子類別和子/子類別的顯示類

我的PHP初學者。我開發我的第一個動態網站 - >http://www.afrogfx.com 如果你看一下我的側邊欄，你會看到一個類別列出位於這裏我的問題，如果我創建子子類像子類別和子/子類別的顯示類

CAT A 
    - SUB CAT A-1 
    - SUB CAT A-2 
     -- SUB CAT A-3 (problem Here) 
    CAT B 
    - SUB CAT B-1 
    - SUB CAT B-2 
    - SUB CAT B-2-a 
     -- SUB CAT B-2-b (problem Here) 
     --- SUB CAT B-3 (problem Here)

類別列表代碼

<?php 
    mysql_select_db($db_name, $conn); // Change for your database 
    $query_Recordset1 = "SELECT catid,catname,parentid FROM categories "; 
    $Recordset1 = mysql_query($query_Recordset1, $conn) or die(mysql_error()); // Change for your database 


    while ($row = mysql_fetch_assoc($Recordset1)) 
    { 
    $menu_array[$row['catid']] = array('catname' => $row['catname'],'catid' =>   $row['catid'],'parentid' => $row['parentid']); 

    } 
    //recursive function that prints categories as a nested html unordered list 

    function generate_menu($parent) 
    { 
    $has_childs = false; 
    //this prevents printing 'ul' if we don't have subcategories for this category 
    global $menu_array; 
    //use global array variable instead of a local variable to lower stack memory   requierment 
    foreach($menu_array as $key => $value) 
    { 
    if ($value['parentid'] == $parent) 
    {  
    //if this is the first child print '<ul>'      
    if ($has_childs === false) 
    { 
    //don't print '<ul>' multiple times        
    $has_childs = true; 
    //echo '<ul>'; 
    echo '<ul id="categories">'; 
    } 
    echo '<li><a href="categories?catid=' . $value['catid'] . '&parentid=' .     $value['parentid'] . '&catname=' . $value['catname'] .'">' .   $value['catname'] . '</a>'; 
    echo '<input type="hidden" value="' . $value['catname'] . '" />'; 
    generate_menu($key); 

    //call function again to generate nested list for subcategories belonging to this   category 

    echo '</li>'; 
    } 
    } 

    if ($has_childs === true) echo '</ul>'; 
    } 
    //generate menu starting with parent categories (that have a 0 parent) 
    ?>

現在我需要的功能來選擇主類別中的所有話題，當我選擇它子分類爲&子分類！我該怎麼做？？！

有這樣可愛的CMS'你可以開始 – 2012-10-24 03:50:18

我不明白你@Dagon我怎麼能修好它！如果你有例子！我沒有找到我的答案@谷歌！ – ahmedhassan

我用這個代碼菜單，子菜單

這是功能

// Menu builder function, parentId 0 is the root 
function buildMenu($parent, $menu) { 
$html = ""; 
if (isset($menu['parents'][$parent])) 
{ 
    $html .= " 
    <ul>\n"; 
    foreach ($menu['parents'][$parent] as $itemId) 
    { 
     if(!isset($menu['parents'][$itemId])) 
     {  
     $html .= "<li>\n <a href='".$menu['items'][$itemId]['link']."'>".$menu['items'][$itemId]['label']."</a>\n</li> \n"; 

     } 
     if(isset($menu['parents'][$itemId])) 
     { 
     $html .= " 
     <li><span>" . $menu['items'][$itemId]['label'] . "<b></b></span>" ; 
     $html .= buildMenu($itemId, $menu); 
     $html .= "</li> \n"; 
     } 
    } 
    $html .= "</ul> \n"; 

    } 
    return $html; 
}

這是在呼叫

// Select all entries from the menu table 
$sql = "SELECT id, label, link, parent FROM dbo.Menu ORDER BY parent, sort, label"; 
$result = $database->query($sql); 
$menu = array(
'items' => array(), 
'parents' => array() 
); 
// Builds the array lists with data from the menu table 
while ($items = sqlsrv_fetch_array($result)) { 
// Creates entry into items array with current menu item id ie. $menu['items'][1] 
$menu['items'][$items['id']] = $items; 
// Creates entry into parents array. Parents array contains a list of all items with  children 
$menu['parents'][$items['parent']][] = $items['id']; 
}

我有一個SQL表在我的數據庫與列

ID
標籤
鏈接
家長
排序

如果你把父0，那麼每一個項目你想成爲擺在家長下一個子菜單所有的菜單項目的頂部父母身份證我
