Hello Everyone,
I had like to reject some browsers to enter my site, so first i installed ZH-Restrict A Browser, but blocking javascript on the browser was letting you easly passing through it, then i started to write a more crude, but php, version of the addon, that is different, but with the same target, not enabling some browser to view your page.

To do so i simply entered that string on the global.php in the root directory of the vbulletin installation (global.php, so it will work from every page of your vbulletin installation):

PHP Code:


$browsername = $_SERVER['HTTP_USER_AGENT'];

$kz_b1 = '-yourrejectingbrowsername1-';

$kz_b2 = '-yourrejectingbrowsername1-';

$kz_f1 = strpos($browsername, $kz_b1);

$kz_f2 = strpos($browsername, $kz_b2);

if ($kz_f1 === false) {

    if ($kz_f2 === false) {

    } else {

        header("Location: http://www.where-you-want-to-send-people-to-do-it-externally-of-your-vbulletininstallation-or-it-will-give-you-a-loop-bug-for-example-to-download-an-other-browser-like-firefox.com");

    }

} else {

    header("Location: http://www.where-you-want-to-send-people-to-do-it-externally-of-your-vbulletininstallation-or-it-will-give-you-a-loop-bug-for-example-to-download-an-other-browser-like-firefox.com");

}

I installed it after the following string, and it's working perfectly:

PHP Code:


// #############################################################################

// set the referrer cookie if URI contains a referrerid

if ($vbulletin->GPC['referrerid'] AND !$vbulletin->GPC[COOKIE_PREFIX . 'referrerid'] AND !$vbulletin->userinfo['userid'] AND $vbulletin->options['usereferrer'])

{

    if ($referrerid = verify_id('user', $vbulletin->GPC['referrerid'], 0))

    {

        vbsetcookie('referrerid', $referrerid);

    }

}

OFC instead of "-yourrejectingbrowsername1-" you must place the name of the browser you want to reject, for example "MSIE" (Internet explorer), "Safari" (Safari), "Firefox" (Firefox), "Opera" (Opera) i know the name of just those 4, more is Konqueror, gecho...

Instead of two you may want to reject just one browser, than:

PHP Code:


$browsername = $_SERVER['HTTP_USER_AGENT'];

$kz_b1 = '-yourrejectingbrowsername1-';

$kz_f1 = strpos($browsername, $kz_b1);

if ($kz_f1 === false) {

} else {

    header("Location: http://www.where-you-want-to-send-people-to-do-it-externally-of-your-vbulletininstallation-or-it-will-give-you-a-loop-bug-for-example-to-download-an-other-browser-like-firefox.com");

}

Here is a working example, this one reject safari and IE, and send you to firefox download page:

PHP Code:


$browsername = $_SERVER['HTTP_USER_AGENT'];

$kz_b1 = 'MSIE';

$kz_b2 = 'Safari';

$kz_f1 = strpos($browsername, $kz_b1);

$kz_f2 = strpos($browsername, $kz_b2);

if ($kz_f1 === false) {

    if ($kz_f2 === false) {

    } else {

        header("Location: http://www.spreadfirefox.com/en-US/worldrecord/");

    }

} else {

    header("Location: http://www.spreadfirefox.com/en-US/worldrecord/");

}

I'm using Php 4.4, if you'r with a different version and it doesn't work try to change the string:

PHP Code:


header("Location: http://www.url.com");

With the command http_redirect, if you'll google you'll find more information about, actually i can't help without a different php version to test it.

Enjoy.
