copied!<p>You never actually give access to the <code>PDO</code> instance <code>$dbh</code> to the things youre trying to use it in. It seems like youre using classes simple as groupings of functions but also expecting some magic to happen :-) This is how i would do it with your existingcode:</p> <pre><code>class DB_Class { protected $dsn; protected $user; protected $password; protected $connection; public function __construct($dsn = null, $user = null, $password = null) { $this->dsn = $dsn; $this->user = $user; $this->password = $password; } public function connect() { if($this->connection) { return $this->connection; } try { $this->connection = new PDO($this->dsn,$this->user, $this->password, array( PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8" )); $this->connection->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_WARNING); $this->connection->setAttribute(PDO::ATTR_CASE,PDO::CASE_LOWER); return $this->connection; } catch (PDOException $e) { return false; } } } class User { protected $db; public function __construct(DB_Class $db = null) { $this->db = $db; } public function setDb(DB_Class $db) { $this->db = $db; } public function get_fullname($uid) { $stmt = $this->db->connect()->prepare("SELECT EmailAddress FROM users WHERE UserID =:username"); $stmt->execute(array(':username', $uid)); if($row = $getName->fetch()) { return $row['emailaddress']; } else { return null; } } } </code></pre>
