Edited on 2009-09-04 10:28:09 by FaKn [works as a real plugin and with template support for wikka 1.2]Additions:
At the time only a dirty hack to show categories as a tree, initiated by LeOn, converted into a plugin by FaKn
The results are presented [[http://www.net4lawyer.com/openlaw here]].
====Implementation for Wikka 1.2====
Save the following as plugins/actions/categorytree.php
<?php
/**
* Displays a tree of all categories.
* For more info, see http://wikkawiki.org/CategoryTree
**/
if (!function_exists('f_action_categorytree_get_tree')) {
function f_action_categorytree_get_tree ($wakka) {
$imgpath = $wakka->GetThemePath()."/images/";
f_action_categorytree_get_level($wakka, 1, "CategoryCategory");
f_action_categorytree_get_level($wakka, 1, "KategorieKategorie");
function f_action_categorytree_is_parent ($name) {
function f_action_categorytree_get_level($wakka, $level, $parent = "CategoryCategory") {
$imgpath = $wakka->GetThemePath()."/images/";
if ($wakka->CheckMySQLVersion(4,0,1)) $results = $wakka->FullCategoryTextSearch($page);
else $results = $wakka->FullTextSearch($page);
if (f_action_categorytree_is_parent($val)) { // if element has children
// last empty element
if (($val == $active[$level]) and (f_action_categorytree_is_parent($val))) {
f_action_categorytree_get_level($wakka, $level+1, $active[$level]);
}
print f_action_categorytree_get_tree($this);
?>%%
Create a new custom theme (if you have not done this yet) by copying e.g. the 'light' theme from the 'templates' folder into 'plugins/templates'.
Append the following at the end of header.php
<div id="tree"><?php echo $this->Action('categoriestree') ?></div>%%
Now you only need some images (for example you can download all needed files here: http://www.polskieustawy.com/pics/tree/) and manipulations on wikka.css to see the right tree generated from your categories.
A simple addition to your copy of light.css is:
%%(css)
#tree {
border-right: 1px solid #DDD;
width: 200px;
padding: 10px 10px 10px 10px;
float: left;
}%%
Finally, switch to the new theme (either via your User settings or in the config, see http://docs.wikkawiki.org/WikkaThemes for more info).
====Implementation for Wikka 1.1.6.3====
This is the old code that works without plugins and templates:

====Implementation for Wikka 1.1.6.3====
This is the old code that works without plugins and templates:
Deletions:
The results are presented [[http://www.net4lawyer.com/openlaw here]]. At the time I call it "dirty hack", because it doesn't match the idea of WikkaWiki to use plugins / actions for Wikka expansions. Maybe somebody could help to make this hack better (and become to be a nice action).
**Implementation**:
As a start I put here only the code (all comments and instructions based on Wikka 1.1.6.3.):
No Differences
Additions:
**To do**:
1) Function to follow the navigation with the tree
If i open a page, that has an place in the tree, i would like to find it and show the tree open at the right place...
2) More precise documentation.
