问题描述

代码如下:

if(isset($_REQUEST[session_name()]))
{
   session_start();
}
else
{
   header("Location: authorize.php");
}
if($_SESSION['usr_id'] == md5(crypt($_SESSION['login'],$_SESSION['pass'])))

当用户按下发送"按钮时，我想从表格中获取选中复选框的值.我该怎么做?

I want to get value of checked checkbox from table when user press on "send" button. How can I do that?

推荐答案

你应该为 HTML 代码中的复选框赋值

You should assign a value for checkbox in HTML code

Active: <input type='checkbox' name='Active' value='1'> 

然后如果复选框被选中，它包含在 POST 中分配的值，否则您必须在未选中复选框时进行设置

and then if the checkbox is checked it contains assigned value in POST otherwise you have to set when checkbox is unchecked

$active = isset($_POST['Active']) && $_POST['Active']  ? "1" : "0";
