CI multiple image resizing - codeigniter

Question

I'm uplaoding multiple images with CI, they do upload. I am also trying to resize them,
with the following code, only the first image resizes, rest of them don't. They get uploaded with their current size.
What's wrong?
Any help'd be really, really appreciated.
function doupload() {
$path = array();
$count = count($_FILES['userfile']['size']);
foreach($_FILES as $key=>$value){
for($n=0; $n<=$count-1; $n++) {
$_FILES['userfile']['name']=$value['name'][$n];
$_FILES['userfile']['type'] = $value['type'][$n];
$_FILES['userfile']['tmp_name'] = $value['tmp_name'][$n];
$_FILES['userfile']['error'] = $value['error'][$n];
$_FILES['userfile']['size'] = $value['size'][$n];
$config['upload_path'] = './images';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
$this->upload->do_upload();
$data = $this->upload->data();
$path[] = $data['full_path']; //contains full path of every image
}
}
foreach($path as $p=>$ath){
$config1 = array(
'source_image' => $ath,
'new_image' => './images',
'maintain_ration' => true,
'overwrite' => true,
'width' => 600,
'height' => 400
);
$this->load->library('image_lib', $config1);
$this->image_lib->resize();
$this->image_lib->clear();
}
}

Answer 1

first load image_lib outside loop you can use initialize in loop and pass new config for every image
$this->load->library('image_lib');
foreach($path as $p=>$ath){
$config1 = array(
'source_image' => $ath,
'new_image' => './images',
'maintain_ration' => true,
'overwrite' => true,
'width' => 600,
'height' => 400
);
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
}

Answer 2

CodeIgniter's Loader class loads libraries only once, so in your foreach you resize the same image multiple times. Move the library loading out of the loop and use the initialize method of Image Manipulation library to set the config for every resize.

Answer 3

in my case load lib in constructor and use code
$config['image_library'] = 'gd2';
$config['maintain_ratio'] = FALSE;
$config['source_image'] = $config['upload_path'].$image_info['file_name'];
$config['new_image'] = $config['upload_path']."thumb_".$image_info['file_name'];
$config['width'] = 313;
$config['height'] = 303;
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
$config['new_image'] = $config['upload_path']."icon_".$image_info['file_name'];
$config['width'] = 70;
$config['height'] = 70;
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
keep index name always new_image in $config['new_image']
