验证码验证和发送电子邮件

Question

我在表单上验证和进一步处理验证码时遇到问题。我想确认答案是正确的，然后发出电子邮件，并将用户发送到感谢页面，否则将其带到错误页面，如果用户未能输入正确的回应验证码。我在表单的隐藏输入字段上捕获captcha代码。即使在输入正确的代码后，它仍然会将我重定向到我设置的error.html页面。

参见下面的代码我使用了'captcha_ code '，在这里我试图获得true/false的值。一旦答案是真或假，它将继续IF语句，要么发送一封电子邮件，要么将其带到谢谢页面。

(如果我没有发布任何代码，请务必让我知道我会立即发布该代码。)

PHP代码：(更新了下面的代码帖子注释)*即使验证码是正确的，仍然会被定向到错误页面。

    <?php
if ($_POST["submit"]) {
$companyName = $_POST['tscpCompanyName'];
$businessType = $_POST['tscpBusinessType'];
$yearsBusiness = $_POST['tscpYears'];
$numberOfUnits = $_POST['tscpNumberOfUnits'];
$firstName = $_POST['tscpFirstName'];
$lastName = $_POST['tscpLastName'];
$email = $_POST['tscpEmail'];
$number = $_POST['tscpNumber'];
$vals = $_POST['vals'];
$human = intval($_POST['captcha_code']);

$from = "From:test@from.com";
$to = "test@to.com";
$subject = 'Custom Package Request';

$body ="Company Name: $companyName\n\n Business Type: $businessType\n\n Years In Business: $yearsBusiness\n\n First Name: $firstName\n\n Last Name: $lastName\n\n Email: $email\n\n Number: $number\n\n Services: $vals\n\n";


if (!isset($_SESSION)) session_start();
if ($_POST['captcha_code'] == $_SESSION['code']) {
echo 'true';
} else {
echo 'false';
}

//Check if simple anti-bot test is correct
if ($human !== false) {
    $errHuman = 'Your anti-spam is incorrect';
}
// If there are no errors, send the email

if (!$errName && !$errEmail && !$errMessage && !$errHuman) {
    if (mail ($to, $subject, $body, $from)) {
        header("Location: /thank-you/mortgage-lending.html");
    } else {
        header("Location: /error.html");
    }
}
else {
    header("Location: /error.html");
}
}?>

Answer 1

您正在使用post发布表单。因此，对验证码使用$_POST，而不是$_GET

Answer 2

我已经想出了解决这个问题的办法。我首先更新了IF语句，该语句将邮寄出去，并将我重定向到正确的页面。我还确保更新了我的$POST & session_start()。

以下是PHP代码：

  <?php
  if (!isset($_SESSION)) session_start();

   if ($_POST["submit"]) 
   {
    $companyName        = $_POST['tscpCompanyName'];
    $businessType   = $_POST['tscpBusinessType'];
    $yearsBusiness  = $_POST['tscpYears'];
    $numberOfUnits  = $_POST['tscpNumberOfUnits'];
    $firstName          = $_POST['tscpFirstName'];
    $lastName           = $_POST['tscpLastName'];
    $email                  = $_POST['tscpEmail'];
    $number                 = $_POST['tscpNumber'];
    $vals                   = $_POST['vals'];
    $human                  = intval($_POST['captcha_code']);
    $captchaError= FALSE;

    $from = "From:test@from.com";
    $to = "test@test.com";
    $subject = 'Custom Package Request';

    $body ="Company Name: $companyName\n\n Business Type: $businessType\n\n Years In Business: $yearsBusiness\n\n First Name: $firstName\n\n Last Name: $lastName\n\n Email: $email\n\n Number: $number\n\n Services: $vals\n\n";

    if ($_POST['captcha_code'] != $_SESSION['code']) 
    {
    $captchaError = TRUE;
    $errHuman = 'Your anti-spam is incorrect';
    }

    if (!$errName && !$errEmail && !$errMessage && !$captchaError) {
    if (mail ($to, $subject, $body, $from)) {
    header("Location: /thank-you/mortgage-lending.html");
    } else {
    header("Location: /error.html");
    }
    }
    else {
header("Location: /error.html");
    }
    }?>
