lots of warnings with debian 8.11 and php 7.2

[Ramstin13]

Current PHP version: 7.2.16-1+020190307202206.17+jessie1.gbpa7be82
Debian GNU/Linux 8.11 (jessie)

when i enter the gui i get:

Notice: Undefined index: id in /var/www/vnstat/includes/vnstat.php on line 81

[Ramstin13]

i think that having only one interface is the problem, because in vnstat.php on line 81 i see this

public function getInterfaces() {
// Create a placeholder array
$vnstatInterfaces = [];

            foreach($this->vnstatData['interfaces'] as $interface) {
                    array_push($vnstatInterfaces, $interface['id']);
            }

            return $vnstatInterfaces;
    }

and i only have the lo and eth0 interface on the vm i am trying this gui.

[tomangert]

I don't think this branch works well with vnstat 2.x yet.

I have a version here that works for me:
https://github.com/tomangert/vnstat-dashboard

Feel free to try it

Feel free to try it

yeah, with your branch i get no errors.
i think it is because of vnstatjsonversion, using interface['id'] and not interface['name']

thank you tomangert

[qwrty-ftw]

Yes, thank you @tomangert !

Your version fix my issue:
#40 (comment)

But I have no more graphical stats by the way.
