php无限极分类:
无限极分类重点在于表的设计:
1在model中:
class CatModel extends Model{
protected $cat = array();
public function __construct(){
parent::__construct();
$this->cats = $this->select();
}
public function getTree($parent_id=0,$lev=0){
$tree = array();
foreach($this->cats as $c){
if ($c[‘parent_id‘] == $parent_id) {
$c[‘lev‘] = $lev;
$tree[] = $c;
//再查出下层的目录拼接到一起去
$tree = array_merge($tree,$this->getTree($c[‘cat_id‘] , $lev+1));
}
}
return $tree;
}
}
2在controller中:
class GoodsController extends Controller{
public function catelist(){
$catModel = D(‘Cat‘);
$catlist = $catModel->getTree();
//print_r($catlist);
$this->assign(‘list‘,$catlist);
$this->display();
}
}
3在view中:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>管理中心 - 商品分类 </title>
<meta name="robots" content="noindex, nofollow" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link href="__PUBLIC__/Admin/styles/general.css" rel="stylesheet" type="text/css" />
<link href="__PUBLIC__/Admin/styles/main.css" rel="stylesheet" type="text/css" />
</head>
<body>
<h1> <span class="action-span"><a href="cateadd.html">添加分类</a></span> <span class="action-span1"><a href="#">管理中心</a> </span><span id="search_id" class="action-span1"> - 商品分类 </span>
<div style="clear:both"></div> </h1>
<form method="post" action="" name="listForm">
<div class="list-div" id="listDiv">
<table width="100%" cellspacing="1" cellpadding="2" id="list-table">
<tbody>
<tr>
<th>分类名称</th>
<th>商品数量</th>
<th>数量单位</th>
<th>导航栏</th>
<th>是否显示</th>
<th>价格分级</th>
<th>排序</th>
<th>操作</th>
</tr>
<foreach name=‘catlist‘ item=‘cal‘>
<tr align="center" class="0" id="tr_2">
<td align="left" class="first-cell" style="padding-left="1""> <img src="__PUBLIC__/Admin/images/menu_minus.gif" id="icon_0_1" width="9" height="9" border="0" style="margin-left:{$cal[‘lev‘]*2}em" /> <span><a href="#">{$cal[‘cat_name‘]}</a></span> </td>
<td width="10%">0</td>
<td width="10%"><span> </span></td>
<td width="10%"><img src="__PUBLIC__/Admin/images/no.gif" /></td>
<td width="10%"><img src="__PUBLIC__/Admin/images/yes.gif" /></td>
<td><span>0</span></td>
<td width="10%" align="right"><span>50</span></td>
<td width="24%" align="center"><a href="{:U(‘admin/cat/catedit‘,array(‘cat_id‘=>$cal[‘cat_id‘]))}">编辑</a> | <a href="{:U(‘admin/cat/catdel‘,array(‘cat_id‘=>$cal[‘cat_id‘]))}" title="移除">移除</a> </td>
</tr>
</foreach>
</tbody>
</table>
</div>
</form>
<include file=‘./Index:footer‘ />
</body>
</html>
效果如下:
