为什么我的验证码失败？
我为联系表单创建了验证码。一切正常，但无论我在验证码表单中输入多少数字，它总是显示无效的验证码，
<?php
if(isset($_POST['norobot']))
{
if(md5($_POST['norobot']) == $_SESSION['randomnr2'])
{
echo "Validation Success";
$_SESSION['name'] = $name ;
$_SESSION['phone_no'] = $phone;
$_SESSION['mailid'] = $mailid;
$_SESSION['msg'] = $msg;
$_SESSION['category'] = $category;
header("Location:thankyou.php");
}
else
{
$Error = 'Invalid CAPTCHA';
}
}
}
?>
有人能说出解决方案是什么吗？
I created a captcha for a contact form. Everything works fine but whatever the number I enter into the captcha form it always shows invalid captcha
<?php
if(isset($_POST['norobot']))
{
if(md5($_POST['norobot']) == $_SESSION['randomnr2'])
{
echo "Validation Success";
$_SESSION['name'] = $name ;
$_SESSION['phone_no'] = $phone;
$_SESSION['mailid'] = $mailid;
$_SESSION['msg'] = $msg;
$_SESSION['category'] = $category;
header("Location:thankyou.php");
}
else
{
$Error = 'Invalid CAPTCHA';
}
}
}
?>
can any one say what the solution is?

您如何存储 $_SESSION['randomnr2'] ？你是 md5() 吗？
可能有助于查看所有代码。
How are you storing $_SESSION['randomnr2'] ? Are you md5()'ing it?
Might help to see all the code.
