PHP PDOException: "SQLSTATE[HY093]: Invalid parameter number"

mysql, pdo, php

Solution

Try:

$sql = "INSERT INTO persist (user_id, hash, expire)
        VALUES (:user_id, :hash, :expire)
        ON DUPLICATE KEY UPDATE hash=:hash2";

and

$stm->execute(
    array(":user_id" => $user_id, 
          ":hash" => $hash, 
          ":expire" => $future,
          ":hash2" => $hash)
);

Excerpt from the documentation (http://php.net/manual/en/pdo.prepare.php):

You must include a unique parameter marker for each value you wish to pass in to the statement when you call PDOStatement::execute(). You cannot use a named parameter marker of the same name twice in a prepared statement. You cannot bind multiple values to a single named parameter in, for example, the IN() clause of an SQL statement.

Problem

I'm getting the error "SQLSTATE[HY093]: Invalid parameter number" when I try to run the below function: ``` function add_persist($db, $user_id) { $hash = md5("per11".$user_id."sist11".time()); $future = time()+(60*60*24*14); $sql = "INSERT INTO persist (user_id, hash, expire) VALUES (:user_id, :hash, :expire) ON DUPLICATE KEY UPDATE hash=:hash"; $stm = $db->prepare($sql); $stm->execute(array(":user_id" => $user_id, ":hash" => $hash, ":expire" => $future)); return $hash; } ``` I feel like it's something simple that I'm just not catching. Any ideas?
