Notice: Undefined variable: nickname in /home/httpd/vhosts/testing.com/httpdocs/uploading.php on line 32

PHP Code:

include_once("config.php");
checkLoggedIn("yes");
doCSS();
?>

The short answer is :

yes.. you have to define 'nickname'... but specifically the session variable for 'nickname' - $_SESSION['nickname']

You must not be loading it somewhere.... are other parts of the code working?

Maybe you need to modify your .htaccess file, because typically going from one server to another, often times sessions get handled differently. I would recommend having an .htaccess file at the root of your webpages that has the following content:

Filename: .htacccess

Code:

php_value error_reporting 0
php_value variables_order GPCS
php_value gpc_order GPC
php_flag asp_tags off
php_flag magic_quotes_gpc off
php_value output_buffering 4096

I've had problems before... OH One way to see if one server is configured differently than another is to run the following script on each one:

Filename: test.php (put everything below in one file... it works great)

PHP Code:


<?php

    define('boolean', 1);
    define('string', 2);
    define('integer', 3);

    $php_ini_all = Array(
        Array(string, 'arg_separator.input'),
        Array(string, 'arg_separator.output'),
        Array(boolean, 'display_errors'),
        Array(boolean, 'display_startup_errors'),
        Array(boolean, 'magic_quotes_runtime'),
        Array(integer, 'error_reporting'),
        Array(string, 'variables_order'),
        Array(string, 'gpc_order')
    );
        
    $php_ini_perdir = Array(
        Array(boolean, 'asp_tags'),
        Array(boolean, 'magic_quotes_gpc'),
        Array(string, 'output_buffering'),
        Array(boolean, 'register_globals'),
        Array(boolean, 'short_open_tag')
    );
?>

<?php
    function display_php_conf() {
     echo "<PRE>";
        foreach ( $GLOBALS['php_ini_all'] as $option ) {
            $value = ini_get($option[1]);
            echo "ini_set('$option[1]', '$value');\n";
        }
        echo "</PRE>";
    }

    function display_htaccess_conf() {
        global $php_ini_all, $php_ini_perdir;
        echo "<pre>";
        foreach ( array_merge($php_ini_all, $php_ini_perdir) as $option ) {
            $value = ini_get($option[1]);
            
            if ( $option[0] == boolean ) {
                $value = $value ? 'on' : 'off';
                $directive = 'php_flag';
            } else {
                $directive = 'php_value';
            }

            echo "$directive $option[1] $value\n";
            
        }
                echo "</pre>";
    }
?>

Hope that helps ya.
