If i select file, have following error in case i have in <code>input:file</code> this: <code>name="userfile[]"</code>: <code>Message: Undefined index: userfile</code> in here:<code>print_r($_FILES['userfile']);</code> Update 2: I use from these Controller but if don't select a file, in the here <code>if ( ! $files )</code> return is false and give error. i want if user did not select file does not get error with a if <pre><code>class Upload extends Controller { function Upload() { parent::Controller(); $this->load->helper(array('form', 'url')); } function index() { $this->load->view('upload_form'); } function do_upload() { if($_FILE('userfile')){ $config['upload_path'] = './uploads/'; // server directory $config['allowed_types'] = 'gif|jpg|png'; // by extension, will check for whether it is an image $config['max_size'] = '1000'; // in kb $config['max_width'] = '1024'; $config['max_height'] = '768'; $this->load->library('upload', $config); $this->load->library('Multi_upload'); $files = $this->multi_upload->go_upload(); if ( ! $files ) { $error = array('error' => $this->upload->display_errors()); $this->load->view('upload_form', $error); } else { $data = array('upload_data' => $files); $this->load->view('upload_success', $data); } } redirect('inse/show'); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
