($table);

$this->db->where($where);

$query2 = $this->db->get();

Normally i'm not found on copying lines but once the queries are getting more complex i noticed the cache methods are more in the way than helping to reduce the code i have to write. Not adding the flush_cache method caused me a lot of time loss. When using variables and arrays you don't have to flush the DB object values.

What is your view on the cache methods?

mlogin.php code:

Code:
&lt;?php

    class Mlogin extends Model

    {

        function __Construct()

        {

            parent::Model();

        }

        function get_users($username)

        {

            $this->load->database();

            $this->db->select('Username_VC');

            $this->db->from('Users_T');

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

            return $query->row();

        }

        function get_last_ten_entries()

        {

            $this->load->database();

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

            return $query->result();

//            print $query->num_rows();

        }

        function check_login_data($username, $password)

        {

            if($query->num_rows() > 0)

            { return $query->result(); }

            else

            { return false;}

        }

    }

    function addUsersHistory(){

      $now = date("Y-m-d H:i:s");

      $data = array( 

        'Username' => $this->input->xss_clean($this->input->post('username')),

        'RemoteAddr_VC' => $this->input->ip_address(),

        $data['base']       = $this->config->item('base_url'); 

        $data['css']        = $this->config->item('css');        

        $this->load->helper(array('form', 'url'));        // load form 

        $this->load->library('validation'); // load validations

              $rules['username'] = 'trim|required|max_length[12]|xss_clean|callback__check_logindata';

              $rules['password'] = 'trim|required|md5';

            // set values for repopulating fields

            $fields['username']='Username';

            $fields['password']= 'Password ';

            $this->validation->set_fields($fields);

              $this->validation->set_rules($rules);

        if ($this->validation->run() == TRUE)

        {            

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

            $this->load->model('Mlogin','',TRUE);

            $password = $this->validation->password;

            $username = $this->validation->username;

            if ($this->Mlogin->check_login_data($username, $password) == FALSE)

            {

                $this->validation->set_message('_check_logindata', 'Username and Password might be incorrect!');

                return FALSE;

            }

//            $this->Mlogin->addHistory();

           // redirect('welcome/thankyou','refresh');

        }

        else

        {

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

在sql裡面不能加雙引號嗎?
但是不加雙引號postgresql確無法判別大小寫之分
這該怎麼辦阿?

Codeigniter that suitable for PHP 6

Posted by: El Forum - 09-28-2008, 10:38 PM - Replies (7)

[eluser]chandrajatnika[/eluser]
I have some problem about my CI application when I install it on PHP 6.
this is some error:

Code:
Deprecated: Assigning the return value of new by reference is deprecated in J:\\Webmaster_File\\Project\\product_database\\system\\codeigniter\\Common.php on line 123

Deprecated: Assigning the return value of new by reference is deprecated in J:\\Webmaster_File\\Project\\product_database\\system\\codeigniter\\Common.php on line 129

Fatal error: Call to undefined function set_magic_quotes_runtime() in J:\\Webmaster_File\\Project\\product_database\\system\\codeigniter\\CodeIgniter.php on line 53

I remove \"Call Time Pass by Reference\" on Common.php by remove \"&\" on object declaration

Code:
$obj =& new Class(); // before

 $obj = new Class(); // after

I remark \"set_magic_quotes_runtime()\" statement from CodeIgniter.php, and the last is i create my own \"get_magic_quotes_gpc()\" function by only returning a boolean false.

After that, my application do unfinish looping and my web server got some error.

Could you please help me how to handle this?
