thinkPHP实现递归循环栏目并按照树形结构无限极输出的方法,thinkphp递归
本文实例讲述了thinkPHP实现递归循环栏目并按照树形结构无限极输出的方法。分享给大家供大家参考,具体如下:
这里使用thinkphp递归循环栏目按照树形结构无限极输出,并保存为一个数组,利于模板调用
具体代码如下:
private function categoryTree($parentid,$level) //因为是本类中使用所以定于为私有函数 { $Category= D('Category'); $result = $Category->where("`parentid`=".$parentid)->order("listorder desc,catid desc")->select(); if($result) { $count=count($result);//当前子栏目个数 $level++;//子栏目层级 foreach($result as $v) { $index++; if($count==$index) $step="└─"; else $step="├─"; $step.=str_repeat(' ',$level-1); $nbsp=str_repeat(' ',$level-1); $nstr=$nbsp.$step; if($parentid==0) $nstr=''; $v['step']=$nstr; $newData[$v['catid']]=$v; //echo $nstr.$v['catname']."<br />"; if($v['child']==1)//如果有子栏目 { $newData=$newData+$this->categoryTree($v['catid'],$level); } } } return $newData; }
php递归栏目保存为数组
