Hi André and happy Friday!
I think that depends on how the event price is being imported to The Events Calendar. For example, if the price range of the imported event is imported as the cost field for the event, then you could use both the tribe_get_minimum_cost() and tribe_get_maximum_cost() functions to display the range in a way like this:
<?php echo tribe_get_minimum_cost() . ' - ' tribe_get_maximum_cost(); ?>
Depending on the configuration, you might need to wrap that line of code in a conditional statement that checks whether the event has tickets or not before displaying that range, and we have the tribe_events_has_tickets() function for that.
Does this make sense and will it help you get started? Please let me know. 🙂
Cheers,
Geoff
