Stefan, I have a similar thing set up for a regional newspaper firm, there is a single, 100% the same set of PHP scripts that are used throughout the system even though different sites may have slightly different layout, components etc. I use a combination of .htaccess files, mysql backend, php front end to do this. MYSQL basic config: There is a table "sites" which actually contains anything specific to a site. The key one is using a Site Abbreviation code which can then be used throughout to change logos etc (ie. siteabb_logo.jpg). This Site Abbreviation is also used as a column name in the "sections" table of which I made a short post to the list about a week and a half ago. This table allows for multiple depth of sections, sort ordering within sections etc. The CSS file is simply a PHP script that an .htaccess file tells the server to parse. In the "sites" table there is a column for 'skin' (I use basic colour names). So http://www.site.com/css/blue/default.css maps to http://www.site.com/css/default.php?skin=blue Within the PHP / CSS file the word blue then loads variables for different colour presets that are determined. This is not always efficient as sometimes a skin may not use as many alternate colours as others so you end up loading unneccesary classes (only adds a few k to the file overall though). The PHP scripts work on a modular principle and all modules are stored as functions, called when required, each standard position will generally have a fall back default with alternates offered to sites (using that site abbreviation code again) where needed. I'd be happy to go into more detail if required. H Stefan Schwarzer wrote: > Hi there, > > we're managing a (data) portal.
