Thanks for your reply,
I am still a bit confused though as the var error is never set! i.e. in your
code example below $error is never going to be set! Basically I have 2 pages
as follows:
page1.php - login form page
page2.php - validation page
page2.php checks the usernae and password against database and if all is
well it sends to the members area. If there was an error then it sends back
to the login page. When there is an error on page2.php I want to set a
request variabel called "$someError" with a value representing the error
that occured i.e. "Please enter a username" or "Please enter a password" or
"Invalid username" or "invalid password" etc.. Then on page1.php just before
the login form I would do:
if (!empty($_POST('someError'))) {
echo $_POST('someError');
}
//display login form.
So my question is how do I add the variable $someError to the request with
the value "invalid usernam" and disaply this on page1.php
$error = ''; //assume no errors
if(isset($_PHP['password'] && !empty($_POST['username']){
$sql = "SELECT id FROM members WHERE
username = '".$_POST['username']."'
AND password = '".$_POST['password']."'";
$result = mysql_query($sql);
if(!$mysql_num_rows($result) > 0){
$error = '<font color="red"><b>Error:</b> Invalid password</font>';
include('login.php');
exit;
}
//password ok
echo 'Welcome '.$_POST['username'].'<br>';
}else{
//first pass and $error is still empty
include('login.php');
}
