修改数据:

跳转到一个修改页面:

public function modify(){
$id=$_GET['id'];
$m=M('user');
$arr=$m->find($id);

将值传递给前台模板
<table border='1' width='500' align='center'>

</tr>
<volist name='data' id='vo'>

</tr>
</volist>

删除方法 把值传递给http://localhost:8080/thinkphp/index.php/User/del/id/<{$vo.id}>
public function del(){
$m=M('user');
$id=$_GET['id'];
$count=$m->delete($id);
echo $count;
if ($count >0){
$this->success('数据删除成功');
}else{
$this->error('数据删除失败');

把值传递给方法modify，
public function modify(){
$id=$_GET['id'];
$m=M('user');
$arr=$m->find($id);
$this->assign('data',$arr);
$this->display();
}
在把值分配到前台页面
