dude paul, i could have sworn i gave you a fix for this! just edit the php
ini file. you need to create a file called 'relative.path.php'. and put it
in your php include path (that you are soon to quick fucking around with
using ini_set). that file has this code in it:
<?
$parsedUri = dirname($_SERVER['PHP_SELF']);
$parsedUri .= substr($parsedUri, -1) != '/' ? '/' : '';
$relativeUri = str_replace('/', '', $parsedUri);
$relativePath = strlen($parsedUri) - strlen($relativeUri) - 1;
if ($relativePath < 0){ $relativePath = 0; }
$relativePath = str_repeat('../', $relativePath);
if (!$relativePath){ $relativePath = './'; }
?>
then i'd put this at the beginning of *EVERY* php file your site has:
<?
require_once 'relative.path.php';
?>
i'd remove every instance of ini_set('include_path', '.:..') that i saw.
that is a horrible way to get the desired effect and the programmer should
summarily be drawn and quartered. this method requires that the file
*always* be a relative distance for what you're including. it could also
severly fuck up a script that includes another and then tries to include
another...because each is setting the include_path! further, it doesn't
allow you to reuse the known relativity to call other folders for inclusion
like classes, common functions, whatever. this scenario requires *all*
includes to be in one folder. not very flexible, is it!
you'll notice that 'relative.path.php' creates a variable called
$relativePath. you'll also notice that it is compatible with all versions of
php...such that you can use it on a server that runs both php 4 or php 5.
the variable points to the root of your web application. once you know that,
you can merrily jump about. anyway, your code would become:
<?
require_once 'relative.path.php';
require_once $relativePath . 'HTML/Common.php';
?>
now it doesn't matter where your script is put in your directory structure.
as it is, your code doesn't work because ini_set('include_path','.:..')
isn't setting a valid path. the best solution would be to further abstract
your directory structure. here's what i put at the top of *EVERY* script of
my own:
<?
$pageTitle = "Welcome";
$fullHeader = true;
$securityEnabled = true;
require_once 'relative.path.php';
require_once $relativePath . 'site.cfg.php';
require_once site::$includeDirectory . 'head.inc.php';
?>
notice the use of the static site::$includeDirectory interface?
'site.cfg.php' configures the path. if i had a common header that should be
shown on a page (as i have in the above ficticious page), i could now
include it no matter where either the header nor the including page existed.
get the idea?
i have a configuration script called 'site.cfg.php'. it sets paths into
variables. so, when you implement the site, you can put your files all over
the gawd damned place and manage it all in one spot. the rest of your
scripts couldn't care less how crazy you go. they reference variables.
here's my site.cfg.php script:
<?
ini_set('display_errors' , true );
ini_set('error_reporting' , E_ALL & E_ERROR & E_WARNING );
ini_set('max_execution_time' , 0 );
ini_set('memory_limit' , '100M' );
session_start();
// site basic information
$rootDirectory = '/var/www/html/dev/';
require_once $rootDirectory . 'classes/site.class.php';
site::initialize();
site::$rootDirectory = $rootDirectory;
site::$uri = 'http' . ($securityEnabled ? 's' : '') .
'://' . $_SERVER['HTTP_HOST'];
site::$uri = 'http://' . $_SERVER['HTTP_HOST'] . '/';
site::$uploadBaseDirectory = site::$rootDirectory . 'data/';
site::$mailDropDirectory = site::$rootDirectory . 'data/mail/';
site::$adminEmail = Web Site Administrator <no.one@example.com>';
site::$title = 'SAMPLE WEB SITE;
site::$description = 'A SIMPLE PROVING GROUND';
site::$currentPage = basename($_SERVER['PHP_SELF']);
site::$classDirectory = site::$rootDirectory . 'classes/';
site::$cssDirectory = site::$uri . 'css/';
site::$host = 'tccc';
site::$errorLogFile = site::$rootDirectory . site::$host .
'.errors.log';
site::$fontDirectory = '/var/www/fonts/';
site::$homePage = site::$uri . 'index.php';
site::$htdocsDirectory = site::$rootDirectory;
site::$imagesDirectory = site::$uri . 'images/';
site::$includeDirectory = site::$rootDirectory . 'inc/';
site::$jscriptDirectory = site::$uri . 'jscript/';
site::$logo = site::$imagesDirectory . 'logo.jpg';
site::$popUpAttributes = 'addressbar=0, channelmode=0, dependent=1,
directories=0, fullscreen=0, location=0, menubar=0, resizable=1, status=0,
titlebar=0, toolbar=0';
// common php functionality
require_once site::$includeDirectory . 'functions.inc.php';
// source code security (disables 'view source' from right-click)
$enableContextMenu = true;
// site database information
require_once site::$classDirectory . 'db.class.php';
try
{
db::connect('localhost', 'user', 'password', 'db');
} catch (exception $ex) {
print "<pre>\r\n" . $ex->getMessage() . "\r\n" .
' in file ' . $ex->getFile() . "\r\n" .
' on line ' . $ex->getLine() . "\r\n" .
'</pre>';
}
// site notifcations
$emailNotify['TO'] = site::$adminEmail;
$emailNotify['CC'] = site::$adminEmail;
$emailNotify['BCC'] = '';
// get relative font sizes for the browser
require_once site::$classDirectory . 'browser.class.php';
$browser = browser::getInstance();
$sessionFonts = $browser->getFonts();
// user interaction
require_once site::$classDirectory . 'user.class.php';
$logOut = isset($_REQUEST['logOut']);
if ($logOut)
{
user::reset();
session_unset();
session_destroy();
header('location:' . site::$uri);
exit;
}
?>
i'm using php 5, so if you are using a prior version, just adjust the static
interfaces on the site class appropriately. don't know what i mean? post
that as another question here. here is my site object:
<?
class site
{
public static $adminEmail = '';
public static $classDirectory = '';
public static $cssDirectory = '';
public static $currentPage = '';
public static $description = '';
public static $errorLogFile = '';
public static $fontDirectory = '';
public static $homePage = '';
public static $host = '';
public static $htdocsDirectory = '';
public static $imagesDirectory = '';
public static $includeDirectory = '';
public static $jscriptDirectory = '';
public static $lastSecurityCode = '';
public static $logo = '';
public static $mailDropDirectory = '';
public static $popUpAttributes = '';
public static $rootDirectory = '';
public static $securityCode = '';
public static $title = '';
public static $uploadBaseDirectory = '';
public static $uri = '';
private function __clone(){}
private function __construct(){}
private static function getSecurityCode()
{
$alphabet = '2347ACEFHJKLMNPRTWXYZ'; // removed those that
look too similar
$alphabetLength = strlen($alphabet) - 1;
self::$securityCode = '';
for ($i = 0; $i < 6; $i++)
{
self::$securityCode .= $alphabet[mt_rand(0, $alphabetLength)];
}
$_SESSION['securityCode'] = self::$securityCode;
if (!self::$lastSecurityCode){ self::$lastSecurityCode =
self::$securityCode; }
}
public static function initialize()
{
self::$lastSecurityCode = $_SESSION['securityCode'];
self::getSecurityCode();
}
}
?>
the other classes mentioned in the site.cfg.php are one's that i won't get
in to. i included this one so you could see how i set my important paths and
how easy this all is to maintain. it is light-weight, manageable, scaleable,
and highly flexible.
hth,
me
