無法加載“PHP電子郵件表單”庫

大家好，由于某種原因，我的 PHP 表單無法正常作業，當有人按下發送訊息按鈕時，此錯誤會彈出“無法加載“PHP 電子郵件表單”庫”。我不知道有什么問題。你能幫助我嗎 ？:)

這是contact.php

<?php

    $receiving_email_address = 'myemailadress';
    
      if( file_exists($php_email_form = '../assets/vendor/php-email-form/php-email-form.php' )) {
        include( $php_email_form );
      } else {
        die( 'Coming Soon!');
      }
    
      $contact = new PHP_Email_Form;
      $contact->ajax = true;
      
      $contact->to = $receiving_email_address;
      $contact->from_name = $_POST['name'];
      $contact->from_email = $_POST['email'];
      $contact->subject = $_POST['subject'];
    
      // Uncomment below code if you want to use SMTP to send emails. You need to enter your correct SMTP credentials
      /*
      $contact->smtp = array(
        'host' => 'example.com',
        'username' => 'example',
        'password' => 'pass',
        'port' => '587'
      );
      */
    
      $contact->add_message( $_POST['name'], 'From');
      $contact->add_message( $_POST['email'], 'Email');
      $contact->add_message( $_POST['message'], 'Message', 10);
    
      echo $contact->send();
    ?>

這是 index.html

 <div class="form">
              <form action="forms/contact.php" method="post" role="form" class="php-email-form">
                <div class="row">
                  <div class="form-group col-md-6">
                    <input type="text" name="name" class="form-control" id="name" placeholder="Your Name" required>
                  </div>
                  <div class="form-group col-md-6 mt-3 mt-md-0">
                    <input type="email" class="form-control" name="email" id="email" placeholder="Your Email" required>
                  </div>
                </div>
                <div class="form-group mt-3">
                  <input type="text" class="form-control" name="subject" id="subject" placeholder="Subject" required>
                </div>
                <div class="form-group mt-3">
                  <textarea class="form-control" name="message" rows="5" placeholder="Message" required></textarea>
                </div>
                <div class="my-3">
                  <div class="loading">Loading</div>
                  <div class="error-message"></div>
                  <div class="sent-message">Your message has been sent. Thank you!</div>
                </div>
                <div class="text-center"><button type="submit">Send Message</button></div>
              </form>
            </div>

Anf 出于某種原因，檔案夾中出現了某種錯誤日志檔案，內容為：

[19-Nov-2021 13:49:31 UTC] PHP Fatal error:  Uncaught Error: Class 'PHP_Email_Form' not found in /home/domain/public_html/forms/contact.php:16
Stack trace:

  thrown in /home/domain/public_html/forms/contact.php on line 16
[19-Nov-2021 13:49:32 UTC] PHP Fatal error:  Uncaught Error: Class 'PHP_Email_Form' not found in /home/domain/public_html/forms/contact.php:16
Stack trace:
#0 {main}
  thrown in /home/domain/public_html/forms/contact.php on line 16

我想我應該在第 16 行添加這個 home/domain/public.html/froms/contact.php 但我顯然不知道如何正確添加。

你能幫我嗎 ？

uj5u.com熱心網友回復：

您不能在file_exists(). 用

if( file_exists('../assets/vendor/php-email-form/php-email-form.php')) {
    include('../assets/vendor/php-email-form/php-email-form.php');
} else {
    die( 'Coming Soon!');
}

或者

$php_email_form = '../assets/vendor/php-email-form/php-email-form.php';
if(file_exists($php_email_form)) {
    include($php_email_form);
} else {
    die('Coming Soon!');
}

uj5u.com熱心網友回復：

如果您從模板的免費版本下載這些代碼，那么它將無法作業。您需要一個 PHP 電子郵件表單庫。如果您檢查您的assets/vendor/php-email-form/，您將缺少 php-email-form.php 檔案。據我所知，您必須購買才能獲得該檔案。
