 Posted: Wed 27 Aug '08 17:32 Post subject: Absolute/Relative URLs help |
 |

Having a bit of an issue with absolute/relative urls. I have MAC running OS 10.5.4, Apache 2.2, PHP 5.2.5, MySQL 5.0.67 and phpMyAdmin 2.11.8.1.
Things work great, it took me a while, but I finally have all of these apps running soundfully with each other and can develop nicely. I am, however, running into an issue which I would like some help with.
I will first list my vhost settings and any other pertinent information that could help this process.
Here is the document root in my http.conf file:
| Code: |
DocumentRoot "/Library/WebServer/Documents"
|
Here are important settings in the httpd-vhosts.conf:
| Code: |
<VirtualHost *:80>
DocumentRoot "/Users/CDB/Sites"
</VirtualHost>
#IndieViz Local Site
Listen 1001
<VirtualHost *:1001>
DocumentRoot "/Users/CDB/Sites/indieViz/httpdocs"
ServerName 10.0.1.182:1001
</VirtualHost>
<Directory /Users/CDB/Sites/indieViz/httpdocs>
Allow from all
</Directory>
|
Ok, now on to my issue:
I access my development site listed at 10.0.1.182:1001 and in the index.php page are the following lines
| Code: | | include("/include/lib.php"); |
| Code: | | <img src="/img/banner_contest_269x195.jpg" width="269" height="195" border="0"> |
When the page is served, it cannot find the /include/lib.php but it CAN find the /img/banner... file.
There is both an img folder and an include folder in the httpdocs dir (the ROOT dir). So, what is the reason that /include doesn't resolve to the root, but /img does? The reason I need /include to work is that this file is included on many files deep within the site structure. I really don't want to type in ../../include and ../include every time I want to include this file, so, any help would be greatly appreciated.
I hope this makes sense, if not, please ask, I will try my best to explain.
Thanks for any help,
Clay |

The browser askd for the file in the doccument root which apache handles. PHP looks for files in the filessystem. And there is no /include/lib.php If you set there the path you have to use the relative one or use the correct absolute path like this example
| Code: |
/Users/CDB/Sites/indieViz/httpdocs/include/lib.php
|
Hope that helps. |

First off, thanks James Blond for your info. I appreciate it. I have found another solution that works as well.
I have always despised posters that don't post the solution, if found. The generous posters (PFMaBiSmAd) over at PHPfreaks have provided a solution, here it is.

An include is executed by php on the server. Unless you specify a protocol wrapper, it operates using a file system path, where a leading slash is the root of the current disk.
A src="..." is executed by a browser and it can only operate using a URL. A leading slash in a URL causes the browser to form a url starting at the domain root.
I recommend forming an absolute file system path as follows -
| Code: |
include($_SERVER['DOCUMENT_ROOT'] . "/include/lib.php");
|
|
I hope this helps someone in the future. |
