无限分类方法大全

1）

视图：

<select name="command">
<option>选择操作</option>
<?php foreach ((array)$datalist as $row):?>
<option><?php echo $row['str_repeat'].$row['catalog_name_alias'] ?></option>
<?php endforeach;?>
</select>

2.控制器里面去取$datalist:

$datalist = Catalog::get(0, $this->_catalog);(父id为0的，说明是所有）

3.catalog模型里面的函数：

    /**
     * 取分类
     */
	static public function get($parentid = 0, $array = array(), $level = 0, $add = 2, $repeat = '-') {
        
        $str_repeat = '';
        if ($level) {
            for($j = 0; $j < $level; $j ++) {
                $str_repeat .= $repeat;
            }
        }
        $newarray = array ();
        $temparray = array ();
        foreach ( ( array ) $array as $v ) {
            if ($v ['parent_id'] == $parentid) {
                $newarray [] = array ('id' => $v ['id'], 'catalog_name' => $v ['catalog_name'],
				'catalog_name_alias' => $v ['catalog_name_alias'],
				'parent_id' => $v ['parent_id'], 'level' => $level, 'sort_order' => $v ['sort_order'], 
				'seo_keywords' => $v ['seo_keywords'], 'seo_description' => $v ['seo_description'], 
				'attach_file' => $v ['attach_file'], 'attach_thumb' => $v ['attach_thumb'], 
				'status_is' => $v ['status_is'], 'data_count' => $v ['data_count'] , 
				'display_type' => $v ['display_type'], 'menu_is' => $v ['menu_is'],
				'template_list' => $v ['template_list'],'acl_browser' => $v ['acl_browser'],
				'acl_operate' => $v ['acl_operate'],'template_page' => $v ['template_page'],
				'template_show' => $v ['template_show'],'create_time' => $v ['create_time'],
				'str_repeat' => $str_repeat, 'page_size'=>$v['page_size'] );
    
                $temparray = self::get ( $v ['id'], $array, ($level + $add) );
                if ($temparray) {
                    $newarray = array_merge ( $newarray, $temparray );
                }
            }
        }
        return $newarray;
    }
