query string and sub-queries

[generic]

Hi,

I'm trying to break down sections and sub-sections using query strings in the url. Here's what I've got working so far:

// grab url variables
$_GET['manufacturer'];

// if $manufacturer is 'foo', then load 'bar'
if ($manufacturer == hunter_douglas) {
	  echo "<p>Manufacturer: Hunter Douglas</p>";
	  echo "<p>details on hunter douglas products...</p>";
	  echo "<p><a href=\"TEMP_blinds.php\">« view all manufacturers</a></p>";
	} elseif ($manufacturer == levelor) {
	  echo "<p>Manufacturer: Levelor</p>";
	  echo "<p>details on levelor products...</p>";	  

	  echo "<p><a href=\"TEMP_blinds.php\">« view all manufacturers</a></p>";	  

	} elseif ($manufacturer == shadeomatic) {
	  echo "<p>Manufacturer: Shade-o-matic</p>";
	  echo "<p>details on shade-o-matic products...</p>";	 
	  echo "<p><a href=\"TEMP_blinds.php\">« view all manufacturers</a></p>";	  

	} else { // none selected, show default
	  echo "<p>Select a manufacturer:</p>";
	  echo "<ul>";
	  echo "<li><a href=\"TEMP_blinds.php?manufacturer=hunter_douglas\">Hunter Douglas</a></li>";
	  echo "<li><a href=\"TEMP_blinds.php?manufacturer=levelor\">Levelor</a></li>";
	  echo "<li><a href=\"TEMP_blinds.php?manufacturer=shadeomatic\">Shade-o-matic</a></li>";
	  echo "</ul>";
	 }

How can I add another sub-section? Once in the selected section, I'd like to be able to show more options. Something like Apples as shown below:

FRUITS
- Oranges
- Apples
	- Macintosh
	- Green
	- Red Delicious

I had tried to grab $line using the following but no dice:

$_GET['manufacturers'];
$_GET['line'];

if ($manufacturer == hunter_douglas) {
	  echo "<p>Manufacturer: Hunter Douglas</p>";
	  echo "<p>details on hunter douglas products...</p>";
	  echo "<p><a href=\"TEMP_blinds.php&manufacturer=hunter-douglas&line=vignette\">Vignette Series</a></p>";
	  echo "<p><a href=\"TEMP_blinds.php\">« view all manufacturers</a></p>";
	  	if ($manufacturer == hunter_douglas) && ($line == vignette) {
	  		echo "Hunter-Douglas Vignette series blinds."; } // no dice
	} elseif ... etc ...

If I try to going to ?manufacturer=whoever?line=whatever, it just dumps me back to the default.

Hopefully that makes sense. Thanks in advance for any help!

Ok, I got it... I laid it out all wrong :rolleyes: . Thanks anyway!

if ($manufacturer == hunter_douglas && $line == vignette) {
}

would work

It's all working now - for posterity, here's a snip of what I'm using:

// grab url variables
$_GET['manufacturer'];
$_GET['line'];

// if $manufacturer is 'foo', then load 'bar'
if ($manufacturer == hunter_douglas) {
	if ($line == vignette) { // if current manufacturer $line is 'foo', then load 'bar'
		echo "<h2>Hunter-Douglas Vignette series blinds</h2>";
		echo "<p>details on product line</p>";		
		echo "<p><a href=\"TEMP_blinds.php?manufacturer=hunter_douglas\">&#0171; back to Hunter-Douglas</a></p>";
		echo "<p><a href=\"TEMP_blinds.php\">&#0171; view all manufacturers</a></p>";
	} elseif ($line == remembrance) {
		echo "<h2>Hunter-Douglas Remembrance series blinds</h2>";
		echo "<p>details on product line</p>";		
		echo "<p><a href=\"TEMP_blinds.php?manufacturer=hunter_douglas\">&#0171; back to Hunter-Douglas</a></p>";
		echo "<p><a href=\"TEMP_blinds.php\">&#0171; view all manufacturers</a></p>";
	} else {
	  echo "<p>Manufacturer: Hunter Douglas</p>";
	  echo "<p>details on hunter douglas products...</p>";
	  echo "<ul>";
	  echo "<li><a href=\"TEMP_blinds.php?manufacturer=hunter_douglas&line=vignette\">Vignette Series</a></li>";
	  echo "<li><a href=\"TEMP_blinds.php?manufacturer=hunter_douglas&line=remembrance\">Remembrance Series</a></li>";
	  echo "</ul>";
	  echo "<p><a href=\"TEMP_blinds.php\">&#0171; view all manufacturers</a></p>"; }
} elseif ($manufacturer == levelor) {
	  echo "<p>Manufacturer: Levelor</p>";
	  echo "<p>details on levelor products...</p>";	  

	  echo "<p><a href=\"TEMP_blinds.php\">&#0171; view all manufacturers</a></p>";	  

} elseif ($manufacturer == shadeomatic) {
	  echo "<p>Manufacturer: Shade-o-matic</p>";
	  echo "<p>details on shade-o-matic products...</p>";	 
	  echo "<p><a href=\"TEMP_blinds.php\">&#0171; view all manufacturers</a></p>";	  

} else { // none selected, show default
	  echo "<p>Select a manufacturer:</p>";
	  echo "<ul>";
	  echo "<li><a href=\"TEMP_blinds.php?manufacturer=hunter_douglas\">Hunter Douglas</a></li>";
	  echo "<li><a href=\"TEMP_blinds.php?manufacturer=levelor\">Levelor</a></li>";
	  echo "<li><a href=\"TEMP_blinds.php?manufacturer=shadeomatic\">Shade-o-matic</a></li>";
	  echo "</ul>";
}
