Jag har problem med ett menysystem - får inte till det. Någom som vet vad som är fel ? Det finns en under meny under start men får inte fram den..

se Sidan http://www.adeniasystems.se/test/home/index.php

Menyn

$sql = "SELECT id, label, link_url, parent_id FROM dyn_menu ORDER BY parent_id, id ASC"; 
$items = mysql_query($sql);
while ($obj = mysql_fetch_object($items)) {
  if ($obj->parent_id == 0) {
    $parent_menu[$obj->id]['label'] = $obj->label;
    $parent_menu[$obj->id]['link'] = $obj->link_url;
  } else {
    $sub_menu[$obj->id]['parent'] = $obj->parent_id;
    $sub_menu[$obj->id]['label'] = $obj->label;
    $sub_menu[$obj->id]['link'] = $obj->link_url;
    $parent_menu[$obj->parent_id]['count']++;
  }
}
mysql_free_result($items);
 
function dyn_menu($parent_array, $sub_array, $qs_val = "menu", $main_id = "nav", $sub_id = "subnav", $extra_style = "foldout") {
  $menu = "<ul id=\"".$main_id."\">\n";
  foreach ($parent_array as $pkey => $pval) {
    if (!empty($pval['count'])) {
      $menu .= " <li><a class=\"".$extra_style."\" href=\"".$pval['link']."?".$qs_val."=".$pkey."\">".$pval['label']."</a></li>\n";
    } else {
      $menu .= " <li><a href=\"".$pval['link']."\">".$pval['label']."</a></li>\n"; 
    }
    if (!empty($_REQUEST[$qs_val])) {
      $menu .= "<ul id=\"".$sub_id."\">\n";
      foreach ($sub_array as $sval) {
        if ($pkey == $_REQUEST[$qs_val] && $pkey == $sval['parent']) {
          $menu .= "<li><a href=\"".rebuild_link($sval['link'], $qs_val, $sval['parent'])."\">".$sval['label']."</a></li>\n";
        }
      }
      $menu .= "</ul>\n";
    }
  }
  $menu .= "</ul>\n";
  return $menu;
}
 
foreach ($parent_array as $pkey => $pval) {
  if (!empty($pval['count'])) {
    $menu .= " <li><a class=\"".$extra_style."\" href=\"".$pval['link']."?".$qs_val."=".$pkey."\">".$pval['label']."</a></li>\n";
  } else {
    $menu .= " <li><a href=\"".$pval['link']."\">".$pval['label']."</a></li>\n"; 
  }}
 
if (!empty($_REQUEST[$qs_val])) {
  $menu .= "<ul id=\"".$sub_id."\">\n";
  foreach ($sub_array as $sval) {
    if ($pkey == $_REQUEST[$qs_val] && $pkey == $sval['parent']) {
      $menu .= "<li><a href=\"".rebuild_link($sval['link'], $qs_val, $sval['parent'])."\">".$sval['label']."</a></li>\n";
    }
  }
  $menu .= "</ul>\n";
  }
 
function rebuild_link($link, $parent_var, $parent_val) {
  $link_parts = explode("?", $link);
  $base_var = "?".$parent_var."=".$parent_val;
  if (!empty($link_parts[1])) {
    $link_parts[1] = str_replace("&amp;", "##", $link_parts[1]);
    $parts = explode("##", $link_parts[1]);
    $newParts = array();
    foreach ($parts as $val) {
      $val_parts = explode("=", $val);
      if ($val_parts[0] != $parent_var) {
        array_push($newParts, $val);
      }
    }
    if (count($newParts) != 0) {
      $qs = "&amp;".implode("&amp;", $newParts);
    } 
    return $link_parts[0].$base_var.$qs;
  } else {
    return $link_parts[0].$base_var;
  }
 } 
 
echo dyn_menu($parent_menu, $sub_menu, "menu", "nav", "subnav");

var_dump($parent_array) ger värdet NULL
NULL - alltså har den inget värde.. vart kan det ha gått fel nogånstans?
