表单变量的回声不起作用

我想在表单内容中显示$atendee_name和$atendee_email，但它不起作用，尽管它在另一节中有效。表单变量的回声不起作用

HTML代码：

<!-- RSVP section --> 
<section id="rsvp"> 
    <div class="rsvp-form-wrap"> 
     <h2>RSVP</h2> 
     <p class="rsvp-desc"> WE'RE SO EXCITED TO CELEBRATE WITH YOU </p> 
     <form id="rsvp-form" action="sendmail.php" method="post" data-abide> 
      <div class="columns large-12"> 
       <label for="atendee-name">Name (required)</label> 
       <input id="atendee-name" name="atendee_name" type="text" placeholder="John Doe" required pattern="[a-zA-Z]+"> 
       <small class="error">Please enter your name.</small> 
      </div><!-- End .large-12 --> 
      <div class="columns large-12"> 
       <label for="atendee-email">Email Address (required)</label> 
       <input id="atendee-email" name="atendee_email" type="email" placeholder="john[email protected]" required> 
       <small class="error">Please enter a valid email.</small> 
      </div><!-- End .large-12 --> 
      <div class="columns large-4 medium-4 small-4"> 
       <label for="guests">Guests</label> 
       <select id="guests" name="guests"> 
        <option value="0">0</option> 
        <option value="1">1</option> 
        <option value="2">2</option> 
        <option value="3">3</option> 
        <option value="4">4</option> 
        <option value="5">5</option> 
       </select> 
      </div><!-- End .large-4 --> 
      <div class="columns large-8 medium-8 small-8"> 
       <label for="attending">I am attending</label> 
       <select id="attending" name="attending"> 
        <option value="Yes">Yes</option> 
        <option value="No">No</option> 
       </select> 
      </div><!-- End .large-8 --> 
      <div class="columns large-12"> 
       <input id="rsvp-submit" class="button" type="submit" value="Submit" name="rsvp_submit"> 
      </div><!-- End .large-12 --> 
     </form> 
    </div><!-- End .rsvp-form-wrap --> 
</section><!-- End #rsvp -->

PHP代码：

<?php 
ini_set('display_errors', 1); 
ini_set('display_startup_errors', 1); 
error_reporting(E_ALL); 
$name = $_POST['atendee_name']; 
$email = $_POST['atendee_email']; 
$guests = $_POST['guests']; 
$attending = $_POST['attending']; 
$formcontent="From: $name \n Attending: $attending \n Guests: $guests"; 
$recipient = "[email protected]"; 
$subject = "RSVP form"; 
$mailheader = "From: $email \r\n"; 

mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); 
echo "Thank You! Message successfully sent."; 
?>

错误：

Notice: Undefined index: atendee_name in /home/ayoudz/public_html/sendmail.php on line 5

Notice: Undefined index: atendee_email in /home/ayoudz/public_html/sendmail.php on line 6

写你的PHP代码中，如果条件如下图所示

<?php 
    ini_set('display_errors', 1); 
    ini_set('display_startup_errors', 1); 
    error_reporting(E_ALL); 
    if(isset($_POST['rsvp_submit']))//added this line 
    { 
     $name = $_POST['atendee_name']; 
     $email = $_POST['atendee_email']; 
     $guests = $_POST['guests']; 
     $attending = $_POST['attending']; 
     $formcontent="From: $name \n Attending: $attending \n Guests: $guests"; 
     $recipient = "[email protected]"; 
     $subject = "RSVP form"; 
     $mailheader = "From: $email \r\n"; 

     mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); 
     echo "Thank You! Message successfully sent."; 
    }// end if here 
?>

注：如果您通过jQuery的提交，确保变量正确或者如果PHP做在验证页面重定向传递值。

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

if (isset($_POST)) 
{ 
// POST Variables 
$name  = isset($_POST['atendee_name']) ? $_POST['atendee_name'] : ''; 
$email  = isset($_POST['atendee_email']) ? $_POST['atendee_email'] : ''; 
$guests  = isset($_POST['guests']) ? $_POST['guests'] : ''; 
$attending = isset($_POST['attending']) ? $_POST['attending'] : ''; 

// Validation: you can add a page redirection with the error message 
if (empty($name)) 
echo 'Please enter your name <br />'; 

if (empty($email)) 
echo 'Please enter your email address <br />'; 

// Mail 
$formcontent = "From: $name \n Attending: $attending \n Guests: $guests"; 
$recipient = "[email protected]"; 
$subject  = "RSVP form"; 
$mailheader = "From: $email \r\n"; 

mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); 

echo "Thank You! Message successfully sent."; 
}
