这款无限分类php 递归函数是一款php 与sql查询递归的方法,很简单就是查询一次当前分类没有没子类,如果有的话就再调用函数本身来操作,如果己经没有子类了就可以返回了。

这款无限分类php教程 递归函数是一款php 与sql查询递归的方法,很简单就是查询一次当前分类没有没子类,如果有的话就再调用函数本身来操作,如果己经没有子类了就可以返回了。

function createsortoptions ($selected=0,$parent_id=0,$n=-1)
{
global $db;
$sql = "select * from `@__article_sort` where `parent_id` = '{$parent_id}'";
$options = ";
static $i = 0;
if ($i == 0)
{
$options .= ' if ($row['sort_id'] == $selected)
{
$options .=' selected ';
}
$options .=">".str_repeat(' ',$n*3).$row['sort_name']."n";
$options .=createsortoptions ($selected,$row['sort_id'],$n);
}
}
return $options;
}

如果是用smarty模板的朋友可以如下调用

//– $tpl->assign('sort_list',createsortoptions ());
//– $tpl->assign('sort_list',createsortoptions ($sort_id));
