Simple ajax call page??

Few things:

1st, ensure jquery is using POST not GET to send data to the server.
2nd, your getting the error because you're using object references in a file that's just a function, so this-> anything won't work
3rd, to get at the CI db stuff, you need to use a controller so instead of using something.php in your validate.js you want the remote to be your_controller/your_validation_function
