Modifiers
Smarty provides modifiers that can be used to gain greater control over the formatting of data. Modifiers can be
included by following a variable with a vertical bar | and the name of the modifier. Any arguments to the modifier
can be specified using a colon : followed by the arguments.
The following example prints a date using the YYYY-MM-DD syntax:
{$expire_time|nwadateformat:"%Y-%m-%d"}
See"Date/Time Format Syntax" on page 279 for detailed information on the date/time format modifiers, and see
Table 26.

Predefined Template Functions
Template functions are used to perform different kinds of processing when the template is used. The result of a
template function takes the place of the function in the output of the template.
Functions are of two kinds: block functions , which have a beginning and ending tag enclosing the text operated on by
the function, and template functions , which have just a single tag and do not enclose text.
To use a function, enclose the function name in curly braces { } and provide any attributes that may be required for
the function. Block functions also require a closing tag.
