  • Error : Unable to add cookies, header already sent.

    Hello
    I've created 1 custom page by referring to vBulletin API Basics topic posted by Psionic Vision.
    Here is topic url : http://www.vbulletin.org/forum/showthread.php?t=98009
    I'm getting following error :
    Unable to add cookies, header already sent.
    File: /home2/aditya43/public_html/forums/test.php
    Line: 1
    My test.php file contains following code :
    <?php
    error_reporting(E_ALL & ~E_NOTICE);
    define('NO_REGISTER_GLOBALS', 1);
    define('THIS_SCRIPT', 'adi');
    $globaltemplates = array('adi');
    require('./global.php');
    include('aaa/tmp.php');
    $navbits = array();
    $navbits[$parent] = 'Aditya Test Page';
    $navbits = construct_navbits($navbits);
    eval('$navbar = "' . fetch_template('navbar') . '";');
    if (!$vbulletin->userinfo['userid'])
    {
    print_no_permission();
    }
    else
    {
    eval('print_output("' . fetch_template('adi') . '");');
    }
    ?>
    My template "adi" under vbulletin contains following code :
    $stylevar[htmldoctype]
    <html dir="$stylevar[textdirection]" lang="$stylevar[languagecode]">
    <head>
    <title>$vboptions[bbtitle]</title>
    $headinclude
    </head>
    <body>
    $header
    $navbar
    <if condition="$adiinitcond">
    $testcond1
    <else/>
    $testcond2
    </if>
    </table>
    $footer
    </body>
    </html>
    tmp.php file contains :
    $a=5;
    $b=6;
    $adiinitcond="$a>$b";
    $testcond1="$a is bigger";
    $testcond2="$b is bigger";
    However if i login to vbulletin forum and then access test.php, it works perfect. But as a guest it gives me above error.
    I also wanna allow guests on test.php or at least it should print vbulletin error message.

    Here is what i've done so far to get rid of above error :
    1. Removed all whitespace etc.
    2. Tried "<?php" tag without closing php tag "?>"
    3. Tested after removing "include('aaa/tmp.php');" from test.php
    4. Removed all "echo", "print" etc. from tmp.php

    The possible cause of above error is i'm trying to send data or something to browser before vbulletin cookies. So i traced my entire code and found i'm not sending anything to browser before cookies (or am i?).

    You should be posting this over at vb.org where they deal with custom coding.

    You should try giving no permission *before* you eval any templates (like your navbar).

    If you need further help, you should post this over at vb.org.
