How do I clear $_GET from my url?

Posted on 2010-09-05
Last Modified: 2012-05-10

Bit tricky to explain... I have a script which when submited, will return to the same page with the $_GET variables. If I submit the page again, I need it to forget the original variables and replace the url with the new variables.

So the url might look like

When i resubmit the form with different variables, e.g. ID = 567 & Price = 2083 i want the url to look like:

However what actually comes up is

Can anyone help?

I can only guess that the ACTION of the form is being dynamically created, maybe using something like $_SERVER['PHP_SELF']. Each time the form is submitted to itself, the ACTION contains the current GET variables and the new GET variables get added to it.

Check on how you're setting the form action, and you mind find your problem.

Without seeing code, it's difficult to be precise.

Also, could I suggest you to use POST method instead of GET ?

POST method has some advantages, such as hidding the variable values from the URL, which is more secure.

Just completely remove the       action=""          section of your form tag.

The form wil then submit to the root file address without the query string.

@chrisstanyon - you are write in the dynamic form. the code i have is below.


mysql_select_db($database_bookedy, $bookedy);

$query_emergency = "SELECT * FROM emergency";

$emergency = mysql_query($query_emergency, $bookedy) or die(mysql_error());

$row_emergency = mysql_fetch_assoc($emergency);

$totalRows_emergency = mysql_num_rows($emergency);

$colname_booking = "-1";

if (isset($_GET['id'])) {

  $colname_booking = (get_magic_quotes_gpc()) ? $_GET['id'] : addslashes($_GET['id']);


mysql_select_db($database_bookedy, $bookedy);

$query_booking = sprintf("SELECT * FROM booking WHERE bookingid = %s", $colname_booking);

$booking = mysql_query($query_booking, $bookedy) or die(mysql_error());

$row_booking = mysql_fetch_assoc($booking);

$totalRows_booking = mysql_num_rows($booking);


<?php $bookingid = $row_booking['bookingid']; ?>


$paxno = $_GET['pax']+1;

$paxget = $_GET['pax'];


if ($row_booking['pax']==$paxget) {

$nexturl = "$bookingid";

$button = "2";




$nexturl = "$bookingid&pax=$paxno";

$button = "1";




function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 


  $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;

  switch ($theType) {

    case "text":

      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";


    case "long":

    case "int":

      $theValue = ($theValue != "") ? intval($theValue) : "NULL";

    case "date":

      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";


    case "defined":

      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;



  return $theValue;

Looking through your code, your form is being sent using POST, although there also appears to be some GET data passed through as well.

In your code, line 59-61 sets the form action to include the Query string (the GET variables).

Remove lines 60 - 62 and see how you get on. If you need these values passing to the next page, then add them into your form as Hidden Inputs.

Not really sure I follow your program logic completely, so removing those lines may break something else.

I actually worked out a completly different method by taking the total number of columns found and it's worked but thanks for your help!
