Two prepared statements on one page - first works, second fails - mysql

Question

I'm using MDB2 for prepared statements. I'm using the name-based example from the PEAR MDB2 site as a guide, and this is what I have so far:
$q = '
UPDATE
abc_news
SET
newstitle = :newstitle,
categoryid = :categoryid,
facilityid = :facilityid,
user_id_mod = :user_id_mod,
user_id_add = :user_id_add,
display = :display,
locked = :locked,
datemodified = NOW()
WHERE
newsid = :newsid
';
$types = array(
'text',
'integer',
'integer',
'integer',
'integer',
'integer',
'integer',
'integer',
);
$res = $mdb2_dbx->prepare($q, $types,MDB2_PREPARE_MANIP);
$data = array(
'newstitle' => $n_newstitle,
'categoryid' => $n_categoryid,
'facilityid' => $n_facilityid,
'display' => 1,
'locked' => 1,
'user_id_add' => $n_user_id_add,
'user_id_mod' => $n_user_id_mod,
'newsid' => $newsid,
);
$affected_rows = $statment->execute($data);
if (PEAR::isError($res))
die('error');
$statement->free();
$q = '
UPDATE
abc_news_text
SET
newstext = :newstext
WHERE
newsid = :newsid
';
$types = array(
'text',
'integer',
);
$statment = $mdb2_dbx->prepare($q, $types,MDB2_PREPARE_MANIP);
$data = array(
'newstext' => $n_newstext,
'newsid' => $newsid,
);
$affected_rows = $statment->execute($data);
if (PEAR::isError($res))
die('error');
$statement->free();
The first query works - an autoincremented $newsid is printed to the screen (it increases with each new submission).
Directly below, I get this error:
Fatal error: Call to undefined method MDB2_Error::execute() in news.php on line 160
Line 160 is the second $affected_rows = $statment->execute($data); line.
I'm freeing up the statement, and the syntax appears to be the same on both prepared statements.
What am I doing wrong here?

Answer 1

that is because You are getting an MDB2_ERROR object not a statement object. Your prepare() obviously didn't work and you are not checking for the success of the prepare() at all to know this.
Also, I am not sure how your first is working since you set the prepare result to $res variable instead of $statment. I also notice your variable name $statment has no e (not sure if this was a typo).
