[fw-general] Zend_Validate_Alnum::isValid evaluating alnum strings as false

[Graham Anderson]

I updated against trunk and now...

require_once('Zend/Validate/Alnum.php');

$validator = new Zend_Validate_Alnum();

$vars = array ( 'Alnum' => 'foobar1',
                                'NotAlnum' => '[EMAIL PROTECTED]' );

foreach ( $vars as $var ) {
        echo $validator->isValid($var) ? $var .':true ' : $var . ':false ';
}

--
result: foobar1:false [EMAIL PROTECTED]:false
