Question

Is it possible to submit data with PDO and having the class variables private instead of public?

I’d like to be able to use prepare and execute, in execute it’s just array($classObject), but it has to have public variables. Is there a way to use private variables and still use prepare and execute?

Example:

$query = $this->handle->prepare("INSERT INTO `$table` ($fields) VALUES ($values)");
$query->execute(array($data));

You are looking to bind data to parameters in the query:

$value = 'Test';
$smt = $this->handle->prepare("
    INSERT INTO `$table` ('field1') VALUES (:value1)");
$smt->execute(array( ':value1' => $test ));

In the example I’ve used a single variable, but the example can be simple expanded to arrays, just by imploding them:

$data = array( 'field1' => 'Foo', 'field2' => 'Bar' );

$columns = implode( ", ", array_keys( $data ) );
$values  = ':' . implode( ", :", array_keys( $data ) );

$smt = $this->handle->prepare("
   INSERT INTO `$table` ($columns) VALUES ($values)");
$smt->execute($data);
