五表单页面提交后跳转至感谢页，能否根据来源修改<h1>标签？

Hey Jim, great question! Let's break down how to show custom <h1> headings on your thank-you page depending on which form was submitted. Here are two solid approaches you can implement right away:

Approach 1: Pass Form Type via URL Parameter #

This is the simplest method, perfect if you don't mind the form type appearing in the URL.

• Step 1: Add a hidden field to each form
  For each of your five forms, add a hidden input that identifies the form type. For example:

  <!-- Comment Form -->
  <form action="mail-handler.php" method="POST">
    <input type="hidden" name="form_type" value="comment">
    <!-- Rest of your comment form fields -->
  </form>
  
  <!-- Contact Form -->
  <form action="mail-handler.php" method="POST">
    <input type="hidden" name="form_type" value="contact">
    <!-- Rest of your contact form fields -->
  </form>
  

  Use unique value values for each form (e.g., feedback, support, review).

• Step 2: Modify your mail handler to pass the parameter
  In your PHP mail processing file, after sending the email, redirect to the thank-you page with the form_type parameter:

  // Process the email (your existing code here)
  // ...
  
  // Get the form type from the submitted data
  $form_type = $_POST['form_type'];
  
  // Redirect to thank-you page with the form type parameter
  header("Location: thank-you.php?form=$form_type");
  exit; // Always exit after a header redirect to stop further code execution
  

• Step 3: Display the custom heading on the thank-you page
  In thank-you.php, read the URL parameter and output the matching heading:

  <?php
  // Set a default heading in case the parameter is missing
  $heading = "感谢您的提交";
  
  // Check if the form type parameter exists
  if (isset($_GET['form'])) {
      $form_type = $_GET['form'];
      // Switch heading based on form type
      switch ($form_type) {
          case 'comment':
              $heading = "感谢您的评论";
              break;
          case 'contact':
              $heading = "感谢您的联系";
              break;
          case 'feedback':
              $heading = "感谢您的反馈";
              break;
          // Add cases for your other three forms here
          default:
              $heading = "感谢您的提交";
      }
  }
  ?>
  
  <!-- Output the heading in your HTML -->
  <h1><?php echo $heading; ?></h1>
  <!-- Rest of your thank-you page content -->
  

Approach 2: Use Session Storage (No URL Parameter) #

If you prefer not to expose the form type in the URL, use PHP sessions to store the form type temporarily.

• Step 1: Add the hidden form field (same as Approach 1)
  Include the form_type hidden input in each form just like before.

• Step 2: Store form type in session in the mail handler
  Start a session at the top of your mail handler, save the form type, then redirect:

  session_start(); // Must be called before any HTML output
  
  // Process the email (your existing code here)
  // ...
  
  // Store form type in session
  $_SESSION['form_type'] = $_POST['form_type'];
  
  // Redirect to thank-you page
  header("Location: thank-you.php");
  exit;
  

• Step 3: Retrieve session data in the thank-you page
  In thank-you.php, start the session, read the stored form type, output the heading, then clear the session value (so it doesn't show up if the user refreshes the page):

  <?php
  session_start(); // Again, call before any HTML output
  
  $heading = "感谢您的提交";
  
  if (isset($_SESSION['form_type'])) {
      $form_type = $_SESSION['form_type'];
      switch ($form_type) {
          case 'comment':
              $heading = "感谢您的评论";
              break;
          case 'contact':
              $heading = "感谢您的联系";
              break;
          // Add other form cases here
          default:
              $heading = "感谢您的提交";
      }
      // Clear the session value to avoid reusing it on refresh
      unset($_SESSION['form_type']);
  }
  ?>
  
  <h1><?php echo $heading; ?></h1>
  <!-- Rest of your thank-you page content -->
  

Quick Notes #

• Make sure all forms use the same name for the hidden field (form_type) so your PHP code can read it consistently.
• Always use exit or die immediately after a header("Location: ...") redirect to prevent leftover code from running.
• For session-based approach, ensure no HTML (including whitespace) is output before session_start(), otherwise you'll get an error.
