PHP: nested menu with a recursive function, expand only some nodes (not all the tree)

Question

I have this array, called $nested (it\'s a long one, but I tried to get a comprehensive scenario):

Array
(
    [1] => Array
        (
                


        

Answer 1

At last that's what I did, it works very fine:

// create array of ancestors' ID from current page
function path($page = 0) {
    global $database_connApp, $connApp;
    // let's create arrays
    do {
        mysql_select_db($database_connApp, $connApp);
        $query_rsPage = "SELECT pages.pag_id FROM pages WHERE pages.pag_id = " . $page;
        $rsPage = mysql_query($query_rsPage, $connApp) or die(mysql_error());
        $row_rsPage = mysql_fetch_assoc($rsPage);
        $bid[] = $row_rsPage['pag_id'];
        $page = $row_rsPage['pag_parent'];
    } while ($page > 0);

    // move to the last array index
    end($bid);
    $output = $bid;
    return $output;
}

// create the menu
function fmenu($parent, $array, $path) {
    $has_children = false;
    foreach($array as $key => $value) {
        if (in_array($value['parent'], $path)) {
            if ($value['parent'] == $parent) {
                if ($has_children === false && $parent) {
                    $has_children = true;
                    echo '
' ."\n";
                }
                $active = ($_GET['iData'] == $value['id']) ? ' class="active"' : '';
                echo '' . "\n";
                    echo '' . html($value['title']) . '' . " \n";
                echo "\n";
                    fmenu($key, $array, $path);
                echo "\n";
            }
        }
    }
    if ($has_children === true && $parent) echo "
\n";
}

echo fmenu(0, $nested, path($row_rsEdit['pag_id']));
