Загрузка CSV-файла не работает с Codeigniter

Я использую ниже код для загрузки файлов csv. Всегда ли он говорит о некорректном файле error.please, помогите мне исправить эти проблемы?

Вот моя форма:

• Неустранимая ошибка: вызов неопределенной функции pg_connect ()
• Проблема с heredoc и PHP
• PHP - переопределить существующую функцию
• Шаблон Twig не может содержать шаблон php
• Обработка загружаемых загрузок plupload на стороне сервера
• Могу ли я использовать MS SQL Server в качестве базы данных поддержки для Joomla?

<form name="bulk_dealer" action="<?= base_url() ?>admin/add_bulk_user" method="post" accept-charset="utf-8" enctype="multipart/form-data"> <ul> <ul> <li class="ui-field"><label for="csvfile">Upload dealer id file( *only .csv) :</label></li> <li class="ui-input"><input type="file" name="csvfile" value="" placeholder="" required=""></li> <li><input type="submit" value="Upload" name="Upload" class="ui-submit"></li> </ul> </ul> </form> 

вот мой контроллер

 function add_bulk_user() { $data['add_bulk_user_errors'] = NULL; $data['add_bulk_user_success'] = NULL; if ($this->input->post() !== FALSE) { $config_arr = array( 'upload_path' => './uploads/csv/', 'allowed_types' => 'text/plain|text/csv|csv', 'max_size' => '2048', 'max_width' => '1024', 'max_height' => '768', 'encrypt_name' => true, 'file_name' => 'dealer' ); $this->load->library('upload', $config_arr); if (!$this->upload->do_upload('csvfile')) { $data['add_bulk_user_errors'] = $this->upload->display_errors(); // this isn't working } else { $csvfilepath = "uploads/csv/" . $config_arr['file_name']; $this->addfromcsv($csvfilepath); $data['qs'] = $this->upload->data(); $row = 1; if (($handle = fopen("./uploads/csv/dealer.csv", "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $num = count($data); $row++; for ($c = 0; $c < $num; $c++) { $this->load->model("login_model"); $is_esist = $this->login_model->check_is_exist($data[$c]); if ($is_esist) { } else { $this->login_model->set_login($data[$c], 'dealer@ceat123'); } } } fclose($handle); } $data['add_bulk_user_success'] = "File Uploaded Successfully"; } $data['main_content'] = 'admin/add'; $this->load->view('admin_layout', $data); redirect('admin/add_bulk_user', 'refresh'); } else { $data['main_content'] = 'admin/add'; $this->load->view('admin_layout', $data); } }
