[Ramstin13]

Current PHP version: 7.2.16-1+0~20190307202206.17+jessie~1.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 Notice: Undefined index: id in /var/www/vnstat/includes/vnstat.php on line 81 Notice: Undefined variable: typeAppend in /var/www/vnstat/includes/vnstat.php on line 118 Notice: Undefined variable: i in /var/www/vnstat/includes/vnstat.php on line 120 Warning: Use of undefined constant sortingFunction - assumed 'sortingFunction' (this will throw an Error in a future version of PHP) in /var/www/vnstat/includes/vnstat.php on line 136 Notice: Undefined variable: typeAppend in /var/www/vnstat/includes/vnstat.php on line 160 Notice: Undefined variable: i in /var/www/vnstat/includes/vnstat.php on line 162 Notice: Undefined variable: typeAppend in /var/www/vnstat/includes/vnstat.php on line 186 Notice: Undefined variable: i in /var/www/vnstat/includes/vnstat.php on line 188 Notice: Undefined variable: typeAppend in /var/www/vnstat/includes/vnstat.php on line 102 Notice: Undefined variable: i in /var/www/vnstat/includes/vnstat.php on line 104 Notice: Undefined variable: typeAppend in /var/www/vnstat/includes/vnstat.php on line 139 Notice: Undefined variable: i in /var/www/vnstat/includes/vnstat.php on line 141 Notice: Undefined variable: typeAppend in /var/www/vnstat/includes/vnstat.php on line 171 Notice: Undefined variable: i in /var/www/vnstat/includes/vnstat.php on line 173 Notice: Undefined variable: typeAppend in /var/www/vnstat/includes/vnstat.php on line 197 Notice: Undefined variable: i in /var/www/vnstat/includes/vnstat.php on line 199

and then, te graphic appears... screenshot below

[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.

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: https://github.com/alexandermarston/vnstat-dashboard/issues/40#issuecomment-627148032

But I have no more graphical stats by the way.
