HTML_TreeMenu
This manual page shows the basic steps to get
HTML_TreeMenu working.
Installing the files
Before using HTML_TreeMenu, you'll have to put some files in your
project's htdocs directory:
You can get on your harddrive in
$pear_data_dir/HTML_TreeMenu
or online at the
PEAR CVS-Web.
Simple example
<?php
require_once 'HTML/TreeMenu.php';
$menu_styles = new HTML_TreeNode(array('text'=>'Styles'));
$menu_pays = new HTML_TreeNode(array('text'=>'Countries'));
$menu_restaurants = new HTML_TreeNode(array('text'=>'Restaurants'));
$menu_plats = new HTML_TreeNode(array('text'=>'Menus'));
for ($i = 1; $i < 10; $i) {
$menu_styles->addItem(new HTML_TreeNode(array('icon'=>'Image '.($i 0))));
$menu_pays->addItem(new HTML_TreeNode(array('icon'=>'Image '.($i 10))));
$menu_restaurants->addItem(new HTML_TreeNode(array('icon'=>'Image '.($i 20))));
$menu_plats->addItem(new HTML_TreeNode(array('icon'=>'Image '.($i 30))));
}
$menu = new HTML_TreeMenu();
$menu->addItem($menu_styles);
$menu->addItem($menu_pays);
$menu->addItem($menu_restaurants);
$menu->addItem($menu_plats);
// Chose a generator. You can generate DHTML or a Listbox
$tree = new HTML_TreeMenu_DHTML($menu);
echo $tree->toHTML();
?>

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();
?>
