I have a upload file where you could could do is <input type="file=" name="categoryIcon[]" multiple="multiple"/> and should pick it up you can change do_upload what ever you want.
Also change
This $config['upload_path'] = dirname($_SERVER["SCRIPT_FILENAME"])."/assets/images/categories/";
To This $config['upload_path'] = "./assets/images/categories/"; If your upload folder in on main directory you do not need dirname refer user guide http://www.codeigniter.com/user_guide/libraries/file_uploading.html
echo file data
'$file_info = $this->upload->data();'
'echo $file_info['file_name'];'
Just a example works for multiple codeigniter uploads.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Upload extends CI_Controller {
function index()
{
$this->get_list();
}
public function get_list() {
$this->load->view('upload_success');
}
function do_upload() {
$this->load->library('form_validation');
// You need to set a form set rules
//$this->form_validation->set_rules('name', 'Banner Name', 'required');
if ($this->form_validation->run()) {
$files = $_FILES;
$file_loop = count($_FILES['categoryIcon']['name']);
for($i= 0; $i < $file_loop; $i++) {
$_FILES['categoryIcon']['name'] = $files['categoryIcon']['name'][$i];
$_FILES['categoryIcon']['type'] = $files['categoryIcon']['type'][$i];
$_FILES['categoryIcon']['tmp_name'] = $files['categoryIcon']['tmp_name'][$i];
$_FILES['categoryIcon']['error'] = $files['categoryIcon']['error'][$i];
$_FILES['categoryIcon']['size'] = $files['categoryIcon']['size'][$i];
$this->upload->initialize($this->file_config());
if (!$this->upload->do_upload()) {
$this->get_form();
} else {
$filename = $files['categoryIcon']['name'][$i];
$this->get_list();
}
} else {
$this->get_form();
}
}
public function get_form() {
$data['error'] = $this->upload->display_errors('<div class="alert alert-info">', '</div>');
$this->load->view('upload_form', $data);
}
private function file_config() {
$config = array();
$config['upload_path'] = './upload/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '0';
$config['overwrite'] = TRUE;
return $config;
}
}
