Hello All,

The Data::FormValidator docs say:
==== 


field_filters

 field_filters => { 
     cc_no => ['digit'],
 },

[download]
A hash ref with field names as keys. Values are array references of built-in filters to apply (trim,digit,etc) or an anonymous subroutine which should take one parameter, the field value and return the (possibly) modified value.

=====

OK so far, I want to use the mentioned anonymous sub. I'm not sure on the syntax. (How do I specify the input to pass in?) I set up a working sub MyFilter that takes one param. I tried: 

 field_filters => { 
     name_field => [ \MyFilter() ],
 },

[download]
That doesn't work, which doesn't surprize me as I don't see how MyFilter is getting its input.

Your comments and a working example would be much appreciated.

UPDATE: minor edit for a more illustrative field name
UPDATE 2: Working example from [monk://Tanktalus] : 

 field_filters => { 
     name_field => [ \&MyFilter ],
 },

Cheers
