初学php，为什么上面无法把name和password传到secret.php里，导致每次都输出Please input an effective username and password？
//secret.php
//Create short names for variables
if($_POST['name']==''&&$_POST['password']=='')
{
//Visitor need to enter a name and password
echo '
Please input an effective username and password
';}
elseif($_POST['name']=='root'&&$_POST['password']=='123')
{
echo '
Welcome to the New World!
';}
else
{
echo '
You are not welcome!
';}
?>
------解决方案--------------------
需要为input控件增加name属性，只有这样，浏览器才会把值提交到服务器
