[英]Why does my CAPTCHA code fail?
I created a captcha for a contact form. 我为联系表格创建了一个验证码。 Everything works fine but whatever the number I enter into the captcha form it always shows invalid captcha
一切正常,但是无论我输入验证码表格中的数字是多少,它始终显示无效的验证码
<?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';
}
}
}
?>
can any one say what the solution is? 谁能说出解决方案是什么?
How are you storing $_SESSION['randomnr2'] ? 您如何存储$ _SESSION ['randomnr2']? Are you md5()'ing it?
你在用md5()吗?
Might help to see all the code. 可能会帮助您查看所有代码。
