That is some classy code...

Thanks to Andreas D. for sending this one in. This PHP code generates a heirachical menu in a not so nice way.
- WTF #1 is for being very 'fugly' code. Nobody should indent with more than 4 spaces!
- WTF #2 is the
menuclass. This class really has no point other than to hold two values which can be done with a simple array. See my example below. - WTF #3 is this
$menu[$i][$j][0][0][0]->target. There's nothiing like a 5 dimensional array to make a really simple thing like menu generation really difficult.
Be sure to shield your eyes and don't look directly at this code...
<?php
class menu{
var $name;
var $target;
function menu($name, $target){
$this->name = $name;
$this->target = $target;
}
}
function drawMenu(){
global $menu, $active_menu;
$kat=$active_menu["kat"];
while (list($i) = each($menu)) {
if ($i == $kat) {
//category title
//PrintMenuTitle($menu[$i][0][0][0][0]->name);
$menu[$i][0][0][0][0]->name;
//level-1
while (list($j) = each($menu[$kat])) {
if ($j > 0) {
PrintMenu(1, $menu[$i][$j][0][0][0]->name, $menu[$i][$j][0][0][0]->target, (($j == $active_menu["sub1"]) ? 1 : 0));
//level-2
if ($j == $active_menu["sub1"]){
while (list($k) = each($menu[$kat][$j])) {
if ($k > 0) {
PrintMenu(2, $menu[$i][$j][$k][0][0]->name, $menu[$i][$j][$k][0][0]->target, (($k == $active_menu["sub2"]) ? 1 : 0));
//level-3
if ($k == $active_menu["sub2"]){
while (list($l) = each($menu[$kat][$j][$k])) {
if ($l > 0) PrintMenu(3, $menu[$i][$j][$k][$l][0]->name, $menu[$i][$j][$k][$l][0]->target, (($l == $active_menu["sub3"]) ? 1 : 0));
}
}
}
}
}
}
}
PrintEnding();
}
}
}
function PrintMenu($level, $name, $target, $active) {
switch ($level) {
case 1:
$width = 0;
break;
case 2:
$width = 15;
break;
case 3:
$width = 30;
break;
/*

$size = "small";
$width = 22;
$width2 = 6;
$align = "right";
$arrowwidth = 3;
$arrowheight = 5;
$paddingtop = 6;
$class = "subnav";
break;
case 4:
$colspan = array(4,2,1);
break;

}
$highlight = (($active == 1) ? "on" : "off" );

Usually when I do recursive menus I use arrays and do something like this. There are probably much better techniques but this is an example of something fairly simple.
<?php
/**************************************************************
Some quick example code demonstrating how to
generate a recursive menu script
**************************************************************/
function menu($name,$URL = null)
{ /* Helper function to reduce the number of times we have to
type array(...). This also cuts down on the # of bugs
*/
return array('name' => $name,
'URL' => $URL,
'children' => array() // blank for now.
);
}
function printMenu(&$children)
{
// HTML here for the sake of example. Normally I would avoid
// this. :)
echo '<ul>';
foreach ($children as $id => $child)
{
if ($child['URL'] != null) {
printf('<li><a href="%s" id="%s">%s</a></li>',$child['URL'],
htmlentities($id),htmlentities($child['name']));
} else {
printf('<li>%s</li>',htmlentities($child['name']));
}
echo "\n"; // so we have some nice HTML :)
// here's the recursion.
if (count($child['children']))
printMenu($child['children']);
}
echo "</ul>\n";
}
// This is where we define the menu.
$menu = menu('Root','/');
$menu['children']['c1'] = menu('About PHPWTF','/about');
$menu['children']['c2'] = menu('Categories');
$menu['children']['c2']['children']['c2s1'] = menu('Wonky Code','/taxonomy/term/3');
$menu['children']['c2']['children']['c2s2'] = menu('Bad Architecture','/taxonomy/term/1');
$menu['children']['c2']['children']['c2s3'] = menu('Hall of Fame','/taxonomy/term/7');
// etc.
$menu['children']['c3'] = menu('RSS Feeds');
$menu['children']['c3']['children']['c3s1'] = menu('RSS');
$menu['children']['c3']['children']['c3s1']['children']['rss1'] = menu('RSS 0.92','/node/feed');
$menu['children']['c3']['children']['c3s1']['children']['rss2'] = menu('RSS 1.0','/index.rdf');
$menu['children']['c3']['children']['c3s1']['children']['rss3'] = menu('RSS 2.0','/rss2.xml');
$menu['children']['c3']['children']['c3s2'] = menu('Atom','/atom.xml');
// etc.
// recursion
printMenu($menu['children']);
?>
The above will generate this:
- About PHPWTF
- Categories
- RSS Feeds
