聯系表格mailer.php返回空白頁

Question

在我嘗試添加reCAPTCHA之前，聯系表單工作正常。 我設法使reCAPTCHA出現，並帶有recaptchalib和mailer.php，后者是顯示空白頁面的頁面。 有什么想法我做錯了嗎？

這是mailer.php

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

    // check reCAPTCHA information
    require_once('recaptchalib.php');

    $privatekey = "privatekey";
    $resp = recaptcha_check_answer ($privatekey,
                                $_SERVER["REMOTE_ADDR"],
                                $_POST["recaptcha_challenge_field"],
                                $_POST["recaptcha_response_field"]);

    // if CAPTCHA is correctly entered!                        
    if ($resp->is_valid) {
        // great success!    
        $myemail = "operations@socialmarketing.com";

        /* Check all form inputs using check_input function */
        $name = $_POST['inputName'];
        $email = $_POST['inputEmail'];
        $subject = $_POST['inputSubject'];
        $message = $_POST['inputMessage'];

        /* Let's prepare the message for the e-mail */

        $subject = "Message From LGBT campaign Contact Form";

        $message = "

        China LGBT Contact Form

        Name: $name
        Email: $email

        Message:
        $message

        ";

        /* Send the message using mail() function */
        mail($myemail, $subject, $message);

        /* Redirect visitor to the thank you page */
        header('Location: successPage.html#contact');

    } else {
       // alert the captcha is not correct

    }
}?>

這是我的HTML頁面，我將其制作為.php頁面

<div class="marketing">
<div class="intro" id="contact">
  <h1>Contact Us</h1>
  <p>If you would like to stay informed about our progress or would like to help with the campaign, please fill out this form to send us an email.</p>
  <div class="panel-body">

        <div class="col-lg-10">
          <input type="text" class="form-control" name="inputName" placeholder="Your Name">
        </div>
      </div>
      <div class="form-group">
        <label class="col-lg-2 control-label">Email</label>
        <div class="col-lg-10">

        </div>
      </div>
      <div class="form-group">
        <label class="col-lg-2 control-label">Message</label>
        <div class="col-lg-10">
          <textarea class="form-control" rows="4" name="inputMessage" placeholder="Your message..."></textarea>
        </div>
      </div>

      <div class="form-group">
        <div class="col-lg-10 col-lg-offset-2">
        <p>Prove you are not a spambot</p>
        <?php require_once('recaptchalib.php');
            $publickey = "publickey";
            echo recaptcha_get_html($publickey);
          ?>

    </div>
  </div>

      <div class="form-group">
        <div class="col-lg-offset-2 col-lg-10">
          <button type="submit" class="btn btn-primary">Send Message</button>
        </div>
      </div>
    </form>
  </div>
</div>

任何與此有關的幫助將非常感謝。

謝謝一大堆

Answer 1

將您的按鈕更改為此：

<input type="submit" class="btn btn-primary" value="Send Message" name="submit">

POST正在尋找稱為命名屬性submit 。

它基於您的條件語句，因此不會在其中執行任何操作：

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

您也沒有命名表單元素和$subject = $_POST['inputSubject'];

要么添加一個：

Subject:<input type="text" class="form-control" name="inputSubject" placeholder="Subject">

或簡單地測試：

$subject = "Form submitted";

您應該確保所有字段都已填寫。 如果主題為空或其他任何主題，則可能不會因此而收到郵件，尤其是“電子郵件”字段。

另一個原因可能是因為您沒有適當的標題，包括From:

通過郵件訪問PHP.net網站：

• http://php.net/manual/en/function.mail.php

例如From:從網站標題：

$headers = 'From: webmaster@example.com' . "\r\n" .
    'Reply-To: webmaster@example.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

並修改mail($myemail, $subject, $message);
mail($myemail, $subject, $message, $headers);

引用它們：

注意：

發送郵件時，郵件必須包含“發件人”標頭。 可以使用Additional_headers參數設置此參數，也可以在php.ini中設置默認值。

未能執行此操作將導致類似警告的錯誤消息：php.ini中未設置mail（）：“ sendmail_from”或自定義“ From：”標頭丟失。 Windows下的From標頭還設置了Return-Path。

---

將錯誤報告添加到文件頂部，這將有助於發現錯誤。

<?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);

// rest of your code

旁注：錯誤報告僅應在登台進行，而不應在生產過程中進行。

Answer 2

如果頁面空白，那是因為某些東西出現故障並且沒有顯示錯誤。 首先，請確保在您的PHP腳本中啟用了錯誤報告。 將此添加到mailer.php的頂部。

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

您還需要在此處添加某種消息。

} else {

    // alert the captcha is not correct
    echo "captcha did not match!";
    exit;

}

同樣如前所述，請檢查您的錯誤日志。

Answer 3

您可以通過更改開始

<button type="submit" class="btn btn-primary">Send Message</button>

至

<input type="submit" class="btn btn-primary" value="submit">

這應該將您的表單提交到mailer.php。 從這一點來看，它應該起作用。
