What are the potential security risks associated with using visible IDs in URLs for PHP form navigation?

Using visible IDs in URLs for PHP form navigation can expose sensitive information and make it easier for malicious users to manipulate data. To mitigate this security risk, it is recommended to use POST requests instead of GET requests when submitting form data. This way, the data is not visible in the URL and is sent securely to the server.

<form action="process_form.php" method="post">
  <!-- form fields here -->
  <input type="submit" value="Submit">
</form>
