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.

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