PHP教程：thinkphp获取栏目和文章当前位置的方法

<a href="">首页</a> -> <a href="/cat_2.html">PHP学习</a> -> <a href="/cat_9.html">ecshop</a> -> <a href="/cat_13.html">ecshop二次开发</a> -> ecshop加入百度地图,支持周边标记

//当前位置-第一个参数 catid为当前栏目的id,第二个参数为文章的标题,调用栏目当前位置时第二个参数为空即可.
$this->assign("now_here",$this->now_here($catid,$res['title']));
 
//解释一下,栏目表category中的catid为栏目id,catname为栏目名称,asmenu为栏目父级的id,当为顶级栏目时,asmenu为0 .

PHP实例protected function now_here($catid,$ext=''){
 $cat = M("Category");
 $here = '<a href="">首页</a>';
 $uplevels = $cat->field("catid,catname,asmenu")->where("catid=$catid")->find();
 if($uplevels['asmenu'] != 0)
 $here .= $this->get_up_levels($uplevels['asmenu']);
 $here .= ' -> <a href="/cat_'.$uplevels['catid'].'.html">'.$uplevels['catname']."</a>";
 if($ext != '') $here .= ' -> '.$ext;
 return $here;
}
protected function get_up_levels($id){
 $cat = M("Category");
 $here = '';
 $uplevels = $cat->field("catid,catname,asmenu")->where("catid=$id")->find();
 $here .= ' -> <a href="/cat_'.$uplevels['catid'].'.html">'.$uplevels['catname']."</a>";
 if($uplevels['asmenu'] != 0){
  $here = $this->get_up_levels($uplevels['asmenu']).$here;
 }
 return $here;
}
