表单在网站中的应用可以说是网站的根基,几乎没有不用表单的网站,还是先回顾一下表单的用法吧


  文本框的用法:
  
  其中input类型包括text、password等类型,HTML5新增了很多的input类型,如果想学习这类的知识可以很好的了解一下,因为分的越细,用的越方便。
  
  看看本实例的功能

  填入表单提交后:


实现代码:
代码如下:
















管理员:
密 码:

if(!isset($_POST['submit']))
return ;
if($_POST['submit']=='submit'){
$username = $_POST['username'];
$password = $_POST['password'];
}
echo






管理员:$username
密码:$password

EOT;
?>

使用 isset()函数判断$_POST['submit']是否被设置
