Question What are redirects and how can I use them for subsites?
Answer Redirects let you create custom URL paths that point to different zones and pages within your site.

Examples:
  • Sharing modules across zones: Create a redirect to make a module in one zone appear in another.
  • Creating shortcuts: Use a redirect to point a short URL to a longer, more complex URL.
  • Moving pages: Use a redirect to ensure old links still work after moving a page to a new location.

Go to Admin Zone > Structure > Redirects.
Question What are virtual roots and how do I use them?
Answer Virtual roots let you make a sub-category within a Composr module (e.g., downloads) appear as the top-level category. This is useful for creating separate "databases" of content for different subcommunities.

To create a virtual root:
  • Enable "Virtual root links" in the Admin Zone > Setup > Configuration > Feature options > Advanced.
  • Navigate to the desired category while logged in as staff.
  • Click the rightmost link in the breadcrumbs (it will be an anchor for virtual root creation).
  • Use the resulting URL in your menus to link to the "virtualized" category.
Question Can I have subsites and subcommunities within a single Composr installation?
Answer Yes, Composr offers various tools to create subsites and subcommunities within a single installation:
  • Zones: Create separate sections under different URLs with their own pages and content.
  • Redirects: Make modules appear in different zones without actually moving them.
  • Categories & Virtual Roots: Organize content like galleries, downloads, and catalogs into sub-trees that appear as separate entities.
  • Usergroups & Permissions: Group members into subcommunities and control their access to specific content.
  • Themes: Customize the look of different zones.
Question What is the difference between a central site and a satellite site in an M.S.N.?
Answer The central site hosts the shared forum, member database, and netlink system. It is the core of your M.S.N.

Satellite sites are the additional websites within your network. They connect to the central site for member information and forum access.
Question What are the advantages and disadvantages of using an M.S.N.?
Answer Advantages:
  • Full control: You have complete control over each site's settings and content.
  • Administrative separation: Managing staff and content for each site is more organized.
  • Special M.S.N. features: Composr provides specific features like the 'netlink' system for easy navigation between network sites.

Disadvantages:
  • Configuration and maintenance: Setting up and maintaining multiple sites can be more complex.
Question What is a multi-site network (M.S.N.) in Composr?
Answer An M.S.N. allows you to run multiple Composr websites (installations) that share a common forum and member database. It's ideal for website networks with shared communities but segmented content, staff, or branding. In essence, members who join one site automatically have accounts on all sites within the network.
Question What are the key classes and utilities provided by Composr Mobile SDK?
Answer CMS SDK provides several classes with utility functions mirroring PHP and Composr APIs, including:
  • CMS_Arrays: Array operations (e.g., implode, explode, list_to_map).
  • CMS_Strings: String manipulation (e.g., strip_tags, html_entity_decode, strpos).
  • CMS_Langs: Localization functions (e.g., do_lang).
  • CMS_Preferences: User preference management.
  • CMS_Timestamps: Timestamp functions (e.g., get_timezoned_date_time, time).
  • CMS_HTTP: Web service interactions (e.g., rawurlencode, json_decode, http_get_contents).
  • CMS_Users: User data and permission checks (e.g., has_page_access, is_staff).
  • CMS_Flow: App flow control (e.g., access_denied, attach_message).
  • CMS_Forms: Form building and management.
  • CMS_Database: SQLite database access and manipulation.
  • CMS_Notification: Push notification handling.
  • CMSNetworkManager: Network request execution and response handling.

Question How do I set up the system scheduler in Composr?
Answer The system scheduler is crucial for scheduled tasks like sending notifications, running backups, and processing reports. To set it up, you need to schedule a system-level task to run the data/cron_bridge.php file at least every 10 minutes. This links Composr's scheduler with your server's scheduler (like Cron on Linux).

Composr can often detect the correct command to use for your setup. You can check by visiting http://yourbaseurl/data/cron_bridge.php?query_mode=1, which should display the suggested Cron command. Note that you may need to replace the php command with the absolute path to PHP if you cannot use the php command directly.

If your hosting doesn't support Cron or scheduled tasks, you can enable scheduled tasks to run when visitors access your site. Navigate to Admin Zone > Setup > Configuration > Performance options and check "Web requests run scheduled tasks". Keep in mind that this method relies on visitor traffic and isn't as reliable as a dedicated scheduler.

Alternatively, consider using external services like EasyCron, setcronjob.com, or onlinecronjobs.com. These services allow you to schedule calls to the data/cron_bridge.php script by URL at specified intervals.
Question What are the different security levels in Composr's Setup Wizard and what do they affect?
Answer Composr offers five security levels in the Setup Wizard: Minimum, Low, Medium, High, and Ultra High. Each level sets various security configurations that you can later customize under Admin Zone > Setup > Configuration.

