/*******************************************************
* This is based on v1.0. Thanks for original code.
* v1.2 adds the ability to have a more customised look of each
* cell. I'd probably use styles to control the standard look and
* just pass the exceptions. Worth considering incorporating the here.
*
* My Changes:
* 1. Handles frames by using javascript. Change the frame names in the
* two javascript functions to your own frames and change the urls to
* some of your own and it should start working.
* 2. Handles menus's without submenus. We have significant pages which needed
* their own bar but didn't have any other options.
* 3. Handles links to external and internal pages
* 4. Added constructors to simply code
* 5. Controls appearance through styles
* 6. Makes selected items upper case, other effects may be applied.
* SubId tracks the submenu selected so that it can be highlighted.
* I've just used uppercase to highlight.
* 7. Dropped the $action parameter. It wasn't being used.
* 8. Added AutoClose to the menu parameters, allows you to keep the page
* open to add other functionality
* 9. Added a concept which started life being called fragments but which
* really just calls a separate function to allow something quite different
* to be used. In this example a cut down list of the magazine issues we
* have produced. The function returns the html. Have tried to limit the
* use of echo to a few strategic places.
*
* FINALLY as a php newbie it's been a really interesting experience getting
* this code and playing with it.

--首先請用phpmyadmin把以下資料貼進去資料庫裡以建立一資料表叫menu
-- phpMyAdmin SQL Dump
-- version 2.6.0-rc1
-- http://www.phpmyadmin.net
--
-- 主機: localhost
-- 建立日期: Dec 25, 2004, 11:16 PM
-- 伺服器版本: 4.0.20
-- PHP 版本: 5.0.1
--
-- 資料庫: `test`
--
-- --------------------------------------------------------
--
-- 資料表格式： `menu`
--
--id為流水號
--name為每個樹節點的名稱
--url為超連結
--target為目標框架頁
--parent為父節點,若為0則無父節點
--
CREATE TABLE `menu` (
`id` int(10) unsigned NOT NULL auto_increment,
`name` varchar(50) NOT NULL default '',
`url` varchar(50) NOT NULL default '',
`target` varchar(50) NOT NULL default '',
`parent` int(11) NOT NULL default '0',
PRIMARY KEY (`id`)
) TYPE=MyISAM AUTO_INCREMENT=11 ;
--
-- 列出以下資料庫的數據： `menu`
--
INSERT INTO `menu` VALUES (1, '搜尋器', '#', '_self', 0);
INSERT INTO `menu` VALUES (2, 'php網站', '#', '_self', 0);
INSERT INTO `menu` VALUES (3, 'kimo', 'http://www.kimo.com.tw', '_blank', 1);
INSERT INTO `menu` VALUES (4, 'google', 'http://www.google.com', '_blank', 1);
INSERT INTO `menu` VALUES (5, '國內', '#', '_self', 2);
INSERT INTO `menu` VALUES (6, '國外', '#', '_self', 2);
INSERT INTO `menu` VALUES (7, 'php5討論區', 'http://www.php5.idv.tw', '_blank', 5);
INSERT INTO `menu` VALUES (8, 'twbb討論區', 'http://www.twbb.org/forum/', '_blank', 5);
INSERT INTO `menu` VALUES (9, 'php.net', 'http://www.php.net', '_blank', 6);
INSERT INTO `menu` VALUES (10, 'zend', 'http://www.zend.com/', '_blank', 6);

其次,撰寫主要程式碼如下:

[Copy to clipboard]CODE:

用php製作樹狀選單

include("connection.php");//連結資料庫
makeTreeNode(0);
function makeTreeNode($id){
$rs=mysql_query("select * from menu where parent=$id");
echo "

$name

\n";
}
?>
