如何使复选框信息附加到电子邮件

Question

我的联系表单上有 3 个复选框。除了复选框之外，该表单适用。这些框是可选择的，但一旦点击“提交”按钮，选择就会显示在“感谢您的评论”页面上。我不知道如何让复选框选择出现在实际电子邮件中。

我尝试了各种我发现人们在论坛和教程中使用的 php 函数。没有将复选框信息附加到电子邮件中。我似乎找不到任何知道如何做到这一点的人。

“内爆”功能不起作用。 “回声”功能不起作用。 “数组”功能不起作用。会发生什么？

这是我的html：

<section class="contact">   
    <form id="contact" action="html_form_send.php" method="post">
    <fieldset title="About you">
    <legend><span>About you</span></legend>
      <label for="name">Name</label>
      <input type="text" name="name" id="name" tabindex="10"  class="txtinput" placeholder="Your name" required>
      <label for="email">Email</label>
      <input type="email" name="email" id="email" tabindex="20" class="txtinput" placeholder="valid email" required>
      </fieldset>
      <fieldset title="Your turn">
      <legend><span>Your turn</span></legend>
    <p>What, exactly then, are you after?</p>
    <div>
        <div class="tag">Checkbox1</div>         
        <input type="checkbox" id="checkbox-1-1" name="option[ ]" class="regular-checkbox big-checkbox" value="salvation" /></input><label for="checkbox-1-1"></label>
   </div>
   <div>
        <div class="tag">Checkbox2</div>
        <input type="checkbox" id="checkbox-2-1" name="option[ ]" class="regular-checkbox big-checkbox" value="question" /><label for="checkbox-2-1"></label>
  </div>
  <div>
        <div class="tag">Checkbox3</div>
        <input type="checkbox" id="checkbox-3-1" name="option[ ]" class="regular-checkbox big-checkbox" value="other" /><label for="checkbox-3-1"></label>
  </div>
       <label for="comment" class="inline"></label>
          <label for="discourse">Write your comments here</label>
         <textarea id="discourse" name="discourse" tabindex="30" class="txtinput" rows="7" placeholder="This is where your thoughts go">
         </textarea>

    <section id="buttons">
    <input type="reset" name="reset" id="resetbtn" class="resetbtn" value="Reset">
    <input type="submit" name="submit" id="submitbtn" class="submitbtn" tabindex="40" value="Send away!">
    <br style="clear:both;">
    </section>

这是我的 php：

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

    // CHANGE THE TWO LINES BELOW
    $email_to = "email@email.org";

    $email_subject = "website feedback";


    function died($error) {
        // your error code can go here
        echo "We're sorry, but there's errors found with the form you submitted.<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['discourse'])) {
        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
    $discourse = $_POST['discourse']; // 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($string_exp,$name)) {
    $error_message .= 'The Name you entered does not appear to be valid.<br />';
  }
   if(strlen($discourse) < 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);
    }

    $email_message .= "Name: ".clean_string($name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Comments: ".clean_string($discourse)."\n";

    if(isset($_POST["submit"])) //Checks if the send button is pressed
    {

        echo $_POST["email"]; //print your email

        //check all the checkboxes if anyone is checked. this is a lot of work to do.
        //All checkboxes are checked one by one
    if(isset($_POST["salvation"]))
        echo $_POST["salvation"];

    if(isset($_POST["question"]))
        echo $_POST["question"];

    if(isset($_POST["other"]))
        echo $_POST["other"];    }
        if(isset($_POST["submit"])) //Checks if the send button is pressed
   {
    echo $_POST["name"]; //print your name
    echo $_POST["email"]; //print your email

    if(isset($_POST["option"])) //checks if any interest is checked
    {
        foreach($_POST["option"] as $value) //Iterate the interest array and get the values
        {
            echo  $value;  //print the values          }         }     }


  // 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);  }
  ?>

  <!-- place your own success html below -->
        <script language="javascript" type="text/javascript">
        alert('Thank you for contacting us.');
        window.location = 'feedbackform.html';
        </script>    
  <?php
  die();
  ?>   

Answer 1

        <div class="tag">Checkbox2</div>
        <input type="checkbox" id="checkbox-2-1" name="option1" class="regular-checkbox big-checkbox" value="yes" /><label for="checkbox-2-1"></label>
  </div>

尝试命名每个选项复选框，然后按如下方式检索它们：

if(isset($_POST['option1']) && $_POST['option1'] == 'yes'){
    echo "Yes, this was checked";
}else{
    echo "No, this wasn't checked";
}    

if 语句的作用是检查该选项是否已设置、含义是否具有值，如果已设置则获取该值。然后它相应地输出
