mysqli prepared query question

From: David M.
Sent on: Thursday, November 20, 2008 4:35 PM
I'm wrestling my way into the world of mysqli, especially prepared queries.  This is also my first foray into an Object Oriented approach/style.

Here's my current roadblock that I seem to be stuck on: I am trying to create a simple, 'prepared statements'-type query (SELECT Name FROM organizations WHERE ID = ?).  The only way I can get this to work is to not only use 'bind_param' (to bind a variable to the 'WHERE ID = ?' part of the query) but also use the 'bind_result' method.  If I don't do this, I get no results.

I've been messing around with this so much that I no longer have a true sample to offer.  But here's something close to what I've been doing (you'll notice a lot of book-type names of variables):

// Connect
$mysqli = new mysqli("localhost", "me", "supersecret", "thedatabase");

// Prepare query
$stmt = $mysqli->prepare("SELECT Name FROM organizations WHERE ID=?");

$stmt->bind_param("i", $TheID);

$TheID = 15;

// Execute

// Show results (or not!) -- why doesn't this work?
$row = $stmt->fetch_row();

// If I use bind_result, it works

print_r($NewRsult);     // Yeah!

Why might this be?
