Hi Besi,
it is not possible to use an interval different than the pre-installed ones. Anyhow, thanks to the overrides tool provided by VikRestaurants, you are able to easily (and safely) edit the code in order to accomplish this requirement.
Please, try to follow all the steps below:
- visit the Configuration page of VikRestaurants;
- access the Applications tab;
- click the Open Overrides Manager button;
- select Admin Pages from the dropdown located on the top-left side of the page;
- click the editconfig folder;
- open the default_restaurant.php file.
At this point you should edit the code at line 79:
foreach (array(10, 15, 30, 60) as $min)
into this one:
foreach (array(10, 15, 30, 60, 120) as $min)
After saving the changes, you should now be able to properly select “120” from the Minutes Interval setting.
