Question

Hey guys so I have been trying to figure out why my update function wont update my database.

Here is the function:

public function update() {

    if ( is_null( $this->id ) ) triger_error ("DailyMenuItem::update(): Attempt to update a DailyMenuItem object that does not have its ID property set.", E_USER_ERROR);

    $conn = new PDO ( DB_DSN, DB_USERNAME, DB_PASSWORD );
    $sql = "UPDATE daily_menu SET date=FROM_UNIXTIME(:date), name=:name, description=:description, price=:price WHERE id = :id";
    $st = $conn->prepare ( $sql );
    $st->bindValue( ":name", $this->name, PDO::PARAM_STR );
    $st->bindValue( ":description", $this->description, PDO::PARAM_STR );
    $st->bindValue( ":price", $this->price, PDO::PARAM_INT );
    $st->bindValue( ":date", $this->date, PDO::PARAM_INT);
    $st->execute();
    $conn = null;
}

This object contains this

DailyMenuItem Object
(
[id] => 4
[name] => Smoked Chicken Baguette
[description] => w/goat cheese
[price] => 13
[date] => 1330585200
)

I get no error message. It just does not update anything. Please help 🙂

Answer 1

You don’t seem to be binding id.

Could that be your problem.
