When echo multiple file data it only display last file info - codeigniter

Question

On my multiple upload library I have a function which is called upload data.
And another function called upload.
For some reason when I select multiple images and is success full when I use on my controller
$data = $this->multiple_upload->upload_data();
echo $data['file_name'];
It will only get the name of the last file selected it does not return all file names selected. It should display all file names selected.
Question: How on my library function upload_data() can I make sure can return data correctly rather than just the last one. the upload_data function just seems to only return the last file information.
Library
<?php
class Multiple_upload {
public function __construct($config = array()) {
$this->CI =& get_instance();
$this->files = $this->clean($_FILES);
empty($config) OR $this->set_config($config);
}
public function set_config($config) {

$this->$key = $value;
}
return $this;
}
public function upload($field = 'userfile') {
if (empty($this->upload_path)) {
$this->set_error('upload_path_not_set');
return FALSE;
}
if (!realpath(FCPATH . $this->upload_path)) {
$this->set_error('upload_path_in_correct');

}

$check_error++;
}
if ($this->files[$field]['size'][$key] > $this->max_size) {
$this->set_error('file_size_check');
$check_error++;
}
if ( ! #copy($this->file_temp, FCPATH . $this->upload_path . '/' . $this->file_name)) {
if ( ! #move_uploaded_file($this->file_temp, FCPATH . $this->upload_path . '/' . $this->file_name)) {

$check_error++;
}
}
}
if($check_error > 0 ) {
return FALSE;
}
// This lets me get file data in another function
return $this;
}
}
public function upload_data() {
$data = array(
'file_name' => $this->file_name,
'file_path' => FCPATH . $this->upload_path . '/'
);
return $data;
}
public function set_error($message) {
$this->CI->lang->load('upload', 'english');
$msg = "";
if ($message == 'upload_path_not_set') {
$msg .= $this->CI->lang->line($message);
}
if ($message == 'upload_path_in_correct') {
$msg .= $this->CI->lang->line($message);
}
if ($message == 'file_extension_not_allowed') {

}
if ($message == 'file_size_check') {
$msg .= sprintf($this->CI->lang->line($message), $this->file_name, $this->max_size);
}
return $this->error_message[] = $msg;

public function display_error_messages($open_tag = '<p>', $close_tag = '</p>') {
$message = "";
if (isset($this->error_message)) {
foreach($this->error_message as $msg) {

return $message;
}
public function clean($data) {
if (is_array($data)) {

$data[$this->clean($key)] = $this->clean($value);
}
} else {
$data = htmlspecialchars($data, ENT_COMPAT, 'UTF-8');
}
return $data;
}
}
I have tried
public function upload_data() {
$data[] = array(
'file_name' => $this->file_name,
'file_path' => FCPATH . $this->upload_path . '/'
);
return $data;
}
Controller index function
public function index(){
$data['error'] = '';
$this->load->library('multiple_upload');
$config['upload_path'] = 'uploads';
$config['allowed_types'] = array('jpg', 'png');
$config['max_size'] = 3000000;
//$config['max_size'] = 1000;
$config['overwrite'] = TRUE;
$this->multiple_upload->set_config($config);
if ($this->multiple_upload->upload() == FALSE) {
$data['error'] = $this->multiple_upload->display_error_messages('<div class="alert alert-danger">', '</div>');
$this->load->view('upload', $data);
} else {
$data = $this->multiple_upload->upload_data();
echo $data['file_name'];
}
}

Answer 2

you can use array to save all files information in upload_data function.
public function upload_data() {
$data = array(
'file_name' => $this->file_name,
'file_path' => FCPATH . $this->upload_path . '/'
);
return $data;
}
to
public function upload_data() {
$data[] = array(
'file_name' => $this->file_name,
'file_path' => FCPATH . $this->upload_path . '/'
);
return $data;
}
it will return array of all the file details
