Vtiger Tips and Tricks – Document Upload Issues

We recently had a client who was having trouble uploading documents into Vtiger. As we researched it, we determined it was a Vtiger bug of sorts.  We were surprised that we haven’t heard about this from more clients since it should impact all Vtiger 6.4 builds on PHP >= 5.3. Our developers were able to create workaround code to fix this issue for the client.

The issue was that Vtiger uses a function that has been deprecated in recent PHP versions, ‘mime_content_type’. This has been replaced with a php extension called ‘fileinfo’ in php versions >= 5.3

If you encounter this issue, here’s a way to get around it:

Enable the fileinfo php extension (debian/ubuntu):

$ apt-get install php5-fileinfo

And/or

$ php5enmod fileinfo

Modify index.php, add this at the bottom:

function _mime_content_type($filename) {
   $result = new finfo();

   if (is_resource($result) === true) {
       return $result->file($filename, FILEINFO_MIME_TYPE);
   }

   return false;
}
