Call to undefined function DataTables\Editor\finfo_open()

aarontharker

When trying to get the mime types for file uploads working I am getting this message. I am running php 5.6 so any idea what maybe causing this?

allan

In the php/Editor/Upload.php file you will be able to find:

$finfo = finfo_open(FILEINFO_MIME);

Changing that to be:

$finfo = \finfo_open(FILEINFO_MIME);

I think should resolve it.

Could you give me the full version string for your PHP install please? I'd expected this to be a very early 5.3 release from the error message you are seeing. I'm really surprised to see it in 5.6.

The error message I'm getting is

<br />
<b>Fatal error</b>:  Uncaught Error: Call to undefined function finfo_open() in /php/lib/Editor/Upload.php:603

I added the preceding backslash as you suggested and it hasn't changed anything. This is running on PHP 7.1.

I replaced the function in that file with mime_content_type() and that doesn't work either! That function is also not found on my PHP server, for whatever reason.

I created an independent file with only
````
<?php
echo mime_content_type("info.php");

<?php > ```` And this has a fatal error, indicating that the necessary functions don't exist on my server's installation of PHP. ?>

It turns out that Dreamhost doesn't include the correct extension by default, so I needed to add extension=fileinfo.so to my php.ini file.

It sounds like the Dreamhost PHP might be a bit limited. mime_content_info is a core part of PHP. It might be worth asking Dreamhost about that.
