'Notice: Undefined index' error for "Show region's" on remote server only

'Notice: Undefined index' error for "Show region's" on remote server only

I have numerous 'Security Assist / Show region' being used all of which work fine when viewing locally. But when I upload pages to the remote server i get 'Undefined Index' notice similar to the following:

Notice: Undefined index: actions in E:\Domains\r\rtmf.org.uk-20218885\user\htdocs\federation\members\login-m.php on line 238

Ive had this before where I didn't have the '<?php require_once( "../../webassist/security_assist/helper_php.php" ); ?>' file reference at the top of the page. But this is there as it is fine when viewing locally.

I've attached a sample page that has the problem.

Any ideas?

Update this line:
<?php
if ("".$_GET['actions'] ."" == "failedLogin") { // WebAssist Show If
?>

to:
<?php
if ("".(isset($_GET['actions'])?$_GET['actions']:"") ."" == "failedLogin") { // WebAssist Show If
?>

Thanks Ray. What I don't understand is I'm using WA plugins to create these so how come they need correcting manually. What is this update doing to ensure it works remotely?

You probably don't have notices turned on to display locally. It is a difference in your php alert settings. Technically this is just a notice that can be ignored, but your remote server is configured to stop and show notices instead of ignoring them.

It looks like you manually applied the webassist show if server behavior on the page to show the failed login message... it isn't the code our wizard creates unless you are running an older version.

The issue is the value put into the show if was <?php echo($_GET['action']); ?> and php will throw a notice if you refer to a variable that doesn't exist even if it is a URL parameter. The solution could have been implemented in the UI as well by using the compare value:

<?php echo(isset($_GET['action'])$_GET['action']:""); ?>

that basically checks if the variable is set before trying to reference it's value directly.

The reason I'm having to enter them manually is because the 'OK' button on the 'Show region utility' does not work. So I can not create the code with the wizard. I have meant to post in the forum about this but haven't got round to it. I think maybe I might have based my manual efforts from an older web-site. I will try this adjustment.

In the keen time any ideas why the 'OK'button on the 'Show region utility' window is not working. Its as if its just a flat static graphic.

I think that was an issue several versions back that we resolved. Do you have the latest version of Data Bridge installed? I just tested and it appears to work correctly for me.

My version is 1.2.3 which is the latest, but I uploaded again and the OK button now works. But the 'Show region utility is till producing the same code. and not as per the example you posted.

Any ideas?

Thanks!

You have to use this syntax in the field in the show region:

<?php echo(isset($_GET['action'])$_GET['action']:""); ?>

You can only refer to:
<?php echo($_GET['action']); ?>

if there will always be an action in the url, which there won't on your page.

It is a valid input, so our extension won't catch and refuse to use it, but it doesn't know that the variable you are referencing won't always exist. Since it won't you have to use code that checks if it exists before using it like:
<?php echo(isset($_GET['action'])$_GET['action']:""); ?>

In web assist bindings we will add that automatically, but when you use the Dremweaver bindings or hand code, you need to add it manually if the variable might not exist.
