Connect to MySQL Function

Antonio Ciccarone — Wed, 16 Jun 2010 21:27:21 +0000

This is how I connect to a MySQL database. The following code is based off of three or four separate php files but could insecurely be combined into one. We’ll be creating functions.php which holds all of the code that the site uses, settings.php which holds the configurable options and a connection.php that connects to the database. The fourth and obviously optional file is your index.php (or wherever you’re connecting from)

First, in functions.php we’ll define our connectSQL. It takes four arguments and connects or returns an error if unsuccessful

^?View Code LANGUAGE

function connectSQL($server, $user, $pass, $name) {
	define("DB_SERVER", $server);define("DB_USER", $user);define("DB_PASS", $pass);define("DB_NAME", $name);
	$connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS);
	if (!$connection) {
		die("Database connection failed: " . mysql_error());
	}
	$db_select = mysql_select_db(DB_NAME,$connection);
	if (!$db_select) {
		die("Database selection failed: " . mysql_error());
	}
}

In settings.php we’ll assign values to the variables. Always remember to use secure passwords.

^?View Code LANGUAGE

// Database Configuration
$database['server'] = "localhost";
$database['user'] = "xxx";
$database['password'] = "xxx";
$database['name'] = "xxx";

The actual connection code is now pretty easy to implement. You can call it whenever and however you’d like with only one line of code.

^?View Code LANGUAGE

1 2	// Connection to the database via function connectSQL($database['server'], $database['user'], $database['password'], $database['name']);

Finally, to actually use this, simply include the connection.php

^?View Code LANGUAGE

1	include 'connection.php';

I love that song. After a day of focus groups and meetings yesterday, it’s going to be nice to get back to my code and script. I’m all Realtor’d out and need some quiet time with Notepad++. I’m really looking forward to see where NAR and my company will take the Game Changer idea, it seemed to devolve and evolve yesterday with the responses of the Brokers, Agents and Assistants.

I’ve gotten most of the install portion working and learned a lot through the process, like making dynamic configuration files on the fly and code cleanliness and reusablility. Fun, fun.

Thought of a great website idea (non-real estate) yesterday, I might mock it up on paper today. Happy Hump Day!

Today I’ll be connecting to a Postgres database for the first time. I’m used to mySQL but I hear they’re basically the same when it comes down to functionality. I’ve already started working on an AJAX based property search with some sample data, so I just have to take my code off of dev.urbiance and hook it into our server.

I’m also a virgin to remote databases, it looks like the connection is working – but I haven’t queried or echoed anything yet. So far I’ve got a Javascript price slider, city selector and zip code input which send an XMLHttp request to a php page, query the property table and send the response text back into a div. Going for a completely object-oriented code structure here, wish me luck. I’ll be updating my progress and snippets along the way here on my blog.

Happy remote coding, Antonio
