Hi, I've been working on a site that sends data with jQuery Ajax to a url: profile.php

I'm having some trouble retrieving this data on the PHP page, profile.php



Here is profile.php (the part that is not working)




PHP Code:
$previouschoice $_POST['data'];

if (
$previouschoice == 'blueBGhas: "yes"')

{

$superSTRsql "UPDATE Customize SET BlueBGhas='yes' WHERE Username = '$username'";

$superSTRsql1 "UPDATE Customize SET YellowBGhas='no' WHERE Username = '$username'";

$superSTRsql2 "UPDATE Customize SET GreenBGhas='no' WHERE Username = '$username'";

$superSTRsql3 "UPDATE Customize SET RedBGhas='no' WHERE Username = '$username'";

$superSTRsql4 "UPDATE Customize SET PurpleBGhas='no' WHERE Username = '$username'";

$superSTRsql5 "UPDATE Customize SET BlackBGhas='no' WHERE Username = '$username'";

mysql_query($superSTRsql$connection);

mysql_query($superSTRsql1$connection);

mysql_query($superSTRsql2$connection);

mysql_query($superSTRsql3$connection);

mysql_query($superSTRsql4$connection);

mysql_query($superSTRsql5$connection);

}

else if (
$previouschoice == 'greenBGhas: "yes"')

{

$superSTRsql "UPDATE Customize SET BlueBGhas='no' WHERE Username = '$username'";

$superSTRsql1 "UPDATE Customize SET YellowBGhas='no' WHERE Username = '$username'";

$superSTRsql2 "UPDATE Customize SET GreenBGhas='yes' WHERE Username = '$username'";

$superSTRsql3 "UPDATE Customize SET RedBGhas='no' WHERE Username = '$username'";

$superSTRsql4 "UPDATE Customize SET PurpleBGhas='no' WHERE Username = '$username'";

$superSTRsql5 "UPDATE Customize SET BlackBGhas='no' WHERE Username = '$username'";

mysql_query($superSTRsql$connection);

mysql_query($superSTRsql1$connection);

mysql_query($superSTRsql2$connection);

mysql_query($superSTRsql3$connection);

mysql_query($superSTRsql4$connection);

mysql_query($superSTRsql5$connection);

}



//Another few lines later...





if ($blueBGhas == 'yes')

{

echo 
'<style>body { background: blue; }</style>';

}

else if (
$greenBGhas == 'yes')

{

echo 
'<style>body { background: green; }</style>';






Just to make sure, here is my jQuery Ajax code:




Code:
//AJAX STUFF

		$(document).ready(function()
		
		{
		
		$('#bluebgradio').click(function()
		
		{
		
		$.ajax(
		
		{
		
		type: "POST",
		
		url: "profile.php",
		
		data: {blueBGhas: "yes"}

		});

		});

		$('#greenbgradio').click(function()
		
		{
		
		$.ajax(
		
		{
		
		type: "POST",
		
		url: "profile.php",
		
		data: {greenBGhas: "yes"}

		});

		});

		});
