Question

我很困惑。...

我创建了一个PHP表单来收集一些用户信息，并通过电子邮件将其发送给网站所有者，在表单提交后，这些字段会自动完成，并带有一个“ 1”。我假设这意味着该字段为真并已提交。 / p>

有人在提交表单后如何隐藏或删除1方面有任何建议吗？我只希望表单提交后为空白。这是代码，对不起格式不好和令人眼花wall乱的代码。

在此先感谢您的帮助！

PHP代码

    $errName = "";
    $errcatBreed = "";
    $errEmail = "";
    $errMessage = "";
    $result = "";

if (isset($_POST['submit'])) {
    $name = $_POST['name'];
    $catBreed = $_POST['catBreed'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $from = 'PearTreeHill Contact Form';
    $to = 'test@domain.com';
    $subject = "New furbaby enquiry from $name";

    $body ="From: $name\n Cat Breed: $catBreed\n E-Mail: $email\n Message:\n $message";

    // Check if name has been entered
    if (!$_POST['name']) {
        $errName = 'Please enter your name';
    }

    // Check if cat breed has been entered
    if (!$_POST['catBreed']) {
        $errcatBreed = 'Please enter either Ragdoll or British ShortHair';
    }

    // Check if email has been entered and is valid
    if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
        $errEmail = 'Please enter a valid email address';
    }

    //Check if message has been entered
    if (!$_POST['message']) {
        $errMessage = 'Please enter your message';
    }

    // RECAPTCHA
    if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response']))
  {
        $secret = 'Private Key';
        $verifyResponse = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST['g-recaptcha-response']);
        $responseData = json_decode($verifyResponse);
        if($responseData->success)
        {
            $succMsg = 'Your contact request have submitted successfully.';
        }
        else
        {
            $errMsg = 'Robot verification failed, please try again.';
        }
   }

// If there are no errors, send the email
if (!$errName && !$errcatBreed && !$errEmail && !$errMessage) {
    if (mail ($to, $subject, $body, $from)) {
        $result='<div class="alert alert-success">Thank You! I will be in touch</div>';
    } else {
        $result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again.</div>';
    }
}
    }

Answer 1

<?php echo htmlspecialchars(isset($_POST['email'])); ?>

此处显示isset()（TRUE或FALSE）的结果。

您应该这样做：

<?php if ( isset($_POST['email']) ) echo htmlspecialchars($_POST['email']); ?>

每个字段都有这个：-）

Answer 2

更改

echo htmlspecialchars（isset（$ _ POST ['name']））;

到

echo htmlspecialchars（$ _POST ['name']）

我的意思是删除isset（）;

PHP表单在提交后用一个填充
