Upload multiple files in CodeIgniter not work - php

Question

in my CodeIgniter project I'm uploading files during the project creation. Here's the uploading function:
public function addProcess()
{
echo 'test';
if($this->input->server('REQUEST_METHOD') === 'POST')
{
$this->form_validation->set_rules('album', 'Album', 'trim|required|callback_check_select', 'xss_clean');
if ($this->form_validation->run() === FALSE)
{
$data['albums'] = $this->album_model->albumList();
$this->adminTheme('admin/addSong',$data);
}
else
{
$error = 0;
$this->load->library('upload');
$total_count_of_files = count($_FILES['userfile']['name']);
$album = $this->input->post('album');
$songs = $this->input->post('song');
$artist = $this->input->post('artist');
for($i=0; $i< $total_count_of_files; $i++)
{
if(!$songs[$i])
$songs[$i] = "Track-".($i+1);
if(!$artist[$i])
$artist[$i] = " ";
$_FILES['file']['name'] = $_FILES['userfile']['name'][$i];
$_FILES['file']['type'] = $_FILES['userfile']['type'][$i];
$_FILES['file']['tmp_name'] = $_FILES['userfile']['tmp_name'][$i];
$_FILES['file']['error'] = $_FILES['userfile']['error'][$i];
$_FILES['file']['size'] = $_FILES['userfile']['size'][$i];
$config['upload_path'] = './upload/';
$config['allowed_types'] = 'jpg|jpeg|gif|png|mp3';
$config['max_size'] = '0';
$config['overwrite'] = FALSE;
$config['encrypt_name'] = TRUE;
$this->upload->initialize($config);
if($this->upload->do_upload('file'))
{
$msg = $this->upload->data();
$name = $msg['file_name'];
$error += 0;
$this->song_model->add($songs[$i], $artist[$i], $name, $album);
}else{
$errorStr[] = "$songs[$i] Upload Faild";
$error += 1;
}
}
//$this->album_model->add();
if($error == 0)
{
//$this->msg('admin/song','Successfully added..Redirecting now...');
}
else
{
$this->msg('admin/song','Successfully added..Redirecting now...');
}
}
}
else
{
redirect('admin/album');
}
}
another function for doupload
public function do_upload()
{
$upload_path_url = base_url().'uploads/';
$config['upload_path'] = FCPATH.'uploads/';
$config['allowed_types'] = 'jpg|jpeg|gif|png|mp3';
$config['max_size'] = '30000';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload()) {
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload', $error);
} else {
$data = $this->upload->data();
$info->name = $data['file_name'];
$info->size = $data['file_size'];
$info->type = $data['file_type'];
$info->url = $upload_path_url .$data['file_name'];
$info->thumbnail_url = $upload_path_url .$data['file_name'];
$info->delete_url = base_url().'upload/deleteImage/'.$data['file_name'];
$info->delete_type = 'DELETE';
if (IS_AJAX) {
echo json_encode(array($info));
} else {
$file_data['upload_data'] = $this->upload->data();
$this->load->view('admin/upload_success', $file_data);
}
}
}
my form code
<div id="container">
<h2>Song Name - Add New</h2>
<div class="error">
<?php echo validation_errors(); ?>
</div>
<?php $attributes = array('id' => 'myform'); ?>
<?php echo form_open_multipart('admin/song/addProcess',$attributes); ?>
<div class="line">
<label style="width: 160px;">Album:</label>
<select class="category" name="album" style="width: 280px;">
<option value="select">Select Album</option>
<?php foreach($albums as $album): ?>
<option value="<?php echo $album['id']; ?>">
<?php echo $album['root_name']." --> ".$album['category_name']." --> ".$album['album_name']; ?></option>
<?php endforeach ?>
</select>
<input class="form-submit" style="margin-top: 6px;" type="button" id="more_fields" onclick="add_fields();" value="Add More" />
</div>
<!--end line-->
<div id="nameFields">
<div class="line">
<input type="text" name="song[]" class="input1" style="width: 180px;" placeholder="Song Name" />
<input type="text" name="artist[]" class="input1" style="width: 180px;" placeholder="Artist Name" />
<input type="file" name="userfile[]" class="category" style="width:80px;" />
</div>
<!--end line-->
</div>
<input type="submit" value="Save" class="form-submit" style="margin-right: 180px;" />
</form>
</div>
<!--end container-->
<script type="text/javascript">
function add_fields() {
document.getElementById('nameFields').innerHTML += "<div class='line'><input type='text' name='song[]' class='input1' style='width: 180px;' placeholder='Song Name' /><input type='text' name='artist[]' class='input1' style='width: 180px;' placeholder='Artist Name' /><input type='file' name='userfile[]' class='category' style='width:80px;' /></div>";
}
</script>
However this does not do anything. The files are not being uploaded. Even an empty directory is not being created. Could anybody help me to find the error?
Thanks.

In your addProcess code, remove below code
$_FILES['file']['name'] = $_FILES['userfile']['name'][$i];
$_FILES['file']['type'] = $_FILES['userfile']['type'][$i];
$_FILES['file']['tmp_name'] = $_FILES['userfile']['tmp_name'][$i];
$_FILES['file']['error'] = $_FILES['userfile']['error'][$i];
$_FILES['file']['size'] = $_FILES['userfile']['size'][$i];
and try
foreach ($_FILES as $fieldname => $fileObject)
{
if (!empty($fileObject['name']))
{
$this->upload->initialize($config);
if (!$this->upload->do_upload($fieldname))
{
$errors[] = $this->upload->display_errors();
}
else
{
//success code
}
}
}
