Hi folks,

a customer has a large Gallery using G2 that isn't embedded in the rest of his web page yet. Now, I have to show a simple page in the page's style that shows a treeview of available albums (and perhaps the number of containing items).

I've already found some examples that show how to integrate G2 into a page but I didn't found
how I can show a treeview.

Can somebody give me a hint?

Thanks in advance,
Johannes

I just did this for G2Image v3.0. Take a look at g2ic_make_html_album_tree in g2image.php. I used the dtree script (like the album select module does).

You'll need to modify the link generated in g2ic_make_html_album_tree_branches to fit your needs.

Hope that helps or points you in the right direction.

Hi Kirk,

many thanks for the tip, your code was very useful for me.
For the ones who are looking for the same solution, here is my heavily changed code from Kirk:

(This is only a quick & dirty pre-solution ;)

<html>
<head>
<title>Test</title>
</head>

<body>

<?php

runGallery();

function runGallery() {

require_once('../embed.php'); // change this!

$init = GalleryEmbed::init(array('fullInit' => true));

if (GalleryUtilities::isCompatibleWithApi(array(7,5), GalleryCoreApi::getApiVersion())) {
list($error, $rootAlbum) = GalleryCoreApi::getDefaultAlbumId();
}
// Otherwise use a Gallery2 2.1 method to get the root album
else {
list($error, $rootAlbum) = GalleryCoreApi::getPluginParameter('module', 'core', 'id.rootAlbum');
}

print g2ic_make_html_album_tree($rootAlbum);

}

function g2ic_make_html_album_tree($root_album){

$parent = -1;
$node = 0;
$html .= g2ic_make_html_album_tree_branches($root_album, $parent, $node);
return $html;
}

function g2ic_make_html_album_tree_branches($current_album, $parent, &$node) {

// global $g2ic_options;

list ($error,$items) = GalleryCoreApi::loadEntitiesById(array($current_album));
if(!$error){
foreach ($items as $item) {
$album_title = $item->getTitle();
if(empty($album_title)) {
$album_title = $item->getPathComponent();
}
}

$html .= "<ul>".
"<li>$album_title</li>";

}

list($error, $sub_albums) = GalleryCoreApi::fetchAlbumTree($current_album,1);

$albums = array_keys($sub_albums);

if (count($albums) > 0) {
$parent = $node;
foreach ($albums as $album) {
$node++;
$html .= g2ic_make_html_album_tree_branches($album, $parent, $node);
}
}

$html .= "</ul>";

return $html;
}

?>
