void register_function ( string name, mixed impl, bool cacheable, mixed cache_attrs)
Use this to dynamically register template function plugins.
Pass in the template function name, followed by the PHP
function name that implements it.
The php-function callback impl can be either (a) a string
containing the function name or (b) an array of the form
array(&$object, $method) with
&$object being a reference to an
object and $method being a string
containing the mehod-name or (c) an array of the form
array(&$class, $method) with
$class being a classname and
$method being a class method of that
class.
cacheable and cache_attrs can be
omitted in most cases. See Controlling Cacheability of Plugins' Output
on how to use them properly.
Example 1. register_function
<?php
$smarty->register_function("date_now", "print_current_date");
function print_current_date($params)
{
if(empty($params['format'])) {
$format = "%b %e, %Y";
} else {
$format = $params['format'];
return strftime($format,time());
}
}
// now you can use this in Smarty to print the current date: {date_now}
// or, {date_now format="%Y/%m/%d"} to format it.
?>
