Undefined index error.... please help

[ukndoit]

I'm getting these errors:

[Sun Nov 23 01:42:29 2003] [error] PHP Notice: Undefined index: a_form_filled in /usr/local/www/sites/vacation/insert_data.php on line 290
[Sun Nov 23 01:42:29 2003] [error] PHP Notice: Undefined variable: ip in /usr/local/www/sites/vacation/insert_data.php on line 371

Can I fix that by adding this to the index.php file, at the top:

globals $a_form_filled, $ip;

or is that ONLY for functions?

Thank you.
Richard

Undefined index usually means you're referencing arrays without using quotes.

Or that that form field (if that's where it's coming from) wasn't filled in.

Use isset() to see if the variable is set before trying to use it for anything.
