Modifiers
Modifiers are little functions
that are applied to a variable in the template before it is displayed or
used in some other context. Modifiers can be chained together.
mixed smarty_modifier_namemixed $value[mixed $param1, ...]
The first parameter to the modifier plugin is the value on which
the modifier is to operate. The rest of the parameters are optional,
depending on what kind of operation is to be performed.
The modifier has to return
the result of its processing.
