Codeigniter resizing of image not working

Question

I am trying to resize the uploaded image to height of 163px maintaining aspect ratio and then upload it to a folder. I tried with the following code:

$id=1;     // user id
$this->load->library('image_lib');
$filename=$_FILES['file']['name'];
$config['image_library'] = 'gd2';
$config['upload_path'] = './userdata/'.$id;
$config['height'] = '163px';
$config['maintain_ratio'] = TRUE;
//$config['master_dim'] = 'height';
$config['source_image'] = $filename;
$this->load->library('upload', $config);
$this->image_lib->initialize($config);
$this->image_lib->resize();
if(!$this->upload->do_upload('file')) 
{               
     echo $this->data['error'] = $this->upload->display_errors();
}

However this is uploading the image to the correct folder but the image is not resized. I uploaded an image of size *170*128* and it is uploaded to folder as it is without resizing. What is wrong with my code?

Can anyone help me to find the problem?

Thanks in advance.

Does the height need to be in px? Or can you just use '163'? — Craig

Try this cleaner version, the config for height or width doesn't need a px, hence your code is a little bit confusing :

$id = 1;

$config = array(
    'upload_path'   => './userdata/'.$id,
    'allowed_types' => 'gif|jpg|jpeg|png',
    'encrypt_name'  => true,
);

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

$field_name = "file"; // change this with your file upload part's field name if different

if ($this->upload->do_upload($field_name)) {
    $image = $this->upload->data();
    $config = array(
        'image_library'   => 'gd2',
        'source_image' => $image['full_path'],
        'maintain_ratio'  => true,
        'height'  => 163,
     );
     $this->load->library('image_lib', $config);
     if (!$this->image_lib->resize()) {
            echo $this->image_lib->display_errors();
     }
     $this->image_lib->clear();
}

i've tried this in my local and its working, can you check if the gd is installed or enabled with a simple phpinfo() call?

@Burak..I got it working. The problem was I included $this->load->library('image_lib') multiple times..

Simple...

You have to do one thing Go to Captcha_helper.php and search

instead of

    $x = mt_rand(0, $img_width / ($length / 3));

Do Like this

    $x = mt_rand(0, $img_width / ($length / 1));
