Template Functionsvoid smarty_function_namearray $paramsobject &$smarty
All attributes passed to
template functions from the template are contained in the
$params as an associative array.
The output (return value) of the function will be substituted in place of
the function tag in the template, eg the
{fetch}
function. Alternatively, the function can simply perform some other
task without any output, eg the
{assign} function.
If the function needs to assign some variables to the template or use
some other Smarty-provided functionality, it can use the supplied
$smarty object to do so eg
$smarty->foo().
