WAMP环境下PHP表单GET方法异常，点击提交下载PHP文件

Hey, let's work through this issue step by step. When your welcome_get.php file downloads instead of running after form submission, it means your WAMP server isn't configured to parse PHP code—your browser is treating it like a regular static file instead. Here's how to fix this, plus a quick tweak to your form code that's causing another hidden issue:

1. 确认WAMP服务正常运行 #

• Open your WAMP manager (the icon in your system tray). Make sure the icon is green—if it's orange, that means Apache or MySQL isn't running.
• If it's not green, right-click the icon, hover over Apache and select Start Service, then do the same for MySQL if needed. Wait for the icon to turn green before moving on.

2. 确保Apache加载了PHP模块 #

• Right-click the WAMP icon, go to Apache > Modules.
• Look for an entry like phpX.X.X (replace X.X.X with your installed PHP version, e.g., php8.2.0). Make sure this option is checked.
• If it wasn't checked, click to select it, then restart Apache via Apache > Restart Service.

3. 验证Apache配置文件中的PHP关联设置 #

• From the WAMP icon, select Apache > httpd.conf to open the main Apache config file.
• Search for these lines (they might be scattered in the file):

  LoadModule php_module "${INSTALL_DIR}/bin/php/phpX.X.X/php8apache2_4.dll"
  AddHandler application/x-httpd-php .php
  PHPIniDir "${INSTALL_DIR}/bin/php/phpX.X.X"
  

• Ensure none of these lines start with a # (which would comment them out). If they do, remove the # at the start of each line.
• Save the file, then restart Apache again.

4. 检查文件位置和访问方式 #

• Make sure both your HTML form file and welcome_get.php are saved in WAMP's root directory: this is usually wamp64/www (for 64-bit WAMP) or wamp/www.
• Always access your site via http://localhost/your-file-name.html (replace your-file-name with your actual HTML file name) instead of double-clicking the local file directly.

Bonus: Fix Your Form Code (It Won't Pass Data Right Now!) #

Your current HTML form has two small issues that will prevent PHP from getting the email address, even after fixing the WAMP problem:

1. The email input doesn't have a name attribute—PHP uses the name (not id) to retrieve form data.
2. You don't need to close <input> tags (they're self-closing in HTML).

Here's the corrected form code:

<form action="welcome_get.php" method="get">
  <section class="contact bg-primary" id="contact">
    <div class="container">
      <h2>Abonnez vous par mail!</h2>
      <input type="email" id="email" name="email" size="50" placeholder="Entrez votre adresse e-mail">
    </div>
    <div class="mail-submit">
      <input type="submit" id="submit" value="Je m'abonne">
    </div>
  </section>
</form>

And here's a more robust version of your PHP code (to avoid errors if no email is submitted):

<html>
<body>
<?php
if (isset($_GET["email"])) {
    // Use htmlspecialchars to prevent XSS attacks
    echo "Your email address is: " . htmlspecialchars($_GET["email"]);
} else {
    echo "No email address submitted!";
}
?>
</body>
</html>

Once you've gone through all these steps, reload your form page via localhost, submit the email, and your PHP file should execute correctly instead of downloading.
