How to $_POST Ajax data?

[zingzing45]

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:

//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"}

		});

		});

		});
