Notice: Undefined index:

Hi Jason:

Maybe you know why I'm getting this error message:

Notice: Undefined index: txtFirstName in D:\hshome\c309340\lovingpanda.com\MemberHomePage.php on line 1

When working with localhost the page doesn't generate that message, but the Web version of the page does. I've tried replacing the "txtFirstName" with other variables, but I still get the error message on the Web, but never when working on localhost.

I've attached a copy of the page in question just in case. That page opens right after Login is successful. Any suggestions?

Thank you for your attention.

your code at line 1 is:

<?php session_start(); session_register("sessUsername"); $sessUsername = $HTTP_POST_VARS['txtFirstName']; ?>

you are attempting to use a post value when none is present:
$sessUsername = $HTTP_POST_VARS['txtFirstName']

the error is saying that there is no POST variable named "txtFirstName" when the page loads.

1) $HTTP_POST_VARS is deprecated in PHP 5. in most cases, you can just use $_POST

2) Any time you reference a variable that may not exist at run time, you should use an if isset statement or you will run into Undefined index errors when the variable is not set:

if(isset($_POST['txtFirstName'])) $sessUsername = $_POST['txtFirstName'];

Jason:

What you say makes absolute sense, which is somehow the reason I tried changing the 'txtFirstname' variable to something else, to no avail. Now, should I enter the line of code you sent on line 1? Or should I substitute it for the existing line 1?

Thanks.

Jason:

No problem, I tried your suggestion and it works perfectly well.

Many thanks.

you're welcome.
