Lavede engang en menu, vil mene den kan det du efterlyser.
class menu{
var $menuArray,
$submenuArray;
function menu(){
$mainGroups = mysql_query("select * from menu where parent = 0 order by sort");
while ($rs = mysql_fetch_array($mainGroups)){
$this->menuArray[$rs[ID]]=$rs[Name];
}
$subGroups = mysql_query("select * from menu where parent <> 0 order by sort");
while($rs = mysql_fetch_array($subGroups)){
$this->submenuArray[$rs['parent']][$rs[ID]]=$rs[Name];
}
//print_r($this->menuArray);
//print_r($this->submenuArray);
}
function submenu($groupID){
$submenu = '<div id="sub_'.$groupID.'" class="submenu" style="visibility:hidden; display:none;">';
foreach ($this->submenuArray[$groupID] as $id=>$name){
if(array_key_exists($id,$this->submenuArray)){
$submenu.='<a href="java script: showSubMenu(\'sub_'.$id.'\');" class="menuLink">'.$name.'</a><br>';
$submenu.= $this->submenu($id);
}else{
$submenu.='<a href="?group='.$id.'" class="menuLink">'.$name.'</a><br>';
}
}
$submenu.= '</div>';
return $submenu;
}
function makeMenu(){
echo '<table cellpadding="0" cellspacing="0" border="0">';
foreach ($this->menuArray as $groupID=>$groupName){
//check if submenu exist
if(array_key_exists($groupID,$this->submenuArray)){ //submenu exist
echo '<tr><td><a href="java script: showSubMenu(\'sub_'.$groupID.'\');" class="menuLink">'.$groupName;
echo $this->submenu($groupID);
echo '</td></tr>';
}else{ //no submenu, ordinary link
echo '<tr><td><a href="?group='.$groupID.'" class="menuLink">'.$groupName.'</td></tr>';
}
}
echo '</table>';
}
function openGroup(){
$id = $_GET[group];
while($this->getParent($id)!= 0){
$id = $this->getParent($id);
echo '<script type="text/javascript">showSubMenu(\'sub_'.$id.'\');</script>';
}
}
function getParent($id){
$q = mysql_fetch_array(mysql_query("select parent from groups where groupID = $id"));
return $q['parent'];
}
}
$menu = new menu();
$menu->makeMenu();
if(isset($_GET[group])&& is_numeric($_GET[group])){
$menu->openGroup();
}
en smule javascript skal der os til:
<script type="text/javascript">
function showSubMenu(menu){
var current = document.getElementById(menu).style.visibility;
if(current=="hidden"){
document.getElementById(menu).style.visibility = "visible";
document.getElementById(menu).style.display = "block";
}else{
document.getElementById(menu).style.visibility = "hidden";
document.getElementById(menu).style.display = "none";
}
}
</script>
