Do you mean {$foo|bar:p1:p2} ? You need to pass as many parameters to
your modifier as you have non-default parameters in your modifier's
function signature. Parameters are passed to the modifier function in
the order they are given in the template.

One thing to do is to implement your modifier as a method of your
(extended) Smarty class. Then manually register the modifier in the
constructor. That way the modifier has access to the current instance
of Smarty using $this. 

Trivial Example:

class MySmarty extends Smarty {

function MySmarty()
{
    $this->Smarty();
    $this->register_modifier('getvar', array('MySmarty',
'modifier_getvar'));
}

function modifier_getvar($bar, $baz=null)
{
    return $this->_tpl_vars($bar);
}

}

----

{assign var=test value=bar}
{"test"|getvar} {* results in 'bar' *}
