Editor 'preCreate ' event - php script variable not accesible in on 'preCreate ' function.

What wrong is with the code below:

$ev = -1;
if (isset($_SERVER['QUERY_STRING'])) {$ev = (int)$_SERVER['QUERY_STRING'];}
$editor = Editor::inst( $db, 'stands', 'id' )
    ->fields(
        Field::inst( 'company_name' )
            ->validator( 'Validate::notEmpty' ),
        Field::inst( 'stand_number' ),
        Field::inst( 'event_id' ) ->set( Field::SET_CREATE )
);
$editor ->on( 'preCreate', function ( $editor, $values ) {
       $editor
         ->field( 'event_id' )
         ->setValue( $ev );
} );
if($ev != -1) $editor   ->where( 'event_id', $ev);
$editor ->process( $_POST )
    ->json();

and - for some reasons - the $ev variable is accesible only for "where", but not in 'preCreate' function.
As a result it throws system error and Unknown variable notice for the $ev variable occurence in the on 'preCreate' function. Help, please.

Are you getting an error from that code, or in what way is it not doing want you expect?

for some reasons - the $ev variable is accesible only for "where", but not in 'preCreate' function.

That is how PHP closures work for some bonkers reason. You need to add use( $ev ) to the closure definition to be able to access the variable in the closure - see the PHP documentation.

Thanks. That really helped.

$editor ->on( 'preCreate', function ( $editor, $values )  use( $ev ){
