You have two things wrong .. Your HEADER needs to be located at the top of the file to prevent "Headers already sent" error. -- Plus it's always a good idea to throw a DIE in afterward for good measure.
Second, you need to put your POST query in quotes as it is a string you are looking for.
Plus as Fred mentioned in comments, you have a stray FORM tag
<?php
if ( !empty($_POST['parola']) && $_POST['parola'] == 'google') {
header("Location: http://google.com");
die();
}
?>
