Tree-construction methods
Actually, you have three different methods to build the tree:
By hand
This is the 'hard' way, like the example above. You have to set each node by hand.
Importing XML
You can import a formatted XML file into the tree structure. It supports string of XML_Tree object :)
XML Format
<treemenu>
<node text="First node" icon="folder.gif" expandedIcon="folder-expanded.gif" />
<node text="Second node" icon="folder.gif" expandedIcon="folder-expanded.gif">
<node text="Sub node" icon="folder.gif" expandedIcon="folder-expanded.gif" />
</node>
<node text="Third node" icon="folder.gif" expandedIcon="folder-expanded.gif">
</treemenu>
Example with a string (not tested)
<?php
require_once 'HTML/TreeMenu.php';
// Load the XML file
$xml = file_get_contents('tree.xml');
$menu = new HTML_TreeMenu();
$menu->createFromXML($xml);
// Chose a generator. You can generate DHTML or a Listbox
//$tree = new HTML_TreeMenu_Listbox($menu);
$tree = new HTML_TreeMenu_DHTML($menu);
echo $tree->toHTML();
?>
