trying to post to the same page

[sempuritoza]

How do I have a form on page A and then when i click on the submit button POST to the same page, what do i have to put in my action="" and is there anything else i would have to add to be able to then work with the variables, i am thinking that i assign value to the submit button and then put an if statement in the page where :

if ( $submit == "value")
{
......

cause then once the page has been posted it should have the value right?

can someone please help me with this.....
thanx

if ($action=="") {
  // <form method="post" action="thisscript.php">
  // <input type="hidden" name="action" value="do">
  // other form html
  // </form>
}

if ($_POST['action']=="do") {
  // Stuff
