phpthumb 在开发机器 ubuntu 上工作，而不在服务器 ubuntu 上工作

Question

我在 http://support 中交叉发布.silisoftware.com/phpBB3/viewtopic.php?f=2&t=255&p=806 但如果有答案，我会更新双方的情况。

我使用 capistrano 部署到我的服务器。所以涉及到符号链接。

开发机和服务器都使用ubuntu 10.04，

代码完全相同，但开发机没有问题，而服务器有问题。

这是我的开发机器上的服务器调试消息的 php 包列表

Answer 1

解决方案是设置 phpthumb.class.php 第 142 行

var $config_allow_src_above_docroot = true;

这可能是由于 capistrano 使用符号链接，但不能确定。

Answer 2

您可以使用 setParameter 函数修复此问题：

$phpThumb->setParameter('config_allow_src_above_docroot', true);

Answer 3

我有同样的情况，我通过 codeigniter 中的“根路径”FCPATH 解决了
或者（define('FCPATH', dirname(__FILE__).'/'); 在您的index.php 文件中）
或者（define('FCPATH', __DIR__.'/'); 在您的index.php 文件中）
例如：define('FCPATH', 'C:/xampp/htdocs/your_project/');

$relative_path = 'images/upload/demo.jpg';
$phpThumb->RenderToFile(FCPATH .$relative_path);
