基本電子郵件表格（php）

Question

我正在嘗試使用PHP從表單發送基本電子郵件。 表單使用jquery.validate.js進行了驗證（工作正常），但是我無法發送電子郵件。 我只是不斷獲取提交時在操作中聲明的php文件。

該站點位於此處 ，表單如下所示：

    <form method="post" action="send-email.php" id="contact-form" class="form-horizontal" role="form">
      <fieldset> 

        <div class="col-12  col-md-6  col-lg-6  contact--left">
          <div class="form-group">
            <label for="name" class="col-12  control-label  brand  brand-font">Name</label>
            <div class="col-12">
              <input type="text" class="form-control  brand-font--standard" name="name" id="name">
            </div>
          </div>                  
          <div class="form-group">
            <label for="email" class="col-12  control-label  brand  brand-font">Email</label>
            <div class="col-12">
              <input type="email" class="form-control  brand-font--standard" name="email" id="email">
            </div>
          </div>
          <div class="form-group">
            <label for="phone" class="col-12  control-label  brand  brand-font">Telephone</label>
            <div class="col-12">
              <input type="tel" class="form-control  brand-font--standard" name="phone" id="phone">
            </div>
          </div>
        </div>

        <div class="col-12  col-md-offset-1  col-md-5  col-lg-offset-1  col-lg-5  contact--right">
          <div class="form-group">
            <label for="message" class="col-12  control-label  brand  brand-font">Message</label>
            <div class="col-12">
              <textarea class="form-control  brand-font--standard" rows="6" name="message" id="message"></textarea>
            </div>
          </div>
          <div class="form-group">
            <div class="col-12">&nbsp;</div>
            <div class="col-12">
              <button type="submit" class="btn  btn-block  btn--orange  brand-font">Submit</button>
            </div>
          </div>
        </div>

      </fieldset>
    </form>

...，而send-email.php文件如下所示：

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

    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "contact@designbydarren.com";
    $email_subject = "Your email subject line";


    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($_POST['phone']) ||
        !isset($_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
    $phone = $_POST['phone']; // required
    $message = $_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)) {
    $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)) {
    $error_message .= 'The name you entered does not appear to be valid.<br />';
  }
  if(strlen($message) < 2) {
    $error_message .= 'The message you entered do not appear to be valid.<br />';
  }
  if(strlen($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";
    $email_message .= "Telephone: ".clean_string($phone)."\n";
    $email_message .= "Message: ".clean_string($message)."\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 -->

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

}

我試過使用其他一些我在網絡上找到的示例，但還沒有任何內容。 為菜鳥式的問題而道歉，但我更像是一個前鋒，所以對此類型的東西一無所知（但是，對於你們來說，這似乎很基本）

謝謝你的時間！

Answer 1

您必須在send-email.php的以下行中更改參數

if(!preg_match($email_exp,$email_from)){

因為您已經在$ email_from中提取了$ _POST ['email']

並且在使用默認的PHP郵件功能時，更改php.ini文件中的SMTP設置

希望能幫助到你！！！

Answer 2

您已按照以下步驟定義了訪問者的電子郵件地址：

$email_from = $_POST['email']; // required

但在第33行中，您嘗試使用$email ，它是未定義的：

if(!preg_match($email_exp,$email)) {

更改為：

if(!preg_match($email_exp,$email_from)) {

那應該可以解決問題，並且您的表格也可以工作。

不相關的旁注：PHP的mail()函數是一個錯誤的選擇。 我建議切換到PHPMailer或SwiftMailer，因為它們可以為您提供更好的控制並且更強大。
