[eluser]j0hn[/eluser]
im encountering problems in creating thumbnails using image_lib. can anyone help me on this...

the error shows like this:

Quote:The path to the image is not correct
Your server does not support the GD function required to process this type of image.

and my code is like this:

Code:
class Dummy extends Controller

{

    function Dummy()

    {

        parent::Controller();

        $this->load->library('layout', 'layout_main');

        $this->load->library(array('image_lib'));

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

    }

    function index()

    {

        $data['title_for_layout'] = "test";

        $config['image_library'] = 'GD';

        $config['source_image'] = './images/asia2007thailanderawanredux/photo1.jpg';

        $config['create_thumb'] = true;

        $config['maintain_ratio'] = true;

        $config['width'] = '75';

        $config['height'] = '50';

        $this->image_lib->initialize($config);

        if (!$this->image_lib->resize()) {

            echo $this->image_lib->display_errors();

        }

        $this->layout->view('home', $data);

    }

}

my directory structure is like this:

Code:
|-- system

    |-- application

        |-- controllers

        |-- images

            |-- asia2007thailanderawanredux

* how can i correct my image path in my code using my directory structure?
* have a gd bundled (2.0.34 compatible)installed but im still getting error: server does not support gd.

XSS Protection Problem - it blocks the page

Posted by: El Forum - 09-09-2007, 11:11 PM - No Replies

[eluser]xcristi[/eluser]
Hello,

Well, I turn on the XSS protection in CI configuration for automatic clean up. When I enter something nasty in a textarea, the filtering seems to work (?) but I get only a blank page as a result. The error thrown in logs is:

Code:
PHP Fatal error:  Call to undefined function:  get_instance() in /home/html/soimul/system/libraries/Input.php on line 855

I turn off this feature and try with some manual clean up ($this->input->post('field', 'true')) and it works very well. I can go on and use it this way, but it will be more convenient to do it automatically.

What do you think it's wrong in the first case?
Thanks.

File helper

Posted by: El Forum - 09-09-2007, 08:25 PM - No Replies

[eluser]latuss[/eluser]
Hi all...
I'm working with files... the write_file works fine.. but.. how can I delete a file?
I try with the

Code:
$file_delete = '/var/www/xmlrpc/listas/'.$nombre_lista.".txt";

delete_files($file_delete);

but does not work... so.. I try with the unlink

Code:
$file_delete = '/var/www/xmlrpc/listas/'.$nombre_lista.".txt";

unlink($file_delete);

and does not work either.. the file was created by the write_file method of the file helper...

any ideas?

Bye Smile

SOLVED: where are my $_FILES

Posted by: El Forum - 09-09-2007, 04:10 PM - No Replies

[eluser]vevmesteren[/eluser]
Good evening all

I am starting to get seriousely desperate here. A form that was working perfectly fine stopped working. And I cannot for the life of it, figure out why that is. I am running the last version of CI. I have a form (normally it is huuge, but in an effort to find out wtf is wrong I have cut it down a lot.

Code:
&lt;?=form_open_multipart('inscription/addUser'); ?&gt;

 <tr>

    <td colspan='2'>Files</td>

</tr>

<tr>

    <td>Some data: </td>

    <td>

&lt;input type="file" name="audiofile" size="20"&gt;</td>

</tr>

<tr>

    <td colspan='2'>&lt;input type="submit"&gt;</td>

</tr>

&lt;/form&gt;

when I then

Code:
var_dump($_FILES)

I get zilch, nada nothing. As in:

Code:
array(0) { }

. Why is that? It was working perfectly fine before.

oh yes before I forget here my library load script:

Code:
$config['upload_path'] = './uploads/';

            $config['allowed_types'] = 'jpg|mp3|avi|mov|m4a';

            $config['remove_spaces'] = TRUE;

            $config['max_size'] = '1000000';

            $this->load->library('upload', $config);

PHP info tells me that file_uploads are 'on'

Wrong result of length validation when using russian and utf-8

Posted by: El Forum - 09-09-2007, 03:27 PM - No Replies

	[eluser]Unknown[/eluser] The case is simple: When I input 10-letters word in the field and set max_length[20] for it, it validates. And when there's 11-letters word, validator raises an error "The title field can not exceed 20 characters in length.", that is certainly wrong. I suppose, the reason is that utf-8 is two-byte encoding.

