Call to undefined method PDO::bindParam()

Question

Can someone tell me why I am getting this error? Call to undefined method PDO::bindParam()

Here is what I have, taken right off of PHPs site for stored procedures

Answer 1

The bindParam() function is a method of a PDOStatement object, not a PDO object. $stmt is an object of class PDO. You'll have to use the PDOStatement from your prepare() call instead.

$pdo = db::getInstance();
$stmt = $pdo->prepare("your query");
$stmt->bindParam(2122, $return_value, PDO::PARAM_STR, 4000);
