Can't create thumbs using Image Manipulation class

[eluser]chitoso[/eluser]
Hi all, I've been reading the docs and trying everything to make thumbs out of uploaded images but I can't seem to find the problem.

Images are uploaded and saved correctly but thumbs are not, it fails with no error output.
This is the code I'm using:

Code:

$data = $this->upload->data();

$config_image['image_library'] = 'gd';
$config_image['source_image'] = $data['full_path'];
$config_image['new_image'] = 'uploads/thumbs/';
$config_image['create_thumb'] = TRUE;
$config_image['maintain_ratio'] = TRUE;
$config_image['width'] = 750;
$this->load->library('image_lib', $config_image);

if ( !$this->image_lib->resize())
{
    $this->session->set_flashdata('message',  $this->image_lib->display_errors());
}

Also, I want to resize images to fit max-width=750, but maintain the ratio. Is what I'm doing correct to achive that?
Thanks in advance!

Hey all, I've succesfully developed my first project with CI and I'm really happy with it.
One minor problem though, I've come across this issue again and I can't really get around it.

Does anyone have a clue on this matter?

I'd rather manage this using CI and not an external script like timthumb.
Thanks.

You need to set the config var ['new_image'] to an actual file, not just the directory. Also that directory needs to be absolute/relative server path.

rom what I've seen in the docs (http://ellislab.com/codeigniter/user-gui...e_lib.html):
"If only the path is specified, the new image will be placed in the destination with the same name as the original.", so I assume this code should work.

Code:

$config_image['image_library'] = 'gd';
$config_image['source_image'] = $data['full_path'];
$config_image['new_image'] = 'uploads/proyectos/thumbs/';
$config_image['create_thumb'] = TRUE;
$config_image['maintain_ratio'] = TRUE;
$config_image['width'] = 120;

$this->load->library('image_lib', $config_image);

if (!$this->image_lib->resize()) {
    $this->session->set_flashdata('message', $this->image_lib->display_errors());
}

The weird thing is that it fails silently, no errors whatsoever. Any clues?

Thats really strange that there are no errors in the log or coming from display_errors().

Have you checked permissions?

It appears otherwise that you are doing it by the book so without any more info I can't really think of anything that would solve your issue.

[eluser]chitoso[/eluser]
Thanks anyway. If I get around it I'll make sure to post it For now, timthumb it is.

Hi all,
I hate to revive this thread, but I'm constantly facing this problem in CI and it's really frustrating me

Does anyone have a clue on why this might be happening or at least some help to troubleshoot this?

Thanks a million.

Try this for testing purposes:

Code:

// replace this...
if (!$this->image_lib->resize()) {
    $this->session->set_flashdata('message', $this->image_lib->display_errors());
}

// with this..
$this->image_lib->display_errors();

If you still get nothing ensure that the image is passing properly from the form. Maybe map a static test image from your folder and see if you're generating a thumbnail like that with your script.

I've followed both your recommendations but it just fails silently.
