PHP表单未成功提交获取自定义错误

Question

我的 PHP 表单没有成功提交。我不断收到我写的自定义错误（“糟糕，出现问题。请重试”）。

任何帮助将不胜感激。我对 PHP 完全陌生，所以我想也许我的一些 php 变量链接错误并且没有连接到我的 mailer-new.php 文件？

提前致谢，

   <section class="form-body">
    <form method="post" action="mailer-new.php" class="contact-form" >
        <div class="row">
            <?php
                if ($_GET['success']== 1){
                    echo " <div class=\"form-messages success\"> Thank you! 
                your message has been sent. </div>";
                }
                if ($_GET['success']== -1){
                    echo " <div class=\"form-messages error\"> Opps there was a 
                  problem. Please try again </div>";
                };
                ?>
            <div class="field name-box">
                <input type="text" name="name" id="name" placeholder="Who 
                    Are You?" required/>
                <label for="name">Name</label>
                <span class="ss-icon">check</span>
            </div>
            <div class="field email-box">
                <input type="text"  name="email" id="email" 
                    placeholder="name@email.com" required/>
                <label for="email">Email</label>
                <span class="ss-icon">check</span>
            </div>
            <div class="field msg-box">
                <textarea name="message" id="msg" rows="4" 
                    placeholder="Your message goes here..."/></textarea>
                <label for="message">Msg</label>
                <span class="ss-icon">check</span>
            </div>
            <input class="button" type="submit" value="Send"/>
        </div>
    </form>
</section>

MAILER.PHP

<?php

// Get the form fields, removes html tags and whitespace.
$name    = strip_tags(trim($_POST["name"]));
$name    = str_replace(array("\r","\n"), array(" ", " " ), $name);
$email   = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
$message = trim($_POST["message"]);

// Check the data.
if (empty($name) OR empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) {
    header("Location: http://www.conallen.ie/index.php?
 success=-1#form");
    exit;
}

// Set the recipient email address. Update this to YOUR desired email address.
$recipient = "allenconallen46@gmail.com";

// Set the email subject.
$subject = "New contact from $name";

// Build the email content.
$email_content = "Name: $name\n";
$email_content .= "Email: $email\n\n";
$email_content .= "Message:\n$message\n";

// Build the email headers.
$email_headers = "From: $name <$email>";

// Send the email.
mail($recipient, $subject, $email_content, $email_headers);

// Redirect to the index.html page with success code
header("Location: http://www.conallen.ie/index.php?success=1#form");

?>

此代码在我的本地计算机上正常工作，即使未发送电子邮件，响应消息也正确发送。我所做的更改是更改主机名并将两行标题重定向到失败响应中的一行。您还在 HTML 中提到了文件名action="mailer-new.php"，问题中提到的文件名是MAILER.PHP。它们在代码中是否相同？

要检查邮件是否已发送，请删除标头重定向并像这样更新。如果您收到失败的响应，则表示您的服务器中未配置邮件。

if(mail($recipient, $subject, $email_content, $email_headers)) {
echo "mail sent";
} else {
 echo "mail sent failed";
}

您也可以使用 SMTP 发送电子邮件。您可以使用一个名为 PHP Mailer 的库，并且可以使用任何有效的电子邮件地址，例如 gmail 帐户。如果是这种情况，请看看这个问题
