Permissions

What are Permissions ?

permission is a boolean expression (TRUE/FALSE) that determine who/when could view/edit/update…etc a piece of content or a section.

h2.What are the permissions tokens ?

you can use 2 types of tokens :

1. Connector : and, or, not
2. Operator : =, !=, >, <, >=, <=, !
3. Boolean variables : (True/false) variable like ,admin, logged, guest, view, edit
4. Numeric variables : group, user, section, day, month, year
   the permission syntax is :

expression Connector expression
expression = expression Connector expression 
expression = {BooleanVariable} or {NumericVar Oper Number}

example :

guest or user=4 and day=13

that will be true if the user guest in or user ID equal to 4 and the current day is 13,
if you want to exclude user 14 from the permission.

guest or !user=4 and day=13

that will show for guest user or not the user 4 and day is 13

some other examples :

logged

admin or group=5

!group=6 and user=5 and user=7

group=3 and day>1 and day<10 and year>=2011
