Capacity is a versatile framework which helps you to construct your page by focusing on the content. Your pages will be simple PHP-files which include predefined header and footer. This header/footer layout the page, you only provide the real content and menu structure.
Any normal page just contains:
<?php $page_title = "Page Title"; include "header.inc"; ?>; Content of the web page <?php include "footer.inc"; ?>
For each subsite, a site.inc in the toplevel directory of this page, which would be equal to the later documentroot on the server in many cases, may be created. This include is used by the header.inc, it should contain some information about your site, like it's name and the email address of the webmaster, this will be used by header/footer to setup the page correct.
An example site.inc would be:
<?php // promote which subdomain we are // we are www.kde.org in this case! $site = "www"; // use new style ;) yeah $templatepath = "newlayout/"; // promote title to use $site_title = i18n_var("K Desktop Environment"); // links in the top bar, right $menuright = array ('family/'=>'Sitemap', 'contact/'=>'Contact Us'); ?>
Even in the site.inc you can already use the i18n-functions, which is important to have the names right on translated pages!
The header.inc does some setup of global vars, even before it includes the site.inc, these are:
$site_root $document_root $url_root $current_relativeurl
$site_rootcontains the relative path to the toplevel of the current site, like:
$site_root = "../.."
$document_rootcontains the absolut pathname which is the documentroot of this site, even correct if the site isn't in it's own vhost, example:
$document_root = "/home/www/sites/www"
$url_rootcontains the absolute baseurl to the toplevel of your site, if your site would for example have a it's toplevel in http://127.0.0.1:8080/sites/www, like it is for staging, this would contain
$url_root = /sites/www
$current_relativeurlcontains the relative part of the current url to the url_root, would you access http://127.0.0.1:8080/sites/www/whatiskde/manifest.php and /sites/www is the
$url_root, it would contain
$current_relativeurl = whatiskde/manifest.php
BE AWARE: In former version of the framework it was common to set the
$site_root manually before including the header.inc, this won't work now, as the header.inc will overwrite the
$site_root. This should cause no danger, as header.inc should find out the right one, but in the long term, all manual definitions should be removed, the global variables header.inc exports should be used to replace the usage of the old
The framework is clever, it will never add trailing slashs to the
$url_root, therefor they can and must always be used like:
$some_url = "$site_root/mycoolpage.php"
