Multiple thumbnails at once in CodeIgniter - codeigniter

Question

At the moment at once I'm learning and trying, to what CodeIgniter is able to. But I stuck at multiple thumbnails making at once. Probably, I messed up my head too much using Wordpress, and trying to do something like this in Codeigniter, but anyways, here is my code
<?php
class Gallery_model extends CI_Model {
var $gallery_path;
function __construct() {
parent::__construct();
$this->load->helper('functions');
$this->gallery_path = realpath(APPPATH . '../uploads');
}
function do_upload() {
$config = array(
'allowed_types' => 'jpg|jpeg|gif|png',
'upload_path' => $this->gallery_path,
'max_size' => 2000
);
$this->load->library('upload', $config);
$this->upload->do_upload();
$image_data = $this->upload->data();
$image_sizes = array(
'thumb' => array(150, 100),
'medium' => array(300, 300),
'large' => array(800, 600)
);
foreach ($image_sizes as $resize) {
$config = array(
'source_image' => $image_data['full_path'],
'new_image' => $this->gallery_path . '-' . $resize[0] . 'x' . $resize[1],
'maintain_ration' => true,
'width' => $resize[0],
'height' => $resize[1]
);
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
}
}
At the moment, I'm able to create just an image it self, but I cant make thumbnails with this. Maybe someone could enhance the code, and get it work :)
PS - I tried just take everything after $image_sizes, put it in other independent php file, run it, and var dump the $config inside of foreach, and it seemed like working.

Use it like this:
$this->load->library('image_lib');
foreach ($image_sizes as $resize) {
$config = array(
'source_image' => $image_data['full_path'],
'new_image' => $this->gallery_path . '-' . $resize[0] . 'x' . $resize[1],
'maintain_ration' => true,
'width' => $resize[0],
'height' => $resize[1]
);
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
}
initialize works better than loading the library with the $config.

I Solved It.
I Create this function to create Multiple Thumbnails:
function _create_thumbs($file_name){
// Image resizing config
$config = array(
// Large Image
array(
'image_library' => 'GD2',
'source_image' => './assets/images/'.$file_name,
'maintain_ratio'=> FALSE,
'width' => 700,
'height' => 467,
'new_image' => './assets/images/large/'.$file_name
),
// Medium Image
array(
'image_library' => 'GD2',
'source_image' => './assets/images/'.$file_name,
'maintain_ratio'=> FALSE,
'width' => 600,
'height' => 400,
'new_image' => './assets/images/medium/'.$file_name
),
// Small Image
array(
'image_library' => 'GD2',
'source_image' => './assets/images/'.$file_name,
'maintain_ratio'=> FALSE,
'width' => 100,
'height' => 67,
'new_image' => './assets/images/small/'.$file_name
));
$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();
}
}
And then, I call that function when I upload the image like this:
function do_upload(){
$config['upload_path'] = './assets/images/'; //path folder
$config['allowed_types'] = 'gif|jpg|png|jpeg|bmp';
$config['encrypt_name'] = TRUE;
$this->upload->initialize($config);
if(!empty($_FILES['filefoto']['name'])){
if ($this->upload->do_upload('filefoto')){
$img = $this->upload->data();
//Compress Image
$this->_create_thumbs($img['file_name']);
$title = $this->input->post('title',TRUE);
$image_large = $img['file_name'];
$image_medium = $img['file_name'];
$image_small = $img['file_name'];
$this->upload_model->insert_images($title,$image_large,$image_medium,$image_small);
}else{
echo $this->upload->display_errors();
}
}else{
echo "image is empty or type of image not allowed";
}
}
