php - ternary operator in a dynamic dropdown menu -

i'm still having trouble adding ternary operator menu. it's purpose add class=active li tag if menuid , page id same. pageid stored in var called thispage... when thispage , menuid equal should class tag.

i've included code , php dump determine issue

the line of code have issue ternary operator in ///sub menu & ///main menu sections starting

($thispage==$sval['menuid'] ? ' class="active"' : '')   

i think "$sval['menuid']" problem.

 <?php 

$thispage=3; //

    $sql = "select menuid, menutitle, menuurl, menuparentid, menuorderid menu order menuparentid, menuorderid asc";     $items = mysql_query($sql);     while ($obj = mysql_fetch_object($items)) {         if ($obj->menuparentid == 0) {             $parent_menu[$obj->menuid]['menuid'] = $obj->menuid;             $parent_menu[$obj->menuid]['menutitle'] = $obj->menutitle;             $parent_menu[$obj->menuid]['link'] = $obj->menuurl;         } else {             $sub_menu[$obj->menuid]['menuid'] = $obj->menuid;             $sub_menu[$obj->menuid]['parent'] = $obj->menuparentid;             $sub_menu[$obj->menuid]['menutitle'] = $obj->menutitle;             $sub_menu[$obj->menuid]['link'] = $obj->menuurl;             if (!isset($parent_menu[$obj->menuparentid]['count'])) {                 $parent_menu[$obj->menuparentid]['count'] = 0;             }             $parent_menu[$obj->menuparentid]['count']++;         }     }      mysql_free_result($items);       function create_menu($parent_array, $sub_array, $qs_val = "menu", $main_id = "nav", $sub_id = "dropdown-menu", $dd_style = "dropdown")     {         $menu = "<ul class=\"{$main_id}\">\n";          foreach ($parent_array $pkey => $pval) {             if ( ! empty($pval['count'])) {                              //drop-down menus                 $menu .= "\t<li class=\"{$dd_style}\"><a href=\"{$pval['link']}\" class=\"dropdown-toggle\" data-toggle=\"$dd_style\">{$pval['menuid']} - {$pval['menutitle']}<b class=\"caret\"></b></a>\n";                 $menu .= "\t\t<ul class=\"{$sub_id}\">\n";                  foreach ($sub_array $sval) {                     if ($pkey == $sval['parent']) {  ///////////////////////////////////////sub menus                         $menu .= "\t\t\t<li" .
