Custom error-handler based on vBulletin templates · **Released**: 05-10-2004

What this hack does?
---------------------------

UPDATE: Improved instruction.txt, fixed for those who use external style sheets

This hack adds a custom error-handler to your site using the vBulletin template engine to display the appropriate errors (e.g. 404 File not Found, 403 Forbidden, etc).

Demo
-------
Go to my site and enter some non-existing url. E.g. Random 404 Error. Or try to access my /cgi-bin path to receive a 403 error.

What to do?
----------------
queries to run: 0
templates changed: 0
templates added: 1 (ERROR_SHELL)
files changed: 1 (.htaccess)
files added: 1 (error.php)

Time needed to install
----------------------------
< 5 mins

This is very useful for anybody writing custom hacks outside of their vb3 base directory and storing css as file:

Nice to see my tip actually worked

I love the skin on your site. Did you do that?

Yep, that's homemade.

Have you thought about releasing it at all?

One useful bit of info

try

Code:

<base href="$vboptions[bburl]" />

and it should work across all boards

you could include that code in your template

Also a switch($_SERVER['REDIRECT_STATUS']) would probably be a nicer way to code this ... rather than all those else if's

Just a personal preference thing

[high]* Natch clicks install just the same

[/high]

Great idea!

Great idea!

The $vboptions[bburl] doesn't work for stylesheets as files. I just tested it. You have to have the absolute path for the home page to work right.

How would you set up the switch code?

Natch · #31 05-13-2004, 03:30 PM

As I mentioned in the post above, this code can be more efficient (and easier to add new error codes) witha switch statement:

Find:

PHP Code:


			
if(isset($_SERVER['REDIRECT_STATUS']))

{

    if ($_SERVER['REDIRECT_STATUS']=="404") 

    {

        $error['title'] = "404 File Not Found";

        $error['description'] = "The web server cannot find the file you asked for. Check the URL to ensure that the path is correct.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if you believe that the mistake is on our part.";

    }

    elseif ($_SERVER['REDIRECT_STATUS']=="403") {

        $error['title'] = "403 Forbidden";

        $error['description'] = "You don't have permission to access this document on this server.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if you think that there is a mistake.";

    }

    elseif ($_SERVER['REDIRECT_STATUS']=="401") {

        $error['title'] = "401 Unauthorized";

        $error['description'] = "The URL you are requesting requires proper authentication.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if you think that there is a mistake.";

    }

    elseif ($_SERVER['REDIRECT_STATUS']=="500") {

        $error['title'] = "500 Internal Server Error";

        $error['description'] = "We encountered an unexpected condition.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us to report this problem.";

    }

    elseif ($_SERVER['REDIRECT_STATUS']=="503") {

        $error['title'] = "503 Service Unavailable";

        $error['description'] = "We are currently unable to handle your request due to a temporary overloading or maintenance of the server.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if this problem persists.";

    }    

    else

    {

        $error['title'] = "Unknown Error: " . $_SERVER['REDIRECT_STATUS'];

        $error['description'] = "We are currently unable to handle this error.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if this problem persists.";        

    }

}

else

{

        $error['title'] = "Unknown Error";

        $error['description'] = "We are currently unable to handle this error.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if this problem persists.";        

}

Replace with:

PHP Code:


			
if(!isset($_SERVER['REDIRECT_STATUS']))

{

        $error['title'] = "Unknown Error";

        $error['description'] = "We are currently unable to handle this error.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if this problem persists.";        

}

else switch($_SERVER['REDIRECT_STATUS'])

{

    case("404"):

        $error['title'] = "404 File Not Found";

        $error['description'] = "The web server cannot find the file you asked for. Check the URL to ensure that the path is correct.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if you believe that the mistake is on our part.";

    break;

    case("403"):

        $error['title'] = "403 Forbidden";

        $error['description'] = "You don't have permission to access this document on this server.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if you think that there is a mistake.";

    break;

    case("401"):

        $error['title'] = "401 Unauthorized";

        $error['description'] = "The URL you are requesting requires proper authentication.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if you think that there is a mistake.";

    break;

    case("500"):

        $error['title'] = "500 Internal Server Error";

        $error['description'] = "We encountered an unexpected condition.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us to report this problem.";

    break;

    case("503"):

        $error['title'] = "503 Service Unavailable";

        $error['description'] = "We are currently unable to handle your request due to a temporary overloading or maintenance of the server.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if this problem persists.";

    break;

    default:

        $error['title'] = "Unknown Error: " . $_SERVER['REDIRECT_STATUS'];

        $error['description'] = "We are currently unable to handle this error.";

        $error['contact'] = "Please <a href=\"$vboptions[bburl]/$vboptions[contactuslink]\">contact</a> us if this problem persists.";        

}

Also (to follow all those W3C tips about the TITLE tags) ...

In the ERROR_SHELL template, find:

HTML Code:

<title>$vboptions[bbtitle]</title>

Replace with:

HTML Code:

<title>$error[title] - $vboptions[bbtitle]</title>

UPDATED: thanks Boofo for the heads up about the missing break;
