object/classes not displaying...

econstu77

I am having trouble getting these classes for navbars working:

class nav_item {
	var $url;
	var $descrip;

function nav_item($u, $d) {
	$this->url = $u;
	$this->descrip = $d;
}
}

class subnav {
	var $nav;
	var $items;
	var $current = 'no';

function subnav($n) {
	$this->nav = $n;
}

function add($url, $descrip) {
	$u = '/' . $this->nav . '/' . $url;  
	$this->items[] = new nav_item($u, $descrip);
}


function echo_subnav() {
	echo '<ul>';

	$last = count($this->items);

	for($i = 0; $i < $last; $i++) {
		echo '<li>';
		echo '<a href="';
		echo $items[$i]->url;
		echo '">';
		echo $items[$i]->descrip;
		echo '</a>';
		echo '</li>';

	}
	echo '</ul>';
}
}

I add info to the subnavbars here:

//Projects Subnav
$subnav['projects'] = new subnav('projects');
$subnav['projects']->add('/cbeta/', 'CBETA');
$subnav['projects']->add('/stepup/', 'StepUp Savannah');
$subnav['projects']->add('/sandbox/', 'My Sandbox');
$subnav['projects']->add('/toys/', 'Toys');

but when I try and make a call to the info (like this):

<?php $sn = $subnav[$subnav_name]; $sn->echo_subnav(); ?>

the only html that gets generated is this:

So...I'm perplexed as to why I don't see the content of the navbars (like I added using the add() method above.)

Help!

Are these the error messages you're getting?

Notice: Undefined variable: items in c:\htdocs\test.php on line
Notice: Trying to get property of non-object in c:\htdocs\test.php on line

They're telling you that you need to change

echo $items[$i]->url;

echo $this->items[$i]->url;

Also, this line:

$u = '/' . $this->nav . '/' . $url;

adds one slash too many.
