FolderCMS User's Manual
FolderCMS is a bit different to other content management systems: there's no 'admin panel',
and you edit your site's content by creating and modifying files directly. That means you'll need
to read this document first. Don't be put off: the system is simple to work with once you get
used to it.

What's new in version 3.3
When an active menu item is not a link (because it refers to the current page),
FolderCMS now encloses the text inside an inner span element, enabling more flexible styling.
What's new in version 3?
GD-CMS has been renamed to FolderCMS, to better describe the system.
Documentation has been converted to HTML, in line with our new internal guidelines for documentation.
Upgrading from GD-CMS version 1 and 2
This is not a drop-in replacement to previous versions. Global variable names
and functions have changed to follow a consistent naming scheme, meaning you
have to make a few changes to your index.php file to keep things working
properly. The filename of gdcms.php has also changed to foldercms.php.
directory - technical term for a folder on a computer's storage drive.
PHP - a scripting language that's commonly available on web servers for
generating dynamic page content.

Is your web server/web hosting up to it?
Your server needs support for PHP scripting. If your webspace is hosted
externally (e.g. by your ISP or by a hosting company), you almost certainly
have PHP support enabled. If you are hosting a site on your own server, you
probably still have PHP support although it may be disabled by default. Look
for an option relating to 'server-side scripting' in your server's
configuration, and make sure it is enabled.
An easy way to test if you have PHP support is to create a file in your
public web space called something like test.php
(call it what you like, but
make sure the filename ends with .php
). Put the following PHP code inside that
<?php echo 'Hello, world!'; ?>
Now navigate to the location of that test file on the web, through your web
browser (don't just open the file's location on your local computer or you'll
just see what you typed into the file). If you see
by itself in your browser window, the PHP script has been executed correctly
and done its job. But if you see the whole line of PHP code as you entered it
into the file, PHP isn't working on your server.
Find a convenient folder on your hosting server, perhaps your home directory,
preferably outside the public HTML directory where you normally place publicly
accessible web site files.
Copy the foldercms.php
file you downloaded into this folder, and also create a
new folder in the same place, called content
. This is where you'll put
the content that will make your web site informative.
Creating the template page
Now create the skeleton of a web page. Use any program you like, but leave
spaces for menus, sub-menus, sub-sub-menus (depending on how deep you plan to
go with your content), and of course the main body of your content. Non-trivial
formatting like particular menu and heading styles will require you to define
your own CSS styles for the items within those menus, although this is
something you can deal with once you have everything else working.
Call your skeleton page index.php
and place it in your server's public HTML
folder. (Most servers look for either an index.html
as the default page on your site. You don't have to call it index.php
don't want it to be the default page, or your server has alternative
requirements, but the filename must end in .php
for the PHP code you're about
to insert to be recognised.
Now open your file in a plain text editor. Add the following to the very top
of your file:
But replace ../files/foldercms.php
with whatever the path to foldercms.php is on
your server. Note that ../
means 'parent folder.'
The <?php has to be at the very start of the file. That means no blank
line or space before the <. Otherwise PHP will start sending premature
page header information which will prevent FolderCMS features like page
redirects and page-not-found errors from functioning correctly.
Specifying options (global variables)
There are some options you can specify above the include(....);
line in your
file (but after the opening <?php
$foldercms_content_path = '[path to a content directory]';
This allows you to specify a custom path to your content directory. If omitted,
the content directory is by default assumed to be named content
and in the
same directory as the foldercms.php
(If you specify a custom path, it should be a full path on your server's
filesystem, with /
between each directory, and a trailing /
at the end.
$foldercms_href_prefix = '[a URL prefix]';
This allows you to specify a prefix for the menu links on your content pages.
You won't need to worry about this unless you have specific requirements
for how the links are formatted, or you use URL rewriting with all the content
inside a virtual directory.
$foldercms_url_rewrite = TRUE;
This option instructs FolderCMS to format menu links in a way that looks neater
in the address bar. Instead of links like ?l1=Section&l2=subsection
FolderCMS will produce links like /Section/subsection
. This won't allow FolderCMS
to automatically recognise such links though. You'll still need to configure
your server to translate the neat URLs into the ?l1=Section&l2=subsection
style that FolderCMS expects.
$foldercms_url_space = '[a single character to represent spaces in URLs]'
By default, FolderCMS uses the standard convention of using the '+' character for
representing+spaces+in+page+URLs. You can specify an alternative character, such as
a '-', to-be-used-instead. In this case, it is still safe to have page titles containing
'-' characters, since FolderCMS automatically substitutes them with '+' characters instead.
$foldercms_url_lowercase = TRUE;
This option instructs FolderCMS to generate the dynamic part of the URL in all-lowercase
characters, which some people think looks neater in search results. There are no side-effects
in how these URLs are interpreted (will not break existing links) as FolderCMS interprets
URLs in a case-insensitive way.
$foldercms_double_encode = TRUE;
Some versions of Apache (web server) will lose symbols like '+' in your page titles if
you use URL rewriting on your site, breaking menu links that use those symbols. Enable this option
as a workaround if you use URL rewriting and this happens to you.
$foldercms_auth_flags = 3; //...or, another example ...
