Problem using mdb2 execute()

[ralf]

My code:

$mdb2 =& MDB2::connect($dsn);
if (PEAR::isError($mdb2)) {
die($mdb2->getMessage());
}

$data = array('now()', 'title1', 'content1');
$types = array('Timestamp', 'text', 'text');

$sth = $mdb2->prepare('INSERT INTO tb1 (time_t, string_t, text_t) VALUES (?, ?, ?)', $types, MDB2_PREPARE_MANIP);

$affectedRows = $sth->execute($data);

echo "ok!";

I get the following problem:
print ok! ,but the table tb1 has nothing. the data didn't inserted

BTW:I have already install mdb2_driver_mysql and run code well like

$res =& $mdb2->query('SELECT * FROM tb2');
$row = $res->fetchOne(1,0);

did you ever figure this out?

I am trying to use mdb2 and selects work fine, but any insert is throwing an:

'unable to find package 'MDB2_Datatype' error.

any suggestions?

thanks.
