Re: Sigma and nested blocks: replace outer block by inner one

Now I need to find a way to hide the level 1 part in some cases, but still show the level 2 part. I try to do this with the replaceBlock method, but there seems to be a mistake in my approach.

I got one step further by returning the block contents of a sub-block to the main-block processing: function output_navigation($structure, $level=0) {

    global $tpl;
    $sub_cont = "";
    foreach ($structure as $id => $entry) {
        $mainblock = "navigation_".($level+1);
        $subblock  = "navigation_".($level+2);
        // recursively parse subblocks and get contents
        if (!empty($entry['subpages']) && $tpl->blockExists($subblock)) {
            $sub_cont = output_navigation($entry['subpages'], $level+1);
        }
        if ($tpl->blockExists($mainblock)) {
            $tpl->setCurrentBlock($mainblock);
            // Try to hide the main entry:
            // replace the mainblock by the subblock
            // That's what does not work...
            if ($entry['hide'] == true && $sub_cont != "") {
                $tpl->replaceBlock($mainblock, $sub_cont, true);
                $tpl->touchBlock($mainblock);
            }
            else {
                $tpl->setVariable(array('name'.$level => $entry['name'], 'href'.$level => $entry['href']));
                $tpl->parseCurrentBlock($mainblock);
            }
        }
    }
    // return contents
    return $tpl->get($mainblock);

} Now I can get the subblock contents, but there will be no more processing after $tpl->replaceBlock is called for the first time. So the $keepContent parameter seems to work only for contents that was added to the block before replaceBlock was called. Is there a way to apply replaceBlock only to the actual loop, and not to the whole block? I would highly appreciate any idea on this! Thanks Markus
