Question: The URL of a form includes some GET parameters. 

The form submits via post to "" (the same page). 

It turns out, that includes the GET parameters. Is there a way to submit to the same page without including all of the GET parameters?

Answer: 
you could use:

```
action="<?php echo $_SERVER['REQUEST_URI']?>"

```

or:

```
action="<?php echo $_SERVER['SCRIPT_FILENAME']?>"

```

See: <http://php.net/manual/en/reserved.variables.server.php>
Try using 

```
action="?"

```

instead of 

```
action=""

```

as you do it (if I understood correctly)
