boolean

# Syntax

(*bool)
(*boolean)

# Examples

• (*bool)${USER.isAuthenticated} - returns true if user is authenticated
• (*boolean)${ENV.PRODUCTION_FLAG} - returns true if environment var PRODUCTION_FLAG contains a value that can be converted to true as mentioned below.

# Definition

Convert any value to a boolean true or false. When converting to boolean, the following values are considered as false:

• the boolean false itself
• the integer 0 (zero)
• the floats 0.0 and -0.0 (zero)
• the empty string "", and the string "0"
• an array with zero elements
• the unit type NULL (including unset variables)
• Internal objects that overload their casting behavior to bool. For example, SimpleXML objects are created from empty elements without attributes.

The following policy is designed for a multisite network setup. When there is a need to restrict access to other sites the user does not belong to, you can apply this policy.

If a user is not a member of a site, the access will be denied and handled as defined with the Access Denied Redirect rule (by default “Access Denied” message will be printed).
