Call to undefined function tmpfile()

[claytonk]

I'm running AjaxUpload in a FormitForm and am getting a fatal PHP error from fileuploader.class.php. The error doesn't make sense. It's failing to find the PHP tmefile() function. Here's the redacted error output:

PHP Fatal error:  Uncaught Error: Call to undefined function tmpfile() in /---/public_html/core/components/ajaxupload/model/fileuploader/fileuploader.class.php:38

Any idea what might be causing this? Any advice would be welcome.

This error message does not make sense, tmpfile is a core PHP method. Is it possible that this method is disabled on your hosting? https://www.php.net/manual/en/ini.core.php#ini.disable-functions

Yeah, that's what I'd thought as well but couldn't locate the issue in our setup. Talked with the host, discovered the issue, all good. Thanks for the reply.
