It is one thing to be able to generate a 'tree' menu with nodes, sub
nodes etc but another to be able to open and shut dynamically using
javascript. What I have done is to write a class (actually 2 classes )
that interfaces with Tigra Tree ['free']
(www.softcomplex.com/products/tigra_menu_tree/). I've added the ability
to use templates at different levels. The test program below should
give you a flavour. Ask if you want the code (11k too big for news)
<?php
/*
menu tree
---------
This example populates a 2-level tree showing employees
by department. It illustrates templates for links.
Note the order in which items are added to the tree.
Always add item to tree/parent node BEFORE adding children to it
Nodes are added as references so unset() before re-using a node
Files required
../cl/menutree.phpc
../tools/mnu/tree.js
../tools/mnu/tree_tpl.js
graphic files as specified in tree_tpl.js
*/
require_once('../cl/menutree.phpc');
// dummy data
$departments=array();
$e1=array(1=>'Peter fox',2=>'Sally Fox',3=>'Geoffrey Fox');
$e2=array(11=>'Teddy fox',12=>'Jean Fox');
$departments[1]=array('Sales',$e1);
$departments[10]=array('Production',$e2);
// set up tree and organise templates
$t = new menuTree();
$t->AddLinkTemplate(1,'');
$t->AddLinkTemplate(2,'department.php?DEPT=[DID]');
$t->AddLinkTemplate(3,'employee.php?EMPNO=[EID]');
// highest level is always shown and doesn't collapse
$tnode = new treeNode('Employees by department');
$t->AddNode($tnode);
// populate tree
foreach($departments as $did=>$dept){
$departmentName=$dept[0];
$dnode = new treeNode($departmentName,array('DID'=>$did));
$tnode->AddChild($dnode);
$employeesOfDept=$dept[1];
foreach($employeesOfDept as $eid=>$employeeName){
$dnode->AddChild(new treeNode($employeeName,array('EID'=>$eid)));
}
unset($dnode);
}
// illustrate bypassing template using blank for data key
$snode = new treeNode('something special',array(''=>'myhomepage.php'));
$tnode->AddChild($snode);
// show it
print($t->CompleteMenu());
?>
