A few days ago, i installed daloradius. As a last step, i tried to transfer the heartbeat-data by calling dalo-dashboard-update-openwrt.sh from time to time.
dalo-dashboard-update-openwrt.sh
In the file dalo-dashboard-update-openwrt.sh there is a line saying
# Do not edit past this point
In fact i had to edit, because my wan-device is not eth0.2, but simply wan.
So maybe it would be better to have a section with:
WAN_DEV=
LAN_DEV=
WLAN_DEV=
and then work with
... wan_ip=ifconfig $WAN_DEV | awk '/inet addr/{print substr ($2,6)}' ...
The variable firmware_revision is missing, so i added
firmware_revision=cat /etc/os-release | awk '/OPENWRT_RELEASE/{print}' | sed "s/\"//g;s/ /%20/g;s/OPENWRT_RELEASE=//"
Replacing " and spaces is neccessary to not get error 400.
On the server side i had to edit heartbeat.php and db_open.php.
db_open.php: with my php8.1 if not checked isset($_SESSION) before array_key_exists('location_name', $_SESSION), the function exits.
[Tue May 02 11:33:50.239350 2023] [php:error] [pid 1822951] [client 192.168.64.203:33148] PHP Fatal error: Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array, null given in /var/www/html/daloradius/app/common/includes/db_open.php:39\nStack trace:\n#0 /var/www/html/daloradius/app/operators/heartbeat.php(67): require_once()\n#1 {main}\n thrown in /var/www/html/daloradius/app/common/includes/db_open.php on line 39
So change to
$location = (isset($_SESSION) &&
array_key_exists('location_name', $_SESSION) &&
isset($_SESSION['location_name']) &&
$_SESSION['location_name'] != "default")
? $configValues['CONFIG_LOCATIONS'][$_SESSION['location_name']]
: "";
heartbeat.php There are errors [Mon May 01 17:15:36.408716 2023] [php:error] [pid 1572012] [client 192.168.64.217:57020] PHP Parse error: syntax error, unexpected token ";" in /var/www/html/daloradius/app/operators/heartbeat.php on line 29
The lines
$wan_iface = (array_key_exists('wan_iface', $_GET) && !empty(trim($_GET['wan_iface'])) ? trim($_GET['wan_iface']) : "";
...
$cpu = (array_key_exists('cpu', $_GET) && !empty(trim($_GET['cpu'])) ? trim($_GET['cpu']) : "";
are all missing a ) at the and, so change to
$wan_iface = (array_key_exists('wan_iface', $_GET) && !empty(trim($_GET['wan_iface'])) ? trim($_GET['wan_iface']) : "");
...
$cpu = (array_key_exists('cpu', $_GET) && !empty(trim($_GET['cpu'])) ? trim($_GET['cpu']) : "");
Seems that php8.1 complains a bit more about errors than previous versions. Many thanks for your work Lutz

Yes you are right Thank you for your contribution i will check your code and update dalo-dashboard-update-openwrt.sh

Also i found out another bug in rep-hb-dashboard.php Line 175
. sprintf($format, t('all','WanGateway'), $row['wan_ip']);
Should be
. sprintf($format, t('all','WanGateway'), $row['wan_gateway']);
