File Organization and Aliasing

[cesarcesar]

Hello all. I have been working on a Website/CMS (Engine) for a few years now. With every site i build, i just copy the current version of the Engine, make some minor changes and skin it to fit the perticular site i am building. This has worked well for a while. My problem is when i have to make an update. If i update or add an important feature to one site, usually i will need to add it to others that have the same Engine. So basically i have to waste a bunch of time updateing multiple site.

I have since learned about aliasing. So i have now seperated all my Engine into three sperate parts. (1) Site Engine. This is all site dependent files for a basic site. (2) Cart Engine. These are all files dependent on the shopping cart. (3) Manager Engine. This is the CMS for the site.

Before the seperation all files include() a *starter.php* file that initiates things like db connections, session control, and other various site dependent controls. My problem is now that i have seperated to three main Engines, only the Site Engine works. I had not forseen that the other two engines would now not have a way to connect, or know where the starter.php file is located.

My question is how can i now tell the file */path/to/ManagerEngine/index.php* that at line #1 calls <? include("starter.php"); ?>, that the file is at */path/to/site.com/starter.php*.

Ok I hope you all get what im asking. Thank you.

Use absolute pathnames.

If you use an absoute pathname, such as (assuming a unix-style OS):

include ('/var/

http://www/sitename/html/includes/a.php');

or (assuming Win32):

include ('d:/

http://www/sitename/html/includes/a.php');

then it will work anywhere. It's only relative pathnames that are position-specific.

if i call an absolute path from /path/to/ManagerEngine/index.php to /path/to/site.com/starter.php then it will only work for one site, not all.

It was suggested to rename all my starter.php to site_starter.php and put them in the "include_path" defined in the php.ini file. If this works i will post my results.

My resolution was as follows, i am using a local example. This examples updates the location of the include path in the php.ini file.

1. Add a new directory, C:\apache2triad\htdocs\includes\. (You may also use an existing *include_path*)
2. Update *include_path* in php.ini file to also accept C:\apache2triad\htdocs\include\. The include_path will be looked in first when an *include()* is called from any file in localhost.

It was that simple for the first part of my Question. The second can be found in a post called "Linking Structures".
