通过 PHP 邮件传递会话变量

Question

我在使用 PHP 邮件通过多页表单流程传递 $_SESSION 变量时遇到问题。电子邮件通过得很好，尽管它们没有显示变量。我的目标是让用户在多个页面上填写表格，并将数据通过电子邮件发回给我。

第 1 页

<?php
session_start();
?>
                  <form method="post" action="submitpage.php">
              <label>
                <input type="radio" name="vehicle_type" value="car" checked />
                <img class="img-responsive" src="img/vehicle2.png">
              </label>
              <label>
                <input type="radio" name="vehicle_type" value="suv" />
                <img class="img-responsive" src="img/vehicle2.png">
              </label>
              <label>
                <input type="radio" name="vehicle_type" value="van" />
                <img class="img-responsive" src="img/vehicle2.png">
              </label>                                    
              <label>
                <input type="radio" name="vehicle_type" value="truck" />
                <img class="img-responsive" src="img/vehicle2.png">
              </label>     
              <label>
                <input type="radio" name="vehicle_type" value="none" />
                <img class="img-responsive" src="img/vehicle2.png">
              </label>                    
              </form>

第 2 页

<?php
session_start();
$_SESSION['vehicle_type'] = $_POST['vehicle_type'];
?>
                  <form method="post" action="emailexample.php" id="submit-form">
              <input type="Email" name="email">
              <input type="submit" name="submit" value="Submit" id="submitbtn">
              </form>

第 3 页

<?php
session_start();

$to      = 'myemail@gmail.com';
$subject = 'test ';
$message = "Your Vehicle Type is: " . $_POST['vehicle_type'] ."\r\n";
$headers = 'From: email@example.com' . "\r\n" .


mail($to, $subject, $message, $headers);
?>

Answer 1

第 3 页

使用 $_SESSION['vehicle_type'] 而不是 $_POST['vehicle_type']

Answer 2

在第 1 页上，您应该放置类似这样的提交按钮

<input type="submit" name="submit" value="Submit" />

第 3 页你应该改变

$message = "Your Vehicle Type is: " . $_SESSION['vehicle_type'] ."\r\n";

并且您在 $headers 变量的末尾缺少分号。应该是

$headers = 'From: email@example.com' . "\r\n";
