代碼如下:
public $cateListAll = array();
public function editCate()
{
$this->cateChildList(0,$nb); // 從父級=0開始遞歸
$this->cateList=$this->cateListAll;
$this->display();
}
// 無限極分類
protected function cateChildList($pid,$nb)
{
$cate=M('cate');
$parent=$cate->where('parent_id="'.$pid.'"')->order('sort asc,id desc')->select();
if($parent)
{
$nb = $nb." ";
foreach($parent as $item)
{
$item['name']=$nb.'├ '.$item['name'];
$this->cateListAll[]=$item;
$this->cateChildList($item['id'],$nb);
}
}
}其中前台html直接循環cateList即可