Possible Image Lib bug?

Posted by: El Forum - 09-09-2007, 02:21 PM - No Replies

[eluser]jstrebel[/eluser]
Is this a bug or am I just not getting it: I upload an image, resize it to $x1,$y1 then thumbnail it to $x2,$y2. So i should have 2 images.. one called image.jpg and another called image_thumb.jpg.

Code:
//$path= path to file, $x,$y are size demisions

function _image_resize ($path,$x1,$y1,$x2,$y2)

        {

                        $this->image_lib->clear();

                        //resize Image

                        $config['image_library'] = 'GD2';

                        $config['source_image'] = $path;

                        $config['width'] = $x1;

                        $config['height'] = $y1;

                        $config['master_dim'] = 'auto';

                        $config['quality'] = '100%';

                        $this->image_lib->initialize($config);

                        $this->image_lib->resize();

                        $this->image_lib->clear();

                        //thumbnail the image just resized

                        $config2['image_library'] = 'GD2';

                        $config2['source_image'] = $path;

                        $config2['width'] = $x2;

                        $config2['height'] = $y2;

                        $config2['master_dim'] = 'auto';

                        $config2['quality'] = '100%';

                        $config2['create_thumb'] = TRUE;

                        $this->image_lib->initialize($config2);

                        $this->image_lib->resize();

        }

What I am actually getting from this function is 1 image called image.jpg (no _thumb) sized to $x2,$y2 (the thumbnail specs). Any thoughts?

Complex DB query using CI helpers

Posted by: El Forum - 09-09-2007, 01:46 PM - No Replies

[eluser]Guillem[/eluser]
I have a table (altas) in my db with some foreign keys to other fields of other tables (clientes, estados, usuarios):

Quote:id
id_usuario => usuarios->id
id_estado => estados->id
id_cliente => clientes->id
...

I was trying to use the helpers of CI, since I'd like to make a query with some values that might be entered into a form. My code is that:

Code:
$this->db->select('u.usuario, c.id as cid, c.apellidos, c.nombre, c.dni, e.estado, a.id, a.fecha, a.comentario, a.linea');

if ($this->session->userdata('nivel')>1) {

    if ($_POST['usuario'] != 0) { $this->db->where('a.id_usuario',$_POST['usuario']); }

}

if ($_POST['operadora'] != 0) { $this->db->where('a.id_operadora',$_POST['operadora']); }

if ($_POST['desde'] != null) {         

    $a = explode("/",$_POST['desde'],3);

    $this->db->where('a.fecha >=',mktime(0,0,0,$a[1],$a[0],$a[3]));

}

if ($_POST['hasta'] != null) {         

    $a = explode("/",$_POST['hasta'],3);

    $this->db->where('a.fecha <=',mktime(24,59,59,$a[1],$a[0],$a[3]));

            }

if ($_POST['estado'] != 0) { $this->db->where('a.id_estado',$_POST['estado']); }

$this->db->where('u.id','a.id_usuario');

$this->db->where('c.id','a.id_cliente');

$this->db->where('e.id','a.id_estado');

$this->db->orderby('a.fecha','asc');

$data['altas'] = $this->db->get('altas a, clientes c, usuarios u, estados e');

It seemed it worked fine until I added this 3 lines:

Code:
$this->db->where('u.id','a.id_usuario');

$this->db->where('c.id','a.id_cliente');

$this->db->where('e.id','a.id_estado');

What I was trying to do is to generate a query similar to this:

Code:
$this->db->query("SELECT u.usuario, c.id as cid, c.apellidos, c.nombre, c.dni, e.estado, a.id, a.fecha, a.comentario, a.linea FROM altas a, usuarios u, estados e, clientes c WHERE a.id_usuario='".$_POST['usuario']."' AND a.id_operadora='".$_POST['operadora']."' AND a.fecha>='".$_POST['desde']."' AND a.fecha<='".$_POST['hasta']."' AND a.id_estado='".$_POST['estado']."' AND u.id=a.id_usuario AND c.id=a.id_cliente AND e.id=a.id_estado ORDER BY a.fecha DESC");

I'm really a pretty newbie in CI development, so I'm quite confused about what to do, since this seems quite coherent for me, but the query shows nothing with the helpers and data if I run it manually.

Can any body make me see the light, please?

Thank you all folks Smile
