php - 发送电子邮件按钮

Question

我正在使用 HTML、CSS、jQuery 和 PHP 中的 Wordpress 编码开发一个网站，我需要创建一个包含以下信息的按钮:姓名、邮件和消息，当用户点击发送并填写此信息时，它将发送到电子邮件，我的问题是如何使按钮工作，我正在实时网站上对其进行测试。另外，我在哪里定义接收所有信息的电子邮件。

    <?php

  //response generation function

  $response = "";

  //function to generate response
  function my_contact_form_generate_response($type, $message){

    global $response;

    if($type == "success") $response = "<div class='success'>{$message}</div>";
    else $response = "<div class='error'>{$message}</div>";

  }

  //response messages
  $not_human       = "Human verification incorrect.";
  $missing_content = "Please supply all information.";
  $email_invalid   = "Email Address Invalid.";
  $message_unsent  = "Message was not sent. Try Again.";
  $message_sent    = "Thanks! Your message has been sent.";

  //user posted variables
  $name = $_POST['message_name'];
  $email = $_POST['message_email'];
  $message = $_POST['message_text'];
  $human = 2;

  //php mailer variables
  $to = get_option('admin_email');
  $subject = "Someone sent a message from ".get_bloginfo('name');
  $headers = 'From: '. $email . "\r\n" .
    'Reply-To: ' . $email . "\r\n";

  if(!$human == 0){
    if($human != 2) my_contact_form_generate_response("error", $not_human); //not human!
    else {

      //validate email
      if(!filter_var($email, FILTER_VALIDATE_EMAIL))
        my_contact_form_generate_response("error", $email_invalid);
      else //email is valid
      {
        //validate presence of name and message
        if(empty($name) || empty($message)){
          my_contact_form_generate_response("error", $missing_content);
        }
        else //ready to go!
        {
          $sent = wp_mail($to, $subject, strip_tags($message), $headers);
          if($sent) my_contact_form_generate_response("success", $message_sent); //message sent!
          else my_contact_form_generate_response("error", $message_unsent); //message wasn't sent
        }
      }
    }
  }
  else if ($_POST['submitted']) my_contact_form_generate_response("error", $missing_content);

?>

<?php get_header(); ?>

  <div id="primary" class="site-content">

    </div><!-- #content -->
  </div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

如@Matthew Goheen 所述； PHPMailer 会有很大帮助。 您需要一个带有按钮的 html 表单:

<form action="phpmailingscript.php" method="POST">
    <input type="text" name="information"></input>
    <button type="submit">Submit</button>
</form>

此表单会将表单数据发布到 phpmailingscript.php。 要从 php 脚本访问此信息:

<?php   
if(isset($_POST['information']){
    $information = $_POST['information'];
}

然后你需要实现 phpmailer 来发送邮件
