<head>
<title>test the form</title>
</head>
<?
if($loggingIn)
echo ("ok");
?>
<body>
<form action=<? print $PHP_SELF; ?> method=post>
<input type=hidden name=loggingIn value="true">

<table border="1"  align=center cellspacing="0" cellpadding="3">
  <tr>
    <td colspan="2" align="center" >Login</td>
  </tr>
  <tr>
	<td align="right" >Username</td>
    <td><input type='text' name='Username' size='30'></td>
  </tr>
  <tr>
    <td>Password</td>
    <td><input type='password' name='Password' size='30'></td>
  </tr>
  <tr>
    <td colspan="2" align="center"><input type='submit' name='submit' value='Login'></td>
  </tr>
</table>
</form>

</body>

why when opening this page it gives a warning that "loggingIn" is not defined?? it should not be predefined.
thanks.

you must be using php 4.2.1 and with all errors on, including notices. a notice of undefined var will be given if you use a var without initialising it first.

in a class, initialise it as an attribute with: var $myvar;

or generally do a: $myVar = null;

Instead of putting a hidden field try the following as a replacement for the <form> tag

<form action=<? echo"$PHP_SELF?loggingIn=true"; ?> method=post>
