When a user uploads a file I require multiple thumbnails with different dimensions to be created, I'm trying to achieve this using the following code in a model:
Code: function create_thumb($file)
{
// Image resizing config
$config = array(
// Concept Page
array(
'image_library' => 'GD2',
'source_image' => 'uploads/'.$file,
'create_thumb' => TRUE,
'maintain_ratio'=> TRUE,
'width' => 632,
'height' => 451
),
// Workspace Page
array(
'image_library' => 'GD2',
'source_image' => 'uploads/'.$file,
'create_thumb' => TRUE,
'maintain_ratio'=> FALSE,
'thumb_marker' => '_ws_thumb',
'width' => 184,
'height' => 184
),
// Dashboard Page
array(
'image_library' => 'GD2',
'source_image' => 'uploads/'.$file,
'create_thumb' => TRUE,
'maintain_ratio'=> FALSE,
'thumb_marker' => '_db_thumb',
'width' => 244,
'height' => 244
));
foreach ($config as $item)
{
$this->load->library('image_lib', $item);
if(!$this->image_lib->resize())
{
return false;
}
$this->image_lib->clear();
}
}
When I call this function, it only create the first thumbnail in the array (The first sub-array, it skips the second and third sub-array). Any idea why this is happening?

because the library is only loaded once, what you want to be doing is
Code: $this->load->library('image_lib', $config[0]);
foreach ($config as $item)
{
$this->image_lib->initialize($item);
if(!$this->image_lib->resize())
{
return false;
}
$this->image_lib->clear();
}
load the library with any old config but when you loop round and want to use the library then re-initialise the config settings.

Thanks for the solution, I actually found another way round it as well.
I skipped the $this->image_lib->initialize() function from the manual, instead of loading the library all the time you use initialize() to load up your configs. I updated my code using this function and it works perfectly fine!

This is great and totally helped me. Here is my full working controller for anyone that needs it for reference:
Code: <?php
class Upload extends Controller {
function Upload() {
parent::Controller();
}
function index() {
$this->load->view('upload_form');
}
function doUpload() {
$config['upload_path'] = 'uploads/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '1000';
$config['max_width'] = '1600';
$config['max_height'] = '1280';
$this->load->library('upload', $config);
if(!$this->upload->do_upload()) echo $this->upload->display_errors();
else {
$fInfo = $this->upload->data();
$this->_create_thumbs($fInfo['file_name']);
$data['uploadInfo'] = $fInfo;
$data['lg_thumbnail_name'] = $fInfo['raw_name'] . '_lg_thumb' . $fInfo['file_ext'];
$data['sm_thumbnail_name'] = $fInfo['raw_name'] . '_sm_thumb' . $fInfo['file_ext'];
$this->load->view('upload_success', $data);
}
}
function _create_thumbs($file_name) {
// Image resizing config
$config = array(
// Lg Thumb
array(
'image_library' => 'GD2',
'source_image' => 'uploads/'.$file_name,
'create_thumb' => TRUE,
'maintain_ratio'=> TRUE,
'thumb_marker' => '_lg_thumb',
'width' => 400,
'height' => 600
),
// Sm Thumb
array(
'image_library' => 'GD2',
'source_image' => 'uploads/'.$file_name,
'create_thumb' => TRUE,
'maintain_ratio'=> TRUE,
'thumb_marker' => '_sm_thumb',
'width' => 75,
'height' => 75
));
$this->load->library('image_lib', $config[0]);
foreach ($config as $item)
{
$this->image_lib->initialize($item);
if(!$this->image_lib->resize())
{
return false;
}
$this->image_lib->clear();
}
}
}
I am a newbie and was able to build this with help from this forum post and this tutorial: http://net.tutsplus.com/videos/screencas...deigniter/
