php无限极分类:

无限极分类重点在于表的设计:

php无限极分类以及递归(thinkphp)

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:
