Dear MODx programmers,
I'm trying to add a '&hierarchical' option to the GalleryAlbums snippet and am almost ready, but run into a problem I can't solve myself.
I have a recursive function that gets an album object as array and outputs a <ul>-based tree (unsing chunks) for that resource. My problem is that it can't access some important variables outside of itself; declaring them as global doesn't help:
function process_children ($album) {
global $modx;
global $rowTpl; // These two don't work.
global $wrapperTpl; // ^^^
global $outputSeparator;
// global $albumChildren; // This one is visible though...
$tree = '';
if ($albumChildren[$album['id']]) {
$modx->log(modX::LOG_LEVEL_ERROR, "Found child");
foreach ($albumChildren[$album['id']] as $descendants) {
$tree .= process_children ($descendants) . $outputSeparator;
}
return $modx->getChunk($wrapperTpl, array('rows' => $tree));
} else {
$modx->log(modX::LOG_LEVEL_ERROR, "Found row, $rowTpl");
$tree = $modx->getChunk($rowTpl, $album) . $outputSeparator;
return $tree;
}
}
Please also note that the function declaration is inside such block:
if ($hierarchical) {
..
}
