CodeIgniter: недопустимый тип файла, который вы пытаетесь загрузить.isset ($ this -> _ mimes [$ ext]) всегда равно нулю

Question

Я потратил часы на эту проблему, но понятия не имею, как ее исправить.У меня появляется сообщение об ошибке при попытке загрузить изображение.Сообщение об ошибке: «Тип файла, который вы пытаетесь загрузить, запрещен».Но я не думаю, что тип файла вызывает эту проблему.Я узнал, что ! $this->upload->do_upload('image') всегда ложно.и я узнал, что это потому, что $this->_mimes[$ext]) (который находится в файле "system / library / Upload.php".) всегда приносит мне NULL.

Когда я проверял свою функцию, я пытался var_dump($this->file_type);и получил "image / jpeg".

Я также попытался var_dump($ext); и получил "jpg".

Это часть файла Image.php.

<?php echo form_open_multipart('/image/index');?>
  <fieldset>
    <legend>Upload Image</legend>
    <div><label>File: </label><input id="image" type="file" name="image" /></div>
    <div><label>Title: </label><input id="title" type="text" name="title" /></div>
    <div class="error">
      <?php echo $error; ?>
    </div>
  </fieldset>

  <div class="form_line"><input id="image_submit" type="submit" value="Upload Picture" class="submit" /></div>
</form>

Это часть файла Picture.php.

function index()
{
  $config['upload_path']          ='./uploads/';
  $config['allowed_types']        = 'gif|jpg|png|jpeg';
  $config['max_size']             = 40960000;
  $config['max_width']            = 0;
  $config['max_height']           = 0;

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

  if ( ! $this->upload->do_upload('image'))
    {
      $page_data = array('files' => $file_send, 'error' => $this->upload->display_errors());
      $this->load->view('media/image_upload', $page_data);
    }
  else {...}
}

Здесь я нашел нулевое значение.Это код CodeIgniter.

public function is_allowed_filetype($ignore_mime = FALSE)
{
    if ($this->allowed_types === '*')
    {
        return TRUE;
    }

    if (empty($this->allowed_types) OR ! is_array($this->allowed_types))
    {
        $this->set_error('upload_no_file_types', 'debug');
        return FALSE;
    }

    $ext = strtolower(ltrim($this->file_ext, '.'));

    if ( ! in_array($ext, $this->allowed_types, TRUE))
    {
        return FALSE;
    }

    // Images get some additional checks
    if (in_array($ext, array('gif', 'jpg', 'jpeg', 'jpe', 'png'), TRUE) && @getimagesize($this->file_temp) === FALSE)
    {
        return FALSE;
    }

    if ($ignore_mime === TRUE)
    {
        return TRUE;
    }

    // isset($this->_mimes[$ext]) is always null
    if (isset($this->_mimes[$ext]))
    {
        return is_array($this->_mimes[$ext])
            ? in_array($this->file_type, $this->_mimes[$ext], TRUE)
            : ($this->_mimes[$ext] === $this->file_type);
    }

    return FALSE;
}

Если у вас есть предложения по этой проблеме, я буду очень признателен.

Извините, если что-то не понятно.Если вам нужно больше кодов, я предоставлю их наверняка.

Answer 1

Я понял это.Это было из-за файла mimes.php .Ранее CodeIgniter предоставлял mimes.php с этим форматом.$mimes = array( 'hqx' => 'application/mac-binhex40',....Однако текущий CodeIgniter изменил формат на return array( 'hqx' => array('application/mac-binhex40', ....Когда я обновил фреймворк, я не обновил файл mimes.php .Большое спасибо, Алекс, за подсказку!

Вот измененный mimes.php .
