我的 php 网站电子邮件表单出现问题

Question

我有一个网站，我只想要一个联系表，该表将接受用户的评论，然后将电子邮件发送给我。我有以下 html 代码：

        <form action="emailform.php" method="post" name="contactform" role="form">
            <div class="row">
                <div class="col-md-5">
                    <div class="form-group left-inner-addon">
                        <span class="glyphicon glyphicon-user"></span>
                        <input name="name" type="text" class="form-control" placeholder="Name" required>
                    </div>
                    <div class="form-group left-inner-addon">
                        <span class="glyphicon glyphicon-envelope"></span>
                        <input name="email" type="email" class="form-control" placeholder="Email" required>
                    </div>
                    <div class="form-group left-inner-addon">
                        <span class="glyphicon glyphicon-earphone"></span>
                        <input name="telephone" type="tel" class="form-control" placeholder="Phone" required>
                    </div>
                </div> 
                <div class="col-md-7">
                    <div class="form-group left-inner-addon">
                        <span class="glyphicon glyphicon-comment"></span>
                        <textarea name="message" rows="6" class="form-control" placeholder="Message..."></textarea><br>
                        <a><button type="submit" class="btn btn-primary" value="Submit">Send</button></a>
                        <button type="reset" class="btn btn-default right">Reset</button>

                    </div>
                </div>
            </div> <!-- row -->
        </form>

我这里有 php 代码 "emailform.php"：

    <?php
    if(isset($_POST['submit'])) {

    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "george@lehaftech.com";
    $email_subject = "PILLAR 360 Inquiry";

    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }


    // validation expected data exists
    if(!isset($_POST['name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['telephone']) ||
        !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
    }



    $name = $_POST['input_name']; // required
    $email_from = $_POST['input_email']; // required
    $telephone = $_POST['input_tel']; // not required
    $comments = $_POST['message']; // required

    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';

    if(!preg_match($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }

    $string_exp = "/^[A-Za-z .'-]+$/";

      if(!preg_match($string_exp,$name)) {
    $error_message .= 'The name you entered does not appear to be valid.<br />';
  }

  if(strlen($comments) < 2) {
    $error_message .= 'The Comments you entered do not appear to be valid.<br />';
  }

  if(strlen($error_message) > 0) {
    died($error_message);
  }

    $email_message = "Form details below.\n\n";


    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }



    $email_message .= "Name: ".clean_string($name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Comments: ".clean_string($comments)."\n";

// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  
?>

<!-- include your own success html here -->

<?php

}
?>

当我使用联系表单发送电子邮件时，我只是加载了一个空白页面，但电子邮件没有发送...所以错误代码没有显示，成功行也没有显示..

提前致谢。

Answer 1

自从我查看 PHP 以来已经有一段时间了 - 所以这可能不是问题 - 但在你的表单中 - 你的提交按钮有一个 value="Submit" - 即：大写 - 但在你的php 页面 - 它正在寻找 "submit" 即 - 未大写：

if(isset($_POST['submit'])) {...

因此 php 页面中缺少错误处理块。

您需要更改 html 或 php 中的任意一个以确保两者相同

if(isset($_POST['Submit'])) {...

此外 - 您的表单输入名称似乎与您在 php 页面

中使用的 POST 值不匹配

$name = $_POST['input_name']; // required
$email_from = $_POST['input_email']; // required
$telephone = $_POST['input_tel']; // not required
$comments = $_POST['message']; // required

您只有"name"、"email"等形式的输入

$name = $_POST['name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$comments = $_POST['message']; // required

Answer 2

将以下代码行添加到您的 HTML 文件中，紧跟在表单标记之后：

<input type="hidden" name="action" value="send">

并在您的 PHP 文件中更改：

if(isset($_POST['submit'])) {...

到

if(isset($_POST['action']) && $_POST['action'] === 'send') {...

希望对您有所帮助。

Answer 3

需要为提交按钮添加名称

<button type="submit" name="submit" class="btn btn-primary" value="Submit">Send</button>

同时修改部分代码如下

// validation expected data exists
if(!isset($_POST['name']) ||
    !isset($_POST['email']) ||
    !isset($_POST['telephone']) ||
    !isset($_POST['message'])) {
    died('We are sorry, but there appears to be a problem with the form you submitted.');       
}


$name = $_POST['name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$comments = $_POST['message']; // required

希望这些更改可以解决您的代码问题。
