Files not getting stored in correct folder - php

Question

I have a form in CodeIgniter that allows the user to upload 2 separate files. At the backend I want these files to get stored in the different folder. In the controller i have written the upload code
public function upload()
{
/**Start uploading file**/
$config['upload_path'] = './assets/file/.';
$config['allowed_types'] = 'gif|jpg|png|doc|txt';
$config['max_size'] = 1024 * 8;
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
if (!$this->upload->do_upload('file'))
{
$error = array('error' => $this->upload->display_errors());
echo $error;
}
else
{
$data = $this->upload->data();
echo $file = $data['file_name']; //name of file
}
/**End uploading file**/
/**Start uploading img**/
$config2['upload_path'] = './assets/img/.';
$config2['allowed_types'] = 'gif|jpg|png|doc|txt';
$config2['max_size'] = 1024 * 8;
$config2['encrypt_name'] = TRUE;
$this->load->library('upload', $config2);
if (!$this->upload->do_upload('img'))
{
$error1 = array('error' => $this->upload->display_errors());
echo $error1;
}
else
{
$data1 = $this->upload->data();
echo $img = $data1['file_name']; //name of img
}
/**End uploading img**/
}
The images are getting uploaded but they are getting uplaoded to same folder. Can anyone please tell how i can make the files get saved in seperate folders

Answer 1

in the second load , you need to initialiaze the loaded library because the load method don't initialize it :
$this->upload->initialize($config2);
