Automatic Checkbox Save w/ jQuery

While making stuff I always try to put in little short cuts to make things go faster, whether its browsing though pages or submitting forms, everything needs sped up. While making the back-end of a discussion form, I used this to save settings without having to submit a form. It just saves everything onclick :D

PHP/HTML/JS

	## CONNECT TO DATABASE
	$connection = mysql_connect("localhost", "username", "password");
	mysql_select_db("databasename", $connection); 

<script type="text/javascript" charset="utf-8" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

<script type="text/javascript" charset="utf-8" src="http://paulor.net/inc/uploads/7235checkbox.save.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('<img src="http://paulor.net/inc/uploads/3874ajax-loader.gif" id="spinner" />').css('position','absolute').hide().appendTo('body');
	//for every field change
	$('input#crazycheckers').click(function() {
		//get element position
		var position = $(this).offset();
		//position image
		$('#spinner').css({ top: position.top , left: position.left + $(this).width() + 30 }).fadeIn();
		//ajax
		$.post('<?php echo $_SERVER['REQUEST_URI']; ?>',{
			ajax:1,
			value: $(this).val()
		},function() {
			$('#spinner').fadeOut();
		});
	});
});
</script>

	## GET CURRENT SETTINGS
	$is_q = mysql_query("SELECT * FROM `settings` WHERE `id` = '1'");
	$is = mysql_fetch_array($is_q);	

<p><input type="checkbox" name="crazycheckers" id="crazycheckers" value="1" <?php="" if($is['checkbox']="=" 1)="" {="" echo="" '="" checked="checked" ';="" }="" ?=""> class="ajax" /></p>
<p>Refresh the page to see that its still checked/unchecked</p>

save.php

## CONNECT TO DATABASE
$connection = mysql_connect("localhost", "username", "password");
mysql_select_db("databasename", $connection);
if($_GET['checked'] == "true") {
	mysql_query("UPDATE `settings` SET `checkbox` = '1' WHERE `id` = '1'");
} else {
	mysql_query("UPDATE `settings` SET `checkbox` = '0' WHERE `id` = '1'");
}

The JS

$(document).ready(function(){
	$('input#crazycheckers').click(function() {
		$.get("save.php", { checked: $(this).attr("checked") },
		function(data){
		});
	});
});

Simples :]
