php support needed

i have been working on a script for a few weeks now, and nearly at
final stages of releasing it, but i need help with the following

PHP Code:


		
			
function blockAccess($message) {
    global $forbidbad, $badcookie, $myredir;
    if ($forbidbad == true) {
        writeCookie($badcookie, $message, $myredir);
    }

i want to insert a redirect script / code into this
basically the above writes a cookies to block access, so the idea is if the statement above is true the redirect to a given $varaiable set in admincp

You could use the vbulletin function print_standard_redirect():

Code:

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

/**

* Returns eval()-able code to initiate a standard redirect

*

* The global variable $url should contain the URL target for the redirect

*

* @param        mixed        Name of redirect phrase, or array if constructing a phrase.

* @param        boolean        If false, use the name of redirect phrase as the phrase text itself

* @param        boolean        Whether or not to force a redirect message to be shown

* @param        integer        Language ID to fetch the phrase from (-1 uses the page-wide default)

* @param        bool        Force bypass of domain whitelist check

*

* @return        none (the session is re-directed).

*/

function print_standard_redirect($redir_phrase, $isphrase = true, $forceredirect = false, $languageid = -1, $bypasswhitelist = false)

*/

function print_standard_redirect($redir_phrase, $doquery = true, $forceredirect = false, $languageid = -1)

{

so the $redir_phrase its self will become the URL ?
if so, all i need to do is register the variable as follows

PHP Code:


		
			
$redir_phrase = $vbulletin->options['myredirect'];

would this be what i need to do ?

Oh, right, I should have mentioned: you would set $vbulletin->url to the url, like:

Code:

$vbulletin->url = $vbulletin->options['myredirect'];

print_standard_redirect($redir_phrase);

That assumes that $redir_phrase is a phrase name. If it's the actual text, then you would want the second parameter to print_standard_redirect to be false (it's true by default).

Also, print_standard_redirect will use http headers to do a redirect so that the user won't see the message unless their browser doesn't support header redirects (I have no idea if that even happens at all these days). If you want to be sure that the message is displayed, use true for the third parameter.

Edit: also I forgot that I had the vb3 code loaded when I copied the description of print_standard_redirect() above - I replaced it with the vb4 version. This brings up another issue: if you're redirecting to a url that isn't part of your site, you might need to set the "bypasswhitelist" parameter to true.

i am not sure if you understand

all my functions are called as

PHP Code:


		
			
function blockAccess

these are the badcookies

PHP Code:


		
			
global $forbidbad, $badcookie

this is the full code

PHP Code:


		
			
function blockAccess($message) {
    global $forbidbad, $badcookie, $myredir;
    if ($forbidbad == true) {
        writeCookie($badcookie, $message, $myredir);
    }
    echo
    <<<HTML
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>403 Forbidden</title>
<meta name="robots" content="noindex" />

</head>
<BODY>

<H1>! Forbidden !</H1>

<BR>
<P>You have been taken to this page for a reason :
<P>A) your a bad bot.
<P>B) you maybe a spammer.
<P>C) You may of been blacklisted

</BODY>
</html>
HTML;
    die();
}

i want to remove

PHP Code:


		
			
    echo
    <<<HTML
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>403 Forbidden</title>
<meta name="robots" content="noindex" />

</head>
<BODY>

<H1>! Forbidden !</H1>

<BR>
<P>You have been taken to this page for a reason :
<P>A) your a bad bot.
<P>B) you maybe a spammer.
<P>C) You may of been blacklisted

</BODY>
</html>
HTML;
    die();
}

so that i can create a redirect using my current function

PHP Code:


		
			
function blockAccess

i need it to actually redirect to a chosen URL thats in this variable

PHP Code:


		
			
$myredir = $vbulletin->options['redirecturl'];

I don't know if I understand either. Are you not able to call print_standard_redirect(), or is it that you don't think it does what you want? Why not this:

Code:

function blockAccess($message) {

    global $forbidbad, $badcookie, $myredir;

    if ($forbidbad == true) {

        writeCookie($badcookie, $message, $myredir);

    }

    

    global $vbulletin;

    $vbulletin->url = $myredir;

    print_standard_redirect('phrase_to_show');

}

}

i get this with the above

Parse error: syntax error, unexpected T_VARIABLE, expecting ',' or ';'

kh99	10-27-2012 10:44 PM

oops - it had a typo, it was missing a ';'. I fixed it in my post above.

Is that a message from somewhere else in your code?

Edit: Maybe try this:

Code:

print_standard_redirect('phrase_to_show', true, false, -1, true);

i am just wondering if this is due to me running this in a plugin, or if i need to register the vbulletin cookie ?

kh99	10-27-2012 11:24 PM

Well, I made another typo and left out a comma - it should have been:

Code:

print_standard_redirect('phrase_to_show', true, false, -1, true);

But that error message you posted happens if your code produces any output before you call print_standard_redirect(). I probably shoudlhave started out by asking, where are you calling your function from? Is it a custom script or a plugin?

detected that the server is redirecting the request for this address in a way that will never complete.

it redirects as should but shows that error in the browser

Do you know what $myredir is set to? Maybe try this: temporarily add this code before the call to print_standard_redirect:

Code:

die("redirect to '$myredir'");

Is your plugin using hook global_start? Try looking at what's on line 424 (that might not be the right line because it includes all plugins using hook global_start).

looks like its not gonna work they way i need it so i thought about this

if (!$vbulletin->options['agturnoff'])

eval(standard_error($vbulletin->options['agblacklistmessage']

how would i change it, instead of

PHP Code:


		
			
function blockAccess($message) {
    global $forbidbad, $badcookie, $myredir;
    if ($forbidbad == true) {
        writeCookie($badcookie, $message, $myredir);
    }
    
    global $vbulletin
    $vbulletin->url = $myredir;
    print_standard_redirect('phrase_to_show');
}
