Dynamic drop down list for different countries, states, geographic locations?

Question

I am having my users to enter their city, state, and country. But my dilemma is how to manage it dynamically so that I can control what is entered while having correct spell

Answer 1

Ok so after several hours I've written an application based on the MySQL world database: MySQL world Setup

The code for the entire application is way to large to put in an answer so I'll provide Pastebin links for each seperate file, aswell as a link to a working example of the script and a download link for the Zip archive.

I'm sure the code can be improved further, but I'll leave that up to you.

Requirements: MySQL world Database / jQuery

1. index.html: index.html
2. style.css: style.css
3. country.js: country.js
4. dbconnect.php: dbconnect.php
5. get_country.php: get_country.php
6. get_states.php: get_states.php
7. get_city.php: get_city.php
8. get_data.php: get_data.php

Working Example:

9. Country, State, City selector

Zip Archive Download (DB NOT included!):

10. selector.zip (currently down)
11. Virus Total Analysis of above file

I'm working on an updated script due to the popular demands on this question. It will be added soon.
