我在最近维护的一个网站上，这个功能已经停止工作了，我不知道确切的原因。第一个media\\u handle\\u upload功能失败，出现以下错误：

Array([error] => Specified file failed upload test.

尝试使用此代码而不是media\\u handle\\u upload，https://gist.github.com/hissy/7352933 , 但在使用gist中的代码时，我发现了一个错误：

017/05/17 05:45:59 [error] 2066#2066: *10499 FastCGI sent in stderr: "PHP message: PHP Warning:  file_get_contents(/tmp/php8mjcrC): failed to open stream: No such file or directory in /srv/www/test.dev/current/web/app/themes/test/functions.php on line 1083

这是我的功能。它连接到一个重力表单表单，该表单接受用户提交的照片。我想在媒体库中自动填充这些内容。它过去很管用，我不知道是什么破坏了它，可能是WordPress v4中的某些东西。7.

非常感谢您在这方面的帮助或指导。如果需要，我也可以提供更清晰的信息或代码。谢谢
