具体代码如下:
<div class="jb51code">
<pre class="brush:php;">
/**
- 无级递归分类
- @param int $assortPid 要查询分类的父级id
- @param mixed $tag 上下级分类之间的分隔符
- @return string $tree 返回的分类树型结构结果
-
*/
function recursiveAssort($assortPid,$tag = '')
{
$assort = M('goods_class')->where("class_pid = $assortPid")->field('class_id,class_name')->select();
foreach ($assort as $value) {
$tree .= '<option value="' . $value['class_id'] . '">' . $tag . $value['class_name'] . '';
$tree .= recursiveAssort($value['class_id'],$tag . ' ');
}
return $tree;
}
