我试图包含一个文件，该文件生成2个需要添加的随机数，或者我们称之为captcha。我有两个登录：一个需要员工id、出生日期和captcha答案（我称之为简单登录）。而另一个需要你的名字、姓氏、出生日期和captcha（我称之为标准登录）。因此，我有两个单选按钮供用户选择是简单登录还是标准登录。所以我遇到了这个问题，当你选择登录时，你需要回答captcha（captcha发送会话来获取答案），所以现在发生的事情是，简单登录中的captcha总是被标准登录中的captcha覆盖。我想我会做的是设置一个条件，如果选择了单选按钮（轻松登录），那么这就是它将被包括在内的时间。但我不知道该怎么做。
这是captcha代码：captcha.php
<?php
session_start();
$n1=rand(1,6); //Generate First number between 1 and 6
$n2=rand(5,9); //Generate Second number between 5 and 9
$answer=$n1+$n2;
$math = "What is ".$n1." + ".$n2." ? ";
$_SESSION['vercode'] = $answer;
print $math;
?>
下面是我的界面代码：
index.php
<SCRIPT TYPE="text/javascript">
function toggleTables(which)
{
if(which == "0") {
document.getElementById('standard').style.display = "table";
document.getElementById('customize').style.display = "none";
}
if(which == "1") {
document.getElementById('customize').style.display = "table";
document.getElementById('standard').style.display = "none";
}
}
</SCRIPT>

将文件的第一行设置为
<?php include_once ('../include/mathcaptcha.php'); ?>
然后更改的线路
<td>
<?php
include ('../include/mathcaptcha.php');
?>
</td>
至
<td><?php echo $math;?></td>
并从captcha文件中取出打印件。PHP不会影响页面的设计，只会影响输出的数据，这些数据应该根据需要进行更改。
