Hi,
- Your code is not perfect.
- A code that runs without fault somewhere can not be considered flawless.
- You want to use an array with an index 'action', but this index has never been defined, that is to say, nowhere you have given it any value.

Hi,
> if($_GET['action']=="login"
The problem is If $_GET['action'] does not exist!
---------------------------------------------------------------
Documentation Apache - Documentation PHP - Documentation MySQL - Wampserver install files & addons
> if($_GET['action']=="login"
The problem is If $_GET['action'] does not exist!
<?php
// login.
if(isset($_GET['action']) && $_GET['action']=="login" ) {
$username=$_POST['username'];
$password=$_POST['password'];
....
or to cover all other cases:
<?php
// login.
if(!isset($_GET['action'])) $_GET['action'] = "";
if($_GET['action']=="login" ) {
$username=$_POST['username'];
$password=$_POST['password'];
...
or
<?php
// login.
$action = (isset($_GET['action']) ? $_GET['action'] : "" );
if($action == "login" ) {
$username=$_POST['username'];
$password=$_POST['password'];

The value $_GET['action'] obviously does not exist in the $_GET array.
Add this debug code.

If you are going to supply an error message then please supply all of it.
This error comes with a line number and a file name.
Is this the file containing the error, I dont think so.
Also this site is for people having problems getting WAMPServer running, and not for people who dont know how to code PHP.
