Answer 1

You can use get and post at the same time, but you shouldn't. If you want to continue to send the ID this is as simple as:

<form ...
   <input type="submit" ...
   <input type="hidden" name="id"
      value="<?php echo htmlspecialchars($_GET['id'], ENT_QUOTES); ?>" />
</form>

Answer 2

Of course you can not use GET and POST methods simultaneously.

However you can use a query string while sending a form using POST method, which being used to populate $_GET array.

To find a certain error you have to provide more info. At least 2 things:

• how does HTML form look
• what do yo see in the query string after posting the form.

and errr...

• do you use any header redirects in the form processing?
