some issues with switch()

[Guber-X]

As far as it goes for me I have the switch() working, but not to what im trying to do. This is for a "media" page where I have 3 different categories "Music", "Videos" and "Photos". I'm trying to get it so when you goto the "Media" page it will show just the 3 categories, that section works but it is also showing the sub categories for all them categories. So for what im trying to do is when viewing the "media" page, it will display the 3 categories, then when selecting the category it will display the "sub categories". and then when you select the "sub category" it will display the contents of that "sub category"

 

should i be trying to do this a different way? or do i have something wrong here? lol

 

here is my switch() code

<?php
$cat = (isset($_GET["m_cat"])) ? (intval($_GET["m_cat"])) : 0;
 switch($_GET["b"]=="true")
	{
		default :
		if("/ffy/media.php"==$_SERVER['PHP_SELF'])
			{
				echo "Select a Category";
			}

		case "false":
		if($_GET["m_cat"]==$cat)
			{

				echo "<font size='3'>";
				$dcat = mysql_query("SELECT * FROM media_sub_cat WHERE m_cat=$cat")
					or die("mySQL Query Failed: " .mysql_error());

				while($catrow = mysql_fetch_array($dcat)) {
					list($id, $m_sub_cat, $m_cat) = $catrow;

				echo ": <font class='myFont'><a href='media.php?b=true&cat=".$m_cat."&subcat=".$m_sub_cat."'>".$m_sub_cat."</a></font> ";
				}
			echo ":</font>";
			echo "Work Damb You";
			}
		break;

		case "true":
		if($_GET["cat"]==$cat && $_GET["subcat"]==$m_sub_cat)
			{

				echo "Weird...";

			}
		break;
	}
?>

switch($_GET["b"]=="true")

 

This is improper syntax, use this instead:

 

switch($_GET['b'])