$foldercms_auth_flags = array(1, 3, 99);
You can choose one or more numerical 'auth flags' to guard certain content
with. For example, you might use the number 1
to guard pages that should
only appear on the mobile version of your site, and number 5
or categories that should only be available to users who have logged in
to your website. (Note that adding user login functionality to your website
requires extra PHP coding on your part.)
You can choose whatever flag numbers you like (the above examples are just
arbitrary), but if you want to specify
more than one flag at once, you need to place array( ... )
around your list
of 'authorised' flags, as in the example above.
Adding placement code to your skeleton file
Now, inside the code of your index.php page, place the following...
<?php foldercms_place_title(); ?>
anywhere you want the title of the current content page to appear. One good
place is between the <title>...</title>
in the head of the HTML code
(so the correct page title appears in your web browser's title bar).
<?php foldercms_place_content(); ?>
where you want the body of the content to appear.
For the menus, place
<?php foldercms_place_menu(1); ?>
where you want the main (top-level) menu to appear,
<?php foldercms_place_menu(2); ?>
where you want the sub- (level 2) menu to appear, and so on. You can have as
many levels of submenus as you like.
By default, menus are generated with a space in between each menu items.
You can have anything you want between each menu item, by supplying an optional
parameter; for example...
<?php foldercms_place_menu(2, ' | '); ?>
...will cause FolderCMS to separate | items | like | this.
Similarly, placing <br />
(an HTML line break tag) between each menu item,
will cause each menu item to be on a separate line.
Note: You can also use a CSS stylesheet to format your menus.
Each menu item is given a unique ID (which you can inspect by viewing
your page's source code) to give you fine-grained control.
If your content includes cascading template files, use the following to insert
them into the appropriate place in your page code:
<?php foldercms_place_template('[template title]'); ?>
If a particular template file isn't available, this function simply has no effect.
To add breadcrumb navigation to your site, use the following where you would
like the breadcrumb navigation links to appear:
<?php foldercms_place_breadcrumbs('[separator]'); ?>
...where [separator] is whatever symbol(s) or HTML code you want to appear
between each link.
To help promote FolderCMS, use the following near the bottom of your site to add a
short 'Powered by FolderCMS' message to your page (you don't have to, but we do
<?php foldercms_place_promo(); ?>
Most of the above placement functions can also be used inside your content
files and templates. Just avoid things that cause recursion, like placing
foldercms_place_content(); inside the content itself.
Adding content to your site
Inside your content folder, create files and folders according to the following
To make a new site category, create a folder called
1.Name of category, or
2.Name of category if slot 1 is already taken. Obviously, replace Name
of category with your own category title. You may use spaces and various other
To add a page of content, name the file in a similar way:
1.Content title.txt .
Note: Your content pages can have any filename extension you like (not
necessarily .txt). For example if you have a PHP code editor that
you want to edit your content files in, you may find it more convenient to
name your files, 1.Welcome.php, etc.
The number followed by the period represents a index number within the current
folder. Each index can only be used once, and a category folder can't use the
same content title as a content page within the same parent folder. The numbers
represent the order in which the menu options are presented.
Writing your content
Within a content file, just write your content out using a text editor, using
HTML markup tags for formatting
If you're new to HTML markup, refer to the included HTML markup reference
file for a convenient one-page summary of basic formatting tags.
You can place one or more of the following designators in your content
filenames, directly after the index number, but before the first period '.'
in the filename. Some designators allow you to omit the menu index number
entirely. This means that the item won't appear in the menu, but you may still
be able to access it with a direct link.
d – default
Using the d
specifier means that item will be selected by default when the
user clicks on the parent category. Naming a file d.Your title here.txt
without the menu index number, means that that content page won't show up in
the menu separately, but instead will be treated as the default content page
within its parent category.
h – hidden
instead of (or after) an index number makes a content page or category
hidden. It will not be displayed in menus, however users can still access the
page or category if they know its URL.
r – redirect
This allows you to include links to external websites in your content menus
(For example 4r.Blog.txt
). Inside the file, instead of writing actual content,
write (on a single line without spaces) the URL of the web page that you want
that item to redirect to. Begin the URL with http://
if it's an external
a... – auth flag
followed by a number allows you to specify that a content file should only
be used if a particular auth flag is set. You can specify that more than one
are required, for example, 2a1a3.Restricted Category
will only be
available and visible in the menu if auth flags 1
without a flag number means the content will be available if at
least one auth flag is set, regardless of the flag number.
If auth flags are set,
content that requires auth flags will take priority over content that doesn't,
so you can override default menu items with alternate content if required.
t – cascading template
You can provide things like extra layout code which apply to a particular
category (and 'cascade' down to subcategories) in order to give one corner
of your website a unique look, for instance. For example, you might have a
file in your root content directory, and override it with
a different t.header.txt
file in a particular subcategory. To apply this
particular template, you would use
<?php foldercms_place_template('header'); ?>
in the appropriate place in your index.php
Cascading templates are only really needed
if you have different layout requirements in different subcategories.
e401, e403 or e404 – custom error content
You can show users a custom content page when an error is generated.
This must be a content file, not a folder or a redirect.
