following output in

 data =     {         userfile =         {             error = 0;             name = imgname;             size = 146245;             "tmp_name" = "/tmp/phppylh8a";             type = "image/jpeg";         };     };     message = "<p>you did not select file upload.</p>";     name = s;     type = i;

please me how can fix

you need use below code uploading data:

$config = array(             'upload_path' => $path,             'allowed_types' => 'jpg|gif|png|jpeg',             'overwrite' => 1,             );             $this->load->library('upload', $config);             $images = array();             foreach ($files['name'] $key => $image) {                 if ($image != '') {                     $_files['userfile[]']['name'] = $files['name'][$key];                     $_files['userfile[]']['type'] = $files['type'][$key];                     $_files['userfile[]']['tmp_name'] = $files['tmp_name'][$key];                     $_files['userfile[]']['error'] = $files['error'][$key];                     $_files['userfile[]']['size'] = $files['size'][$key];                     $image = str_replace(' ', '_', $image);                     $filename = time() . '_' . $image;                     $images[] = $filename;                     $config['file_name'] = $filename;                     $this->upload->initialize($config);                     if ($this->upload->do_upload('images[]')) {                         $this->upload->data();                     } else {                         return false;                     }                 }             }