The security levels influence settings such as:

  • Content Security Policy
  • Session expiry time
  • Password reset process
  • Password expiry days
  • Minimum password length and strength
  • Login error secrecy
  • IP strictness for sessions
  • Cryptographic ratchet
  • CAPTCHA usage
  • Brute force threshold
  • Audio CAPTCHA
  • URL Monikers
  • .htaccess restrictions on maintenance scripts
  • Enquiry on new IP addresses

The higher the security level, the more stringent the security measures, with Ultra High offering the most robust protection but the most potential inconvenience to users.

Generally, you should use these settings depending on your site:
  • Minimum: Very bare-bones informational-only sites
  • Low: Sites which do not allow public registrations and do not use eCommerce but have content managed by different staff, and are not concerned with privacy or data
  • Medium: Sites with social features / public accounts but do not use eCommerce.
  • High: Sites which use eCommerce.
  • Ultra High: Sites containing very sensitive data, such as but not limited to cybersecurity sites, government departments, banks, healthcare, etc.
Question How do I change my website's logo?
Answer You can change your site's logo manually or by using the Logo Wizard. To change it manually, go to Admin Zone > Style > Themes. Choose "logo/-logo" from the dropdown list, which represents the logo for the Welcome Zone and any zone without a specific logo. Replace the current image by uploading a new .jpeg, .gif, or .png file. Ensure that the 'Name' field remains unchanged.
Question What are Composr addons and how do I manage them?
Answer Composr is built using a series of addons that provide different functionalities. All "bundled" addons are installed by default. Once you are familiar with Composr, it's recommended to remove any bundled addons you don't need to simplify your site and prevent accidental exposure of unconfigured features to visitors (the Setup Wizard can also uninstall these addons based on your preferences). You can manage addons by navigating to Admin Zone > Structure > Addons. Uninstalled addons are archived and can be restored later, but any associated data will be permanently lost.

Composr also offers non-bundled addons. These addons are not bundled because they are not considered mainstream, rely on third-party services, haven't been vetted to Composr standards, or don't fully conform to those standards.

You can install non-bundled addons by going to Admin Zone > Structure > Addons, scrolling to the bottom and clicking "Import non-bundled addon(s)". You will need to browse to the addon file and click the import button. Once imported, review the warnings and proceed to install the addon.

You can also download and import addons from this website under the Downloads section.
Question What are some of the default Comcode pages in Composr?
Answer Composr includes several default Comcode pages, each serving a specific purpose:

  • home (Welcome and Site zones): The default front pages for the respective zones.
  • sitemap (Welcome zone): Displays the sitemap, typically generated automatically.
  • _rules (Welcome zone): Outlines the site rules, also displayed during registration. The "rules" page (no underscore) is a wrapper for this page.
  • privacy (Welcome zone): Provides privacy policy information. By default, this is generated automatically with Composr's privacy policy generator block.
  • 404 (Welcome zone): The page shown for 404 errors (page not found) and includes a sitemap.
  • help (Site zone): Contains general help information.
  • userguide_comcode (Site zone): A basic guide to Comcode for users.

Remember that you can edit these default pages or create entirely new ones to tailor your site's content to your specific needs.
Question How do I hide a Comcode page from the sitemap?
Answer If you want to prevent a Comcode page from appearing in your sitemap, you can simply prefix its name with an underscore (_). For example, pages named "_test" or "_example" would be excluded from the sitemap. Note that this generally does not hide the page from your site itself (to do that, use the validation addon to turn validated to "OFF" for the pages); it only hides them from the sitemap / search engines.
Question Can I organize Comcode pages in a hierarchical structure?
Answer Yes, Composr allows you to simulate a hierarchical structure for your Comcode pages using multi-part paths in the page monikers. By editing the page monikers to include slashes (e.g., "about/team"), you can create a virtual directory structure within a single zone, enhancing your site's organization and navigation.
Question How do I embed content from other modules into a Comcode page?
Answer You can use various blocks to embed content from different modules:

  • main_content block: Allows you to feature individual entries from modules/content like news or articles.
  • main_multi_content, main_cc_embed, main_gallery_embed, main_news blocks: Enable you to pull in and display multiple entries based on categories or other criteria.
  • main_include_module block: Provides a powerful way to integrate any module screen directly into a Comcode page.
Question What is the difference between blocks and boxes in Composr?
Answer While both terms may seem similar, they have distinct meanings in Composr:
  • Blocks are functional units that generate dynamic content or provide specific features. They don't inherently have a visual form and their output can vary widely.
  • Boxes are a visual design element in Composr, essentially containers that visually group content on a page and often with a title at the top.

In practice, blocks often place their content within a box, but this isn't a requirement / standard.
Question Can I customize the appearance of blocks?
Answer Yes, you can customize the appearance of blocks by editing the associated templates and CSS. Each block typically has a corresponding template file (e.g., BLOCK_MAIN_NEWS.tpl for the main_news block) that controls its HTML structure. You can modify this template to change the layout and styling of the block's output.

An easy way to do this is through the template editor in Admin Zone > Style > Themes, and click edit templates for the relevant theme.
