I've been working with the Zend Framework a bit and in working with MySQL through PDO_MYSQL. I've run into a few problems trying to use parameters of queries.
I've narrowed the issue down to PDO itself and not the Zend Framework.
$dbh = new PDO("mysql:host=localhost;dbname=db","user","pw");
$query = "insert into silo_test_data (record_id, fieldname, value)
values (3,'stufftest', :value )";
$handle = $dbh->prepare($query);
$handle->execute(array(":value" => 'crap'));
$dbh = null;
The value gets inserted into the database as an empty string, or sometimes some low-value bytes. I've managed to work around this temporarily thanks to some help from this post. By setting PDO to emulate prepared statements, everything seems to work okay.
The problem is, the Zend framework encapsulates the actual db connection and connects lazily. So, for now I'm running a query and then set the parameter on the encapsulated connection object.
$db_connect = array( 'host' => $config->db->hostname,
'username' => $config->db->username,
'password' => $config->db->password,
'dbname' => $config->db->database );
$db = Zend_Db::factory('PDO_MYSQL', $db_connect);
$db->query('select 1');//HACK HACK HACK HACK to initiate connection. Can't I make this a plugin? or extend the class?
