Undefined variable: ip #1

Closed kek91 closed 8 years ago

Undefined variable: $ip Error occurs in /­user/­plugins/­iplocate/­iplocate.php at line 47.

Notice exception occurs because the function is_null() just checks if the given variable is null. You may want to switch to isset() because this will check that the variable exists AND that it's not null.

Thanks for this! I'm not a PHP native, and this just never came up in testing somehow.
