Multiple-site support simplified - site administrator can define path to Wire, Site and Config files

[klor]

Re. Multiple-site support: My ProcessWire sites are hosted in an environment where I can administer multiple websites (one folder per site). I would like ProcessWire to be able to run from any (private) folder that each website can call; without having to set up symlinks. The purpose is to simplify the setup of each website installation.

For example, my applications can be named as follows:

_processwireapp

• This app only has a /wire folder with the newest ProcessWire release.

_wwww_foocom

• index.php says include("../processwire_app/wire/core/ProcessWire.php");
• index.php includes Config files from the local Site and from the Wire directories.
• The config.php files for site and wire can be over-written by local config.php files.

_wwww_barcom

• index.php says include("../processwire_app/wire/core/ProcessWire.php");
• index.php includes Config files from the local Site and from the Wire directories.
• The config.php files for site and wire can be over-written by local config.php files.

For inspiration on how other frameworks / CMS systems include application and config files, see also:

While I've not tested it here, I think that PW should let you do that. Though you will have to adjust a few of the path settings in the ProcessWireBootConfig() method in the index.php file. But it is perfectly fine to modify the index.php file. It is fine to treat index.php as a site configuration file of sorts in this manner, as it's at your discretion whether to replace it through upgrades (the index.php file rarely changes across PW upgrades).

I took a quick look into this. This change request require that the administrator can set ProcessWire variables in index.php or any other dispatch file. The variables to be modified in index.php seems to be:

    // ProcessWireBootConfig()
    $siteDir = 'site'; 
    $wireDir = 'wire';

Trouble is that PW uses relative paths in index.php ("site/...) which makes configuration of $configFile hard:

    include("$rootPath/$wireDir/config.php");
    $configFile = "$rootPath/$siteDir/config.php";
    $configFileDev = "$rootPath/$siteDir/config-dev.php";

For this reason it is not possible to "prefix" the Site and Wire directory paths with an absolute ("/www/foo_app/site/") or relative path ("../foo_app/site/").
