Codeigniter: resizing multiple uploaded images gets only one image resized - codeigniter

Question

I'm trying to resize all uploaded images uploaded from a form and save a resized copy in another folder. This method works fine with a single image upload not in a multiple image upload. The issue here that I get only 1 image resized. Here's the upload and resize code:
$this->load->library('upload');
$dataInfo = array();
$files = $_FILES;
$cpt = count($_FILES['userfile']['name']);
for($i=0; $i<$cpt; $i++)
{
$_FILES['userfile']['name']= $files['userfile']['name'][$i];
$_FILES['userfile']['type']= $files['userfile']['type'][$i];
$_FILES['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];
$_FILES['userfile']['error']= $files['userfile']['error'][$i];
$_FILES['userfile']['size']= $files['userfile']['size'][$i];
$config = array();
$config['upload_path'] = realpath(APPPATH . '../images/myfolder/');
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '2000';
$config['overwrite'] = FALSE;
$rand_string = $this->generateRandomString(3);
$ext = strtolower(pathinfo($_FILES['userfile']['name'], PATHINFO_EXTENSION));
$filename = round(microtime(true) * 1000).$rand_string.'.'.$ext;
$config['file_name'] = $filename;
$this->upload->initialize($config);
if ($this->upload->do_upload('userfile')) {
$this->resizeImage($filename);
$dataInfo[] = $this->upload->data();
}
}
Resizing function
public function resizeImage($filename)
{
$source_path = realpath(APPPATH . '../images/myfolder/'.$filename) ;
$target_path = realpath(APPPATH . '../images/myfolder/thumbs/') ;
$config_manip = array(
'image_library' => 'gd2',
'source_image' => $source_path,
'new_image' => $target_path,
'maintain_ratio' => TRUE,
'create_thumb' => TRUE,
'thumb_marker' => '',
'width' => 200,
'height' => 200
);
$this->load->library('image_lib', $config_manip);
if (!$this->image_lib->resize()) {
echo $this->image_lib->display_errors();
exit;
}
$this->image_lib->clear();
}
But I get just 1 image resize though all images are uploaded not just one. Why is this happening and how to fix i?

Answer 1

Assuming that all your images are getting uploaded (that is the case right?) then I would suggest trying: $this->upload->initialize($config, true); and:
$this->load->library('image_lib');
$this->image_lib->initialize($config_manip);
if (!$this->image_lib->resize()) {
echo $this->image_lib->display_errors();
exit;
}
