Notice: Undefined variable: who in /home/ pr0blem can't solve

[just_m3.]

GumSlone was right from the first place you just didn't get it

this error is not important just remove ~E_NOTICE from error reporting.

by removing it means

// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);

Older versions of PHP will ignore this type of errors but all the currents versions of PHP are made to work somehow like c++ and Java.Because in Java and c++,U will need to declare a variable before initializing it.Its is very much recommended.Its very annoying doing it but programmers in C++ and Java will see it normal.
So here U were to declare :

$who="";

We declared $who to null or empty variable.After declaring it to an empty variable,You then asign $_POST to it
so it will be

$who="";
$who=$_POST['who'];

As Gumslone to said,the error is not of important so U can decide to hide it using :

error_reporting("E^NOTICE");

it is not recommended to hide all errors ,so I will not advise you to use

error_reporting("E^ALL"); or error_reporting(0);

well try E_NOTICE i know you want a error free site but thats probaly nothing to worry about.

Your script assumes that all variables ($who) are registered globally. This is a bad assumption to make.

Rather, use the variable from the $HTTP_POST_VARS array:



$who = $HTTP_POST_VARS["who"];


If you're using PHP version 4.1 or higher, you can alternatively use $_POST instead of $HTTP_POST_VARS.

Okay i spot ur problem. Um ima just explain so u can help urself debug next time.

1st error: Undefined variable who. . .
The error occurs when you are trying to assign an undefined variable. In ur case its close to dat line.

wrong:
$nix = getnick_uid($who);

correct:
$who = (int) $_GET['who'];
$nix = getnick_uid($who);

2nd error: Undefined index lstloc. Usually when the requested array index is nt found. In ur case, the $_GET array doesnt contain d lstloc index. You can fix it in the url e.g &lstloc=value or beta stil, like dis:

$lstloc = isset($_GET['lstloc']) ? $_GET['lstloc'] : NULL;
$lastloc = cleanQuery($lstloc);

3rd error: undefined var who. Same as 1st error. Solving error 1 will fix it.

4th error. Another undefined array index. This time in the $_POST array. Solve dis by:

if(empty($who)){
$mnick = isset($_POST['mnick']) ? $_POST['mnick'] : NULL;
/* if(empty($who)) is a beta way of writing if($who == "" || $who == 0) */ 

[wapmetal]

is there other way to solve this? not just hidding these errors?
