help me with this notice.

When I select "go" button then get notice as follows:

!PHP Notice: Undefined variable: firstname in E:\Studying\PHP\handon\welcome.php on line 2 PHP Notice: Undefined variable: lastname in E:\Studying\PHP\handon\welcome.php on line 2


I have two .php file. That is ex4.php and welcome.php with code as follows:

ex4.php
<html>
<body>
<FORM ACTION="welcome.php" METHOD=GET>
First Name: <INPUT TYPE=TEXT NAME="firstname"><BR>
Last Name: <INPUT TYPE=TEXT NAME="lastname">
<INPUT TYPE=SUBMIT VALUE="GO">
</FORM>
</html>
</body>

welcome.php

<html>
<?php echo( "$firstname $lastname!" );?>
</html>

Hi defeater, try this, call it test.php and test it...

<html>
<body>
<FORM ACTION="<? PHP_SELF ?>" METHOD=POST>
First Name: <INPUT TYPE=TEXT NAME="firstname"><BR>
Last Name: <INPUT TYPE=TEXT NAME="lastname">
<INPUT TYPE=SUBMIT VALUE="GO" NAME="hallobutton">
</FORM>
</html>
</body>

<?

if ($hallobutton) {

$firstname = ($firstname);
$lastname = ($lastname);

echo "Hallo $firstname $lastname!";

}

?>

Hope this helps

Other than the form method change to POST from GET, you may also find the snag within the php configuration. If register globals is set to OFF (as is default for all recent builds), you'd need either

$_POST['firstname'];
or
$HTTP_POST_VARS['firstname'];
