Upload multiple images in Codeigniter

First of all, you must create a table images in your database

Follow  the following code in your controllers

$this->load->library('upload');

    foreach ($_FILES['picture']['name'] as $key => $value) {

      $secure_id = get_secure_id($id).rand(1, 100);

      $_FILES['picture_'.$key]['name'] = $_FILES['picture']['name'][$key];

      $_FILES['picture_'.$key]['type'] = $_FILES['picture']['type'][$key];

      $_FILES['picture_'.$key]['tmp_name'] = $_FILES['picture']['tmp_name'][$key];

      $_FILES['picture_'.$key]['error'] = $_FILES['picture']['error'][$key];

      $_FILES['picture_'.$key]['size'] = $_FILES['picture']['size'][$key];

  if (!empty($_FILES['picture']['tmp_name'][$key]))

  {

        // set upload directory. create if not exist

        $org_directory = PATH_IMAGE.$this->session->vendor_id;

        if (!file_exists($org_directory)) {

          mkdir($org_directory, 0755, true);

        }

        // 1. upload file

        $file_name = $org_directory.$secure_id.'.jpg';

        // if file exist, delete

if (file_exists($file_name)) {

unlink($file_name);

}

        $config['upload_path'] = $org_directory;

$config['allowed_types'] = 'gif|jpg|png|jpeg';

$config['file_name'] = $secure_id.'.jpg';

$this->upload->initialize($config);

//do upload

if ($this->upload->do_upload('picture_'.$key))

{

$image_data = $this->upload->data();

          // image manipulation

$config2['image_library'] = 'gd2';

$config2['source_image']  = PATH_IMAGE.$this->session->vendor_id.'/'

.$image_data['raw_name'].'.jpg';

$config2['maintain_ratio'] = TRUE;

$config2['width'] = 800;

$this->load->library('image_lib', $config2);

          $this->image_lib->resize();

          $this->image_lib->clear();

$fields['image'] = $this->session->vendor_id.'/'.$image_data['raw_name'].

'.jpg';

  }

else

{

$fields['image'] = NULL;

        }

        

          $data_array = array(

            'invoice_id' => $id,

            'image' => $fields['image'],

          );

          $this->db->insert('images', $data_array);

      }

}

Make a looping as above so that you can upload multiple images.
