Ohh, I think I see now; in the first var declaration, you have a semicolon at the end of the first line, so the var casting isn't applied to the other two variables declared (including result/success). Try fixing that to see if that helps anything; without the var, the scoping gets confusing.

Sorry if this isn't descriptive enough, if I were on the computer, I would copy the block I'm referencing.

Thanks for pointing that out! Sadly it's still returning False.

function getLocation(address)
{
	var location = (address) ? address : $('#location-input').val(),
		locationChanged = (address && lastLocation != location) ? true : locationChanged,
		success = false;

	var request = {
		origin: location, 
		destination: '52.697605, -2.021616',
		travelMode: g.DirectionsTravelMode.DRIVING
	};
	
	if (locationChanged && lastLocation != location)
	{
		$('#spinner').fadeIn(200);
		
		directions.route(request, function(response, status)
		{
			if (status == 'OK')
			{
				var route = response.routes[0];
					addressName = route.legs[0].start_address,
					lastLocation = (address) ? location : addressName;
				
				$('#location-input').removeClass('error').val(addressName);
			
				map.setMapTypeId(g.MapTypeId.ROADMAP);
				directionsDisplay.setDirections(response);
				
				locationChanged = false;
				success = true;
			}
			else if (status == 'OVER_QUERY_LIMIT') { alert('The server could not be reached, please try again later!'); }
			else { $('#location-input').addClass('error'); }
			
			$('#spinner').fadeOut();
		});
	}
	
	console.log(success);
	return success;
}

Changed code.

Is there a list/sql table of all the areas/locations in New York?

This could be useful. It's used on Steam as well.

yeah but i need it like more of a table:
id - areaname - parentlocation

type of thing, that seems kinda complicated..

[QUOTE=NorthernGate;32254659]Any of you guys have any experience or tips on converting a custom website to a drupal theme? I despise drupal with most of the fibers in my being, but the company is insisting on using drupal for now. So I have to convert all the work I've done thus far into a drupal theme. Bleh. And drupal isn't cooperating as well as I might have hoped.[/QUOTE]

Heh, it's actually my favourite CMS.

Drupal 6 or 7?

Generally I just modify the default page.tpl.php ([url]http://api.drupal.org/api/drupal/modules--system--page.tpl.php/7/source[/url]), stripping out all of the HTML used for layout, and then write my theme around each output function.

If you aren't as familiar with Drupal, it might be easier to develop a static HTML/CSS page then replace the different page sections (footer, sidebar, navbar etc) one by one with Drupal output (regions and variables).

Let me know if you have any specific questions.

[QUOTE=Ac!dL3ak;32247335]OOOH i know

pick me

when you define the callback function for directions.route, it will not be run in the same (scope, i guess?) as where you defined route as false before. Since that route never changes, it will always turn false and the object route off of window might have the actual route information

just a thought[/QUOTE]

How are my skills? (Sample code)

function login($username = false, $password = false) {
    global $dbh, $loginErrors;
    $dbPassword = NULL;

    $sql = "SELECT id, username, password FROM accounts WHERE username = :username";

    try {

        $query->bindParam(':username', $username, PDO::PARAM_STR, 24);

        $query->execute();
        $numRows = $query->rowCount();  // getting number of rows returned
    } catch (PDOException $e) {
        //echo $e->getMessage(); need some way of logging this error, db maybe?
        echo 'PDO error in f.login 1!'; // temporary till I figure something out
    }

    //echo $numRows . '<br />' . $username;

    if ($numRows == 1) {    // if user exists. could also just do if($numRows){}
        try {
            $fetch = $query->fetch(PDO::FETCH_ASSOC);

            $dbId = $fetch['id'];
            $dbUsername = $fetch['username'];
            $dbPassword = $fetch['password'];   // assigning dbPassword from assoc array

            if (enc($password) == $dbPassword) {     // if entered password matches db password
                setCookies($dbId, $dbUsername, $dbPassword);
                header("Location: index");
            } else {

    }
}

function verifyLoggedIn() {     // check if user is logged in
    global $dbh;

        }

        return FALSE; // cookies aren't set
    }
}

function enc($string) {
    global $config;

    $hash = md5("$config[salt] $string");

    return $hash;
}

// in a global file:
if (verifyLoggedIn()) {
    $getInfo = new GetUserInfo($_COOKIE['username']); // remember, verifyLoggedIn makes sure the username is valid
}

// made this class myself, without any help, pretty proud of it
class GetUserInfo {

    public $uid, $username, $password, $email, $rank, $location, $age, $gender, $regDate, $lastLogin;

    public function __construct($username) {
        global $dbh;

        $sql = "SELECT * FROM accounts WHERE username = :username";

        try {
            $query = $dbh->prepare($sql);
            $query->bindParam(':username', $username, PDO::PARAM_STR, 24);
            $query->execute();

            $fetch = $query->fetch(PDO::FETCH_ASSOC);
        } catch (PDOException $e) {
            echo "PDO error in getUserInfo";
        }

        $this->uid = $fetch['id'];
        $this->username = $fetch['username'];
        $this->password = $fetch['password'];
        $this->email = $fetch['email'];
        $this->rank = $fetch['rank'];
        $this->location = $fetch['location'];
        $this->age = $fetch['age'];
        $this->gender = $fetch['gender'];
        $this->regDate = $fetch['reg_date'];
        $this->lastLogin = $fetch['last_login'];
    }

}

Just some little snippets. I wanted to try my traditional style of a login script except this time using PDO. This code isn't made for a huge public website, I know. And the verifyLoggedIn function could do with more advanced techniques.

I've been learning php on/off for the past month starting with only basic c++ knowledge.

One last thing: I kind of want to build website back-ends as a side job. It's fun and makes me think. But what would you guys recommend I learn next to be able to do this for people? Think I am lacking in the advanced concepts department.

Line 22 is going to cause a fatal error if a PDO exception is thrown, as $query won't be defined and you're trying to access a function. Also, why are you not handling the exception properly? Please get an exception handler or just stop execution, continuing on is bad.

I don't see a problem in updating your php's ini file:

short_open_tag = on

Why do people think that short tags are bad, maybe because some people can't edit their php ini? If that is the case then it's clear you are using a shared webhost which is a greater cause of a slow and painful death.

Mainly because they conflict with XML processing instructions, if the server has short tags enabled you have to write out the XML PIs via echo instead of just using them normally.

Edit: Also, short tags are a configuration option, while normal tags will always be supported. So not using them helps portability.
