Question

我有以下HTML：

<form method="post" action="https://www.domain.co.uk/v2/contact.php" id="contactform">
              <p><label for="name"><span class="required">*</span> Your Name</label><br>
              <input name="name" type="text" id="name" size="30" value="" class="input" required> </p>
              <p><label for="email"><span class="required">*</span> Email</label><br>
              <input name="email" type="email" id="email" size="30" value="" class="input" required></p>
              <p><label for="phone">Phone</label><br>
              <input name="phone" type="tel" id="phone" size="30" value="" class="input"></p>
              <p><label for="subject">Subject</label><br>
              <select name="subject" id="subject" class="input">
              <option value="Not sure" selected="selected">Not sure</option>
                <option value="this">this</option>
                <option value="that">that</option>
              </select></p>              
              <p><label for="comments"><span class="required">*</span> Message</label><br>
              <textarea name="comments" cols="40" rows="3" id="comments" class="input" required></textarea></p>
              <p><input type="submit" class="submit" id="submit" value="Submit"></p>
              </form>

以及以下contact.php中的内容

<?php

    if ($_POST['name'] != "") {
    $_POST['name'] = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
    if ($_POST['name'] == "") {
        $errors .= 'Please enter a valid name.<br/><br/>';
    }
    } else {
        $errors .= 'Please enter your name.<br/>';
    }

    if ($_POST['email'] != "") {
    $email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        $errors .= "$email is <strong>NOT</strong> a valid email address.<br/><br/>";
    }
    } else {
        $errors .= 'Please enter your email address.<br/>';
    }

    if ($_POST['phone'] != "") {
    $_POST['phone'] = filter_var($_POST['phone'], FILTER_SANITIZE_STRING);
    if ($_POST['phone'] == "") {
        $errors .= 'Please enter your phone number.<br/>';
    }
    } else {
        $errors .= 'Please enter your phone number.<br/>';
    }

    if ($_POST['subject'] != "") {
    $_POST['subject'] = filter_var($_POST['subject'], FILTER_SANITIZE_STRING);
    if ($_POST['subject'] == "") {
        $errors .= 'Please choose a subject.<br/>';
    }
    } else {
        $errors .= 'Please choose a subject.<br/>';
    }

    if ($_POST['comments'] != "") {
    $_POST['comments'] = filter_var($_POST['comments'], FILTER_SANITIZE_STRING);
    if ($_POST['comments'] == "") {
        $errors .= 'Please enter a message.<br/>';
    }
    } else {
        $errors .= 'Please enter a message.<br/>';
    }


    if (!$errors) {
            $mail_to = 'info@myemails.co.uk';
            $subject = 'Enquiry';
            $message .= 'Regarding: ' . $_POST['subject'] . "\n\n";
            $message .= 'Name: ' . $_POST['name'] . "\n\n";
            $message .= 'Email: ' . $_POST['email'] . "\n\n";
            $message .= 'Phone: ' . $_POST['phone'] . "\n\n";
            $message .= 'Message ' . $_POST['comments'] . "\n\n";

            $success = mail($mail_to, $subject, $message, "From: <$email>");

            if ($success){
              print "sent";
            }
            else{
              print "failed";
            }
    }

?>

无论我进行了什么更改或尝试，我最终都在contact.php的空白页面上看到了已发送或失败的消息（已删除我的javascript验证，以防我在其中引起问题），同样地，错误日志，尽管返回了代码，但我找不到问题？不确定我盯着它看了太久而错过了明显的东西还是有更深层次的问题？

任何指针表示赞赏。

var_dump显示它正在获取信息：

array(5) { ["name"]=> string(10) "Joe Bloggs" ["email"]=> string(16) "joe@anyemail.com" ["phone"]=> string(11) "07123456789" ["subject"]=> string(8) "Not sure" ["comments"]=> string(17) "test message here" }

您使用了字符串连接，但是在此之前您没有定义变量，如果您更改代码，就像这样：

<?php

        $errors = '';

        if ($_POST['name'] != "") {
        $_POST['name'] = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
        if ($_POST['name'] == "") {
                $errors .= 'Please enter a valid name.<br/><br/>';
        }
        } else {
                $errors .= 'Please enter your name.<br/>';
        }

        if ($_POST['email'] != "") {
        $email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);
        if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
                $errors .= "$email is <strong>NOT</strong> a valid email address.<br/><br/>";
        }
        } else {
                $errors .= 'Please enter your email address.<br/>';
        }

        if ($_POST['phone'] != "") {
        $_POST['phone'] = filter_var($_POST['phone'], FILTER_SANITIZE_STRING);
        if ($_POST['phone'] == "") {
                $errors .= 'Please enter your phone number.<br/>';
        }
        } else {
                $errors .= 'Please enter your phone number.<br/>';
        }

        if ($_POST['subject'] != "") {
        $_POST['subject'] = filter_var($_POST['subject'], FILTER_SANITIZE_STRING);
        if ($_POST['subject'] == "") {
                $errors .= 'Please choose a subject.<br/>';
        }
        } else {
                $errors .= 'Please choose a subject.<br/>';
        }

        if ($_POST['comments'] != "") {
        $_POST['comments'] = filter_var($_POST['comments'], FILTER_SANITIZE_STRING);
        if ($_POST['comments'] == "") {
                $errors .= 'Please enter a message.<br/>';
        }
        } else {
                $errors .= 'Please enter a message.<br/>';
        }

        $message = '';
        if (empty($errors)) {
                        $mail_to = 'info@myemails.co.uk';
                        $subject = 'Enquiry';
                        $message .= 'Regarding: ' . $_POST['subject'] . "\n\n";
                        $message .= 'Name: ' . $_POST['name'] . "\n\n";
                        $message .= 'Email: ' . $_POST['email'] . "\n\n";
                        $message .= 'Phone: ' . $_POST['phone'] . "\n\n";
                        $message .= 'Message ' . $_POST['comments'] . "\n\n";

                        $success = mail($mail_to, $subject, $message, "From: <$email>");

                        if ($success){
                            print "sent";
                        }
                        else{
                            print "failed";
                        }
        } else {
            echo $errors;
        }

?>

它有效。您说您在现场，所以如果您愿意，可以添加以下几行：

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

在您的php文件顶部的

可以看到错误，但是客户端也可以看到这些错误。您可以为它们周围的IP添加IP Check。
