?>

这种改如何添加各种操作啊,while循环中的话可以添加,foreach如何添加

回复讨论(解决方案)

输出条目时上去不就行了?

怎么做啊,我刚学,while

while($arr = mysql_fetch_array($res)){?><tr><td ><a href="?ac=edit&type_id=<?php echo $arr['type_id'];?>">编辑</a>      <a href="?ac=del&type_id=<?php  echo $arr['type_id'];?>">删除</a></td></tr>

输出时怎么加?

你上面不是已经加了么?

那个是错误的啊,程序中用的是foreach循环,而不是while啊,while我也会

foreach($arr as $value){
echo "";
echo "
";
}
?>

foreach($arr as $value){
echo "
";
echo "
";
}
?>
上面那个打错了。
如果你assoc 出来是只有ID就直接加$value 否则,你应该知道如何做

//真正的效果是这样的,做一个无限级分类,采用递归调用的方法,这里的

  • 之间无法加入链接啊

    echo " 

  • $k $v     热门群组ddd     编辑    删除 
  • " ;
    双引号中的双引号要转义!
    echo "
