vb.org Archive - Custom error-handler based on vBulletin templates

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;
