"Notice: Undefined variable:"

[narco]

Hey. I was wondering if someone could help me with something.
I'm updating an existing osCommerce for someone, and when uploading the updated index.php I accidentally did a stripslash. I'm not sure how I did this, or what one is!

Foolishly I did not save a backup, since I was only changing one spelling mistake, I did not see it necessary.

I'm trying to repair the damaged index.php, but I am not having any success.

the error the website is giving is:

Notice: Undefined variable: category_depth in [server URL] on line 48

Notice: Undefined variable: category_depth in [server URL] on line 67

Notice: Undefined variable: category_depth in [server URL] on line 70

The code I have is as follows:

<?php
/*
  $Id: index.php,v 1.1 2003/06/11 17:38:00 hpdl Exp $

} elseif ($category_depth == 'top') {

}
?>

Can anyone help me?

Thanks

The problem is that $category_depth is not defined anywhere in your code. I doubt that is a result of a stripslash or changing one spelling mistake. What it might be a result of is that the code expects PHP's register_globals setting to be turned on, but it is not on your server. (Current best practices say to have register_globals off and not write code that requires it, but there is still a lot of PHP code out there that does.)

To check the current setting, either run a [man]phpinfo/man in a script and find the register_globals setting, or just do:

echo ini_get['register_globals'];

If it is set to off and either you cannot change it to on or you'd prefer to leave it off (my recommendation), then you might want to take a look at this ocCommerce patch: http://www.oscommerce.com/community/contributions,2097

Thanks for your fast reply 🙂

The thing is, the website worked before I uploaded the new version of index.php, so it can't be a setting on the server. I ran a phpinfo() anyway, register_globals is ON and at the bottom of the phpinfo() page it said:

Notice: Use of undefined constant register_global - assumed 'register_global' in [server address]\index.php on line 8

Warning: phpinfo() expects parameter 1 to be long, string given in [server address]\index.php on line 8

<?php

// Show all information, defaults to INFO_ALL
phpinfo();

// Show just the module information.
// phpinfo(8) yields identical results.
phpinfo(register_global);

?> 

which makes line 8 the line that says "phpinfo(register_global)".
