Hi
can i manipulate the data that is being process on the server side?

for example lets say i have this field:

Field::inst( 'email' ) => this translate to : "jon@gmail.com" on the client side.

and i want something like this

Field::inst( 'email' )."test" => this translate to : "jon@gmail.comtest" on the client side.

I know i can do it with the js in client side, but it would be much better to resolve it on the server side (php).

Thanks

i got it

->getFormatter( function ( $val, $data, $opts ) {
return $val.'x' ;
})
