Help with

[specnyt]

Hi, good day..

I'm in a really tight spot right now, and I'm really desperate for some help..

I'm doing this plaincart for my web development class, and I've pretty much reached the end of my rope on trying to figure out 3 things! And I think those are pretty important things, so I'm asking for some help from you guys..

The main problem I'm having is that my index and everything else has an error on top saying:

Notice: Undefined index: DOCUMENT_ROOT in E:\hosting\vhosts\xxxxx.com\httpdocs\cartproject\library\config.php on line 18

Notice: Undefined index: REQUEST_URI in E:\hosting\vhosts\xxxxx.com\httpdocs\cartproject\index.php on line 7

and another thing is that my none of my pictures are showing, from my header to the products itself, there's nothing being shown but the table and background and menu..

I've already uploaded this into the webhost I'm using seeing that it was a "step" in the professor's instructions..

I'm posting the code below from config.php from the library folder.

<?php
ini_set('display_errors', 'On');
//ob_start("ob_gzhandler");
error_reporting(E_ALL);

// start the session
session_start();

// database connection config
$dbHost = 'localhost';
$dbUser = 'root';
$dbPass = '';
$dbName = 'phpwebco_shop';

// setting up the web root and server root for
// this shopping cart application
$thisFile = str_replace('\', '/', FILE);
$docRoot = $_SERVER['DOCUMENT_ROOT'];

$webRoot = str_replace(array($docRoot, 'library/config.php'), '', $thisFile);
$srvRoot = str_replace('library/config.php', '', $thisFile);

define('WEB_ROOT', $webRoot);
define('SRV_ROOT', $srvRoot);

// these are the directories where we will store all
// category and product images
define('CATEGORY_IMAGE_DIR', 'images/category/');
define('PRODUCT_IMAGE_DIR', 'images/product/');

Actually, as you guys can see, I haven't changed anything from the main code supplied. I've already tried changing the DOCUMENT_ROOT, but it still happens, and the error would still pop up, and the difference is that "DOCUMENT_ROOT" will be switched to whatever other string that I put in..

Its really hard being a newb.. Especially if web programming isn't really part of my course.. I'm supposed to be an artist..

Thank you guys in advance.. I really appreciate it..

Create your images on a page, right-click - > Properties and find the url. Post what it shows.

If $SERVER['DOCUMENT_ROOT'] is not defined in your system, there's something pretty flaky about your PHP installation. It might be useful to to try the following simple script to see what it outputs (if anything):

<?php
header('Content-Type: text/plain');
print_r($_SERVER);
?>

Also, for overall configuration and version info:

<?php
phpinfo();
?>

Hey! Thanks for the replies.. Really appreciate it.. 🙂

Mmmm... I'm really at a total lost with this.. So I'm assuming that i put the following codes in the index right? Or on the config.php?

And with the images, I checked the links, and I didn't see anything wrong.. the path is pointed to ../images/ which is the right folder..

I'm thinking this could be a problem with the "DOCUMENT_ROOT" thing..

[NogDog]

The code I suggested would be put into their own separate files (e.g.: "test.php" or whatever you want to call it). They are just to provide some information to help find out if there is something odd/wrong with your server's configuration.

[specnyt]

Oh! And one thing, I've already uploaded my files into my server.. That was the requirement.

Here's the URL of my site..

http://www.simoonie.com/doraemon%5Fstraps/

Mmm.. I'll try out the codes you've suggested then..

[specnyt]

Well.. I made a test.php, and these are the results i got first.. Can't understand anything about it.. 🙁 about the phpinfo.. What should I look for?

[specnyt]

And I was able to remove the Unidentfied DOCUMENT_ROOT by changing the $_SERVER[DOCUMENT_ROOT] to my web address like this

$docRoot = ('www.simoonie.com/doraemon_straps/');

It took out the first notice, but the 2nd one is still there.. the REQUEST_URI one.. And there's still no images showing!

[NogDog]

The problem with the broken images is that you are specifying an absolute file system path for the "src" attribute of the <img> tag, but you need to use a web path, instead. E.g., instead of this...

<img src="E:/hosting/vhosts/simoonie.com/httpdocs/doraemon_straps/images/category/dce08605333d805106217aaab7f93b95.jpg" border="0">

...it should be something like this...

<img src="/doraemon_straps/images/category/dce08605333d805106217aaab7f93b95.jpg" border="0">

[specnyt]

Oh... I'll go and try that out.. I really appreciate the help.. I'm really really lost..

Mmm.. Is that the same problem with the notices too? It has the same absolute file path system too.. How can I fix that? Change the $SERVER['DOCUMENT_ROOT'] to $SERVER['/doraemon_straps/']?

[NogDog]

Totally separate issues, I'm afraid.

$SERVER is a "super-global" array that has many possible elements. One of those elements is 'DOCUMENT_ROOT', which normally holds the full file system path to the root web directory. If it is not set in your environment, then your PHP environment is non-standard, or you are using a really old version of PHP. If your PHP version is older than 4.1.0, then you need to change $SERVER['DOCUMENT_ROOT'] to $HTTP_SERVER_VARS['DOCUMENT_ROOT']. (Actually, what you really need to do if that is the case is update your PHP installation, or move to a server with a reasonably up-to-date PHP installation. 😉 )

[specnyt]

Hm.. Well, I checked my hosting, and they're using PHP 4.4.x.. Don't really know why its not working at all.. I modified my config.php code by doing this:

$_SERVER['DOCUMENT_ROOT'] = "doraemon_straps/";

$docRoot = $_SERVER['DOCUMENT_ROOT'];

and it actually worked.. I think.. The error hasn't popped up anymore afterwards..

Now my problem is the second notice, the Undefined index REQUEST_URI.. Now this one I'm really lost.. Don't even understand what a REQUEST_URI is..

[NogDog]

It's the same sort of thing. There should normally be a $SERVER['REQUEST_URI'] array element just like there should have been a $SERVER['DOCUMENT_ROOT']. While your server configuration is definitely not normal, the fact is that neither of those elements are guaranteed to be defined on any server (though they ususally are). As a quick work-around, I would recommend setting the values manually at the start of the script:

<?php
$_SERVER['DOCUMENT_ROOT'] = 'e:\hosting\vhosts\simoonie.com\httpdocs';
$_SERVER['REQUEST_URI'] = $_SERVER['SCRIPT_NAME'];
/* rest of script follows... */
