This is working:
{if $filter.id_key='68'}
This doesn't:
{if ($filter.id_key='68' || $filter.id_key='63')}
Not sure what's wrong here (tried also without the round brackets). There are plenty of examples of the same OR statement in the same file.
In {if $filter.id_key='68'}
you are assigning 68
to $filter.id_key
, so it's always true. You should use double equal ==
:
{if ($filter.id_key == '68' || $filter.id_key == '63')}
