？ 而不是通过zend update获得价值

Question

I'm trying to make updates querys with Zend_Db_Adapter but when I make an echo of the querys, the value that I want to update is still an "?". I check the value $foo, I always have 1 or 0 My code :

$this->_db->beginTransaction();
try {
    foreach($a_result as $k => $j){
        $foo = ($j['val1'] >= $j['val2']) ? 1 : 0 ;
        $a_data = array('bar' => $foo);
        $where['id = ?'] = $k;
        $update = $this->_db->update($this->_name, $a_data, $where);                                    
    }
    $this->_db->commit();
} catch (Exception $e) {
    $this->_db->rollBack();
    echo $e->getMessage();
}

All my querys looks like this :

• UPDATE foo SET bar = ? WHERE (id = 39)
• UPDATE foo SET bar = ? WHERE (id = 40)
• [...]

This code works for me, try to put it inside your loop and see if it helps :)

$a_data = array(
            'bar' => $foo
);

$_where = array();
$_where[] = "id = '" . $k . "'";

Besides that, I think your problem resides in the $where, it's written in a strange way. I usually use, for selects

->where('ID = ? ', $k)

In your case I would use

$where = $this->_yourTable->getAdapter()->quoteInto('id = ?', $id)

Anyway, the first one should be simpler!
