use this function instead:

$FoxFilterFunctions['nocomma'] = 'nocomma';
function nocomma($pagename, $fields) {
    $fields['pagename'] = preg_replace('/,/', ' ', $fields['pagename']);
return $fields;

you have to do that in the function. Fox will just run the filter
function, if it is specified as foxfilter in the form, regardless of
any field names. I.e it is generic, and not aimed at
processing (filtering) just a specific field.
