Question

我正在为网站创建一个电子邮件表单，html代码如下。

        <form class="form" name="htmlform" method="post" action="contact_process.php">
        <table width="450px">
        </tr>
        <tr>
         <td valign="top">
          <label for="first_name">First Name *</label>
         </td>
         <td valign="top">
          <input  type="text" name="first_name" maxlength="50" size="30">
         </td>
        </tr>

        <tr>
         <td valign="top"">
          <label for="last_name">Last Name *</label>
         </td>
         <td valign="top">
          <input  type="text" name="last_name" maxlength="50" size="30">
         </td>
        </tr>
        <tr>
         <td valign="top">
          <label for="email">Email Address *</label>
         </td>
         <td valign="top">
          <input  type="text" name="email" maxlength="80" size="30">
         </td>

        </tr>
        <tr>
         <td valign="top">
          <label for="telephone">Telephone Number</label>
         </td>
         <td valign="top">
          <input  type="text" name="telephone" maxlength="30" size="30">
         </td>
        </tr>
        <tr>
         <td valign="top">
          <label for="comments">Comments *</label>
         </td>
         <td valign="top">
          <textarea  name="comments" maxlength="1000" cols="25" rows="6"></textarea>
         </td>

        </tr>
        <tr>
         <td colspan="2" style="text-align:center">
          <input type="submit" value="Submit">
         </td>
        </tr>
        </table>
        </form>
        <p>* Mandatory fields</p>

尝试了很多PHP代码（在contact_process.php中），但没有通过电子邮件将表单发送到指定的电子邮件。

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

    $email_to = "johmwe@outlook.coM";

    $email_subject = "Feedback Form Submissions";


    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($_POST['first_name']) ||
        !isset($_POST['last_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.');       
    }

    $first_name = $_POST['first_name']; // required
    $last_name = $_POST['last_name']; // required
    $email_from = $_POST['email']; // required
    $telephone = $_POST['telephone']; // not required
    $comments = $_POST['comments']; // 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($string_exp,$first_name)) {
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
  }
  if(!preg_match($string_exp,$last_name)) {
    $error_message .= 'The Last Name you entered does not appear to be valid.<br />';
  }
  if(strlen($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);
    }

    $email_message .= "First Name: ".clean_string($first_name)."\n";
    $email_message .= "Last Name: ".clean_string($last_name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Comments: ".clean_string($comments)."\n";


// creating 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);  
?>

Thank you for contacting us. We will be in touch with you very soon.

<?php
}
die();
?>

有人可以查看代码以及我做错了什么。

此外，我想包括对发件人的自动回复和可能出现安全问题的CAPTCHA图片。

如果您检查邮件是否发送，这很方便。这由以下

进行

if (mail ($email_to, $email_subject, $email_message, $headers)) {
    echo "mail send";
} else {
    echo "failure to send";
}

它在if else语句中运行mail函数，如果您看到是否有错误，则会生成。如果是这样，你必须调试以找出错误是什么，因为那里有几个变量。它可能只是变量中的格式问题。

修改

另外，也许这就是我，但这在我的代码中对我没有意义。

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

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

$email_message .= "First Name: ".clean_string($first_name)."\n";
$email_message .= "Last Name: ".clean_string($last_name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "Telephone: ".clean_string($telephone)."\n";
$email_message .= "Comments: ".clean_string($comments)."\n";

为什么你要检查你的字符串是否有内容类型，盲目抄送等的其他标签......并且无需替换它。我的意思是......为什么要首先添加它，你甚至在哪里添加到你的内容。我不明白，是吗？

这很糟糕，甚至可能因为我试图在评论中放置复制代码的锚点，这将自动删除，因为您不会允许href属性。如果我是一名看到代码中的错误并希望指向您并将代码复制过来的客户，该怎么办？这只是在思考btw和我的POV。

编辑2

我也希望你用这段代码if(isset($_POST['email'])) {来实现，你可以低音检查是否设置了电子邮件变量。因此，如果我只是填写一封电子邮件并运行它，整个脚本就会执行。你最好能在提交动作上做到这一点。你还没有为它设置名称，所以你可能想这样做。

<input type="submit" value="Submit"> - ＆gt; <input type="submit" name="SubmitEmail" value="Submit">

然后检查

if(isset($_POST['SubmitEmail'])) {

PHP电子邮件不起作用
