Question

I have a simple problem with the server global variable named : DOCUMENT_ROOT.

Here’s my config.php file :

<?php
define ('UPLOAD_DIR',$_SERVER['DOCUMENT_ROOT'].'/resouces/');

The test.php file

<?php

$photo='myimage.php';
echo '<img src="'.UPLOAD_DIR.$photo.'">';

The problem is that when testing the code.. The image doesn’t display, and the directory starts with :

C://program files/easyPHP/www/resources

instead of

http://127.0.0.1:8888/

As it supposed to be… I tried to update this line in the httpd.conf file :

DocumentRoot "${path}/www"

to

DocumentRoot "http://127.0.0.1:8888/www"

But the server declares an error :

Thank you in advance 🙂

Answer 1

$_SERVER['DOCUMENT_ROOT'] is path on your real filesystem.
You need not it here.
Just use

define ('UPLOAD_DIR','/resouces/');

Don’t mix up path on filesystem and path on your site.
They may have nothing common (but in default case requested URI sent to $_SERVER['DOCUMENT_ROOT'].URI)

You can also use

define ('UPLOAD_DIR_FILEPATH',$_SERVER['DOCUMENT_ROOT'].'/resouces/'); //to use in upload, renaming, deleting etc
define ('UPLOAD_DIR_WWW','/resouces/'); //to show URLs

You need not declare it on every levelb ecause path starts from root /
