you store error in $files_uploaded[$i] = $this->upload->display_errors(); not use of display error need fetch error array , display on view.
please see below code.
<?php class upload extends ci_controller { function __construct() { parent::__construct(); $this->load->helper(array('form', 'url')); } function index() { $this->load->view('upload_form', array('error' => ' ' )); } function do_upload() { $config['upload_path'] = './uploads/'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '100'; $config['max_width'] = '1024'; $config['max_height'] = '768'; $this->load->library('upload', $config); if ( ! $this->upload->do_upload()) { $error = array('error' => $this->upload->display_errors()); $this->load->view('upload_form', $error); } else { $data = array('upload_data' => $this->upload->data()); $this->load->view('upload_success', $data); } } } ?>
