Warning/Error messages at run time

I have WAMP set up on two different computers (laptop running Windows 7 and PC running Windows XP).
I can run PHP code on the PC with no warning messages but the same code on the laptop gives messages such as:
Notice: Undefined index: submita in C:\wamp\www\trials\FormTest.php on line 9
Notice: Undefined index: aa in C:\wamp\www\trials\FormTest.php on line 19
Notice: Undefined index: ab in C:\wamp\www\trials\FormTest.php on line 20
the code seems to produce the same results in each case.
Is there some setting that toggles display/suppress of these messages?
The code executed is:
<?php session_start(); # start session
?>
<html><head><title>Form Test input</title></head>
<body>
<?php $self= $_SERVER['PHP_SELF'];
$submita= $_POST['submita'];
if ($submita){
$aa= $_POST['aa'];
$ab= $_POST['ab'];
$_SESSION['aa']=$aa;
$_SESSION['ab']=$ab;
} else {
$aa=$_SESSION['aa'];
$ab=$_SESSION['ab'];
}
# form a
$forma="<form action=\"$self\" method=\"post\">";
$forma.="aa: <input type=\"text\" name=\"aa\" size=\"3\" value=\"$aa\"> ";
$forma.="ab: <input type=\"text\" name=\"ab\" size=\"3\" value=\"$ab\"> ";
$forma.="<input type=\"submit\" name=\"submita\" value=\"Submit a\"><br> </form>";
$msga=$forma;
echo ($msga);
?>
</body></html>

Yes but u should fix the code-
u should not have a variable that is not set
Use. Isset() and empty() to check first
But in the php.ini you can suppress notice warnings by adding
~ E_NOTICE

Thanks. I like to see the warning messages (and can now fix them as you suggest) so I have removed ~E_NOTICE from php.ini in my WAMP installation which was not showing them.
Sorry, only registered users may post in this forum.
