drupal - 如何将文件上传到drupal模块中的文件夹位置？

Question

如何以 drupal 模块方式将文件上传到文件夹位置... 我正在创建一个模块(示例)，因为我想创建一个上传文件，以便将其存储在特定位置(文件夹)中。不使用 cck 请帮助我...我是这样编码的

$form['pem_file_upload'] ['certificates'] = array (
  '#type' => 'file',
  '#value' => 'upload',
  '#title' => t('upload your certificate file'),
  '#description' => t('Upload the certificate file which is helpfull in sending push messages to ios device'),
  '#default_value' => variable_get('certificates', ''),
);

variable_set('certificates', $form_state['values'] ['certificates']);

$form['pem_file_upload'] ['certificates'] = array (
  '#type' => 'file',
  '#value' => 'upload',
  '#title' => t('upload your certificate file'),
  '#description' => t('Upload the certificate file which is helpfull in sending push messages to ios device'),
  '#default_value' => variable_get('certificates', ''),
);

variable_set('certificates', $form_state['values']['certificates']);

为了保存文件本身，这是您需要的功能

$file = file_save_upload('pem_file_upload', array(), 'public://yourfolder' . variable_get('document_path', ''), FILE_EXISTS_RENAME);

    if ($file) {
        //Set the status of the uploaded file.
        $file->status = FILE_STATUS_PERMANENT;
        file_save($file);
}

public://是一种流格式，指向sites/all/default/files有关更多信息，请参阅 drupal 7 file api
